Gas stove for giving with a cylinder. Is it worth it to use a gas heater in the country, which model to choose Household stoves for cooking gas

Heating a private house is one of the main concerns for the owner. When choosing a heater, the owner puts forward the requirements of practicality, duration and ease of operation, and the price 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 design includes gas pipelines for fuel supply, heat transfer, shut-off and control valves, and automatic equipment for safe fuel consumption.

Mains 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 furnace:

1. Operation at any time of the year, day. The gas heating stove in the house does not give interruptions, it is only important to take care of the presence of the coolant itself.
2. Increased efficiency. Devices provide a comfortable temperature in the house in any climatic conditions, including during severe winter frosts.
3. Convenience. Unlike solid fuel boilers, gas-fired units do not require a lot of space, raw materials are relatively cheap, and you do not have to equip a separate room for its storage.
4. Ease of operation. With a properly designed control system, all work comes down to pressing a button that starts the equipment in operation. Prevention and maintenance costs are kept to a minimum.
5. Durability. The gas stove for the home is one of the longest-running 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 in type of fuel, heat capacity, shape and other indicators. The equipment consists of several elements: body, chimney, foundation. In the case 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 fuel supply is considered more practical, in this case you don’t have to freeze if you forgot the cylinder or didn’t have time to fill it. For regions with interruptions in gas supply, experts recommend choosing combined devices that operate on all types of fuel: solid, liquid. Technology is more expensive, but positive properties quickly recoup the price of the units.

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

Heat capacity of the furnace

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

You should choose furnaces for their intended purpose, that is, for continuous or periodic operation:

1. Furnaces with a regular heating cycle are made of metal with thin walls, and are not capable of accumulating energy. The advantage is fast and uniform heating of the room. Minus - consumption of a large amount of fuel. But it is 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 stove would be more appropriate than all other units.
2. Periodic switching devices look like stationary ovens lined with brick or heat-shielding reflective screens. The design works on automation, switching on occurs when the set temperature level in the room decreases, and as soon as the air warms up to the desired parameter, the stove turns off.

Production material

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

There are several types of equipment:

• Pig-iron gas furnace for heating with a door of a furnace compartment. The door can be made of refractory glass, the firebox itself can be used to supply coal and firewood. The price of the device is high, the payback is fast, 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 the relatively low cost. The only downside is the low heat capacity.

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

Types of ovens by purpose

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

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 in the house depends on this parameter. The burner power, heated area, number of windows, doors, wall thickness, roof integrity are taken into account.
2. Equipment. Manufacturers equip the systems with adapters, which allows you to connect the unit to several fuel sources. But this design is suitable for houses no more than 2 floors high, otherwise the efficiency of the system drops.
3. Heat generation method. Furnaces with burners show greater performance 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 of the power supply, with automatic switching on and off of the device. A 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 work in a reduced mode, saving fuel. Burner with continuously adjustable it is expensive, but it allows you to quickly change the mode of heat supply.
5. Air supply to the furnace. Atmospheric ventilation of the combustion chamber differs, in which air is supplied in natural mode, the efficiency is 90%. And there may be an inflatable system where air is forced in, with an efficiency of 95%.
6. Type of fuel combustion chamber. A gas stove with an open combustion chamber takes air from the room, but the exhaust gases also exit into the room. Furnaces are mobile, convenient, 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 residences.

If the gas stove in the house is equipped additional sensor, which detects the level of carbon dioxide, the device will automatically turn off when a 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 buying, you need to request documents for the device, carefully read the instructions from the manufacturer.

Calculate gas consumption

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

Now you should calculate: the production of 1 kW of power requires 0.112 m3 of gas. That is, for heating 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 on the required amount of fuel per day, the heating season. From the given example: 13.44 m3 of gas is required per day, 403 m3 of gas is required 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 power of at least 12 kW should be installed.

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

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

Gas stove for 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 in place? And is it really contraindicated for another?

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

After all, it won’t 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 restrictions?

1. The furnace part should not be too large, but also the torch from the burner must not touch the furnace material.
2. The stove is not suitable without a smoke circulation system. Good scheme Dutch or Swedish stoves.
3. Bell-type stoves too not an option to switch to gas, because the product of gas combustion under the cap will not be kept, it will be carried out into the chimney, and the task of the cap is to have time to pick up heat. In this case, it won't.

