What is more profitable gas or firewood. The cheaper it is to heat the house. Wood or LPG? Tradition vs technology

In order to heat a country house, cottage or cottage, you need fuel. Well, if it is possible to connect to the gas pipeline. What to do if it is not? Let's try to understand the pros and cons of other heating methods.

Heating with electricity

High price. If natural gas is the cheapest source of energy, then electricity is, if not the most expensive, then one of the most expensive. One kilowatt-hour of electricity will cost For comparison, a kilowatt-hour of natural gas costs, and propane-butane -. For a year, this difference can result in tens and hundreds of thousands of rubles of additional expenses.

Insufficient selection. The general availability of electricity (unlike natural gas, it is really everywhere) does not mean at all that there will be enough energy to heat the whole country house. The power consumed by the heating system will not be pulled by any suburban power grid. If the network fails, solving this problem is almost as difficult as building a main gas pipeline.

Disadvantages of electric heating

• High price.
• Voltage drop in the network in cold weather.
• Insufficient electricity supply.

Heating with liquefied gas

Propane-butane is a liquefied gas, which is filled with gas-powered cars and well-known "country" gas cylinders of red color. He gives the best combination prices and comfort after natural gas.

For autonomous heating of a private house with gas, it is necessary to install an underground gas tank on the site. One gas tank holds several thousand liters of liquefied gas. This volume is enough to heat the house for many months. When the gas tank is empty (this happens once or twice a year), it will be replenished by special refueling vehicles.

Low price. Propane-butane costs one and a half to two times cheaper than electricity or diesel fuel: per kWh versus electricity and diesel fuel.

In practice, this means the difference between - how much heating costs 100 square meters liquefied gas for a year - and - a much more significant amount that would have been required to shell out if using diesel fuel.

Convenience. Like natural gas or electricity, propane-butane is supplied to the heating system without human intervention. This is not firewood or coal, which you need to throw up several times a day. Liquefied gas does not require regular loading and constant supervision. The gas tank needs refueling once or twice a year, and this is done by a specialist, not a homeowner. It may be necessary to clear the snow in winter so that a filling truck can drive up to the site. This is the worst thing that can happen.

Doesn't take up space. The gas tank is located underground. You can walk on it, you can grow on it herbaceous plants and even bushes. During operation, the gas heating system does not emit a noticeable odor. No comparison to firewood, coal, pellets or diesel fuel, which will take up space on the plot or in the house to store.

Disadvantages of heating with liquefied gas

Heating with diesel fuel

Heating with diesel fuel will also require a tank, and the cost of installing it will be comparable to the cost of autonomous gasification at home. At the same time, unlike propane-butane, diesel fuel cannot be called cheap.

High price. Diesel fuel is the most expensive source of energy used for autonomous heating of a private house. A kilowatt-hour of diesel fuel costs. Even electricity is a little cheaper. It will probably be difficult to spend more on heating.

Bad smell. This is an inevitable property of diesel fuel. A strong smell will follow the unfortunate owner of a diesel tank everywhere.

Gas or electric boiler?

The house will smell like in a garage, and on the site - like from a working tractor, and nothing can be done about it.

Problems when using low-quality fuel. The use of low-quality diesel fuel can lead to serious damage heating equipment. Those who use liquefied gas and gas tanks AvtonomGaz do not have such a problem: the quality of propane-butane does not affect its consumer properties.

Disadvantages of heating with diesel fuel

• High price.
• Sometimes you have to clean the snow for winter delivery.
• Strong smell in the house and on the site.
• Use of storage space.

More about the cons of diesel fuel: Why is LPG better than diesel?

Heating with coal or wood

Firewood and charcoal have the same disadvantages. They need to be loaded very frequently (so often that big house, you may need a stoker), require regular cleaning of the ashes, and their storage takes up a fair amount of area on the site. In addition, they also emit a strong odor.

Firewood needs to be loaded into the heating system three to four times a day. During the season, this will take at least hours. More than three working weeks of continuous physical labor, worked from start to finish. Not surprisingly, many people prefer to find a stoker. However, this in turn affects the price. Taking into account the payment of the stoker, the annual heating of a house with an area of ​​100 square meters with the help of firewood will cost. This is more than the same amount for diesel fuel () or electricity ().

Coal is not particularly better in this sense. It must be loaded into the heating system two to three times a day, that is, a little less often than firewood. As a result, the time (and, accordingly, money, if you have to pay the stoker) costs a little less than when using firewood, but the difference is insignificant: for heating a house with an area of ​​100 square meters, taking into account the payment of the stoker.

