On the map of our homeland there are places where gas supply is not available. In this case, alternative heat sources are used. What are the ways and options for heating a country house without gas?

Furnaces

Wood and coal are an efficient heating method for rural areas. They have long been used to heat village houses. The advantages of the option are affordable raw materials at low prices. Disadvantages - the need to regularly maintain the fire, free space for storing firewood, the need to purchase and install a stove, boiler, and other consumables.

Electric heating

Electric heating has a number of advantages and disadvantages. Economical heating of a private house without gas is possible only with proper design and installation of equipment.

Note. To determine how effective the technology is for a particular facility, it is necessary to carry out preliminary calculations of heating and resource consumption in accordance with SNiP standards.

The advantages of the method include: minimal costs for installing appliances, no chimney and boiler room are needed. When heating rooms in this way, carbon monoxide is not formed, there is no risk of harmful emissions if the system breaks down. Despite all the advantages of the technology, it cannot be said that the method is the best way to heat a house without gas.

What is known about the cons. Electricity costs vary by region. The option may not be economically viable. An important drawback is the complete dependence on power sources. When the electricity goes out, the system stops heating the house.

Alternative energy sources

Heat pump

The equipment allows to receive low-grade heat from air, soil, rocks and reservoirs. The technology has been used in Europe for decades.

The advantages of the option are free heat sources. The use of technology allows to reduce heating costs. For every 2-3 kW of electricity spent on the operation of a heat pump, up to 6 kW of thermal energy is released. Savings are especially relevant, with the regular increase in tariffs, which is observed in the housing and communal services industry.

And yet, it cannot be said that this is the best option for how to heat a house without gas and electricity. An important drawback of the technology is the high cost of equipment. The cost of a heat pump is from 100 to 400 thousand rubles. Another unpleasant feature of the equipment is a decrease in efficiency at temperatures below -10º C. In addition, the area for feeding the equipment cannot be planted with plants, and its area must be several times larger than the size of the building itself.

Solar collectors

The equipment works autonomously. This is a big advantage over dependent technologies. The collector converts solar energy into thermal energy. This is one of the best ways to heat your home cheaply without gas. During the operation of the equipment you will not have to pay.

Cons of technology

1. high cost of the collector $500-1000;
2. water heating only up to 60º C;
3. periodic replacement of the storage tank;
4. failure to provide 100% heat.

Note. A complete transition to heating a house without gas and electricity using a collector is impossible. The equipment is used as an additional source of heat to reduce heating costs by 40-60%. With the onset of cold weather or in windy weather, you will additionally need a water pump to disperse the water in the pipes. When the climate worsens, the collector stops working at full capacity.

Water heating

Popular technology allows you to effectively heat the premises of a private house. Are you considering how to heat a house if there is no gas? Take a look at hot water. Heating bills can turn out to be small, however, you will have to spend money on installing equipment, pipes, batteries, a tank, a pump. The technology allows the use of several energy sources:

The disadvantage of panels is expensive fuel (electricity).

How to save on heating?

A simple solution will significantly reduce heat loss. We are talking about high-quality insulation of walls, door blocks and window openings. This will reduce heat costs by up to 50%.

Of all the ways to heat a house, the most economical is gas. In places where there are no appropriate communications, other options are chosen. By clicking on it, readers will find out how cheaper and more profitable it is to heat a house with gas or electricity. Today it is economical to heat cottages with coal. Fuel is available. It is inexpensive. There are automated coal-fired equipment for sale. Its price is 1.5-2 times cheaper than heat generators.

What is the best way to heat a house if there is no gas? If the room is used as temporary housing, on short visits, a heater can be used. Among the well-known models, oil specimens are more often chosen. A fairly economical and safe option is an infrared heater. The method is suitable for heating one room, not the whole house.

- ranging from solid fuel boilers for home heating and ending with heat pumps. Most homeowners believe that it is profitable to heat the house with a gas boiler, but FORUMHOUSE users know that under certain conditions this is far from the most optimal solution.

Due to the constant rise in energy prices and the high cost of connection, many developers are concerned about the following issues.