Least Suitable for Russian bath will unshielded. But with a solid brick - also a perfectly acceptable option.

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

Gas as a fuel behaves quite controllably and predictably if do not violate the operating instructions. Therefore, you can get the given conditions without surprises.

For a better understanding, let's look at this:

Gas oven device

The above already, as it were, hinted at the fact that a gas stove is not much different from a wood stove. And indeed: if desired, you can modify the existing wood stove by putting a gas burner in it.

For your information! There are limitations, for example, it is better to set microflare burner so that the metal does not burn out, it is necessary to ensure 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 in the case when the gas is completely burned in the air, problems remain. After all all the heat goes up, and the lower part is not heated. Therefore, the steam room heats up unevenly, and therefore longer.

By the way, the dimensions of the fuel compartment in the initially gas stove will still be smaller than in the wood stove, but this is understandable - the firewood is voluminous, so additional space in the furnace was allocated for them. Gas doesn't need that much space. He only needs air.

IMPORTANT! And here is the really important point: for complete combustion, the gas needs an influx 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

To date, there are two types of burners:

• atmospheric;
• supercharged.

atmospheric

Cheap gas burner, because it is arranged quite simply. It is a tube or tubes through which one or another natural gas flows under pressure. Before it burns, it must mix with air, and air in this type of burners is supplied solely by means of draft. And if there is no well-conducted ventilation, then it is better not to experiment with such burners.

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

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

supercharged

The second type differs significantly from the first in design. The meaning of the difference is that make the pull even. To do this, you need a fan, and therefore electricity.

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

It is worth mentioning the advantages and disadvantages blast or fan(Yes, these are also options that are structurally 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 fan of the gas oven 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, it’s worth estimating how quickly the choice will pay off, because the pressurized burner has a big advantage: it is twice (!) More economical than atmospheric.

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

One more advantage worth mentioning: the possibility power settings.

work pressurized burners from both main gas and liquefied. At the same time, the transition from one type to another is quite simple.

Video

For a better idea of ​​the subject, watch the video, which clearly demonstrates the operation of a forced draft 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 species ovens.

Comparison of gas, wood and electric oven

Disadvantages of gas

1. Gas stoves are not only a fire hazard, but also an explosion hazard. Therefore it the only type of stove that requires a permit.
2. Since a gas stove can be either metal or brick, the issue is decided solely depending on the weight of the entire structure, including the chimney.
3. If the stove is metal, it will burn out sooner or later - with wood or gas. However, since gas it will happen faster.
4. According to requirements fire safety storage for gas cylinders should be a separate building.
5. Permission 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. While the maximum efficiency is maintained even if the power is reduced to 3-5% of the nominal. Wood-burners cannot boast of anything like that.
2. Exactly set temperature- a plus that electric ones also have, but is missing from.
3. Reduced preparation time baths - after forty minutes it is already possible to run children and women, and after a couple of hours the steam room goes “on mode” (! About steam room stoves).
4. Compared to wood burning: practical no soot and soot, No preparatory work with fuel, higher efficiency of the furnace.
5. Compared to electric: gas cheaper electricity.

Disadvantages of wood

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

Advantages of wood

1. is 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 appreciate a wood-burning brick or brick-lined stove as a source of uniform, soft heat, while inside the stove they heat up to 400 degrees to give light steam.
2. Those who are more interested in “just washing up”, of course, do not see the point in studying the intricacies of the art of a stoker and bathhouse attendant, but they are also able to evaluate a wood-burning stove as the least expensive both in purchasing it and in supplying it with fuel.

Disadvantages of electrical

1. Of course, you don’t need to get permission for an electric one, like 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. You may need to change the wiring to a thicker cable.
3. The cost of electricity is the highest among other types of fuel.
4. A rare one is either an expensive "thermos" or a Russian invention with a steam generator hidden in an open heater.
5. You can not pour a lot of water and wet the heating elements.
6. Heaters generally fail easily.

Advantages of electrical

1. Ideal.
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 look at what you need to focus on when choosing it.

Gas heater for sauna: which one to choose?

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

Power

Powerful gas oven for very large saunas

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

• nominal;
• minimum;
• maximum.

The last two define the boundaries of the stable operation of the burner while maintaining its safety. 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 incomplete combustion of the fuel, which should remain within the prescribed limits.

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

• 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 multiplying factor for the entire volume is 1.5;
• if , add another one and a half cubic meters to the calculated figure.

