How to warm the house in winter if there is no gas. How to heat a house if there is no gas - a comparison of the effectiveness of various options. Universal heating boilers

To begin with, I would like to note that the most effective today is a gas heating system. If for some reason it is not possible to install it (for example, there is no gas line in the country house), give preference to electric heaters. Next, we will consider the most economical electric heating systems for a private house and apartment.

Why electric heaters?

You will immediately ask yourself why the classic water or stove heating of rooms is not considered? The answer is simple - it is due to the fact that installation work and maintenance for about the same money will be kept to a minimum.

Now we will provide several reasons why it is obvious that the best and most economical heating system for a private house is electric.

1. Heaters powered by electricity are silent, do not require additional resources (coal, firewood, liquid fuel) and, moreover, do not pollute the atmosphere. This suggests that in a private house it is not necessary to have a place in the utility block for fuel, to make a chimney and, moreover, to soot every year. It is enough to connect the system to the network and enjoy the heat.
2. Installing an entire electric heating system does not require a huge initial investment. For example, the installation of a water heating main is carried out once. A project is being created, all pipes, radiators, a boiler, as well as additional automation are purchased. To do part of the work (for example, in one room), and if you have money, you will not be able to complete the project over time, and if you do, then many problems will arise. It will be necessary to drain the water, crash into the finished highway, etc. In the case of electric heaters, everything is much simpler. You can install equipment in each room separately as you earn money. At the end of spring, buy convectors for the bedroom, later - for the kitchen, bathroom, etc.
3. Today there are many ways. Of course, this option requires considerable costs, but be sure that over time they will pay for themselves. The installation of economical, as well as solar panels on the roof of the house.
4. , a boiler or even a convector can be done with your own hands, significantly saving money on calling the master.

As you can see, electric heating in a private house really outperforms alternatives, therefore, it is quite profitable to install such a system.

To your attention, a video example of creating a cheap and at the same time effective autonomous system:

Homemade economic system electric heating batteries

Heating system options

So, consider the existing equipment that will make electric heating in the house economical and cheap.

Boiler use

, which will heat the water in the home heating system, warming up the room, is the first, least efficient option. Of course, on the Internet you can see a bunch of information that talks about economical boilers that can reduce consumption by up to 80%, but all this is nonsense. The only option to reduce costs is to install thermostats and various automations, which will turn on only when the temperature in the room drops, as well as at certain times of the day. All other talk about new product designs or reduced power is just a publicity stunt. If you buy a small capacity boiler, it will take more time to heat water for heating the house, so that's what it will come out with.

Using IR panels

A smarter solution and likely the most cost effective. The fact is that these products do not heat the air in the room, but certain objects (floor, walls, closet), from which heat is transferred in the future. If in the previous version hot air rises to the ceiling and immediately cools down, then in this case the heat is directed to the floor, which is more reasonable (people do not walk on the ceiling).

This diagram shows the effectiveness of an economical heating system for a private house:

You see everything for yourself, so there is nothing more to prove. It should only be noted that IR devices can work more efficiently if you add thermostats to them. One controller is enough to control three heaters in the economical heating system of a private house. We talked about that in a separate article.

Using convectors

Many manufacturers convince that an electric convector heats up the room efficiently and at the same time consumes a small amount of electricity. Of course, the question is debatable, because, in fact, the principle of operation of products is similar to the version with radiators (air rises). The advantage of convectors is that their installation and connection is not difficult. In addition, the heating of the heating element is about one minute, which is undoubtedly faster than in the case of water radiators.

Among the other advantages of electric convectors are:

• low cost (from 2 to 10 thousand rubles);
• fire safety (which is especially important when);
• you can gradually build up the heating system (one convector for a room is not enough, buy another one and connect it to the network without any problems);
• attractive appearance;
• trouble-free operation during power surges (also relevant in the private sector);
• compact dimensions.

The use of warm floors

We analyzed the reviews of buyers who used this option and saw that most people are satisfied with the purchase. The main thing is to additionally install a temperature controller to make economical electric heating in the house with your own hands.

