Gas stove for summer cottages with a cylinder. Is it worth using a gas heater in the country, which model to choose Household gas ovens for cooking

Heating a private house is one of the main concerns for the owner. Choosing a heating device, the owner puts forward the requirements of practicality, durability and ease of use, the cost of maintenance is also an important factor. A simple gas oven meets all the parameters. We will understand the nuances of choosing a device, the characteristics and features of the operation of gas heating.

In this system, the coolant is gas, therefore, in addition to heating devices, the structure includes gas pipelines for fuel supply, heat release, shut-off and control valves, and automation for safe fuel consumption.

Main gas can be used for heating. The system is centralized, unified; fuel is supplied to the consumer through pipes. There is also the option of using liquefied gas supplied in cylinders of different volumes or poured into gas tanks.

Advantages and disadvantages

Experts note the following advantages of using a gas oven:

1. Operation at any time of the year, day and night. A gas heating stove in the house does not interrupt, it is only important to take care of the presence of the heat carrier itself.
2. Increased efficiency. The devices provide a comfortable temperature in the house in any climatic conditions, including in severe winter frosts.
3. Convenience. Unlike solid fuel boilers, gas units do not require a lot of space, raw materials are relatively cheap, and you do not have to equip a separate room for storing them.
4. Ease of operation. With a properly designed control system, all work is reduced to pressing a button that starts the equipment. Prevention and maintenance costs are kept to a minimum.
5. Durability. The gas oven for the home is one of the longest-used appliances. The warranty period is 10 years, and subject to the installation and application technology, the device will last much longer.

The main disadvantage is the high price. But the minus is leveled by the low cost of fuel, the long service life of the system.

Varieties of gas ovens

Devices differ by type of fuel, heat capacity, shape and other indicators. The equipment consists of several elements: body, chimney, foundation. In the body there is a heating shield, a firebox, a gas burner. The burner is a replaceable element that can be one-, two-stage and have a floating adjustment. If desired, the owner can easily replace the burner with a more or less powerful one.

Fuel type

The main supply of fuel is considered more practical, in this case you will not have to freeze if the cylinder is forgotten or did not have time to refuel. For regions with gas supply interruptions, experts recommend choosing combined devices that run on all types of fuel: solid, liquid. The equipment is more expensive, but the positive properties quickly pay off the price of the units.

Important! Liquefied gas, coal, wood, fuel oil, diesel fuel are used as fuel for combined furnaces. The characteristics of the products are selected depending on the user's requirements.

Heat capacity of the furnace

The parameter differs in the ability of the structure to accumulate and release heat.

Ovens should be chosen for their intended purpose, that is, for continuous or intermittent operation:

1. Ovens with a regular heating cycle are made of metal with thin walls and cannot store energy. The advantage is fast and uniform heating of the room. The downside is the consumption of a large amount of fuel. But it is precisely the systems of a constant heating cycle that are more effective for periodically heating a room. For example, if the house is used only during the season, and in winter the owners come only for the weekend, then a constant-heating gas oven will be more appropriate than all other units.
2. Intermittent switching devices look like stationary ovenslined with brick or heat-shielding reflective screens. The design works on automation, it turns on when the set temperature level in the room drops, and as soon as the air warms up to the desired parameter, the stove turns off.

Manufacturing material

The duration of operation of the device, the cost and heat capacity of the furnaces depend on the material of manufacture.

There are several types of equipment:

• Cast iron gas stove for heating with a fire compartment door. The door can be made of fireproof glass, the firebox itself is used to supply coal and firewood. The price of the device is high, the payback is fast, and the operation is very long.
• Heat resistant or stainless steel construction. The advantages of the furnace are the efficiency of heating the room, the longest possible service life, and a relatively low cost. Minus only in low heat capacity.

Some craftsmen make gas ovens independently, choosing sheets of iron of the required thickness, then covering the furnace with bricks. The equipment will last a little less than cast-iron models, and in terms of price and basic characteristics of the product, it is much better than some industrial designs. Minus - it is difficult for a beginner to master the task without experience.

Types of ovens by purpose

The characteristic divides the units according to the type of work - in houses with permanent residence or irregular inclusions to supply heat. For year-round mansions, periodical devices are suitable, for rare visits - continuous heating cycle furnaces.

The main purpose of the unit is to supply heat to the premises. Depending on the requirements of the owner, the devices can be with constant temperature support (automatic on / off) or quickly heat the room, but then require the participation of the owner to restart.

How to choose a gas stove for your home

What to look for:

1. Power. The temperature indicator in the house depends on this parameter. The power of the burner, the heated area, the number of windows, doors, wall thickness, roof integrity are taken into account.
2. Equipment. Manufacturers equip systems with adapters, which allows the unit to be connected to multiple fuel sources. But this design is suitable for houses no more than 2 floors in height, otherwise the efficiency of the system decreases.
3. Method of generating heat. Furnaces with burners show higher productivity than catalytic ones. The latter are recommended to be installed in houses with a small area, the power of the catalytic furnace is not more than 4.9 kW.
4. Burner type. The simplest is a single-stage burner, independent from the power supply, with automatic switching on and off of the device. Two-stage burner - a device operating in 2 modes, makes it possible to save up to 40% of the nominal value. This means that while there are no people in the house, the stove will operate in a reduced mode, saving fuel. A continuously adjustable burner is expensive, but it allows you to quickly change the heat supply mode.
5. Air supply to the furnace. The atmospheric ventilation of the combustion chamber is different, in which air is supplied in natural mode, the efficiency is 90%. And there can be an inflatable system, where air is forced, the efficiency is 95%.
6. Fuel combustion chamber type. A gas stove with an open combustion chamber takes air from the room, but the exhaust gases also go into the room. The stoves are mobile, comfortable, but require good ventilation of the room. A closed chamber is a more practical option in which a chimney is equipped. Furnaces do not burn oxygen, so they are better suited for permanent homes.

If the gas stove in the house is equipped additional sensordetecting the level of carbon dioxide, the device will automatically turn off when the dangerous level is exceeded - this is very convenient when there are children in the family. It is strictly forbidden to purchase units that are not intended for installation in residential premises. Before purchasing, you need to request documents for the device, carefully read the instructions from the manufacturer.

We calculate the gas consumption

To determine the fuel consumption, you need to know two parameters: the power of the device and the heating area. The calculation is carried out as follows: 10 m2 of living space should have at least 1 kW of burner power. It is better if the gas stove works with a margin of 15-20%.

Now it is necessary to calculate: the generation of 1 kW of power requires 0.112 m3 of gas. That is, to heat a room of 50 m2, (5 kW x 0.112) 0.56 m3 of gas is required for 1 hour of operation of the unit. Having found the desired figure, it is easy to carry out calculations for the required volume of fuel per day, heating season. From the above example: 13.44 m3 of gas is required per day, 403 m3 of gas for one month of continuous operation of the furnace.

On a note! Taking into account the power reserve for a house of 100 m2, a stove with a capacity of at least 12 kW should be installed.