• Is there an alternative to the main gas;
• What features can different heating systems have;
• How to calculate the price of a particular type of fuel;
• Is it profitable to use solid fuel heating systems;
• How to heat a house with electricity and not go broke;
• Can a home heat pump replace traditional heating systems.

And experts and users of our forum will help you find answers to these questions!

The main criteria for choosing a heating system

Construction experience suggests that autonomous heating of a private house is selected taking into account many factors: the degree of availability of a particular type of fuel, the estimated monthly heating costs, climatic living conditions and building heat loss.

Heating a house in a temperate climate is one task, and completely different requirements are placed on the heating system in regions with an even colder climate than in Moscow and a months-long heating season.

The efficiency of the heating system at home depends not onlyon the thermal characteristics of the fuel and the efficiency of the boiler, but also on the design features of the house and the degree of its heat loss.

A poorly insulated dwelling nullifies the work of the most highly efficient heating system!

Therefore, the choice of a heating system and boiler equipment must begin at the design stage of your future home. Any of the experienced developers will agree with the statement that there are no trifles here, and any mistake or flaw can lead to costly rework.

First of all, let's consider .

Alexander KhadynskyHead of the heating systems department of the company "My fireplace"

The choice of heating system, first of all, depends on what communications are connected to the house. If the main gas is already connected, then the choice of fuel usually ends there, because. at the moment, heating the house due to main gas is recognized as the best solution.

It is also worth considering the convenience of operating the heating system in different modes of residence: daily, weekend mode, one-time visits. Only after weighing all the pros and cons, you can choose the best option.

In the absence of main gas, the process of heating the house on the so-called gas tank is possible - a sealed container buried on the site and in need of periodic refueling.

The advantages of liquefied gas, as well as main gas, are clean exhaust, the ability to install compact chimneys and small boilers for heating poison.

With all the advantages, this system of autonomous heating of the house has a number of disadvantages.

Anatoly Gurin CEO of DoM Engineering Systems

The main disadvantages of a gas tank include: expensive installation, inconvenience of refueling, obtaining permits, and the need for periodic maintenance by highly qualified personnel. In addition, the gas tank takes up a lot of space on the site.

Igor Larin Head of "Boiler Equipment" WIRBEL

The choice of fuel, and hence the boiler equipment, depends on the degree of its availability in a particular region. If the house has main natural gas, then the choice is obvious in its favor, if not, then it is necessary to assess the cost and availability of other types of fuel for heating in the area, and install equipment accordingly.

How to replace gas

The advantages of gas are well known, but all of them are offset by the extremely high price of supplying it. Let's consider alternatives.

Liquid fuel

Diesel heating – requires the installation of expensive and complex equipment.

It is necessary to find a place to install a fuel tank. Diesel fuel has a peculiar and not for everyone pleasant smell. Also, due to the constant increase in prices for hydrocarbon fuels, heating with diesel fuel is one of the most expensive ways to heat a house. Among the main advantages for this type of home heating, a high degree of automation of the boiler and the ubiquity of diesel fuel can be distinguished.

Electricity

Electric boilers are easy to operate, environmentally friendly, safe and silent.

Alexander Khadynsky

However, with low initial costs for the purchase of equipment, it is very expensive to heat with electricity, and during power outages, you can be left without heating and without hot water. Also, an electric boiler for heating a house will need to install separate wiring, and if its power exceeds 9 kW, a three-phase network of 380 V.

In addition to electric boilers, there are such heating devices as electric convectors and infrared emitters.

The advantages of heating with electric convectors and infrared emitters include minimal initial costs and ease of equipment installation. You do not have to deal with the arrangement of the boiler room or conduct heating pipes. It would seem that he took the device out of the box, plugged it into the network and use it. But, as practice shows, not everything is so simple.

Oleg Dunaev civil engineer

A well-insulated house can be successfully heated with an electric convector only if there is sufficient electrical power.

• high equipment efficiency;
• ease of installation;
• presentable appearance;
• safety of use;
• the ability to program energy-saving modes.

The cons include:

• additional costs for high-quality wiring;
• increased requirements for the quality of power supply elements.