In fairness, it should be noted that this problem has a partial solution. There are special boilers with a bunker, in which coal is refueled not several times a day, but only once every three to four days. This is a significant improvement compared to refueling every few hours, but against the background of propane-butane or even diesel fuel, it looks rather pale.

Warehouse place. A feature of firewood is the need for a large room for storage and drying. So that up to 40% of energy is not spent on evaporation of moisture, they must be dried for three years. A large room will occupy a part of the site, which otherwise could be found more useful application. Coal storage also requires a significant area.

Danger of poisoning. An unpleasant smell is a constant companion of any type of solid fuel, but in this case we can talk about a threat not only to the sense of smell, but also to life. If the boiler room is located directly in the house, when using solid fuels, the risk of carbon monoxide poisoning cannot be completely excluded.

Disadvantages of heating with wood or coal

The smell in the house and on the site.

Part of the site is occupied by a warehouse.

Heating with pellets

Fuel pellets made from peat and wood waste, differ from firewood in higher density and calorific value.

This is the most profitable and comfortable solid fuel, but all its advantages outweigh the already familiar disadvantages: the need for frequent loading, a strong smell, a large room for storing bags of pellets.

Low price. Pellets are surprisingly cheap: only per kWh.

If they didn't have to spend so much time loading, they would become the cheapest type of fuel. But time still has to be spent, albeit less than when using coal or firewood. Pellets should be loaded at least once a week, and taking into account the work of the stoker, this type of fuel can be considered average in cost, but by no means the cheapest: for heating one hundred square meters during the year.

Disadvantages of heating with pellets

The need to clean the ash and pay for the stoker.

The smell in the house and on the site.

Part of the site is occupied by a warehouse.

With the rise in energy prices in Ukraine, a population of swindlers has bred, promising to heat at least an apartment or a factory shop “for three kopecks”. In commercials, miraculous devices appear either from submarines or from spaceships, which, with scanty energy consumption, give out hundreds of gigacalories of heat. In a stream of lies they really drown helpful tips specialists. The latter do not promise miracles, but they know how to put the laws of physics at the service of people. myths

1. Heating with electricity is cheaper than with gas

Not true! 1 kilowatt-hour of electricity costs UAH 0.2436-0.3168, 1 cubic meter of gas costs UAH 0.7254-2.6856. (depending on consumption volumes). If you burn up to 6,000 cubic meters of gas per year (the vast majority of the population), the tariff will be 1.0980 UAH / cubic meters. m.

And now let's calculate how much "electric" and how much "gas" heat costs.

1 kWh releases about 860 kcal, 1 cubic meter of gas - about 10,000 kcal. Let's reduce the indicators to a common denominator, and it turns out that heating with gas is 3.68 times cheaper than with electricity. True, a modern gas boiler has an efficiency of 0.91-0.93, while any electric heater is almost 100%. But even taking into account losses, gas is more economical than electricity in the ratio of 1:3.4.

2. Not all electric heaters are equally efficient.

Whatever you heat the room with - a fancy oil radiator, a convector, a blower or an infrared emitter - the coefficient useful action them, as mentioned above, will be close to 100%. In other words, the electricity pumped out of the socket with the help of any "intermediary" will inevitably turn into heat.

In this sense, the so-called electrode boilers no better than ordinary tenovyh. Talk about the fact that they heat the water "directly", in connection with which they supposedly have increased efficiency, is pure bluff. In addition, these semi-handicraft products are dangerous to use, so you will not see them for sale in official retail chains, either in Ukraine or abroad.

The same field of berries - "system of heat-insulated floors", film electric heaters, etc. As for comfort, the listed devices can still compete with classic devices, but, sorry, they have nothing to do with savings.

3. There are electric heaters with an efficiency of more than 100%

Here we are dealing with terry crooks on the one hand and illiterate buyers on the other. A separate song is corrupt officials who throw government money down the drain for kickbacks.

The author once had to deal with the chief mechanic of one of the major railway stations in the region. Having a functioning gas pipeline at his disposal, this well-wisher for some reason decided to heat the station building with electricity. And it would be fine for this purpose to purchase a factory heating element or, at worst, a self-made electrode boiler. So no, he entered into an agreement with a certain company that delivered a “vortex electric heating installation” on a turnkey basis. The product, for which a separate shed had to be built, consisted of a powerful electric motor with a vane pump and a "secret" box. water under high pressure passed through the box and, as a result of throttling, heated up, then entering the batteries. The roar in the barn drowned out human speech.