Let's summarize what we got. The final figure is the number of kilowatts needed to heat our premises. It remains only to compare with the 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 power of 10 kW, it 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 cheaper ones. atmospheric can only be placed in rooms 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 left to breathe).

Attention! The smaller the volume of the steam room, the more correct to take supercharged burner. Moreover, it is more suitable different types existing stoves (if you convert wood 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 also 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 on diesel fuel. If anyone has gas problems, 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's better if it's intended. Their difference is that they are longer than the usual ones. 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 should be heated exclusively from the dressing room!

Automation

Automation in a gas oven is designed not only to simplify its management, but also ensure people's safety located in the room (not to mention the safety of the room itself). That's why it should not be neglected.

What automation can be purchased for which burners?

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

Useful video

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

IN supercharged more automatic burners: she answers for shutting off gas in cases of lowering its pressure in the network, power outage or flame extinction.

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

Nuances to consider before installing a gas stove

We didn't touch the topic. self-manufacturing gas oven for one simple reason:

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

The only thing in your power is buy a ready-made burner And prepare the stove for gasification. Compliance with the following standards should be checked:

• the firebox must (!) Go out 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 ​​0.6 sq. meters, slots under 4 cm or ventilation grilles;
• the refractory material under the stove must be at least 10 cm wider than the dimensions of the stove on each side;
• combustible walls should not be closer than half a meter to the heater.

IMPORTANT! All work related to gasification is carried out professionals.

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

fire certificate for gas stove

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

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

When the equipment is installed but not yet connected, you need to call the inspector for inspection. He must check everything and, if necessary, point out 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 to operate the stove, which is issued by Rostekhnadzor.

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

The most famous Russian companies producing gas furnaces

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

"Teplodar"

"Termofor"

***
Well, if you are not afraid of the hassle of paperwork, a gas stove can really save a lot of labor and money (this will be later, but at first you will have to spend a lot of money). But do not forget about the main thing - about security, because today we have all the means to prevent the explosion of domestic gas.

Where can I 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

Each factor plays a big role. Therefore, the correspondence of the parts of the installation is important to plan carefully. The heating system includes thermostats, a connection system, air vents, manifolds, batteries, fasteners, an 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.

Each owner of a summer residence with the onset of cold weather decides on the organization of the heating process. And the owner of the dacha solves several important tasks - this is a matter of safety, economy, personal taste and, of course, common sense.

After all, most heating systems cost a lot of money, and the cottage does not always need constant heating. Best Choice will become a practical gas stove for a summer residence. 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 heat up 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 the house to choose will depend on the characteristics of each type.

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

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

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

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

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

By the way, it is gas burners that are used for heating baths, as this fuel is more economical than firewood and electricity, and more convenient to use - it is enough to set fire to the burner and you can enter the bath in an hour. To receive bath procedures, a gas burner of 2000 W will be enough.

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

Burners are suitable only for a quick bath treatment. You can buy burners for a bath for 100 USD. 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 convector oven

Such a heating model is popular with cottage owners due to its rational power and mobility. It is these two parameters that mark all reviews of convector models. Convectors can work 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
• Efficient heating up to 80 sq. meters
• The presence of a thermostat that regulates the intensity of gas supply depending on the set temperature level (you can 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.

Such a heating stove is installed on the floor. What do reviews say about convector models? For example, a review by Vladislav from Astrakhan: “Tests have shown that this gas thing heats up well, according to the sensations - at the power declared at 4 kW.

The thermostat is excellent - it allows you to maintain the temperature at home up to +30 degrees, however, it smokes a little, I have been looking for the reason for a week now, I think it's 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 designer heating furnaces with an open combustion chamber, buy for 50 c.u. it will not work, since they can cost all 500 USD.

3. Convection gas ovens - these heating devices are designed for cottages with an area of ​​\u200b\u200bup to 350 squares and work on a simple principle. Here, the lower calorific value is used, that is, the heating of the rooms of the house occurs due to the amount of heat that is generated in the process of complete combustion of 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 dacha, whether it is 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 ovens have a low power of up to 1000 watts. True, consumer reviews of such furnaces note low power as an advantage - the device saves fuel.