Unlike an electric boiler, installing a convector or any model of an IR emitter does not require laying pipes and the presence of a heat carrier, as a result, inefficient energy costs for heating water (coolant), boiler and pipes are reduced, and heat losses are reduced.

Here are the main criteria for choosing such a heating system.

Oleg Dunaev :

- We choose this way: the power of one convector is up to 1.5 kW (more - the plugs melt and the relay contacts burn).

The programmer has its own power supply (settings are saved when the power is turned off). For 10 sq.m. area requires approximately 1 kW of convector power.

Electricity - 380V, 3 phases, permitted power - at least 15 kW. Wiring section - 3x2.5 sq. Mm. We lay dedicated converter lines and connect no more than three convectors to one line.

A wall-mounted electric convector is best hung under a window about 15 cm from the floor.

Heating with electricity is one of the most expensive ways to heat a home. It would seem that cheap heating with electricity is a myth. However, a user of our forum Alexander Fedortsov(nickname on the forum Skeptic ) refutes this assertion by its own example.

Skeptic Forumhouse User

I independently built a well-insulated frame house on the foundation of the UWB. First, according to the project for heating a house with an area of ​​186 sq.m. a solid fuel boiler was supposed. After a little thought, I decided that I didn’t want to become a stoker at all, but it was better to use the night tariff and heat water in a reliable home-made heat accumulator with a volume of 1.7 cubic meters.

Water heated overnight by electric heating elements up to 50 C, allows you to successfully heat the house in the winter months with a water heated floor system. You can monitor the temperature with a custom controller.

Alexander Fedortsov

I put the floor heating unit in the boiler room on a sheet of foam plastic of 35 density and 10 cm thick. The heat accumulator is well insulated - 20 cm of stone wool on the tank lid, on the walls - 15 cm. .rubles In January, they wound up no more than 2 thousand rubles. T

solid fuel

Firewood, coal, fuel briquettes.

Alexander Khadynsky

A solid fuel boiler (coal, firewood) requires constant attention, practically turning its owner into a stoker. Such structures can be used in places where neither gas nor electricity is supplied. They are the most affordable and are the cheapest. When using solid fuel boilers, it is especially important to observe fire safety measures.

Igor Larin

The degree of autonomy of solid fuel boilers can be increased by using a buffer tank - a heat accumulator in the system. Thanks to TA, heat is accumulated and the number of bookmarks in the boiler is reduced.

On average, the operating time of a solid fuel boiler on one tab is at least 3 hours, maximum 12 or more hours. The temperature regulator controls the air supply to the combustion chamber, and overheating protection is provided by a special valve and overheating protection heat exchanger.

When using solid fuels, there is no need to communicate with supply companies and obtain permits for installing a boiler. Everything is regulated by SNiPs, which must be followed during the installation of heating equipment. You should also follow the manufacturer's recommendations for fire safety.

As a backup heating system in case of a power outage, it makes sense to install a multi-fuel boiler or combine several heaters.

Alexander Khadynsky

An additional boiler is often used to increase the degree of automation of a solid fuel boiler, an electric boiler or a fireplace with a water circuit are connected to the circuit.

Autonomous heating in a private house through combined boiler rooms is an expensive option. These types of boilers combine three types of boilers at once - solid fuel, electric with a gas or diesel burner and are the most expensive of household boilers. In the event of a power outage, it is better to connect an uninterruptible power supply, which will allow the equipment to continue operating for up to 48 hours during the power outage.

Igor Larin

It is possible and even necessary to combine different devices for space heating, especially in regions where fuel shortages are possible.

Practical are systems where solid fuel boilers are combined with wood-burning fireplaces, i.e. the system includes an additional heat generator (fireplace), which supports or accelerates the heating of the system.

The benefit of using multi-fuel boilers is the ability to combine two types of fuel in the same equipment. In a boiler with two furnaces, solid fuel (wood, coal, briquettes) can be burned in one, and a burner (diesel or pellet) can be installed in the other. Thus, the homeowner, depending on the situation, can choose the type of heating that is convenient for him.