Installation of a warm floor

Another modern and effective method economical home heating is the use of electric heating mats. They fit under flooring and warm the room through the floor. As a result, warm air rises, completely warming up the room. The underfloor heating system is best installed in combination with additional source heating, for example, IR panels.

Speaking about the heating mats themselves, I would like to highlight the products of EKF. You can choose heating mats exactly for your conditions - ready-made kits vary in size and power. Thermomats EKF can be controlled by a mechanical or electronic thermostat, which can be programmed on/off for a week. In addition, I would like to highlight the full shielding of current-carrying wires, due to which there is a uniform heating of the floor surface. You can find out more about EKF heating mats by clicking on the link: https://ekfgroup.com/catalog/sistemy-obogreva/sistema-teplyy-pol.

Which option is better to avoid?

We talked about cheap and efficient economical heating systems for a private house, but I would also like to note the most costly options that need to be avoided. The top of the ranking is occupied by oil coolers. They are all known for having high power, so when working in winter, you can see a noticeable increase in electricity consumption.

Not only do these products have high power, but also their heating efficiency is very weak. For example, an IR panel of the same dimensions and the same power will make the house warm faster, so it’s better to give preference to it.

In addition, the infrared heater is installed on the ceiling or wall, thus does not take free space, which cannot be said about electric radiators.

Another non-recommended option is fan heaters. These devices not only burn oxygen, but also “chase dust”, besides, they are noisy. The effectiveness of their use is not too great, because. between the ceiling and the floor, the temperature may differ by several degrees, despite the fact that the power of the products is high (from 1.5 kW).

How to improve efficiency and reduce costs?

Just buy an economical electric heater and install it in country house this is only half the battle. At the same time, it is far from a fact that as a result of the work you will be able to verify the significant efficiency of the economical heating system made. The reason for this may be poor thermal insulation of the room. All kinds of cracks, gaps in the windows and even the absence of insulation on the walls contribute to the rapid cooling of the room. It has been proven more than once that with high-quality insulation of walls and ceilings, heating efficiency can increase up to 80%, although this figure usually reaches 40%.

Another important nuance is the use of automation. For example, if there is no one at home all day (everyone is working), then there is no point in heating the rooms. It would be more correct to install a controller that will turn on the heaters an hour or two before your arrival. This time will be enough to fully heat the premises.

The price of fuel for the home in different areas varies significantly. Because of this, regional stereotypes have long been formed - the cheaper it is to heat a house, as well as the decisions on the selection of heating equipment and the creation of heating systems. But prices change over time cheap heating becomes expensive. Energy prices are leveling off.

The question becomes especially important right choice fuel at a time when it is significantly more expensive. \"European character" of fuel prices, in the absence of European salaries, makes the struggle for energy savings similar to the struggle for survival.

First of all, warming the house, as well as other heat-saving measures, will help save money.
But the choice of the optimal type of fuel is paramount, for everyone who wants to reduce costs.

What can be used for home heating

For heating a private house is usually used

• firewood;
• coal;
• pellets;
• briquettes;
• main gas;
• gas from cylinders;
• gas from a gas tank;
• diesel fuel;
• night electricity;
• daily electricity.

When creating heating in a private house, as a rule, it is possible to use at least two various kinds fuel, for redundancy and increased convenience.

Non-reserve option - non-automated solid fuel heating with a gravity system due to the high cost of creation, the inconvenience is a thing of the past.

Now it is much more expedient to use forced systems with a pump and provide the ability to heat two or more types of fuel.

Specific figures for the prices of fuel and equipment will not be given, since they are different everywhere and change quickly and “promise to grow” ...

Firewood, coal, briquettes

What unites these types of fuel is that they are burned in a solid fuel boiler.
Firewood is the cheapest. And even 1 kW of energy obtained from them is cheaper than that of coal (for most regions, except for coal - Kuzbass, Donbass).

But there is another problem with firewood - a large amount of work on their use. In fact, you need to be on duty at the boiler, regularly throwing up fast-burning low-calorie (4.2 k- for dry firewood!) Firewood. Or hire a stoker.