Gas is one of the benefits of civilization. If it is available, why not choose it as the fuel for your sauna stove?

Let's look at all the pros and cons of this step.

Gas stove for a sauna or bath?

Time does not stand still: more and more steam lovers understand not only the significant difference between the national baths of neighboring peoples, but also the fact that the conditions of these baths are demanding on heating equipment, room arrangement and other components.

Hence the question: in which of the baths will the gas stove be appropriate? And is it really contraindicated for another?

The answer is pretty simple: gas is just fuel, and the real meaning for your bath will be the material from which this stove is made.

After all, it will not be a big discovery for you that a gas burner can be put not only in a metal, but also in a brick oven?

But not every brick oven is suitable for gas. What are the limitations?

1. The combustion chamber should not be too large, but also the torch from the burner must not touch the furnace material.
2. A stove is not suitable without a smoke circulation system. The scheme is good dutch or swedish stoves.
3. Bell-type ovens too not an option to switch to gas, because the gas combustion product will not be retained under the bell, it will be carried out into the chimney, and the task of the hood is to have time to take away the heat. In this case - will not have time.

Least suitable for Russian bath will be without shielding... But with a solid brick is also a perfectly acceptable option.

Concerning saunas, then she needs fast and strong convection... Hence, the best ovens there will be those who do not interfere with the free heating of fresh air flowing through from the street - this is either a metal stove without external finishing with an open stove, or the same stove in a casing-mesh.

Gas as fuel behaves in a sufficiently controlled and predictable manner if do not violate the instructions for use. Therefore, you can get the specified conditions without surprises.

For a better understanding, let's consider this:

Gas oven device

The above, as it were, hinted at the fact that a gas stove is not much different from a wood stove. And indeed: if you wish, you can remake an existing wood-burning stove by placing a gas burner in it.

Note! There are restrictions, for example, it is better to set microflame burnerso that the metal does not burn out, care must be taken that the flame does not touch the walls and top.

The internal heater can also become a source of problems - flowing or closed, it not designed for a torch temperature of 1600 degrees.

Keep in mind! Even when the entire gas is burned in air, problems remain. After all all the heat goes up, and the lower part does not heat up... Therefore, the steam room heats up unevenly, which means it takes longer.

By the way, the dimensions of the fuel compartment in the initially gas-fired oven will still be smaller than in the wood-fired one, but this is understandable - the firewood is voluminous, so additional space in the firebox was allocated to them. And the gas does not need so much space. He only needs air.

IMPORTANT! But this is a really significant point: for complete combustion, the gas needs an inflow of fresh, oxygenated air... Because any combustion is oxidation, interaction with oxygen. If it is not enough, combustion will be incomplete, and incomplete products are dangerous to humans!

To better understand this issue, let's look at the structure of the main part of a gas sauna stove:

Gas burner device

Today burners are of two types:

• atmospheric;
• supercharged.

Atmospheric

Cheap type of gas burnerbecause it's simple enough. It is a tube or tubes through which one or another natural gas flows under pressure. Before burning, it must mix with air, and air in this type of burners is supplied solely by means of a draft. And if there is no proper ventilation, then it is better not to experiment with such burners.

Well, if you are sure that you have good ventilation, the draft will work properly, then the atmospheric burner will be good - it is silent, does not depend on electricity.

Truth, it depends on the movement of air in the room itself - this changes the proportions of mixing gas and air. The result is uneven heating. And the efficiency suffers - a lot of heat goes into the pipe in the literal sense. In addition, gas combustion is often incomplete.

Inflatable

The second type differs significantly from the first in design. The meaning of the differences is that in order to make the traction even... This requires a fan, which means electricity.

As in the atmospheric burner, the gas must first be mixed with air in a forced draft burner. The fan is adjusted so that the ratio is optimal. When this is achieved, dependence on air movement in the steam room disappears, and with it unevenness in the formation of a mixture and its combustion.

The advantages and disadvantages are worth mentioning right away. blowing or ventilator (yes, these are also options that constructively represent the same thing). It is clear that dependence on electricity is difficult to attribute to advantages.

IMPORTANT! If someone has problems with electricity, then it is better to secure the gas oven fan. emergency power supply.

The second, less important drawback is noise. The third is the cost, which is 2-3 times higher than the cost of an atmospheric burner. As for the latter, then it is worth considering how quickly the choice will pay off, because the pressurized burner also has a big advantage: it is twice (!) more economical than atmospheric.

In addition, forced draft burners are normally installed in wood-burning stoves. But here it is up to the owner to decide, because converting a wood-burning stove to gas can significantly reduce its operating life due to metal burnout.

One more advantage is worth mentioning: the ability power settings.

Work pressurized burners from both main gas and liquefied... Moreover, the transition from one type to another is quite simple.

Video

For a better understanding of the subject, watch the video that clearly demonstrates the operation of a pressurized burner installed in a metal sauna stove.

As you can see, not everything is so simple with a gas stove, as the sellers say. Therefore, it is worth comparing the merits of all existing types of ovens.

Comparison of gas, wood and electric stoves

Disadvantages of gas

1. Gas ovens are not only a fire hazard, but also an explosion hazard. Therefore this the only type of ovens to be approved.
2. Since a gas stove can be both metal and brick, the issue with is solved solely depending on the weight of the entire structure, including the chimney.
3. If the stove is metal, sooner or later it will burn out - with wood or gas. However, since gas it will happen faster.
4. According to requirements fire safety repository for gas cylinders must be a separate building.
5. The permit implies not only an inspection of the equipment by a gas inspector, but also a bypass various instances.

Advantages of gas

1. Simplicity power control. Given that the maximum efficiency is maintained even if the power is reduced to 3-5% of the nominal. The wood-burning ones cannot boast of anything like that.
2. Exactly set temperature - a plus that electric ones also have, but are absent from.
3. Reduced preparation time baths - in about forty minutes you can start children and women, and after a couple of hours the steam room goes “on mode” (! about the steam room stoves).
4. Compared to wood burning: practical no soot and soot, no preparatory work with fuel, higher furnace efficiency.
5. Compared to electric: gas cheaper electricity.

Disadvantages of wood burning

1. First of all annoying time to be spent to ensure that the bath went "on mode". Depending on the furnace material, it can be 4 or 6 hours. Metal, of course, will warm the steam room much faster, but this.
2. Another big drawback is dirt associated with regular cleaning - from the ash pan to the chimney.
3. It is also worth mentioning that the fuel must be prepared in advance, because different brands of stoves consume logs of different lengths, so it is not enough to chop firewood, they still need to be cut in the necessary lengths.

Advantages of wood-burning

1. considered traditional, therefore, the inconveniences associated with it are accepted as a continuation of its advantages. First of all, we are talking about fans of the Russian bath, who value a wood-burning brick or brick-lined stove as a source of uniform, soft heat, while inside the stove they are heated up to 400 degrees to give light steam.
2. Those who are more interested in “just washing”, of course, do not see the point in studying the intricacies of the art of a stoker and a bathhouse attendant, but they are also able to appreciate a wood-burning stove as the least costly both in purchasing and supplying it with fuel.