Any heating engineer student will tell you that the efficiency of such an installation reaches 80% at best. And at a price it is many times higher than a standard electric boiler. When asked how much energy this monster eats, the mechanic said: “What's the difference? Anyway, we eat from the contact network!”

Charlatans even spud the officials of the regional center. Five years ago, in the building of the regional administration of the Pension Fund, we had to observe electrode boilers “from a submarine”, with the help of which an uninsulated “glass” was heated.

4. Alternative - in a heat pump

One of the former governors was a man with a high flight of thought. He has repeatedly spoken publicly on the development of alternative energy. In particular, he praised heat pumps, with the help of which, for example, in the Netherlands, residential buildings are almost massively heated. It was unbearable to listen to this Manilovism.

And it's not that the average January temperature in Amsterdam is about +5 and double glazing is not always installed there. It must be said frankly that alternative energy, even with the current high energy prices, is still unprofitable. Wind, tidal, solar and heat pumps exist only thanks to an extensive system of government subsidies. In Germany, about 7% of private households are heated with wood pellets instead of gas. The state subsidizes the purchase of a solid fuel boiler with automatic loading of pellets (its price reaches 10,000 euros), and also annually pays 50 euros in compensation for each kilowatt of boiler power. Without this, who would refuse gas?

Tell me, are you ready to install a heat pump in your country house for 20,000 euros? And to dig trenches for laying pipes 4 acres of a garden? That's it! However, one of the Dnepropetrovsk entrepreneurs installed such a pump in his country house.

I am very satisfied - at an expense of 3-4 kilowatt-hours, it heats 250 sq.m of area. And it can be understood - the electrical wiring in the village is weak, it will not withstand high current, and there is no gas pipeline and is not expected. It was cheaper to shell out for an imported contraption.

1. Insulation of external walls, windows, floor and ceiling

Gives a huge effect. If for heating a standard house in winter time approximately 1 kW of power per 10 sq.m is required, then after high-quality insulation this figure can be reduced by 1.5-3 times.

The cheaper and more profitable to heat the house with gas or electricity.

Example: three years ago, the author sheathed the walls of his garden house usable area of ​​76 sq.m with 100 mm foam sheets, installed metal-plastic windows, laid 50 mm extruded polystyrene foam under the floor, insulated the attic ceiling with a 250 mm layer mineral wool. In the end for heating season gas consumption does not exceed 1800-2000 cubic meters, which allows you to pay at the minimum rate of 0.7254 UAH / cubic meters. Monthly fee - 200-250 UAH. For an apartment of the same area, even at the old rates (at the entrance to the heat meter), you had to pay 550-600 UAH.

2. Programming the boiler

When you leave for work, it makes no sense to maintain +22 degrees in the house. If the building is well insulated, and it is not very cold outside, you can simply turn off the boiler. But it is better to get a regulator that will automatically provide a temperature of 15-18 degrees. Flowers and a cat will not freeze, but you are guaranteed to save 5-15% of gas.

3. Gas is the head of everything

If it is possible to set an individual gas heating there is no reasonable alternative to this option. Heating with firewood, coal or wood briquettes will cost at least 1.5 times more expensive, but trouble!.. Electricity at least triples the cost. The most expensive types of fuel are diesel fuel and liquefied gas in cylinders.

4. Air conditioning as a source of savings

Using an air conditioner (with the “winter-summer” function) in heating mode is not much more expensive than heating with gas, and compared to electric heaters, it is much cheaper! There is no violation of the laws of physics here. The air conditioner simply heats the house on the principle of a heat pump, taking heat from the outside air. The ratio of produced heat power to consumed can reach 3-3.5. True, this figure is lower, the colder it is outside. Therefore, it makes sense to turn on the air conditioner in heating mode at an “outboard” temperature of + 5-15 degrees.

On a note

Calorific value various kinds fuel

What is cheaper? Theory!

Moldova, Chisinau, str. M.Manole 5, tel (022 - 83 -53 -53) www.termostar.md, www.heiztechnik.md

What is cheaper in the country - bottled gas or electricity?

Gas heating or electric? The answer will be different for different types of houses.