Anatoly Gurin :

- The undoubted advantages of pellet heating include: autonomy, its low cost relative to electricity and diesel fuel with propane. Among the minuses, it can be noted that it is necessary to find a place for storing pellets.

And low-quality pellets, due to incomplete combustion, reduce the efficiency of the boiler.

The boiler itself requires weekly attention, because. it is necessary to clean the burner and fill the pellets.

The time of continuous operation of the boiler can be significantly increased by installing an additional bunker for pellets.

In recent years, it has become more and more popular alternative heating systems houses built on heat pump etc. (see diagram).

Anatoly Gurin :

– The principle of operation is simple: the heat pump transfers warm air from the street to the house. The easiest way to imagine a heat pump is like a refrigerator: the freezer is in the ground, and the radiator is in the house.

The experience of using such a heating system shows that, having spent only 1 kW of electricity, we get 5 kW of heat.

Despite the fact that such a heating system has been known for decades, many are stopped by the high initial costs required for its installation.

A heating system is a long-term investment in your home, and lower initial costs are further offset by higher fuel and boiler maintenance costs.

Benefits of using a heat pump:

• low, 5 times less than when heating a house with electricity, ;
• when air circulates from the street to the house, there are no emissions;
• the system does not require maintenance;
• autonomy of operation: the heat pump requires only electricity, and in the event of a power outage, the heat pump can be easily powered from a gas generator.

How to understand what is more profitable to heat a house

The cost of heating consists of the cost of fuel. There is no universal fuel that is equally suitable for every region or home. Therefore, it is necessary to make a calculation based on the specific situation.

Igor Larin

When choosing a fuel, one should not be guided only by momentary profit, it is necessary to focus on the long term.

There is no gas and there will not be, but there are woodworking enterprises around, respectively, there will be (or already are) pellet manufacturers. In this case, an effective solution would be to install a solid fuel boiler, which can later be turned into a pellet one (by installing a pellet burner in the bottom door).

There may also be a situation when gas should be carried out in 1-2 years. At this time, you can put a solid fuel boiler and then install a gas burner in it.

Anatoly Gurin

It is necessary to choose the cheapest fuel in the region. It will be most profitable for them to heat the house. For an objective calculation, it is best to compile a summary table that displays the types of heat sources available, their construction costs, operating costs and service life.

In the long term, it is important to take into account such a factor as the convenience of using a heat source. Experience shows that no matter how cheap fuel is, its low price can be crossed out by the minimum degree of autonomy of the boiler and an increased degree of attention to the operation of this equipment.

Alexander Khadynsky

It is necessary to conduct a brief analysis of the most probable methods of heating with one or another type of fuel.

Knowing the power of the boiler, you can calculate the cost of heating costs per month. Approximate calculation - 1 kW is needed to heat 10 sq.m. (provided that the distance from floor to ceiling is up to - 3 m), in addition, you need to take a margin of 15-20%, which is necessary for preparing hot water.

On average, boiler equipment operates for about 10 hours / day. The heating season in central Russia lasts 7-8 months a year, the rest of the time the boiler works to prepare hot water and maintain a minimum temperature of + 8C in the house.

Total:

Electricity: Approximately 1 kWh of electricity is consumed to produce 1 kWh of thermal energy.

Solid fuel: Approximately 0.4 kg/hour of firewood is consumed to obtain 1 kW/h of thermal energy.

Diesel fuel: Approximately 0.1 liter of diesel fuel is consumed to obtain 1 kWh of thermal energy.

Gas: Approximately 0.1 kg of liquefied gas is consumed to produce 1 kWh of thermal energy.

In the long term, it is necessary to take into account the increase in fuel prices, based on the trends of recent years, and the payback period for the initial investment.

In this way, the choice of a heating system consists of a whole range of measures and engineering solutions that require a balanced approach and a thorough analysis of each specific situation.

Watch videos about the unusual layout of the heating system and how to organize efficient and cheap heating with electricity on your own.

Along with the classic central heating, people are increasingly using alternative methods of heating their homes. This is especially true for private households. The owners of such houses can choose the cheapest heating available in their region of residence. But in order to understand which type to give preference to, you need to conduct a simple analysis.