Disadvantages of electrical

1. Of course, you do not need to get a permit for an electric one, as for a gas one, but if the stove is not the weakest, you will have to pull three phases to get 380 volts. A good electrician will explain whether 220 V can be dispensed with in a particular case or there are no options.
2. It may be necessary to change the wiring to a thicker cable.
3. The cost of electricity is the highest among other fuels.
4. Rare is either an expensive "thermos" or a Russian invention with a steam generator hidden in an open heater.
5. Do not pour a lot of water and wet the heating elements.
6. Heating elements generally fail easily.

The advantages of electrical

1. Perfect.
2. Heats up quickly.
3. Takes up little space.
4. It does not need a foundation or a chimney, and therefore at the construction stage you can not really think about where it will stand.
5. If, after this list of advantages and disadvantages, you still decide that gas is more suitable for you than others, let's see what you need to focus on when choosing it.

Sauna gas heater: which one to choose?

There are several selection criteria, each of which should be considered separately.

Power

Powerful gas stove for very large saunas

This is the parameter of heat release per hour of gas combustion. The power is different:

• nominal;
• minimum;
• maximum.

The latter two define the boundaries of the stable operation of the burner while maintaining its safety. The rated power determines the maximum value of heat generation during continuous operation... This takes into account the excess air, which should be minimal, and the incompleteness of fuel combustion, which should remain within the specified limits.

The burner power is indicated in its passport... Our task is to calculate how much energy is needed to heat a particular steam room. Of course, for this there is a simple calculation with coefficients:

• we calculate the volume of the room;
• we measure the area of \u200b\u200bsurfaces devoid of thermal insulation - tiles, etc. We multiply their surface area by 1.2 and add the resulting figure to the volume of the room calculated above;
• in a log house without thermal insulation, the increasing coefficient for the entire volume is 1.5;
• if, we add another one and a half cubic meters to the calculated figure.

Let's summarize the results. The final figure is the number of kilowatts required to heat our premises. It remains only to compare with numbers rated power vending burner.

By the way, in further calculations, you can proceed from the fact that a gas heater for a sauna with a capacity of 10 kW will burn 1 cubic meter of natural gas per hour or 0.85 kg of liquefied gas.

Burner type

Above we have already talked about what kind of burners are. It's time to choose the right one.

Let's start with the fact that the cheaper atmospheric can only be placed in premises with a volume of more than 12 cubic meters... This is due to the need to ensure sufficient air flow to the burner. And people should have something to breathe).

Attention! The smaller the volume of the steam room, the more correct it is to take supercharged burner. In addition, it is more suitable for various types of existing stoves (if you transfer the wood burning to gas).

And if you intend to use firewood from time to time, and not just gas, then atmospheric for you - not an option.

By the way, it is worth mentioning that in addition to purely gas burners there are also burners of the so-called "combined type", which implies the possibility of working as on gas, so and diesel fuel... If anyone has interruptions with gas, then this is their option.

And now the most important thing: when choosing a gas burner, you need to look, whether it is specifically designed for sauna stoves or not. And it is better if it is still intended. Their difference is that they are longer, than usual. This is done in order to put them in. And the use of others in the case of a gas bath stove is not recommended.

IMPORTANT! The gas stove in the bath must be heated exclusively from the dressing room!

Automation

Automation in a gas oven is designed not only to simplify its control, but also ensure the safety of peoplelocated in the room (not to mention the safety of the room itself). therefore you should not neglect it.

What automation can be purchased for which burners?

Atmospheric burners are the simplest, but they can also be equipped oxygen concentration sensors, which can independently turn off the gas supply in the event of a strong fall. This will protect people from incomplete combustion products.

Useful video

But in this video shows not only how to ignite an atmospheric burner, but also how the device that shut off the gas works when the flame goes out.

IN supercharged more automatic burners: it responds for switching off the gas in cases of a decrease in its pressure in the network, a power outage or the extinction of a flame.

Also, all gas ovens are supplied with thermostatswho support set temperature... These devices also belong to the automation we are considering.

Nuances to consider before installing a gas stove

We have not touched on the topic in any way self-made gas oven for one simple reason:

IMPORTANT! Homemade gas ovens and gas burners not certified, they are legally prohibited for use... In case of violation, you will have to pay fines.

The only thing in your power is buy a finished burner and prepare the stove for gasification. The following standards should be checked:

• the firebox must (!) go into the dressing room, and the opening of the firebox is finished with iron;
• dimensions of the furnace opening: 47-55 cm in height, 35-45 cm in width, and if together with a metal frame, then 61-68 and 51-66 cm, respectively;
• the minimum volume of the room for installing a gas oven is 8 cubic meters. (Remember, yes, that atmospheric ones are set with a volume of at least 12 cubic meters);
• the height of the room cannot be less than 2.2 m;
• a window with an area of \u200b\u200b0.6 sq. meter, slots under 4 cm or ventilation grill;
• the refractory material under the stove must be at least 10 cm wider than the dimensions of the stove on each side;
• flammable walls should not be closer than half a meter to the heating device.

IMPORTANT! All work related to gasification is underway professionals.

Documents that need to be issued for the operation of a gas bath stove

fire certificate for gas oven

The first document that you must have is certificate for purchased equipment: burner or oven... What is bought in the store already has such a certificate.

Another important thing is that the delivery set of the burner may include a hose with a reducer and other parts for connecting to cylinder gas, which, if desired, can be purchased separately, but here you need to know that with a separate purchase, each part will need a certificate. This will complicate the procedure for obtaining permission.

When the equipment is installed but not yet connected, you need to call the inspector for an inspection... He should check everything and, if necessary, indicate what needs to be corrected. After receiving the result of the inspection, a bypass of other instances begins, the result of which will be the receipt permission for the operation of the stove, which is issued by Rostekhnadzor.

The requirements for atmospheric models are stricter than for supercharged ones. In addition to fire safety measures and chimney insulation, as well as the presence of a spark arrestor at the end of the pipe, which applies to any type of burner, will be checked thrustand ventilation device.

The most famous Russian companies producing gas ovens

We are not interested in promoting any of the manufacturers, therefore we simply inform that the Russian enterprises "" and "Termofora" have ready-made gas ovens:

"Teplodar"

"Termofor"

***
Well, if you were not scared by the hassle of paperwork, a gas stove can really save a lot of labor and money (this is later, and at first you will have to spend well). But don't forget the main thing - oh security, because today we have all the means to prevent the explosion of domestic gas.

Where can one buy

Even more models of gas ovens are presented on the official websites of suppliers, some of the companies are collected in the "" section.

In contact with

Every factor plays a big role. Therefore, it is important to plan carefully the conformity of the installation parts. The heating system includes thermostats, connection system, air supply, manifolds, batteries, fasteners, expansion tank, boiler pipes, pressure-increasing pumps. On this page of the Internet project, we will try to determine the necessary structural units for the desired cottage. The home heating system has important devices.