Coal is less of a problem. In a normal heating system, in fact, it is enough to throw fuel 1 - 2 times a day. But then - recycling, removal of ash.

Briquettes are artificial firewood, clean and beautiful, they burn more slowly, almost 2 times more expensive than firewood. In fact, they are an option for a quick heating \ "from the trunk \" for giving for the weekend.



Pellet burning

Pellets - give great convenience compared to a conventional solid fuel boiler and firewood. Fall asleep, serve - once a week. But the cost of the equipment and the fuel itself is several times higher. In fact - "problem-free firewood for the rich."



Gas from the main

If the price of natural gas is the lowest, then it is the best option for heating. In terms of price / convenience - without any competition.
But with a large increase in price, with the cost of connection not decreasing, its expediency drops sharply compared to firewood, in fact, people stop connecting.

Also in the Moscow region, where, with the low cost of the fuel itself, the price for connection exceeds one million rubles. even electricity becomes more profitable.



Gas from cylinders and gas tank

Due to the extreme inconvenience, severity of use, as well as the very high price, gas from cylinders can be recommended as a last resort. After all, carrying balloons several times a week ...

Gas from a gas tank is a completely different matter. The price is high, but the convenience goes to the level of ordinary main gas, so it makes sense to consider the option .... Please check with local service providers for prices. In any case, a gas tank can be an alternative to pellet heating due to its trouble-free nature.

diesel fuel

Expensive type of fuel, and not environmentally friendly. The smell will follow everywhere. Cleaning the boiler is also not a rare "pleasure". Heating with diesel fuel with a special boiler, due to the transformation of the site into a "mechanic garage" at a high price, cannot be recommended under normal conditions.

Electricity

The most expensive type of fuel, more expensive than diesel fuel and gas from cylinders. The cheapness of the boiler and the best ease of use, according to many, does not cover the price of electricity in any way.

But perhaps in the region there is a night rate, which is several times less than the day rate. Night electricity, given the convenience of use, becomes competitive for home heating. Even 4 kW on two-phase power (220 V) all night can add a significant amount of convenience to home heating.



What is commonly used for home heating

In the first place is still natural gas, as the winner of price / convenience, but in those regions of the CIS where there is no absurdity in prices, both for the fuel itself and for connection.

With firewood, somehow you need to get away from the continuous stoker. Boilers long burning with a huge load in a barrel-shaped body is far from the best option. In general - \"nonsense in terms of price / convenience \", they have many shortcomings.



The best option is an ordinary powerful solid fuel boiler (2-3 times more powerful from heat loss) and a heat accumulator - a buffer tank. As well as a large internal heat capacity of the house itself. To increase convenience, it is advisable to connect an electric boiler with a night rate to this scheme. The addition of electricity in general will not greatly increase the cost, but it will add comfort.



Where coal is cheap, firewood is not heated. In the Donbass, it would never occur to anyone \"suffering with firewood\". Often coal as a whole costs and is not more expensive in other regions. But we are talking only about high-calorie high-quality thermal coals of grades A anthracite, and T skinny. The fraction is also important - no smaller than a seed, preferably a nut. A universal powerful solid fuel boiler will always help out ...

Pellets are heated when money is not particularly considered. Heating with diesel fuel, although similar in price to pellets, cannot be recommended under any circumstances. If there are no financial problems, then a gas tank is even better, in fact, the same natural gas, you just need to take care of bringing it once or twice a season.

If there really is “zero attention to finances”, then you can simply heat
electricity, the best convenience and ecology.

In general, it remains only to find out all the prices from local suppliers, and calculate, comparatively by heat losses, how much the equipment, fuel will cost per season and 12 years (equipment payback), and also think over all the concerns for the delivery of fuel for the home, its storage, use ….

Today I will try to reveal a useful topic, the thing is that now many citizens of our country live in private homes, and when winter comes, they ask themselves the question - what is really more profitable to heat a house? The first thing that comes to mind is, of course, gas, electricity, firewood (coal can also be included here), there are, of course, more non-traditional sources for heating, such as diesel or gasoline, but it is difficult to use them, and sometimes even dangerous. In general, let's think about what is now more profitable and what is preferable ...