Convection heating stoves are also convenient because they can be installed on the wall, due to which the heating area of ​​\u200b\u200bthe house increases. There are, of course, models that are installed on the floor or a special platform, but such a convection oven is more industrial than “home”, as 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 choose a practical and economical model for heating a summer house, pay attention to several criteria:

And one more thing - 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 the device's inclination.

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

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

Boilers are divided into the following types:

• Single-circuit boilers;
• Double boilers.

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

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 operate exclusively on gas, while inflatable burners operate on both gas and liquid fuels.

The composition of gas heating furnaces may include a geyser for heating. It is necessary for heating water. When purchasing it, pay attention to its power and ability to control gas consumption, water flow, its method of igniting gas and a reducer to maintain a constant gas pressure.

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

Gas heating stoves are ignited with 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 stove, ventilate the room and try again. If it fails again, contact your supplier.

Here you can order boilers manufactured 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 furnace is currently of particular interest. Let us make a reservation right away that further we do not mean gas cooking stoves and hot water boilers; These are separate types of heat engineering devices on gaseous fuel. Also a special topic - technological gas furnaces industrial purpose. We are interested, simply put, in household gas stoves.

The cost per unit of heat from natural gas is currently much lower than from other sources, including electric heaters. In terms of ease of delivery and use, 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 disadvantages of solid and liquid fuels. In the coming decades, this situation will continue; in any case, for a time several times longer than the estimated service life of gas heaters. If you come up with a way to distribute heat throughout the rooms without pipes, radiators and coolant, then gas heating will not only be economical during operation, but also require 1.2-2 times lower initial costs than traditional water. And this method is already known, see below.

We will also consider gas in more detail. A citizen of average and above average income in his apartment can afford a maximum mini-sauna, see fig. But they are produced mainly electric, the park flies a pretty penny. And to get permission for gas - as they say, not by night, be it said. Plus - the defeat in 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 go out for the weekend. But firewood "from the forest, of course", alas, is a thing of the past. In the vicinity of holiday villages, everything is picked up cleanly. At least scrape together for kebabs, but for a bathhouse of firewood you need a few armfuls. Moreover, the time factor: the sauna is heated with firewood until ready for at least 2-3 hours. Steam family in shifts - 3-4 hours. You can’t fuss about steamed, otherwise the bath will only do harm, it’s another 2-3 hours of rest. How much is left for other chores and entertainment if an overnight stay is not planned? And if it is planned, then out of 2 days off, only 1 remains for household chores. What does a bath gas stove give in this case? Quite a few:

• The kindling of the furnace is instant; about an hour is saved on a fuel tray alone.
• Women and children can steam already 30-40 minutes after starting the stove (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. an extra half day for housekeeping.
• Gas for a bathhouse costs comparable to solid fuel, and what is more convenient to carry - a propane tank or a bag and a half of coal? The question is rhetorical.

What is often forgotten

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

In this case, something else is more important: with the correct design of the burner, the gas completely, to CO2 and water vapor, burns out for several centimeters from the burner nozzle at any value of its supply. As a result, firstly, in a gas sauna stove, you can not be afraid of clogging the flowing (open) heater with soot and soot.

Secondly, a gas stove for heating a house is able to maintain maximum efficiency. up to 5% and even 3% of the nominal power; for solid and liquid fuel furnaces, when the power drops below 10-15% of the nominal value, the efficiency drops sharply. Since in the middle latitudes during the heating season, the heat loss of a building changes more than 10 times depending on the weather, the savings in the thermal equivalent of fuel are almost double.

Thirdly, the risk of burning decreases sharply. Carbon monoxide, carbon monoxide, has no smell, and the first symptoms of poisoning appear already 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 off. A person, without harm to himself, can withstand a concentration of CO2 up to 2% by volume (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 bake?

Well, the reader may say, we already know about gas. Perhaps more than yours. But why is it in the oven? Natural gas is widely used by industry and public utilities.

Heating residential premises with the help of individual stoves can be saving for the environment. And the point is not only that up to 30% of heat is lost in the CHP mains. Small emissions of combustion products, stretched over time and distributed over a large area, nature has time to process before they harm. And the same or even smaller burst emission from the pipes of thermal power plants, which also burn gas to CO2 and H2O, partially reaches the stratosphere and adds to the 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 ​​​​about 10 square meters. km. And over Hiroshima it was blown up 20 times less, but instantly and at one point.

Buy or do?