Show all

Types of heating

Heating is the process of heating the surrounding air or surfaces, which raises the temperature in the room. To obtain heat, various kinds of energy are used, which are further converted into heat. There are three ways to organize home heating:

• centralized;
• autonomous;
• individual.

In the first case, the classical method is used, when heating radiators (batteries) are installed in the rooms. Hot water circulates through them, supplied through branched pipelines. This coolant is produced outside the home, and the price for its use is calculated not in the cost of energy conversion, but in the actual heat sent to the consumer.

Since the heating companies involved in the supply of coolant are trying to save money, almost all heating networks are in a deplorable state. Because of this, the losses only during the passage of heated water through the pipes are about thirty percent. For example, in Europe this figure does not exceed two percent. Therefore, often the battery heating temperature is insufficient to achieve comfortable conditions. In addition, the consumer cannot influence the switching on and off of heating in any way, not to mention self-regulation of the temperature. At the same time, due to wear and tear of the equipment, frequent interruptions are also possible.

Autonomous heating involves finding a source of thermal energy in a special building made on the territory of the house management. This place is called the boiler room. The advantage of this approach is the absence of operating costs, stable and regulated heat supply. But the initial start-up of this system is associated with high costs, therefore, a complete shutdown of the boiler house is not done, even at the end of the heating season. In this case, the cost of heating depends on the type of fuel used and the required power of the entire system. Therefore, it is important to choose the cheapest fuel for heating correctly.

The source of individual heating is located directly in the room that needs to be heated. This type is characterized by simplicity and precise temperature control. But its disadvantages include self-repair of the system in case of its failure. The emergence of dependence on suppliers of transformable energy into heat, for example, gas, electricity.

Used energy resources

To obtain heat, in addition to equipment that will accumulate and give it away, energy is needed. Its source can be substances that have a high energy potential, that is, a parameter characterizing their expediency of use. Its unit of measurement is usually expressed in joules (J) or kilowatt-hours (kW / h).

All existing resources are divided into two classes: primary and secondary. Natural processes are involved in the origin of the former: thermal waters, minerals, sunlight, wind. The latter are by-products of human activities: waste, emissions of combustible gases.

Primary resources are conditionally divided into renewable, inexhaustible and limited. Renewable energy includes energy derived from sunlight, plant products (wood), the movement of water and air. Thermal waters and substances releasing thermonuclear energy are considered inexhaustible. But the most widespread is the use of natural resources, the supply of which is limited. These are substances such as coal, oil, gas, peat, shale, as well as uranium and thorium.

Since these resources will ever run out, their use becomes more expensive every year. Therefore, technologies are developing aimed at the use of practically unlimited energy, and more and more new devices are being invented to use it.

Solving the problem of choosing the cheapest type of heating for a private house, people, although rarely, prefer alternative energy sources. In particular, the use of solar panels and collectors, wind turbines, biogas devices, heat pumps. Building a heating system using alternative energy sources is a rather expensive process, but over time, due to the almost free energy production, the installation costs pay off. The average period is about ten years.

Previously, it was impossible for residents of multi-storey buildings to refuse centralized heating, but now such an opportunity has appeared, so the choice of a profitable heating method has become relevant for them as well. Although for residents of high-rise buildings, in comparison with people living in the private sector, not all options are available.

What is cheaper to heat a country house?



Heat producing devices

Modern manufacturers in the field of heat engineering can offer the consumer a wide selection of heating devices. The proposed equipment differs both in the type of energy source used and in power. For private use, this can be a budget device that allows you to heat a small room or an expensive one, but designed for autonomous heating of a large house. But despite this, There are three classic types of equipment that use as a source of energy:



Each type of equipment has its own advantages and disadvantages. For one type, the cost of consumed resources will be low, but the purchase and installation of equipment will be very expensive, and for the other, the opposite is true. Therefore, in order to find out what will be the most economical heating for a country house or apartment, you will need to take into account not only the cost of resources, but also the costs of installing, adjusting and maintaining heating devices.