In this article, I will try to give a full assessment of one or another heating system, that is, we will estimate according to the calculations and derive the optimal source of heating. Of course, now electric heating is starting to progress, but about 60-70% of households are still steadily “hanging” on gas, and many apartments now have the so-called! So why is it so beneficial? For example, I want to take an apartment or a house with an area of ​​100 square meters, this is what I consider “optimal” for a family of three to four people (what a comfortable area you can). In general, read my reasoning and calculations below. Let's start with the condition.

Given conditions

As I wrote above, the task is to heat a house - an apartment of 100 square meters, according to our SNIPAM, it can be argued that for comfortable heating it is necessary to apply thermal energy of 100 W - a square meter, that is, if we have 100 square meters, we need energy - 100 X 100 \u003d 10,000 W or 10 kW, is that a lot? Of course yes, a lot!

I propose a simple circuit, but it will display the completeness of the picture:

• Let's say it's cold now, the heating of the house (apartment) works in the mode - it heats for 5 minutes, it rests for 5 minutes! Thus, we get that the heating works exactly 12 hours a day! Of course, if your home is well insulated, then this interval will not be 50/50, the heating will turn on less often, but this is very good insulation with foam plastic on the outside and thick walls, of which there are still few in ordinary (ordinary) houses!

The conditions are set, we begin to identify - which is more profitable:

Gas heating

Firstly, you have gas, which in itself costs money, and not small ones.

Secondly, a boiler with a capacity of only 10 kW will be enough for such an area, that is, you do not need to buy for 20 - 25 kW, there is simply no need. Here you can still consider 15 kW, but if the boiler does not work at 100% load, its resource increases.

Thirdly, at the moment gas costs about 2.5 - 3 rubles, it all depends on the geography of our homeland. I have 2.5 rubles in the city, so I will count at this rate.

Gas is a very "energy-intensive" product, a lot of heat is released during combustion! Heating boilers now have a very high efficiency (often it is not lower than 80 - 90%) - it takes up little space, works offline and requires virtually no maintenance. As it becomes clear, the boiler itself cannot heat the room, it needs a heating system, usually these are cast-iron or aluminum batteries that are “tied” to - a reasonable solution.

Well, we have decided, let's move on to gas calculations

I have a very clear example of such a house (not insulated very well, there are old places that need to be further insulated), gas goes out (in cold weather) about 10-12 cubic meters per day, let's take a maximum of 12.

If we derive the final consumption, then 12 X 2.5 p \u003d 30 p. Then for a month it turns out 30 X 30 days = 900 rubles! Tolerant!

Heating with electricity

Such systems do not require complex engineering networks, in fact, just ordinary poles with electricity wiring - this makes such systems very attractive.

I would like to note right away that now there are a lot of systems that strive to make electric heating cheaper and more efficient, I will list it point by point:

• Heating boilers are a boiler in which there are electric heating elements, and it, like gas, heats the coolant (usually water or antifreeze) in the system.
• Electrode boilers, instead of heating elements, special plates are used there that heat water more efficiently.
• Separate heating elements, just cut into each battery.
• Heated floors, there are both film and wire. Usually they are laid in the floor, or in the version with a film they are hung on the ceiling under the main coating.
• Infrared heaters. The form of panels that are hung on the wall and heat the room with infrared radiation.

You can still list for a very long time, now there are still a lot of varieties, and every manufacturer wants to declare that he has simply invented “know-how”. But in fact, again, it all depends on how your house is insulated! The walls must be warm - otherwise you will just drown the street.

Now a kilowatt of electricity costs about 3 rubles (I take the average for the country).

Well, let's assume - that some manufacturers still managed to reduce energy consumption to 80 W - meter, while dissipating heat like a gas at 100 W - meter.

We have already decided that our heating works for 12 hours. Then we multiply 80 W by 100 meters = 8 kW / hour. And since we heat the house for 12 hours, then: - 8 X 12 \u003d 96 kW per day!

If you knock out money, then this is 96 X 3 p. = 288, per month 288 X 30 = 8640 rubles! Just "FUCK"!

Not very profitable heating!