The choice of the optimal type of heating determines not only the cost of maintaining the house, but also the level of comfort of living in it. When choosing a heat source for your home, you must make a calculation and do not forget that the system is installed for many years.

Important parameters for choosing a heat source

What is the best heating? The answer to this question will depend on what you choose as evaluation criteria, but three conditions are unconditional for any type of heating:

1. The amount of thermal energy must be sufficient to ensure the standard temperature in residential premises.
2. Start-up and operating costs should be kept to a minimum.
3. Heating should be easy and safe to maintain.

When choosing between gas and electric heating, it is necessary to take into account several important parameters:

• remoteness of the gas pipeline,
• the presence of the power supply network of the required capacity,
• dimensions of the heated room,
• heat loss through windows and walls.

Whatever heating system you choose, the main energy saving factor will be the thermal insulation of the room and right choice high performance radiators. Competent and comprehensive insulation of the house can reduce the consumption of the source of thermal energy by half. And if you purchased wholesale heating radiators the savings will be even greater.

Electrical heating systems

If your house is not gasified, then the most profitable option would be the installation of electric heating. The most common heating system is using a double-circuit electric boiler in unified system heating and hot water, when the coolant is heated by heating elements.

The heating system can be mounted with the installation of electric heating radiators, and in this case, electricity is converted into heat directly, without heat loss for heating water.

Advantages:

• electric boilers more convenient to maintain
• start-up costs vs. gas boiler an order of magnitude less
• ease of management and registration of permits,
• equipment compactness.

Flaws:

• the production of a unit of thermal energy using electricity is 8-10 times more expensive than gas,
• the need to install protective devices for the electrical network,
• the stability of domestic electrical networks is not very high.

When designing electrical networks, a certain power quota is allocated for each house building. And it may not be enough to connect your heating system on electricity. In this case, it is worth considering the option of combining an electric and gas source of thermal energy.

Gas heating systems

The best option for heating a private house in the presence of a main gas pipeline would be a gas boiler with a storage tank for hot water supply, a water heating system and a heat pump.

Advantages:

• initial investments pay off in 2-3 seasons due to lower energy prices,
• gas outages are much less common than power outages, so the stability of the heating system will be higher.

Flaws:

• higher initial investment compared to an electric boiler,
• high costs for permits and project documentation,
• the need for maintenance and control by special services,
• the need for gas supply and installation of a chimney,
• the bulkiness of the heating equipment,
• installation of a gas boiler is allowed only in a separate room.

It must be remembered that the calculation of economic efficiency always includes two main parts: one-time investments at the start and operating costs. And here the costs of electric and gas heating are diametrically opposed.

Choosing a heating system for different types of houses

Given the instability of work centralized systems heating, many apartment dwellers tend to switch to heating system. And in this case the best option will become electric heating due to the compactness of the heating equipment. In this case, there is no need to mount a powerful ventilation system, an ordinary hood is sufficient.

For country houses and cottages of a large area in the presence of a main gas pipeline the best choice will become a system gas heating. Moreover, in the villages Electricity of the net often not designed for increased load, so the arrangement of electric heating is simply impossible.

Heating wooden house gas boiler requires additional permits. Therefore, more and more homeowners are choosing electrical systems heating, giving preference to them for reasons fire safety, environmental friendliness, ease of installation and registration of permits.

Modern heating systems allow you to choose the most advantageous option for housing of any size, in apartment buildings and country houses. And by contacting the specialists of Vivaldo Radianjri, you are guaranteed to receive a highly efficient and safe heating system.

Comparison of gas and electric boiler

In Russia, electricity heating is much more expensive than natural gas heating, but how much? I will give an example of comparing the cost of heating a gas boiler and an electric one. To do this, I will calculate the cost of one kWh of the received thermal energy in both cases.

Gas boiler
Let's say the calorific value of gas is 38 MJ / m 3. Let's say the real efficiency (not marketing) of a gas boiler is 85%. Let's say the price of gas is 4500 rubles per 1000 m 3.

When burning 1000 m 3, we ideally get 38,000 MJ of energy. But taking into account the efficiency of the boiler, it is really 32300 MJ (38000 × 0.85).

1 kWh = 3.6 MJ, so 32300 MJ = 8972 kWh (32300 / 3.6).

Those. for 4500 rubles we get 8972 kWh, respectively, 1 kWh of thermal energy from a gas boiler costs 0.5015 rubles (4500 / 8972).

Electric boiler
Let's say the cost of electricity is 4.05 rubles per 1 kWh. Let's say the real efficiency of an electric boiler is 95%.