With the onset of cold weather, each owner of a summer cottage decides the issue of organizing the heating process. And the owner of the dacha solves several important tasks - this is also a question of safety, economy, personal taste and, of course, common sense.

After all, most heating systems cost a lot of money, and the dacha does not always need constant heating. The best choice would be a practical gas stove for summer cottages. In addition, heating gas models for the home are safe, due to the fact that gas liquefaction in them occurs without a flame.

The cottage will be heated thanks to the special principle of the furnace, where the gas oxidation process takes place on the gas panel, due to which a large amount of heat is released.

Also, gas stoves do not burn out oxygen and do not depend on periodic voltage drops. But what type of heating stove for a house to choose will depend on the characteristics of each type.

From the burner to the boiler - the differences and advantages of the types of furnaces

Choosing for yourself the optimal model for heating, remember that the device can operate on different types of fuel - liquefied gas (it is supplied in standard cylinders and all types of heaters function on it) and natural (used only in those furnaces where a special removal of combustion products is implied ).

The first fuel option is the most rational for a house, summer cottage or bathhouse, and the second is used most often on an industrial scale.

1. The most popular gas stove that is purchased for a summer residence is a gas burner... This device is very simple, it consists of a heat exchanger, a fan, a casing and a burner. Here the heat is transferred to the air by a heat exchanger, and the liquefied gas is fed to the burner, where it combines with oxygen. This is how the heating process takes place, after which warm air is "transferred" to the room with the help of a fan.

• The burner can heat up to 60 sq. m area.
• The burner power depends on its size and can be up to 3000 W.
• The disadvantage of this type of oven is that powerful burners can dry the air.

By the way, it is gas burners that are used to heat the bath, so this fuel is more economical than wood and electricity, and more convenient in the process of use - it is enough to set the burner on fire and you can enter the bath in an hour. For taking bath procedures, a 2000 W gas burner will be enough.

You can buy powerful 3 kW gas burners in the bathhouse, but use less "voracious" ones for heating stoves at home. True, if you look at the reviews about such models, the burners cope only with small bath rooms and quickly "lose" heat.

Burners are suitable only for quick bathing procedures. You can buy burners for a bath for $ 100. and the price of a gas burner for a summer residence starts at $ 30. The cost will depend on the level of fuel consumption and burner power.

Gas convection oven

Such a heating model is popular among summer cottage owners due to its rational power and mobility. It is these two parameters that mark all reviews of convector models. Convectors can operate both on natural and "balloon" gas. Their main advantages:

• High power - up to 6000 W
• Easy installation and the ability to move the device to any room
• Effective heating up to 80 sq. meters
• The presence of a thermostat that regulates the intensity of the gas supply depending on the set temperature level (can be set temperature regime from +10 to 38 degrees)

Such a heating furnace can be made in two modifications - with a closed and open combustion chamber. Closed models of stoves are equipped with an additional chimney that removes combustion products, open stoves are models that look like a fireplace and have an open combustion chamber.

This heating stove is installed on the floor. What do the reviews say about convector models? For example, Vladislav's review from Astrakhan: “Tests have shown that this gas piece heats well, it feels like it is at the declared 4 kW power.

The thermostat is excellent - it allows you to maintain the temperature of the house up to +30 degrees, however, it smokes a little, I've been looking for the reason for a week, I think it's about the gas pressure ”. These gas ovens are also practical from a financial point of view - simple model with a power of 2 kW will cost from $ 55, but design heating stoves with an open combustion chamber buy for 50 cu will not work, since they can cost all $ 500.

3. Convection gas ovens - these heating devices are designed for summer cottages with an area of \u200b\u200bup to 350 square meters and work according to a simple principle. The lowest heat of combustion is used here, that is, the heating of the rooms of the house is due to the amount of heat that is formed during the complete combustion of the gas.

Convection appliances have several advantages:

• The minimum level of heat loss.
• A variety of modifications that allow you to choose a model for any summer cottage, be it 40 squares or 250.
• Availability of protection functions in case of an emergency.
• Possibility of automatic temperature control.

Convection models also have their drawback - most of the ovens have a low power up to 1000 W. True, the reviews of consumers of such stoves note the low power as an advantage - the device saves fuel.

Convection heating ovens are also convenient because they can be installed on the wall, thereby increasing the heating area of \u200b\u200bthe house. There are, of course, models that are installed on the floor or on a special platform, but such a convection oven is more industrial than “home”, since it has a capacity of several MW.

As for the price of appliances, convection heating models will cost more than other stoves. Their price starts from 310 USD. but the most expensive stove can be bought for $ 1,500. As a rule, the cost will directly depend on the additional functions and power of the furnace.

Five criteria for choosing a gas oven

To find a practical and economical model for heating a summer cottage, pay attention to several criteria:

And one more thing - with permanent residence in the country, it is best to buy convection models with additional safety features - the heating stove can automatically reduce the gas supply if the oxygen level is low or turn off the supply at a critical level of inclination of the device.

You have carefully studied the heating systems market, listened to the opinion of experts, got acquainted with the reviews and decided to install it at home gas heating furnaces... Then you should find out in more detail what these heating furnaces consist of.

The most important figure in a gas heating system is the heat generator, or, in other words, the boiler.

Boilers are divided into the following types:

• Single-circuit boilers;
• Double-circuit boilers.

Single-circuit boilers are used only for space heating, and double-circuit boilers are designed both for heating rooms and for heating water.

The elements of the boiler are a heat exchanger and gas burners for heating, they constantly interact with each other.

Gas burners are inflatable and atmospheric.

Atmospheric burners run exclusively on gas, while inflatable burners run on both gas and liquid fuel.

Gas heating furnaces may include a gas water heater for heating. It is needed to heat water. When purchasing it, pay attention to its power and the ability to control gas consumption, water flow, its method of gas ignition and a reducer to maintain a constant gas pressure.

In addition, gas heating furnaces include circulation pumps, a combustion control unit, blocking and protection systems, pressure and temperature sensors.

Gas heating furnaces are ignited using a pilot burner. Instructions for its use must be provided by the manufacturer.

Remember... if the burner does not ignite within the first five seconds, turn off the oven, ventilate the area and try again. If it fails again, contact your supplier.

Here you can order boilers produced by one of the leading European manufacturers of the Swedish concern STS. Annually the plant manufactures more than 20,000 boilers with a capacity of 10 to 200 kW, operating on liquid fuel, gas, electricity, coal and wood.

The gas oven is currently of particular interest. Let's make a reservation right away that further we do not mean gas hobs and hot water boilers; these are separate types of gaseous fuel heating devices. Also a special topic is technological gas furnaces for industrial purposes. We are interested, simply speaking, in household gas stoves.

The cost per unit of heat from natural gas is today much lower than from other sources, including electric heaters. In terms of the convenience of delivery and consumption, natural gas is second only to electricity, but it can be stored for future use and stored without fear of dampness, bituminization, spontaneous combustion, and other shortcomings of solid and liquid fuels. This situation will remain in the coming decades; in any case, for a time several times longer than the estimated service life of gas heating appliances. If you come up with a way to distribute heat to rooms without pipes, radiators and coolant, then gas heating will be not only economical during operation, but also requiring 1.2-2 times lower initial costs than traditional water heating. And this method is already known, see below.