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

Mobile gas heater with a power of up to 12-15 kW costs up to 350 USD; you can find a good certified one for 150 USD. Separate heating elements (for more details - below) for 8 sq. m of permanently heated area cost about 100 USD, i.е. a heating system for a medium-sized house on them will cost less than 1000 USD, including the installation of pipelines and fittings. This is several times, just like that, cheaper than building a conventional furnace, and no complex construction work is required in the building; pipelines can be laid under a suspended ceiling.

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

With your own hands, you can gasify an existing stove by buying a special stove burner for it (see Fig.) for 200-250 USD (in rubles). Such burners are equipped with automation that shuts off the gas when the flame goes out, the furnace and ambient air overheat, gas leaks, etc. More expensive models are equipped with auto-ignition.

Note: only forced draft burners are suitable for domestic ovens! Atmospheric burners, without pressurization, are intended for other purposes. Their use in domestic ovens is unacceptable!

Furnace gas burners are supplied with a certificate of suitability (do not forget to ask the seller!) And go on sale as separate devices. They are installed in the opening (created) of the furnace and do not require alterations to the furnace. Thus, a gas-wood stove is obtained.

Which stove is suitable for gas?

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

1. Not to have an extensive furnace part and massive masonry - disappears.
2. The furnace must be made according to the channel scheme with a developed smoke circulation system, or.
3. All heat generation must take place in the furnace, i.e. all without exception disappear: natural gas is too energetic for them, the exhaust gases from under the dome of the hood will be forced into the chimney, not having time to give off heat to the body of the furnace.

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 value. Hence the corollary: it makes sense to gasify a brick oven only if it will be heated continuously for a long time. But what kind of masonry is needed that can withstand constantly large, over 450 kW / cu. m, thermal stress?

Note: nevertheless, traditionalist stove-makers do not give up trying 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 heating and cooking stove AKH-14 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- the foundation for the furnace 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 gas service inspector. He can also 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 cubic meter. m for warming up the steam room to 80 degrees (where did the 252 kcal / 0.4 cubic meters 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. Proper, healthy bath should breathe.

Next, you need to check your stove: the opening of the firebox should be with a metal frame. Dimensions of the opening itself - height within 470-550 mm, width 350-450 millimeters; together with the overlay, respectively, 615-680 mm and 515-665 mm. Then there is the room. Installation of a gas stove 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, with an area of ​​​​0.6 square meters. m, and a gap under the door of at least 40 mm for air flow. Instead of a gap on the door, maybe ventilation grille. The distance from the furnace to the nearest wall of combustible material is from 500 mm. Removal of the refractory base of the furnace - from 100 mm in any direction.

For a bath, an additional condition applies: the firebox door should not go into a washing or steam room. Therefore, the fire chambers of gas sauna 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 potbelly stove with a heater standing right in the steam room. A typical diagram of the installation of a bath gas furnace is shown in fig; it is also suitable for other cases, only it was no longer necessary to bring fireboxes into the next room. For more information about the bath device, see the video below; everything shown there applies to gasified baths.

Video: bath device

Note: pressurization with automatic require power supply. Therefore, in regions with unstable power supply, it is not necessary to close the gas burner tightly into the oven so that you can heat it with wood / coal if necessary.

After installing a burner, or a new furnace, a gas inspector is called in for inspection; if necessary, eliminate the observed deficiencies. Next, the furnace is connected to the gas main; this should be done by experts. When the burner is powered from a cylinder, you can connect it yourself using the included burner (do not forget to check!) Hose and reducer and present for verification all 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 much more complicated, because. certificates are required for each separately purchased node.

When Papers Are Not Needed

Home-made gas stoves, without worrying about permits at their own risk, are often used by home craftsmen for technological purposes in non-residential premises. Gas allows you to get a chemically neutral flame with a temperature, when supercharged, up to 1600 degrees. Craftsmen-jewelers use micro-burners from medical needles of different diameters, supercharged from an aquarium compressor. In any case, the room in which the oven/burner is operated must be ventilated to provide at least 2 complete air volume changes per hour.

To end the baths

Among household stoves for sale, gas baths are perhaps the most sought-after product, so you need to add something about them. Namely: a gas sauna stove is definitely suitable for a sauna with absolutely dry steam; it is difficult to steam in a bathhouse with such a Russian-style stove, with a birch broom and kvass.