This means that the cost of 1 kWh of thermal energy from an electric boiler is 4.2631 rubles (4.05 / 0.95).

Comparison
So, we divide the obtained values:

4,2631 / 0,5015 = 8,5007

Those. electricity heating is 8.5 times more expensive than gas heating.
Of course, different regions have different tariffs for gas and electricity; the calorific value of the gas can also vary significantly.

What is the cheapest way to heat a house? Compare fuels and heating equipment

Accordingly, the difference in cost can vary both upwards and downwards.

Knowing the cost of 1 kWh of thermal energy and knowing the heat loss of the house during the heating period, you can determine how much money will be spent on heating.

For example, if, for example, the heat loss of a house is 30,000 kWh during the heating period, then the owner of the house will give 30,000 × 0.5015 = 15,045 rubles with a gas boiler, and 30,000 × 4.2631 = 127,893 rubles with an electric boiler.

It is also worth adding that there is a day / night tariff for electricity. In this case, electricity is cheaper at night, namely at night the lowest temperatures and the boiler consumes more energy. Therefore, taking into account this factor, heating with an electric boiler will be a little cheaper.

Today, when every six months there is an increase in tariffs for energy resources (electricity, gas), while the incomes of the population remain at the same level, the issue of saving energy consumption is acute. This problem is especially relevant in suburban housing, which, as a rule, has a larger area than apartments, and for heating country houses and dachas take a lot of money.

Old-fashioned wood and coal?

At first glance, it seems that it is more profitable to drown a private house firewood or coal, - says Olga. - However, having studied this type of heating in more detail, it is possible to identify the inconvenience that it causes. It turned out that a separate room is required for installation solid fuel boiler and a special place for storing firewood or coal, to finish building - again a waste. When burning wood and coal, soot, soot and coal dust are constantly formed, and there is always a risk of fire and carbon dioxide poisoning.

When heating with wood or coal, it is necessary to throw firewood or coal into the boiler several times a day, as well as clean the chimney and the equipment itself. If this is not done, the room cools down quickly. At permanent residence it will take several cubic meters of fuel per month to heat, this is unprofitable, add delivery to the cost of fuel - a tidy sum looms. Therefore, the woman came to the conclusion that heating with wood and coal is not cheaper than electricity, and even in comparison with gas, heaven and earth in general.

“And we have gas in our apartment!”

Yes, today gas is the cheapest source of heat energy in Russia, - Olga admits. - But the cost of work on summing up the equipment, obtaining permission to connect, again results in a pretty amount, which may not be affordable for people with low incomes. For example, they counted me about 600 thousand rubles for supplying gas to the house. And I have other expenses on my nose: repairs, moving, etc. Therefore, I dismissed this option as well.

Electricity is more profitable!

I saw only electric heating as an alternative, - continues the owner of the house with a stove. - Firstly, I found out that electric boilers are cheaper than gas boilers. And, according to neighbors, sometimes the money saved on gas equipment, can be enough to heat a house with electricity for several years. In addition, they explained to me that electric boilers are easier to connect, you don’t need to get permission to install them, you don’t need a separate room, and, importantly, they are safer. But electricity prices are higher than gas prices. The question arises: how to make electric heating profitable? Among the many proposals, I drew attention to Russian company"Koterm", which produces electric boilers popular among owners of summer cottages and private houses "Dachnik M1" and "Dachnik M5", about which I heard a lot from friends and neighbors in SNT.

I considered the offer profitable, since the cost of these boilers is low even for people with average incomes, and the manufacturer also offers with a guarantee to spend 30-40% less on electricity than other manufacturers of electric boilers, which makes it possible to live in the country during the cold months.

I turned to the specialists of the company and found out that these are electric heating boilers of a new type, which use a unique heating technology that can significantly save electricity.

What is the essence of the unique technology?

This article is designed for people who are used to counting their money. If in your garden you have diesel fuel from one well, and natural gas from another, the roof of the house is pasted solar panels and worth wind power generator then don't waste your precious time reading further. Many of us sooner or later decide in our lives to take such a serious step as building an individual country house. How simple it all sounds - “what should we build a house”, and how difficult it is in practice, because ceilings and walls are far from all that is necessary for comfortable living in it. The main task is to create comfort, and its main component, as you know, is the weather in the house. To do this, it is not enough to think carefully about the insulation of the house. It is necessary to choose and design the heating system correctly. The first thing to think about is which boiler to choose. Self-selection of options can take forever - tirelessly walking around companies, endlessly studying specialized literature, visiting various exhibitions, consulting with friends, and eventually getting lost in the endless forums of the World Wide Web. Therefore, it is better to entrust the choice of a specialized company. But you still need to know what you are buying and why. There are many options on the heating equipment market, but their number is significantly reduced if we have decided on the fuel on which our boiler will operate.