We will also take a closer look at gas. A citizen of average and above average income in his apartment can afford a maximum mini-sauna, see fig. But they are produced mainly by electric ones, and the park costs a pretty penny. And to get permission for gas - as they say, do not be told by nightfall. Plus - the destruction of the apartment from construction and installation work.

In general, those who like to take a steam bath in their bath now do not go to it, but leave for the weekend. But firewood "from the forest, of course", alas, are in the past. In the vicinity of summer cottages, everything is selected cleanly. If only to scrape together for kebabs, and for a bathhouse of firewood you need several armfuls. Moreover, the time factor: the sauna is heated with wood until ready for at least 2-3 hours. Family sweating in shifts - 3-4 hours. You cannot fuss about steamed, otherwise the bath will only be harmful, this is another 2-3 hours of rest. How much is left for other chores and entertainment if you do not plan to spend the night? And if it is planned, then out of 2 days off, only 1 remains for household chores. What, in this case, does a gas sauna stove give? A lot:

• Kiln lighting - instant; about an hour is saved on just the fuel lift.
• Women and children can take a steam bath after 30-40 minutes after starting the oven (if it is of a special design for gas, see below), and 1.5-2 hours will be enough for the whole family; total gain in time - 3-4 hours, i.e. extra half a day on the farm.
• The price of gas for the bath is comparable to that of solid fuel, but which is more convenient to carry - a propane cylinder or a bag and a half of coal? The question is rhetorical.

What is often forgotten

Gaseous fuel has a remarkable property: the rate of its combustion can be arbitrarily high, up to detonation. They fight the danger of an explosion by adding a perfume to the household gas: the human nose literally smells mercaptan molecules, and the unbearable stench will force to take the necessary measures, according to physicists, many orders of magnitude before the concentration of gas in the air reaches a dangerous level.

In this case, something else is more important: with the correct design of the burner, the gas completely, up to CO2 and water vapor, burns out within a few centimeters from the burner nozzle at any value of its supply. As a result, firstly, in a gas bath stove, there is no need to fear clogging of the flowing (open) heater with soot and soot.

Secondly, a gas stove for heating a house is capable of maintaining maximum efficiency. up to 5% and even 3% of the nominal power; for stoves using solid and liquid fuels, with a decrease in power below 10-15% of the nominal, the efficiency drops sharply. Since in mid-latitudes during the heating season the heat loss of a building changes depending on the weather more than 10 times, the savings in the thermal equivalent of fuel is almost double.

Third, the risk of burnout drops sharply. Carbon monoxide, carbon monoxide, has no odor, and the first symptoms of poisoning appear even at a rather severe degree. Fragrance - mercaptan burns more difficult than saturated hydrocarbons, and if the fuel does not burn out, its smell will water your eyes long before the waste goes. A person can withstand a CO2 concentration of up to 2% by volume without harm to himself (in the atmosphere - 0.04%; in residential premises, up to 0.6% is permissible). These circumstances make it possible to organize gas mobile and temporary heating, for example. for giving, see below.

But why an oven?

Well, the reader might say, we already know about gas. Perhaps more of yours. But why should he - in the oven? Industry and utilities are already breathing natural gas.

Heating living quarters with individual stoves can be environmentally friendly. And the point is not only that up to 30% of heat is lost in the mains of the CHPP. Small emissions of combustion products, extended in time and distributed over a large area, nature manages to process before they harm. And of the same or even less magnitude, a burst emission from the pipes of the CHPP, also burning gas to CO2 and H2O, partially reaches the stratosphere and adds a greenhouse effect.

For comparison: during a summer thunderstorm in the Moscow region, energy is discharged up to 2 Mt of TNT equivalent. Within a few minutes, on an area of \u200b\u200babout 10 sq. km. And over Hiroshima it was blown up 20 times less, but instantly and at one point.

Buy or do?

The first thing to know when you are interested in gas ovens is self-made gas appliances by the Ministry of Emergency Situations are not certified; their operation is expressly prohibited. At the same time, buy a good gas stove for constant heating of 1 room up to 120 sq. m of domestic production is possible for an amount equivalent to $ 800-950. "Firm" will cost 50-150 USD more, but this is money "for a star", the quality of Russian gas appliances is recognized throughout the world.

A mobile gas heater with a capacity of up to 12-15 kW costs up to 350 USD; you can find a good certified one for 150 USD. Separate heating elements (more details below) for 8 sq. m of constantly heated area costs about 100 USD, i.e. a medium-sized home heating system will cost less than USD 1,000, including installation of pipelines and fittings. This is several times, just like that, it is cheaper to build a conventional furnace, and no complex construction work is required in the building; pipelines can be laid under a false ceiling.

Can you do this work yourself? No, only certified specialists are allowed to work with gas. The contractor company itself will draw up all the documents for gas heating. It will cost, together with work, about 600 USD, which is still much cheaper than building a Swede that heats 1-2 rooms.

You can gasify an existing stove with your own hands by purchasing a special stove burner for it (see fig.) For 200-250 USD (in rubles). Such burners are equipped with automatic devices that shut off the gas when the flame goes out, the furnace and the ambient air overheat, gas leaks, etc. More expensive models are supplied with auto-ignition.

Note: only forced draft burners are suitable for domestic ovens! Naturally aspirated burners are intended for other purposes. Their use in household ovens is unacceptable!

Gas stove burners are supplied with a certificate of suitability (do not forget to ask the seller!) And are sold as separate appliances. They are installed in the opening (created) of the furnace and do not require alteration of the furnace. Thus, a gas-wood stove is obtained.

Which oven is suitable for gas?

Natural gas, as already mentioned, burns very quickly and emits a lot of heat. Brickwork is simply not able to immediately perceive and transmit such a flow to the room; a gas burner is an instantaneous device, and a brick oven is a heat accumulator. Therefore, they are uniquely suitable for gasification only, their efficiency on gas increases. If you do if you want to gasify your grandfather's stove, then a brick gas stove must meet the following conditions:

1. Not to have an extensive furnace section and massive masonry - no longer.
2. The stove must be made according to the channel scheme with a developed system of smoke circulation, or.
3. All heat generation must take place in the firebox, i.e. all without exception disappear: natural gas is too energetic for them, the exhaust gases from under the dome of the bell will be forced into the chimney, without having time to give off heat to the furnace body.

In any case, the acceleration of a brick oven on gas requires a very long time, 4-6 days. During this period, the gas supply is gradually increased from the minimum to the nominal. Hence the consequence: it makes sense to gasify a brick oven only if it will be fired continuously for a long time. But what kind of masonry is needed that can withstand a constantly large, over 450 kW / cu. m, thermal stress?