When choosing the cheapest heating for a summer residence, a private house or an apartment, it is necessary to stick to a single average indicator, since buildings can be made of different building materials and located in different climatic zones. Therefore, it makes sense to consider financial costs as the cost of one kilowatt per square meter of surface.

The best heating system for a private house!



gas boilers

For gas heating, appliances are used that allow burning gas. As a result of this process, thermal energy is generated, which is transferred to the coolant (water). This water circulates through a closed pipeline system, giving off its heat to the radiator structures, and they already heat the air in the room.




Gas boilers differ in their principle of operation, which affects the coefficient of performance (COP). So, in mid-2018, the average cost of gas in the country amounted to 6.63 rubles per cubic meter. Respectively, the cost of heating using gas per 1 kW will be:

The most interesting is the condensing type. Such boilers are more economical than classical designs due to the use of the heat of condensation of water vapor and the shape of the burner. The cheapest such boiler will cost about 60 thousand rubles. About 4 thousand rubles will cost its installation and the same amount of work on setting up the system. In addition to the boiler, you will need to purchase pipes, radiators, all kinds of fittings, as well as draft a heating system installation and obtain permits.

Heating a country house with wood

Electric tanks

The principle of operation of such a boiler is based on the use of tubular electric heating elements (TEH) or the passage of electric current through water located between two electrodes. Heating electric boilers are mini-boiler rooms. Their design includes a circulation pump, an expansion barrel, an automation system. The cost of electricity on average is 3.1 rubles per kilowatt. At the same time, the tariff can be cheaper if you use the boiler only during grace hours (from 23-00 to 7-00), but this will require a two-tariff day-night electricity meter.

The efficiency of electric boilers is quite high and averages 98-99 percent. In this way, costs will be approximately:

It is believed that for every ten square meters the boiler needs to spend one kilowatt of its power.

That is, if it is necessary to warm up a dwelling with an area of ​​​​one hundred square meters, while the boiler will work for about six hours a day, 60 kW / h will be needed, and 1860 kW per month. But, as practice shows, the average cost for the heating season in the cold winter is about 10 thousand rubles.




Electric boilers are divided into wall and floor. For the former, the power ranges from 5 to 60 kW, and for the latter, it is more than 60 kW. In addition, electric boilers differ in the type of coolant circulation. It can be natural or forced. The purchase of a boiler will cost about 7 thousand rubles, another 4 thousand will cost its installation and connection. In some cases, you will have to change the wiring to provide the boiler with the necessary power.

solid fuel

Solid fuel devices, although they have made a technological breakthrough recently, their efficiency still does not exceed seventy percent on average. Wood, coal, pellets are used as fuel. Loading of a fire chamber can occur in the automatic mode or manual. In the case of using automation, electricity costs can be ignored.

The cost of heating will look like this:

The principle of operation of the boiler is based on the transfer of heat generated during the combustion of fuel in the furnace of the device, a water jacket that communicates with the heating system circuit. The price of the cheapest modern solid fuel boiler is 40 rubles, its adjustment costs about 3 thousand. To equip the heating system, you will also need batteries, pipes, a chimney, a place for storing fuel.




Alternative sources

Building systems on alternative sources allows you to really get cheap heat with your own hands. Such systems are built on solar panels or collectors. The use of photocells makes it possible to achieve an efficiency of about fifteen percent. The resulting energy is converted into electricity, which can be used to heat water or connect thermal appliances.

Solar collectors consist of a black metal plate placed under a layer of water. The plate transfers heat to the water. If the circuit is placed in a tank and cold water is connected, then the liquid will begin to circulate through the circuit using a pump.



Wind generators also allow you to get inexpensive heating due to the rotation of the propeller. When it rotates from the wind, an EMF is induced on the generator. After the generator, the voltage is supplied to the transformer, where it rises to the desired value and is given to the power grid.

The heat pump works on the Carnot principle. This is a complex high-tech device. It collects external heat and transforms it into internal. The value of its efficiency is much greater than unity. For example, if the device consumes 1 kW, then at the output it will be able to produce about 4.5 kW of thermal power.

Alternative sources look attractive, but in order for their power to be enough for heating, you will need to make a rather impressive initial cash investment. For example, a system of solar panels will cost about half a million rubles.