GAS

If there is gas, we can safely say that we are lucky. This is clearly illustrated by the calculation on the example of a specific boiler of the Italian manufacturer Lamborghini EXA 27 with a capacity of 30 kW. Its maximum gas consumption is 3 cubic meters. for a full hour of work. You should not take this figure and directly multiply it by the number of days in a year, because the boiler turns off and goes into standby mode when the set coolant temperature is reached. Subsequent switching on depends on how quickly the entire heating system cools down, i.e. from the heat losses of the house and the number of consumers (DHW, the "warm floor" system, swimming pool, etc.). As practice shows and thermal calculations premises where equipment of similar capacity is installed, the actual consumption of gas or other fuel is approximately one third of the maximum, i.e. in our case, the estimated figure is approximately determined by the value of 1 cubic meters per hour, per day - 24 cubic meters. Today, one cubic meter of natural gas costs about 2.9 rubles. (in the Moscow region), so in money equivalent expenses reach 69.6 rubles.

ELECTRICITY

But what if there is no gas? There are actually few options ... One of them is an electric boiler of the Czech company PROTERM "Skat" with a capacity of up to 30 kW. If the area of ​​​​the house does not exceed 300 sq.m and a voltage of 220 V is supplied to it, then it is quite possible to organize a heating system based on such an apparatus, especially since this technique has stepped far ahead today. Let's see what the costs are. For 1 kW in the Moscow region, you will have to pay 1.93 rubles. For a house with an area of ​​300 sq.m. a 30 kW boiler is required. thermal energy, which, with the same 33% consumption, “eats” about 240 kW in 24 hours, which in monetary terms will be 463 rubles. The advantages of such devices include flexibility in the settings of operating modes.

SOLID FUEL

There are also options with exotic elements - to heat with firewood, but not everyone likes to force themselves to run all night and throw up hard-chopped birch logs. If there is a desire to heat with coal, which has a high calorific value, then the neighbors are unlikely to appreciate it. The resulting stable smell near the railway station will give them considerable discomfort. This problem is successfully solved by installing a pellet boiler. When installing a modern pellet boiler (these are wood pellets made from waste associated with the wood processing industry, pulp and paper mills, etc.), for example, the Czech boiler Atmos D 30 P with a power of up to 29 kW. you will have to think about the fact that for the normal operation of the boiler, pellets, like any other fuel, must be of high quality, and such an apparatus will cost several times more than “competitors”.

LIQUID FUEL Today, many villages are gasified, and the issue of gas heating is a matter of time and certain family costs. At the first stage of construction, with restrictions on electricity, the option with a diesel boiler is most suitable for the house. The burners of the boiler are unpretentious, with proper maintenance and start-up they work without interruption for a long time. And when the gas is finally brought in, it will not be necessary to purchase a new boiler and dismantle the old one, it will be enough to change the burner from diesel to gas. Significant money savings will result. It is such a boiler that we will consider in more detail below. If we return to the calculation of fuel costs, then with diesel engines everything looks something like this. The consumption of an ECO 3 R burner from Lamborghini, set to 30 kW for a full hour, will be 2.6 kg. However, we already know that the boiler or burner goes into standby mode when the system heats up. Therefore, the average fuel consumption should not exceed 0.87 kg per hour, which is 1 liter. And if you count the money again, it turns out that with the cost of diesel fuel 21 rubles. per day we pay about 500 rubles. In conclusion, I would like to note. There are multifunctional boilers that can perform several tasks at the same time (heating several floors in different temperature conditions, floor heating, hot water supply, etc.) in a fully automatic mode. Maintaining the set temperature based on data received from sensors connected to the boiler automation, and installed both in the house and outside it. This allows you to achieve maximum comfort and coziness in the house, as well as saving fuel, and hence your money. Therefore, before buying equipment, decide what result you would like to get in the end. If you have any questions related to the choice of heating equipment, call and consult with our specialists.