Firewood, coal and more

Many people can now ask me a question - why are we considering this option, no one has been drowning like that for a long time, and you can’t heat an apartment like that! But no guys, it’s still relevant, remember the same “pellet” boilers, of course, this is logical only for a private house, we will not mount such a system in an apartment.

Firewood

I don’t even know how to present the calculation to you, here you can’t somehow deduce the amount of firewood and the heat received from them. It all depends on the material, what kind of firewood it is (oak, birch, pine, etc.), because everything burns differently and gives different heat. But I can say with confidence that you need to make some kind of shed to store this firewood or coal - 100%, which already weighs down many owners.

You can heat with firewood really cheaply and even for free, if you yourself cut them somewhere and brought them. But if you buy, then KAMAZ (about 6 cubic meters), and that is how much you will need for the heating season, costs about 10 - 12,000 rubles, if divided by 6 months of heating, this is about 1.5 - 2,000 rubles. per month!

Coal

Coal will come out a little more expensive, but you need less of it and it keeps the temperature longer (we buy about 3 cubic meters). If knocked out in the bottom line, these are the same 2000 rubles. - month.

Pellets

A new heating system, special expensive boilers, which, by the way, can be well automated.

They are heated with special pellets - “pellets”, it is also not easy to calculate consumption! But again, based on my experience, I will say - the consumption of pellets per month for 2 - 2.5 thousand rubles - our 100 square meters.

CONCLUSIONS - BENEFITS!

Well, as you yourself understand, GAZ is really in the first place, while in terms of efficiency it does not even have close competitors.

The second is to burn wood, pellets, coal - but in our case this is not an option at all (troublesome, garbage, dirty and dangerous), unless you have a private house and the "ash" from burning will come in handy for seedlings.

The third is electricity itself, of course, many can now tell me - what did you count here, I have much less, I spend 4000 - 5000 rubles per 100 square meters. - a month, for electricity! Guys, this may be true, but think about how much you would have spent on gas then? Basically a penny! Many are heated by electricity only because there is no choice and will not be, because the area is remote and there is simply NO gas nearby!

Now the video version of the article

Here is such an article turned out, I think it was useful to you, read our construction site.

It does not matter how to heat the house in cold weather - it is important to cover its heat loss.

So, cold weather outside the window and the temperature in the house begins to drop. In order for the temperature in the house to be comfortable in cold weather, each dwelling should have a heat generator. What acts as a heat generator - a boiler, a furnace or a heat pump, is not so important. It is important that its capacity is enough to cover the heat loss of the house in winter.

Well, when the "overboard" temperature drops to -30C and -40C, it's time to "wind the pot" to its fullest. How to heat a house in cold weather - this is the question that any owner of a private house sets himself. We will consider it from the point of view of practice.

What is the best way to heat a house in terms of convenience

What is the best way to heat a house? It doesn't matter what, as long as this fuel is available to you and affordable. What is the point of giving advice or gas to those people to whom neither one nor the other resources are available.

Of course, it is better to heat the house with gas - natural (main), which enters your house through a pipe. This is the most convenient and cheapest type of fuel at the moment. And even after the government introduces social norms for gas, this type of fuel will still remain the most affordable for people.

Of course the most comfortable view fuel - natural main gas.

How to heat a house in winter if there is no gas near your site or the cost of connecting to a gas pipe goes off scale for 1,000,000 rubles? Next in convenience, but not cheap, is electricity. The most hassle-free energy source, you do not need a lot of money to install equipment. But a lot of money will be needed to pay your electricity sellers - the power company in your area.

What is the best way to heat a house if there is no gas, and the allocated electricity for your household does not exceed 5 kilowatts? The next option in terms of convenience is this. Before the start of the season, a tank with diesel fuel is brought to you and 3-5-10 tons of diesel fuel are poured into your container, depending on the capacity of your boiler and the area to be heated.

If this is not the case and you yourself go to a gas station with canisters, then this option can be compared with heating with used oil. The same process of assembling shareware fuel. Only a mining burner costs a little more than a diesel burner. The cost of a diesel burner is 15-25 thousand rubles, the cost of a burner for waste oil is from 60 thousand rubles. But fuel costs you almost nothing.