Note: nevertheless, traditional stove-makers do not abandon attempts to develop brick ovens under gas. There is a sense in these searches - it breathes, which creates a healthy microclimate in the room. Of the successful samples, one can note the AKKh-14 heating and cooking furnace designed by Yu. P. Sosnin; its advantages are confirmed by operating experience; more than 10,000 copies are in operation in the Russian Federation. But still the cost and weight of its "brick" plus additional construction works - a foundation for the oven is needed.

What do you need besides money

First of all, you need to check if the certificate for the burner is valid. The easiest way to do this is to make a copy of it and show it to the inspector of the gas service. He can advise in advance which model is better to take. The burner power for a bath stove is calculated based on the value of 1.5 kW per 1 cu. m for warming up the steam room to 80 degrees (where did the 252 kcal / 0.4 cubic meter walking in Runet come from? To count it was inconvenient, or what?); for household - according to the heat engineering calculation of the building, or it is taken equal to the power of the existing furnace.

Note: no need to fight too much with the heat loss of the bath, turning the steam room into a thermos. A proper, healthy bath must breathe.

Next, you need to check your stove: the opening of the firebox must be with a metal frame. Dimensions of the opening itself - height within 470-550 mm, width 350-450 mm; together with an overlay, respectively, 615-680 mm and 515-665 mm. Then - the room. Installation of a gas oven is allowed in rooms with a volume of at least 8 cubic meters. m with a ceiling height of at least 2.2 m.In a room with a stove, there must be an opening window with a width of at least 60 cm, an area of \u200b\u200b0.6 sq. m, and a gap under the door of at least 40 mm for air flow. Instead of a gap on the door, there may be a ventilation grill. Distance from the stove to the nearest wall made of combustible material - from 500 mm. Removal of the refractory base of the furnace - from 100 mm in any direction.

For the bath, an additional condition applies: the door of the firebox must not go out into the washing or steam room. Therefore, she created the fireboxes of gas bath stoves (see below) are made elongated so that the door goes into the dressing room. So keep in mind, it's better not to think about gasifying a stove with a stove standing right in the steam room. A typical installation diagram of a gas bath oven is shown in Fig. it is also suitable for other cases, only it is no longer necessary to bring the firebox to the next room. For more information about the bath device, see the video below; everything shown there also applies to gasified baths.

Video: bath device

Note: supercharging with automatic require power supply. Therefore, in regions with an unstable power supply, it is not worthwhile to close the gas burner into the furnace tightly so that it can be heated with wood / coal if necessary.

After installing a burner, or a new furnace, a gas inspector is called for inspection; if necessary, eliminate the noticed shortcomings. Next, the oven is connected to the gas main; this should be done by specialists. When the burner is powered from the cylinder, you can attach it yourself using the supplied burner (do not forget to check!) Hose and reducer and present everything for inspection at once. Then - walking through the authorities with papers, the description of which is a separate topic; ends with the issuance of a permit to operate the furnace.

Note: a hose with a reducer and other fittings can be bought separately, but obtaining a permit is greatly complicated, because Requires certificates for each separately purchased node.

When no papers are needed

Homemade gas stoves, without caring at their own peril and risk of permits, are often used by home craftsmen for technological purposes in non-residential premises. The gas makes it possible to obtain a chemically neutral flame with a temperature, when pressurized, up to 1600 degrees. Craftsmen-jewelers use microburners made of medical needles of different diameters, pressurized from an aquarium compressor. In any case, the room in which the furnace / burner is operated must be equipped with ventilation that provides at least 2 full changes of air volume per hour.

To end the baths

Among the household stoves on sale, gas baths are perhaps the most popular product, so you need to add something about them. Namely: gas sauna stove is uniquely suitable for a sauna with completely dry steam; steaming in a bathhouse with such a stove in Russian, with a birch broom and adding kvass is difficult.

The reason is the same too fast gas combustion. A gas burner, without blazing into the chimney in vain, is able to "burn" the stove properly at the rate of 6 kg of river pebbles per 1 cubic meter. m steam room, and for a vigorous Russian steam you need at least twice as much stone. Experienced manufacturers (Termofor, Tulikiivi, for example) find a compromise, firstly, by offering to buy a stove made of stones that combine high heat capacity with high thermal conductivity, for example. steatite and other rocks from the group of talcochlorites. The surcharge, however, requires a considerable amount.

Secondly, this is already a domestic notion, a double stove is made: the main large heat-storage closed and smaller open specially for feeding; a diagram of a gas oven with a double heater and its appearance are shown in Fig. The configuration of the convector (it is needed to speed up the heating of the bath), the size and location of the holes in it are accurately calculated.

You can put it into such a stove made of an ordinary stone about once every half an hour, and only with water. Restrictions are also imposed on the broom: only birch and only dried. Pouring kvass and steaming with a freshly cut birch broom turns out to be difficult even for a strong, non-drinking man, and with an oak broom, it is probably better not to experiment even with heroes.

The second possible option is to gasify the basket heater like Vesuvius, see fig. on right. However, the heating time of the bath will remain "wood-burning", and the gas supply, so that the heat does not fly away into the pipe in vain, will need to be gradually and gradually increased from a minimum to about 0.7 of the nominal value within 1-1.5 hours. And the most important thing: basket sauna stoves are not available with an elongated firebox, i.e. according to safety rules, gasification is not subject, because the door of the firebox with the base of the burner cannot be brought into the dressing room.

Which oven is best?

So, since we are talking about gas, you still need to buy a stove. Then, naturally, we need a better gas oven. How to choose it? Popular rumor, that is, consumer ratings, is essentially true, but it would be strange if advertisers did not gradually try to use such a powerful tool for promoting goods in the interests of their customers. In addition, a quiet, imperceptible, but far-reaching revolution has recently taken place in the gas-furnace business. We will talk about it below, but for now we will discuss how to choose a better oven yourself, regardless of the principle of its operation.

amount

In this case, this term refers to the efficiency of the oven. To calculate it, in addition to your own initial data, you need to know the gross calorific value of the fuel, or its heat of combustion. For combustible gases used in everyday life, it is as follows:

• Natural gas in the Russian Federation - 34-38 MJ / cu. m; average - 36 MJ / cu. m.
• Pure methane - 34.67 MJ / cubic meter m.
• Pure liquefied propane (density 0.51 kg / l) - 25.54 MJ / cu. m
• The same, butane, density 0.58 kg / l - 28.61 kg / l.
• Summer propane-butane mixture (50% / 50%), density 0.545 kg / l - 27.09 MJ / kg.
• The same, winter, 90% propane and 10% butane, density 0.517 kg / l - 25.85 MJ / kg.

Note: those who want to determine the heat of combustion of gas from their pipe by measuring the boiling time of a kettle, etc. you should know that the efficiency of the kitchen gas stove does not exceed 65% And what exactly will this particular stove in this particular kitchen with this particular vessel with this particular water on this particular burner for this particular atmospheric pressure - is known specifically only to the local specific Barabashka, and to no one else.