The reason is the same too rapid combustion of gas. A gas burner, without blazing into the pipe in vain, is able to “burn” the heater properly at the rate of 6 kg of river pebble per 1 cubic meter. m of a 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. However, there is a large fee to be paid.

Secondly, this is already a domestic notion, the heater is made double: the main one is a large heat-storing closed one and a smaller open one especially for the extra; the diagram of a gas furnace 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.

It is possible to give such a heater from 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. Adding kvass and steaming with a freshly cut birch broom turns out to be hard even for a strong, non-drinking peasant, and it’s probably better not to experiment with the heroes with an oak broom.

Second possible variant– gasify the heater-basket like Vesuvius, see fig. on right. However, the warm-up time of the bath will remain "wood-burning", and the gas supply, so that the heat does not fly away in vain into the pipe, will need to be smoothly and gradually increased from a minimum to about 0.7 nominal within 1-1.5 hours. And most importantly: sauna stoves-baskets are not produced with an elongated firebox, i.e. according to safety rules, they are not subject to gasification; the firebox door with the burner base 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. In this case, naturally, we need the best gas oven. How to choose it? The rumor of the people, 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.

Quantity

In this case, this concept refers to the efficiency of the furnace. To calculate it, in addition to your own initial data, you need to know the gross calorific value of the fuel, or its calorific value. 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 / cu. 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 wish 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% atmospheric pressure- it is known specifically only to the local specific Barabashka, and to no one else.

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

Here it is necessary to take into account the fact that furnace manufacturers give gas consumption in them based on heating the steam room to 60 degrees; doctors say that at a higher temperature for women and children and at least something at least a little sick (including temporary malaise after yesterday and euphoria from recent libations) it is dangerous to bathe. The heat loss of a room actually depends on the temperature difference between 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 linear without noticeable error.

So, at 60 degrees and the efficiency of the furnace in 100% gas, 60/80 \u003d 0.75 x 1.8 cubic meters will be needed. m = 1.35 cubic meters. The choice of a furnace is generally simple: the closer the fuel consumption declared by the manufacturer to this value, the better the furnace. 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 steam room, then it means a swindler. Or he invented a perpetual motion machine, but he himself does not know about it.

Now let's check independently, according to the rumor of the people. For example, in the Russian Federation, Termofor Urengoy oven is in 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 consumption) / 1.71 (real for this furnace) = 0.79 or 79% Very good and very close to the truth indicator; Might be worth picking up this stove.

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 definitions of efficiency not yet developed. These devices, unlike bath stoves, are of long continuous use, so you need to somehow take into account the cost of heating and its reliability. Therefore, it is possible to choose more or less definitely only by comparison.

First, without worrying about dimensions and any other physics, we multiply the “expenditure” parameters: the hourly gas consumption declared in the specification by the cost of the device. We get some carelessly abstract value A. Then we multiply the “economical” indicators: thermal power by the duration of the company guarantee in months; we get the same value.

Further, too, nothing complicated: C \u003d B / A. The more C, the cheaper the heating will be. For comparison various models this is enough, and you can calculate the exact cost of heating, knowing the amount of heat demand, the calorific value 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 popular rumor with the sales rating. By sauna stoves in the Russian Federation, the already mentioned domestic Termofor and the Finnish Tulikivi are in the lead; for permanent infrared heaters - also domestic Bi Car and American Master. Recently, the Russian-Chinese Comfort has been erupting well. They speak well of him, but they have not been on the market for long. Therefore, having looked at the Comfort gas stove, it is advisable to consult with real users.

Gas Furnace Revolution

This revolution is connected with the advent of gas infrared emitters, or infrared burners; both are abbreviated GII. There is a difference between them; what - see below. For now, it is worth noting the fact: in terms of a set of parameters, including price, GII overtake conventional heating stoves, like a Porsche - a pre-war emka. For example, a GII with a power of 1.5 kW heats an area up to 12 square meters. m, he 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 residential premises. The price of a gigacalorie of heat is 1.5-2 times lower than from any other source. In addition, household gas stoves based on GII are significantly better than other heating appliances in terms of sanitary and hygienic indicators.