Next in terms of ease of use are pellets. A pellet boiler will require a one-time load of fuel before the season if you have a large pellet bin with a volume of 10-20 cubic meters with pneumatic supply.
If this is not the case, then you will have to regularly load the pellets into the bunker. It's good if you have an extended pellet bin for 600-800 kilograms. If the standard is 200 kilograms (they are usually put on the basic configuration of pellet boilers), then you will have to approach the boiler with bags of pellets every day). And believe the practice, loading pellets every day to a level above your head and pouring pellets into the bunker is not an occupation for the weak.

Next in terms of ease of use are firewood and coal. Do you want to be a stoker or stoker in own house? Then this option is for you.
There are, of course, coal-fired boilers such as Carbobot and wood-fired convective and which allow you to approach boilers and stoves less often.
However, calibrated washed coal for Carbobot needs not only to be specially prepared, but also to be obtained from somewhere in your area.
And pyrolysis ovens are not as good as they say in the brochures sellers of ovens.

Why didn’t I mention gas tanks and other conditionally autonomous sources gas heating? Because for the cost of installing equipment it is easier to pay an entry fee for connecting to the main gas and generally forget about problems with filling a gas tank.

The cheaper it is to heat the house in winter

We examined the better to heat the house in terms of convenience. Now let's see how cheaper it is to heat a house in winter, starting from small sub-zero temperatures and ending with real frosts.

The cheapest type of fuel is free fuel. Of course, absolutely free fuel does not exist. You spend money and your personal time on fuel delivery. However, if we abstract from the cost of delivery, then we can call.

Sawdust, lumber trimmings, used packaging cardboard, paper and pulp production waste, straw, bagasse, waste oil - all this fuel costs nothing. You just need to find its sources and organize delivery. If you succeed, you can heat your house in winter for free (conditionally of course).

If your stove allows you to burn anything in it, then your option is free fuel.

How to heat a house without gas

How to heat a house in winter if the “blue fuel pipe” does not fit your site and is unlikely to fit in the near future? Otsatetsya not hang up your nose and decide how to heat the house without gas in the winter.

Let's go in order (according to the degree of appreciation):

• firewood / coal,
• used oil,
• pellets,
• ground heat (heat pump),
• diesel fuel,
• electricity.

Here is such a "gentleman's set" in case Gazprom forgot about you and does not want to remember.

Heated area of ​​the house during the cold season

There is one option that will reduce the cost of heating your home. The effective heated area of ​​the house is the area of ​​those rooms in which you will maintain a comfortable temperature from +18C to +22C.
The effective heated area of ​​the house may include bedrooms, a bathroom, a living room. In other parts of the house - pantries, boiler rooms - you can keep the temperature at a level of + 8C to + 12C. In vestibules and fuel storage it is possible to keep the temperature from +5C to +8C.

Thus, you can greatly reduce the cost of heating the house as a whole, just by lowering the constant temperature in those rooms where you are not constantly.

Close some of the rooms in the house for the winter - and your heating costs at home will decrease.

If there is no gas in the house, then heating can be built on solid fuel or electricity, or better, on a combination of both. The more diverse the heating sources, the less likely it is that the system will fail.

For example, the installation of a solid fuel boiler can be supplemented with an electric convector for each room. You can combine a Russian stove on the first floor of the house, and infrared heaters on the second floor. However, electric and solid fuel energy sources are not the whole list. So let's start in order...

To heat a house without gas and electricity, you should think about the energy of burning solid fuels:

• brick ovens;
• metal ovens;
• solid fuel boilers.

There are also fireplaces, but it is difficult to classify them as a home heating system, since they can only heat one room with their help.

Boiler operating conditions

The main models of solid fuel boilers are designed so that the air flow that provides combustion is directed by a mechanical thermostat with a chain drive. In this case, the natural draft of the chimney must be ensured. However, for the normal operation of the boiler, a number of conditions must be observed:

• Place the branch pipe so that it is not higher than the incoming pipe.
• Provide the system with free communication with external environment using an open expansion tank located at the top.
• Create a pipe system with optimal diameters and a minimum number of dead ends.
• Equip the boiler with fire safety equipment.