Now let's decide on the consumption of heat and fuel. Take, for example, a summer cottage with a 12 cubic meter steam room for two. m (2x3 m in plan and with a ceiling height of 2 m). It will need 1.5 kW x 12 cubic meters. m \u003d 18 kW of heat, or 18 kJ / s of heat flow from the furnace. Per hour - 18 kJ x 3600 s \u003d 64.8 MJ of heat. Further, we consider that our bath is gasified. Then, for an hour of bathing procedures at 80 degrees, it will take 64.8 / 36 \u003d 1.8 cubic meters. m of gas.

Here it is necessary to take into account the fact that the manufacturers of furnaces give gas consumption in them on the basis of heating the steam room to 60 degrees; Doctors say that at higher temperatures, women and children and at least something slightly sick (including temporary malaise after yesterday's and euphoria from recent libations) is dangerous to steam. The heat loss of a room generally depends on the difference in temperatures inside and outside according to a power law, but since temperatures are measured from absolute zero (-273.16 degrees Celsius), then within 80-60 Celsius it can be replaced with a linear one without noticeable error.

So, at 60 degrees and the furnace efficiency in 100% gas, 60/80 \u003d 0.75 x 1.8 cubic meters will be needed. m \u003d 1.35 cubes. The choice of the stove is generally simple: the closer the fuel consumption declared by the manufacturer to this value, the better the stove. You just need to remember to look in the specification for what volume of the steam room it is declared for, and bring it to 12 cubes. If less than 1.35 cubic meters of gas is declared for 12 cubic meters of a steam room, then he is a swindler. Or he invented a perpetual motion machine, but he himself does not know about it.

Now let's check it independently, according to popular rumor. For example, in the Russian Federation, the Termofor Urengoy oven is on the 1st place with a decent margin from the rest. Perhaps because of the price of only 12,000 rubles? We look at the declared gas consumption for 12 cubic meters of the steam room - 1.71 cubic meters. m / hour. We consider the efficiency of Urengoy: 1.35 (theoretically ideal flow rate) / 1.71 (real for this furnace) \u003d 0.79 or 79% Very good and very similar to the truth indicator; probably worth taking.

Roughly offhand

compact infrared gas heater

As for infrared gas heaters, which will be discussed below, their market with a culture of use has not yet developed properly, but a single methodology determination of efficiency not yet developed. These devices, in contrast to the bath stoves, are of long-term continuous use, so you need to somehow take into account the cost of heating and its reliability. Therefore, you can choose more or less definitely only by comparison.

First, without caring about dimensions and any other physics, we multiply the "consumption" parameters: the hourly gas consumption declared in the specification by the cost of the device. Let's get a certain carelessly abstract value A. Then we multiply the "economical" indicators: heat power by the duration of the brand guarantee in months; we get a similar value B.

Further, too, nothing complicated: C \u003d B / A. The more C, the cheaper the heating costs. For comparison of various models, this is enough, and you can calculate the exact cost of heating, knowing the amount of heat demand, the heat of combustion of the available gas and its consumption according to the specification for the selected sample.

Quality

It remains to understand such consumer parameters as reliability and functionality. Here the only possible way is to compare the word of mouth with the rating of sales. By sauna stoves in Russia, the already mentioned domestic Termofor and Finnish Tulikivi are in the lead; for infrared heaters of constant action - also domestic Bi Car and American Master. Recently, the Russian-Chinese Comfort has cut through quite well. They speak well of him, but they have not been on the market for long. Therefore, after looking at the Comfort gas oven, it is advisable to consult with real users.

Gas-fired revolution

This revolution is associated with the advent of gas infrared emitters, or infrared burners; both are designated by the abbreviation GII. There is a difference between them; which one - see below. For now, it is worth noting the fact: in terms of a set of parameters, including price ones, GII overtakes conventional heating stoves, like Porsche - the pre-war emka. For example, a GII with a capacity of 1.5 kW heats an area up to 12 square meters. m, itself weighs about 7 kg, and costs up to 5000 rubles. We emphasize: this is not an analogue of an electric fireplace, we are talking about constant heating of living quarters. The price of a gigacalorie of heat turns out to be 1.5-2 times lower than from any other source. In addition, GII-based household gas stoves are significantly better than other heating devices in terms of sanitary and hygienic indicators.

How is this achieved? Due to the distribution of heat, similar to a warm floor, see fig. The comfort zone turns out to be where people are, and the heat loss through the ceiling sharply decreases, which is especially noticeable in one-story houses. Plus, the floor can be insulated from the inside; the flow of heat from above will not let the dew point into the room. But, unlike underfloor heating, complex construction work is not needed, there is no thin winding tube walled into the floor that can clog or leak (but how to repair it without breaking the floor?) Unlike electric heating, it is not expensive electricity that heats, but gas, a unit of energy which is several times cheaper. Another plus - the flow of warm air from the heated IR floor is uniform over the area of \u200b\u200bthe room; the inhabitants live, as it were, on a warm island with an even climate.

GII device

GII burners are open type devices. In them, the gas-air mixture is blown through narrow channels in micro doses; air is sucked in naturally without pressurization. In ceramic GII (diagram in Fig. Yb; t), the nozzle channels are made in a ceramic (most often carbon) plate, which itself heats up to 900 degrees. Thanks to high temperature in combustion microchambers, the efficiency of the device exceeds 90%, and 70-75% of the gas energy is converted into infrared radiation.

In catalytic GII burners, the combustible mixture passes through the catalyst mesh. The actual combustion catalyst is either platinum sputtering (eternal, but expensive), or nickel plating with additives (cheaper, but gradually burns out). Anyone who has used a windproof gas lighter is familiar with catalytic combustion.

Ceramic GII is cheaper than catalytic, but their power is limited to 12-15 kW, because it is difficult to make the mixture flow through narrow nozzles very intense. The dimensions of the ceramic GII cannot be very small; a rather large plate area is required for effective radiation. Catalytic GII for power up to 30 kW and more weigh several kg; they can be made miniaturized but are expensive.

Open GII in residential premises are limitedly applicable, because emit carbon dioxide, albeit in small quantities. In practice, in the presence of supply and exhaust ventilation for 2 air changes per hour, open GII for a power of up to 12 kW can be used for temporary heating under constant supervision.

GII emitters, or gas heating elements (diagram in the figure) are devoid of this drawback, therefore they can be used for constant heating of residential premises. They require pressurization, therefore they are volatile, but, on the other hand, any modern hot water boiler on gas is also volatile. And one and a half hundred years ago, pipelines for gas lighting were stretched by a cobweb across houses, and there was nothing, there was no general emergency, although the gasification technique was then compared with the current cave. Also, gas heating elements require a gas duct, but typical ones in new buildings are quite suitable: exhaust gases (it is already difficult to call them flue gases) nothing at all, and their temperature is up to 400 degrees.

Purpose and evolution

The first on sale were open ceramic GII for temporary heating of garages and outbuildings, pos. 1 in fig. Probably, it was the need to create a dome of comfort in a room with large own heat losses, without burning exorbitant amounts of fuel, that prompted the creators of the first GII to develop them. GII for the garage is successfully used to this day: sellers offer them in a wide range, and prices for 7 years fell from 800 to 90-150 USD; certification and a separate permit for the operation of garage GII is not required. In everyday life, ceramic GII also found application to replace electric fireplaces, pos. 2, but this is just a mechanical transfer of a principle capable of much more.