How is this achieved? Due to heat distribution similar to warm floor, see fig. The comfort zone is where people are, and heat loss through the ceiling is sharply reduced, 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 a warm floor, complex construction work is not needed, there is no thin winding pipe walled into the floor that can become clogged or leak (and how to repair without breaking the floor?) Unlike electric heating, it is not expensive electricity that heats, but gas, a unit of energy which is many times cheaper. Another plus is that the flow of warm air from the heated infrared floor is uniform over the area of ​​the 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 with microdoses; air is sucked in naturally without pressurization. In ceramic GIIs (scheme in Fig. yb; t), nozzle channels are made in a ceramic (most often carbon) plate, which itself heats up to 900 degrees. Thanks to high temperature in microcombustion chambers, 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 a catalyst mesh. The actual combustion catalyst is either a platinum coating (eternal, but expensive), or a nickel coating with additives (cheaper, but gradually burns out). Anyone who has used a windproof gas lighter is familiar with catalytic combustion.

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

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

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

Appointment and evolution

The first to go on sale were open ceramic GIIs for temporary heating of garages and outbuildings, pos. 1 in fig. Probably, it was the need to create a comfort dome 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 have fallen from 800 to 90-150 USD in 7 years; certification and a separate permit for the operation of garage GII is not required. In everyday life, ceramic GII have also been used to replace electric fireplaces, pos. 2, but this is just a mechanical translation 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 work, hunters, fishermen, tourists, yachtsmen and others who faced the problem of heating far from civilization. But these categories of users needed a large specific power in relation to the mass and dimensions, so they preferred catalytic GII.

The first samples (pos. 3) looked like their non-catalytic counterparts. In the end, the "suburban" branch of the GII evolution gave rise to a gas mini-oven (fig. right), which can be carried with you while moving on foot. However, there are few of them for 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 the radiating surface, power of the GII made it possible to organize warm islands directly in the open air, for this it was only necessary to assemble the radiating panels under the reflective umbrella and hoist it on a rack, pos. 4.

The efficiency and economy of heating with GII-“umbrellas” turned out to be so high that the question arose of using them for permanent heating of housing. At this time, warm floors were just widely dispersed; their sanitary and hygienic properties were not in doubt, but the question 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-mounted GII emitters are often made in the form of flat panels; in multi-storey buildings on floors below the uppermost, the overall efficiency does not noticeably worsen from this.

gas in cooking

The next area where gasification of stoves is not only useful, but simply necessary is culinary and technological equipment. A gas bakery oven, for example, takes up only about 10 sq. m of ordinary, non-industrial area and without requiring 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 advantage of this circumstance with might and main, and those who really know how to bake bread well, do a good business at home with always guaranteed demand.

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

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

Gas in the workshop

The high attainable 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. Just remember to leave a gap at the bottom for air access!

Small-sized and gas-fired melting furnaces, incl. desktop are also commercially available. But a do-it-yourselfer or an IP homeworker will have to be disappointed here: the fire department and the 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 do with electric stoves.

About gas fireplaces

The remarkable properties of natural gas gave rise to attempts to make a gas stove. 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, being wise with burners, sometimes create something similar to it, supposedly in modern style, see the figure on the right. However, the psychological and aesthetic significance of the fireplace traces its pedigree from a primitive tribe fed 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 staysail on a Predator with a 400-horsepower Mercruiser. It will float, once it floats on the water, but there will be no romance of sailing.

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

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 mechanism for shutting off the gas supply.

Buyers choose gas heaters for a low price, compactness, an understandable principle of operation 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 a window opening. Natural gas convectors use both natural gas and liquefied gas 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 country house 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 desired heating temperature is reached, combustion becomes less intense. If the fire goes out, the protective system is activated and the device turns off.

Catalytic gas heater

This type of device is powered by gas or gasoline. With it, you can heat a room of any size: from a small hut to a large warehouse. Heat is generated by the catalytic combustion process. It is distinguished by the absence of flames and any sounds, but at the same time, the active release of a large amount of heat. Heat is released due to the oxidation of the fuel 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 glass fiber with the addition of platinum. At the moment, instead of platinum, more relevant catalysts are used, which contribute to deep oxidation and not. Some models are equipped with a fan heater in order to increase power. A gas heater is able to quickly heat the air in the room.

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

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

Infrared or powered by gas pipeline. Models where an infrared ceramic gas burner is present differ from other infrared devices in the presence of an open flame during operation. Such devices serve for a long time and heat efficiently, 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. The market offers a wide range of devices with different configurations and mounts. It is not difficult to choose an infrared ceramic gas heater that fits perfectly into the interior and will meet all technical requirements.