How to make cheap heating of a private house?

System selection

Thus, it is possible to heat a house cheaply in several ways. The most economical ways are to use inexhaustible energy. But due to the cost of devices, their use has not yet received sufficient popularity. That's why according to the type of resources used, the heating systems are arranged in the following order:



Using solid fuel boilers, it will be possible to heat with coal, wood or other solid fuels. Pellets are used to automate the process. But a rather significant drawback of this heating method is the need to find a place to store fuel.

If gas is supplied to a private household, then heating with it will also be a good option. But the inconvenience will cause obtaining permits for the establishment of such a system. Electric heating of large areas will not bring significant savings. due to high energy consumption. Its only advantage will be the ease of installation, which does not even require a connection to the chimney.

Many would like to buy housing outside the city. However, when building a private house, various problems arise. One of them is how to heat a country house. Most often, there is no possibility to connect to the central heating on the land plot. So, you have to think about what type of autonomous heating to use.

Ten years ago, every owner of the house tried to connect to the gas supply in order to heat the room with gas. Now the situation has changed. There are alternative ways to heat the building. Constantly rising prices for the usual coolants. Space heating costs have not only increased, they have increased exponentially.

Modern owners are armed with both the old "grandfather" and the most advanced heating technologies.

After the end of the heating season, the owners of private houses calculate the cost of heating the house. Many people think about how to change the heating system, because there is an alternative. We will describe several options for heating private buildings.

Stove heating with wood

If the house is built away from gas mains or you do not want to pay for an expensive coolant, you can arrange a heating system with wood. This option is ideal from an environmental point of view and does not harm the health of residents. How does a wood burning stove work?

The principle of operation of this design is simple and clear. You buy a stove, put firewood in it, set it on fire. Firewood burns and heats the stove equipment. The stove gives off heat, the air in the room warms up.

Despite the apparent primitiveness of the design, this heating option has a number of advantages:

• the oven heats up quickly;
• there is no need to buy and install pipes, radiators, pumps;
• the design is reliable, designed for long-term operation, it is difficult to damage it;
• firewood can be purchased cheaply.

Modern heating stoves bear little resemblance to well-known potbelly stoves. The design of the furnace is designed so that the installation gives off a lot of heat and can work for a long time from one load.

The structure of the boiler for firewood.

A boiler can be built into the wood-burning heating system. When choosing a boiler, it is better to dwell on a pyrolysis type design. Heat will be generated as a result of combustion of pyrolysis gases. This type of boiler equipment can function without electricity.

How does a solid fuel boiler work? At high temperature and in the absence of oxygen, the burning fuel decomposes into generator gas and solid waste. In this case, it is possible to achieve maximum heat transfer from fuel combustion.

Now about the disadvantages of this type of building heating:

• the furnace installation is quite large, you have to think about where to install it; the equipment weighs decently, so you won’t be able to install the oven yourself;
• next to the house it will be necessary to provide a covered room for firewood, it is important that the wood supply is enough for the heating season;
• combustion products from improper operation of the furnace device can be hazardous to health;
• when heating with wood, it will be necessary to provide for a chimney device;
• the stove will heat the room unevenly.

With the help of coal

Many private houses are located far from the gas pipe. Buying firewood in some regions is more difficult than coal. You can purchase equipment that runs on solid fuels. Boilers designed to burn coal have sensors to control the heating temperature. The use of coal will reduce the amount of harmful substances that appear as a result of combustion.

When choosing firewood or coal, you should decide in advance where and at what prices you will buy fuel.

Boilers for solid fuels consist of a furnace in which the process of coal combustion takes place, a heat exchanger where the coal is heated, and a grate. The heat exchanger can be made of cast iron or steel. Depending on this, cast-iron or steel boilers can be found on the market. What is the preferred material? Steel boilers are slightly cheaper. Why? A cast iron boiler will last longer. As for reliability, these structures are difficult to damage.

The advantages of coal furnaces include durability and high heat transfer. The heating system does not require electricity. It is clear that coal will have to be purchased in advance and a room for its storage provided.