Price

The cost of solid fuel boilers varies in a very wide range - from 20 to 300-400 thousand rubles. It all depends on the design and capacity.

However, despite the price, solid fuel boilers are leaders in sales among home heating equipment without gas and electricity.

The difference between a liquid fuel boiler and a solid fuel boiler is insignificant. To obtain thermal energy, liquid fuel is poured into a liquid fuel boiler instead of coal:

• diesel fuel;
• fuel oil;
• kerosene;
• vegetable oils;
• alcohol.

The last two are given only as an illustration of the possibilities. The use of oil and alcohol is from the section of unaffordable luxury. And the point is not even that alcohol, for example, is very expensive, but that this fuel is obtained from vegetable raw materials that could be used for food production.

Peculiarities

A distinctive feature of liquid fuel boilers is high efficiency - up to 92%. In addition, for installation and operation, permission from special services is not required, unlike, for example, gas boilers.

Price

The price range for such boilers ranges from 25,000 to 180,000 rubles and depends on the manufacturer and the volume of the combustion chamber. The average annual cost of heating a private house is 150 sq.m. without gas and electricity on diesel fuel about 150,000 rubles.

Which is higher than the cost of solid fuel and even electricity.

Transform solar energy in thermal it is possible only if the sun shines often and for a long time over the roof of your house. Unfortunately, 80% of the territories of Russia have nothing to do with this. However, even in a warm climate, you cannot rely on solar heating alone; you definitely need a backup source.

Principle of operation

Light-absorbing batteries are installed in place "under the sun", which convert solar energy immediately into heat, and then transfer it to the coolant. There are two types of solar collectors - vacuum and flat. Vacuum are considered the most efficient and economical. The use of solar energy is an achievement of science.

Price

The advantage of solar heating is the low price of solar collectors. flat devices can be purchased at prices ranging from 1,500 to 60,000 rubles. Vacuum ones are much more expensive - about 80,000 rubles. However, if you consider that you don’t have to pay for fuel, then the price is quite adequate.

Biofuel use

Biofuel is any organic material that can burn. However, these terms have recently come to be understood as the use of gases emitted by rotting organic matter.

Principle of operation

For a source of such gas, anything that rots with sufficient intensity is suitable. Usually use manure, food waste, plant mass. All gases formed during the process of decay burn perfectly and replace natural gas.

The biofuel heating plant itself consists of units that collect, purify and feed the emitted gas to the boilers for combustion. And then the principle of operation is the same as that of a natural gas boiler.

Minuses

A significant disadvantage of this method of heating is the low productivity of decay in natural conditions. In order to accelerate this process, it is necessary to increase the temperature, and this is the cost of energy.

For this reason, it is impossible to use biofuel as the main method of heating a large house, but to heat small house or create an auxiliary system is quite possible.

Biofuel heating is widely used farms countries such as Greece, Spain, Portugal.

Such heat is extracted from nothing, just from the air. It's an air conditioner in reverse. The pump itself does not produce heat, it only extracts it from the environment and sends it in the right direction.

Operating principle

The principle of operation of the pump is to take heat from the environment in which it is placed. However, the pump needs starting energy. For example, in order to move 10 kW of thermal energy, it needs to consume about 3 kW of electricity.

The difference is impressive! And in the presence of electricity, allows you to make a choice in favor of heat pump for economical heating of a private house without gas.

Features and prices

However, the problem is that in severe frosts such a pump fails. Works well at frosts down to -15, stops working at -30. There is another drawback - with practically free energy, the pump itself is very expensive - from 200,000 to 1,500,000 rubles.

Once they were called potbelly stoves. This name comes from a long time ago. civil war and subsequent devastation, when the simplest joys of life were associated with great wealth.

Much has changed since then, but the iron stove is still called a potbelly stove. Now they look different. Many of them are equipped with fire-resistant glass windows, but their essence has not changed - they heat up quickly and cool down just as quickly.