There is a friend, the owner suburban area with a capital house with an area of ​​about 150 square meters. There is no gas nearby, and in the next five years (or even further) it is not expected. Now the house is heated by electricity from time to time (arrived - turned on the heating, left - turned it off), because of this, the decoration has come to a completely indecent state. In the coming winter, a friend is going to move into this house for permanent residence, since it is close to the city, the dacha array adjoins the neighboring village almost closely, that is, there are no problems with uncleaned roads.
The question of heating arose, the owner wants a wood-burning boiler of the type " long burning", and I strongly recommend autonomous gas supply to him. This is how we got the dispute "traditions against technologies."

Is there a reasoned opinion on this? I propose to discuss.

Only, please, right away - I'm interested in the specifically indicated options - firewood and LPG, get rid of the "projections" of thermoelectric modules and other "windmills", the question is purely practical.

How to heat the house with wood or gas is up to you, of course, to decide!!!
Once upon a time, they wrote in large letters: "THE ECONOMY SHOULD BE ECONOMIC"
And here, too, it is necessary to estimate and weigh, well, at least gas heating ...
There is such data ... that the consumption of liquefied balloon gas (propane 50l) for heating a house with an area of ​​​​150 m2 is 168 cylinders and with permanent residence the costs will be 102,000 rubles. in year!!!
It is also indicated that the cost can be reduced to 30% using a chronothermostat, that is, the costs will be 102,000 * 0.7 = 71,400 rubles. in year.

And now we believe that heating in an apartment with an area of ​​​​30 m2 costs 2000 rubles. per month, and for the year 24,000 rubles.
If we compare the areas, then the house is equivalent to five apartments and the total heating costs of which will be 24,000 * 5 = 120,000 rubles. in year.

It turns out, in the first approximation, that, in general, such a house can be warmed with gas ...

But is there an ALTERNATIVE??? and something else!!! Let's take a look at the firewood!!!

Wood or LPG? Tradition vs technology.

Depending on which region. If Ussuriysk or taiga - of course firewood, if Ukraine - coal. If the house is on the coast of the sea - a Joule stirrer. It is up to your friend to decide, of course, but purely for aesthetic reasons, I would choose firewood, build a fireplace for myself, put on a long-burning boiler and be like that. There is just a lot of forest in our region, so there is such a topic.

Yeah ... Rikota did not specify the region ??? And yet, how to heat firewood and throw logs at night and also put a spark-extinguishing grid 5 by 5 mm ??? Or hire a stoker in the house ... He rests during the day, and fires at night !!! ... or ... well, at least make one firebox in two days ...

I think that with firewood there are also real good offers ...

Wood or LPG? Tradition vs technology.

The region is the Volga region, the winter temperature of the coldest five-day period is minus 30, the average for the heating season is minus 5.5. Duration heating period about 210 days or so. Firewood and liquefied gas are equally available.

I don’t like pointless conversations, let’s have a reasoned conversation.

Let's start with capital costs.
Installation of a gas tank with a volume of 4.8 cubic meters. will cost about 300 thousand rubles (180 - equipment plus 120 - installation and commissioning).

Wood or LPG? Tradition vs technology.

I think it's worth finishing on the first point.

And if there is a second one - liquefied gas + delivery at a price of 11 rubles / liter, so count how much it will turn out. In any case, if the Volga region, then firewood, a fishing line region (the middle lane where I live). We have woodworking waste lying around the city.
And so it’s good to consider if, then you need to take the specific calorific value of the fuel per kilogram of mass.

Wood or LPG? Tradition vs technology.

Okay...
You, Rikota, didn’t say anything about firewood, it was casual, but immediately grabbed the gas ...
Biased... Gas us!!! Go...

We start with a gas tank ... We save 70 tr. and buy our native used for 230 tr. ... and our veteran will serve another 50 years!!!
Underground tank.
Volume 4800 l.
LPG filling - 1.15 tons.
Weight 2200 kg.
Autonomous turnkey gasification using a used gas tank: 230,000 rubles.
This amount includes:
Delivery of a used gas tank to the installation site within 100 km;
All necessary earthworks;
Concrete base for installing a gas tank;
Second-hand gas tank installation;
Laying a gas pipeline from the gas tank to the house (within 10 meters);
Conducting an intra-house gas main to the consumer (boiler, water heater);
Setup and commissioning.

It seems to have reached the boiler??? And what about the boiler? It doesn't exist yet!!! No boiler room either! There is no thermal characteristic of the house either !!!
It is unlikely that according to SNiP it will be cozy and good ???
So come on, Rikota, and what is your opinion on this matter ??? Not a house of cards for 150 squares???