GII as powerful, relatively inexpensive, reliable and non-volatile heat sources immediately attracted the attention of participants in field and expeditionary operations, hunters, fishermen, tourists, yachtsmen and others who faced the problem of heating away from civilization. But these categories of users required a higher power density in relation to mass and dimensions, so they preferred GII catalytic.

The first samples (pos. 3) resembled their non-catalytic counterparts. In the end, the "suburban" branch of the GII evolution spawned a gas mini-oven (picture on the right), which you can carry around on foot. However, there are not many of them on sale: the roads themselves, from 200 USD, and expensive gas for lighters is required for refueling.

The development of GII in the direction of constant heating turned out to be much more productive. The high specific, now per unit of radiating surface, power of the GII made it possible to organize warm islands directly under the open sky, for this it was only necessary to assemble the radiating panels under the umbrella-reflector and put it on the rack, pos. 4.

The efficiency and economy of heating by GII-"umbrellas" turned out to be so high that the question arose of using them for permanent heating of housing. At this time, the warm floors were wide open; their sanitary and hygienic properties were not in doubt, but the issue of the complexity of installation in existing buildings and maintainability arose. You already know the solution: the GII burners were replaced with gas heating elements, and the umbrellas were removed from the racks and hung directly from the ceiling. Here a large reflector is not really needed, and ceiling GII emitters are often made in the form of flat panels; in multi-storey buildings on floors below the topmost, the overall efficiency does not noticeably deteriorate from this.

Gas in cooking

The next area where gasification of stoves is not only useful, but absolutely necessary is the culinary and technological equipment. Gas baking oven, for example, occupying only about 10 sq. m of ordinary, non-production, area and does not require an industrial gas supply with electricity, allows you to bake up to 100-200 loaves of bread at a time, see fig. Individual bakers take full advantage of this circumstance, and those who are really good at baking bread do a good business at home with always secured demand.

The second culinary device, where the gas turned out to be more than appropriate, is this. Already a household tabletop (left position in the figure on the right) produces a product that even an unpretentious eater immediately distinguishes for the better from the one baked by an electric grill. In this case, the role is played by a large in comparison with the electric density of the heat flux created by the gas.

A completely unexpected result was provided by gasification of a traditional Pompeian pizza oven, right pos. Inveterate gourmets do not taste real noble pizza from a wood-fired or gasified Pompeian oven. But the productivity of the unit (and the income of restaurateurs) has grown by almost half. In this case, the high energy intensity and gas combustion rate provide an accelerated and more uniform heating of the furnace roof in time, which increases its productivity.

Workshop gas

The high achievable temperature and the absence of chemically aggressive substances in the combustion products make the gas flame very attractive for home craftsmen. You don't need much here: a heating furnace for heating small metal parts is obtained from ... empty tin can, see fig. Don't forget to just leave an air gap at the bottom!

Small-sized and gas-fired melting furnaces, incl. tabletop are also commercially available. But a home-builder or a homeworker IP will have to be disappointed here: the fire brigade and gas service do not issue permits for their operation to individuals. And legal entities - only provided with a production area, equipped accordingly. So in unsuitable rooms, you will have to make do with electric ovens.

About gas fireplaces

The remarkable properties of natural gas have spawned attempts to make a gas fireplace. However, it is impossible to recognize them as successful: the blue light is beautiful in its own way, but it is still not a living flame. Manufacturers, wise with burners, sometimes create something similar to him supposedly in a modern style, see the pic on the right. However, the psychological and aesthetic value of the fireplace traces its ancestry back to the well-fed primitive tribe after a successful hunt in a cave by the fire, and without chaotically dancing tongues of fire, a fireplace is not a fireplace. It's like putting a mast with a mainsail and a staysail on a Predator with a 400-horsepower Mercruiser. It will float, since it keeps on the water, but there will be no romance of sailing.

In a country house or a full-fledged private one, if you do not live in it all year round or there are no central heating pipes nearby to connect a building to them, then installing a compact gas heater - suitable option... It will come in handy during the cold season from time to time. Cool weather also happens in summer. Gas summer cottages come in handy when you need to dry the room. It is too laborious to start building a full-fledged heating circuit if the house is small. , powered by a cylinder, easily moving from place to place, is much better suited for such conditions. More often, units operating on natural gas are purchased as a portable heat source.

The basic equipment of the average of the body, burner, heat exchanger, heating element and gas cylinder. In addition, the heater is equipped with a thermostat and an automated gas shut-off mechanism.

Buyers choose gas heaters for a low price, compactness, clear operating principle and good efficiency. There are the following types of gas heaters:

1. Gas catalytic heater
2. Infrared device

Heating devices are divided into outdoor and indoor devices.

Italian gas convector for summer cottages

This type of heater resembles a typical battery, it is also placed under the window opening. Natural gas convectors use both gas from a gas pipeline and a liquefied version as fuel. The gas burns in an insulated container, heating the air that separates the chamber from the body of the apparatus. The convector heats up a small room in a matter of minutes, which is convenient if the country house is visited in cool weather, and there is a need to quickly warm up the room. The convector independently maintains the required temperature regime. When the required heating temperature is reached, the combustion becomes less intense. If the fire is extinguished, the protective system is triggered and the device shuts down.

Catalytic gas heater

This type of device is powered by gas or petrol. It can be used to heat a room of any size: from a small hut to a large warehouse. Heat is generated by a catalytic combustion process. It is distinguished by the absence of flames and any sounds, but at the same time by the active release of a large amount of heat. Heat is generated due to the oxidation of fuel trapped on the surface of the panel. The catalyst, which is part of the surface material, provokes oxidation. All processes take place on the solid surface of the panel without flowing into gaseous forms.

Such devices are safe, not subject to spontaneous combustion, do not pollute the environment

The heating element of the catalytic heater is a catalytic panel made of fiberglass with the addition of platinum. At the moment, instead of platinum, more topical catalysts are used, which promote deep oxidation and not. Some models are equipped with a fan heater in order to increase power. A gas heater can quickly heat up the air in a room.

In terms of their characteristics, catalytic devices are close to infrared heating devices. They are inferior to them in the speed of warming up the room, but they are silent.

Infrared model with thermostat and ceramic burner: from the cylinder and the line

Infrared or gas powered. Models with an infrared ceramic gas burner differ from other infrared devices by the presence of an open flame during operation. Such devices serve for a long time and heat effectively, in a short time evenly filling the entire room with heat. Despite such attractive characteristics, the gas ceramic heater is not the most popular. The reason is the high price. But the burner is worth it: it is independent of electricity, does not dry the air in the room, and is easy to install.

The infrared device is suitable for heating large-scale premises: hangars, hypermarkets. There is a wide range of devices on the market with various configurations and mounts. It is not difficult to find an infrared ceramic gas heater that fits perfectly into the interior and meets all technical requirements.