Maybe that's also why this stove was called a potbelly stove, because to maintain a constantly high temperature, a lot of firewood is required in a bourgeois way.

folk fantasy

In the Siberian taiga huts, where it is possible to bring a cast-iron stove, but it is difficult to deliver a brick, a potbelly stove is lined on three sides with large stones run in by a river. It turns out beautifully and functionally - the stones heat up and slowly give off heat to the air.

This approach is applicable to the conditions country house- when the house is built, and the heating is not yet ready. To some extent, the stones perform fire-fighting functions, absorbing random sparks and excessive heat. Stone structures can serve as a reason for the designer's imagination to fly.

The efficiency of a metal furnace will increase if it is equipped with a coil for heating water and heating batteries are connected to it.

Brick ovens or Russian ovens

In its classic form, the Russian stove is a miracle of engineering soap with a very efficient system heating. Not only did the stove heat the entire hut, it was also a multifunctional kitchen, a heated bed and even a bathhouse.

Nowadays, a number of functions of the Russian stove are not needed, but as heating in a private house without gas and electricity, it is effective!

In modern conditions

Making an ancient Russian stove modern is quite simple:

• If one of the sides is built into the wall that separates one room from the other, then two rooms will already be heated. However, the stove has four sides.
• If you manage to build a stove into two walls of two different rooms, then you can heat almost the entire house.
• If the house is large, then the forces of one heat source cannot be dispensed with - you will have to make a system of pipes and batteries with a water heating element.

The Russian stove differs from a simple brick one in size and in the absence of a stove bench. The brick oven has a large inertia - it heats up for a long time, but it also cools down for a long time.

To make the cooling process last longer, there is a damper system that retains hot air. However, it is precisely in this system that the greatest danger of the furnace lies - if the damper is closed ahead of time, then carbon monoxide from the furnace will not go into the pipe, but into the house.

Price

Construction cost brick oven depends on a number of factors: firstly, on the size, secondly, on the selected materials, and thirdly, on the remuneration of the stove-maker. And the work costs the most.

So, if the stove-maker takes moderately, and you are not going to decorate the stove with marble and ceramics, then you can meet 20-60 thousand rubles. Expensive or not - everyone evaluates in their own way. However, one should take into account the fact that the furnace will stand idle for more than a dozen years.

How to heat the oven

You can heat everything that burns. The classic option is wood and coal. However, the following sources of thermal energy also went into the furnace at all times.

Kizyak

Kizyak is completely dried cow dung. It burns well and leaves almost no ash. Horse manure can be used for the same purpose. By the way, there is no smell from such fuel.

Peat

Peat, or rather, peat briquettes. In terms of calorific value, this is something between firewood and coal. Briquettes are burning in an already heated firebox. This means that you first need to melt the oven with wood, and then lay the briquettes.

Advantages - peat is environmentally less toxic than coal.

More precisely, the toxicity of peat smoke can be equated with the toxicity of firewood. Only from peat there is more ash and smoke. You can only talk about the benefits of using peat if you have the opportunity to buy it at a low price. In all other cases, it is better to use firewood and coal.

Firewood

Firewood burns quickly and is not always hot. To support high temperature in the house you need not just a lot of firewood, they need to be put in the firebox all the time.

Coal

It is best to use coke. Coal burns for a long time, and good coked coal is also hot.

If you use black coal with low ash content and high calorific value, then one measure of coal can give as much heat as 3-5 such measures of their firewood will give. The only argument against coal is its high ash content.

Ash from coal is toxic, so there will be a problem of its disposal.

More

There are other substitutes for firewood. For example, seed husks or corn cobs. Both burn well, but not for long, and without strong heat. However, these types of fuel should not be taken seriously.

Thus, from all types of solid fuels, it is worth choosing firewood and coal. And, in combination. It is good to use firewood for kindling the stove, and coal for a long and slow burning.

Instead of a conclusion

For heating a private house without gas and electricity, there are a dozen systems - from a classic stove to solar energy. It is difficult to advise on which of them to stop. However, I can give one universal advice - try to form a multifunctional system with redundant functions and minimizing risk, like on warships.