Wood or LPG? Tradition vs technology.

Yes, in any case, gas is more expensive, whatever one may say. It is necessary to be ready to immediately pay for heating for 20 years in advance. And who knows what else will be there in 20 years! I don't think a lot of people would want to install something like this. The only serious plus of this gas tank is the autonomy of work, turn it on and forget it. No need to carry firewood, no need to heat, everything works by itself.

Wood or LPG? Tradition vs technology.

And then immediately there are questions about both wood and gas ??? Yes, in any case, gas is more expensive, whatever one may say. Let's spin??? Rikota is asking for exactly that!!! Please count!!!
Yes, and you too...
"And it's good to consider if, then you need to take the specific calorific value of the fuel per kilogram of mass," Sergey said. What's stopping you???
As far as I know, the calorific value of 1 m3 of methane is 34 mJ/m3. etc. And not only will she be able to do this ... She can even convert this amount of heat into power, both theoretical and EVEN practical ...
For firewood, carrying out the same operation with a calorific value of 1 m3 of firewood will not present any difficulty for you, Sergey ...
After that, you can talk about firewood on the numbers ...
Do you have any questions about gas to Rikota??? But she's not there yet... She'll come... we'll talk...

The calorific value of methane is of no use to us here, in the topic the option "natural gas" is not even considered, it is simply not available.
The calorific value of liquefied gas (plus or minus, depending on the supplier and composition of the gas) is 46.8 MJ / kg at a cost of 16.5 rubles / liter or 30.5 rubles / kg, firewood (well, some average, say , birch) - 15.0 MJ/kg at a cost of 3 rubles/kg.

Simple arithmetic calculations and here you are: liquefied gas - 1 MJ for 0.7 rubles, for wood - 1 MJ for 0.2 rubles. Let's translate this into "publicly available" kilowatts and get 2.35 rubles / kW for LPG, 0.71 rubles / kW for firewood.

Energy prices are steadily rising, so an increasing number of suburban residents are thinking about how to heat their homes inexpensively and efficiently. Most often, homeowners are concerned about what options are available for heating a private house and country house, which boiler has the highest efficiency, which boiler to choose for the heating system, how to install the heating system correctly, what types of heating exist without gas and which of them are the most economical.

FORUMHOUSE advises a different approach. First, we determine the type of fuel, and already “under it” we select a heating system.

From our material you will learn:

• What are the costs of a heating system?
• What type of fuel can be called the most affordable;
• What means convenient system heating;
• Can heating with electricity be cheap;
• What can become the basis of an economical heating system.

What are the costs of a heating system?

How much a particular heating method will cost depends on many factors. Only by calculating all the costs (it is also necessary to take into account the increase in fuel prices in the long term), you can decide on the most cost-effective heating method. For this it is necessary to take into account:

• fuel cost;
• the cost of its delivery;
• The cost of heating equipment;
• The cost of its installation;
• The cost of its operation;

• The average monthly air temperature in winter period time;
• Way of living in the house: mode "cottage" or permanent residence;
• Availability of communications connected to the site (gas, required electrical power);
• The degree of insulation and energy efficiency of the home.

Thinking about choosing a heating system and considering different variants heating in the house, first of all, you need to answer yourself the question: not “how”, but “what” will you heat your home. Expenses for the heating season depend on the type of fuel, its cost and availability.

Consider the following situation: the main gas as a more economical favorable view fuel is not available at the moment, or its connection will cost too much. What to do in this situation, what type of fuel to choose: firewood, liquefied gas, coal, pellets, fuel briquettes, electricity, even - there are a lot of options. Let's see which type of energy carrier will be the most preferable.

Conclusions:

• It will be correct to choose a heating system after a competent calculation. This is the only way to achieve a balance between efficiency, economy and convenience;
• Vacation home it is necessary to insulate well, to reduce all heat losses to a minimum, otherwise the lion's share of the energy will go to heat the "street";
• Approximately, the required power of heating equipment is calculated by the formula: 1 kW of energy is required to heat 10 sq.m of the house area;
• The efficiency of the heating system largely depends on the availability of a particular type of fuel;
• To get the maximum effect, you need to combine different types heating systems and energy carriers. It cannot be said that if these conditions are met, we will get heating cheaper than gas, but we will be able to save significantly.