Using electricity

The better to heat a country house when there is no gas and electricity, we have already told. If the building is connected to electricity, you can use electricity for heating. The building will not be heated by electricity, but by hot water. And electricity will heat the water.

How to equip such a heating system? First of all, you should buy a boiler in which water will be heated. Electric boilers can be designed for different capacities, have one or more circuits. If the system is with one circuit, then the water is heated only to heat the house. When there is a second circuit, water can be heated for a bathroom or kitchen. Sometimes two boilers are installed in parallel. In the summer, one of them can be turned off. The second will heat water for domestic needs.

Types of boilers

For residential buildings, wall and floor electric boilers can be purchased. The latter have more weight and size. Therefore, they are installed only on a horizontal surface.

Water (sometimes antifreeze) enters the boiler. Here, electrical energy is converted into heat. The liquid heats up and expands. The water pressure increases, the liquid independently moves through the pipes to the heating radiators. Batteries warm up and heat the building. The water is cooled and returned to the boiler for heating again. The system has a closed cycle.

In some cases, you can install a boiler with a forced circulation system. This will require an additional pump and expansion tank.

If a water heating system is not installed, but the electricity is connected to the building, other heating options can be provided. Now you can buy various types of heaters powered by electricity. Most often used oil coolers. They consume little electricity and are safe to use.

Infrared heaters are also used indoors. But they can only warm certain parts of the room. This type of heating will save electricity. Often this type of heating is used in summer cottages.

Infrared emitters a couple of years ago caused distrust. Now the situation is just the opposite. It turned out that this type of radiation does not pose a threat to health. Moreover, these rays help to cope with colds.

Precautionary measures

When heating buildings with a heater, you need to learn the basic precautions:

• do not dry wet clothes on the heater;
• make sure that the wire does not lie on flammable objects;
• try not to use too long extension cords;
• do not leave the heater on at night.

If you heat a building with wood (charcoal), you should also follow these rules:

• there should be no combustible substances near the red-hot stove;
• near the stove door, the floor should be made of an iron plate; if sparks fall on linoleum or wood, this will lead to a fire;
• As a result of combustion, hazardous substances are formed, a working ventilation is required so that the combustion products can escape the building.

The cost of supplying main gas and the related approvals pushes many owners of suburban real estate to organize a private house. Electricity is a great alternative to gas, safer and does not require special permits. The only drawback in this method of heating is the cost of paying bills for used kilowatts. In this publication, we will try to figure out whether it makes sense to heat a country house with electricity.

Possible ways of electric heating of a private house

There are two principles on which everything (CO) is built:

1. Direct. Heating of each room is carried out by devices powered directly from the mains.
2. Indirect. This principle is laid down, which heats radiators installed in heated rooms.

There are many opinions about which electric heating in a private house is better. The main argument of the adherents of the indirect method of heating a dwelling is the rather long process of cooling the coolant in the system, which gives advantages when the boiler is stopped. All those who use direct heating claim to benefit significantly from the purchase and installation of equipment.

How to heat a house with electricity

Consider the most popular options

• Water heating with electric boiler.
• Heating with electric convectors.

The first option involves the creation of a heating circuit, which uses pipes for transporting the coolant, radiators for transferring thermal energy to the room, as well as the devices and mechanisms necessary for the operation of the system (expansion tank, circulation pump, shut-off and control valves, safety and control devices).

In addition, the CO of your home is needed, according to the architecture of the building, design features and other factors.

The second option involves the installation of the required number of electric convectors in each room. The benefits are obvious: no need to create heating circuits, design and complex installation of equipment. All work can be done independently, without overpaying expensive specialists.

Consider the design features and principle of operation of each heating option, which will make it possible to conclude whether electricity can be used to heat private and country houses.

Electric boilers: design features, advantages and disadvantages

There are three principles of heating the coolant, which are used in modern hot water heating boilers:

• heating elements.
• Electrodes.
• Based on magnetic induction.

The first type of boilers is the most common. The coolant from the system enters the internal tank of the boiler unit, where it is heated by tubular heating elements, after which it enters the CO.

This type of equipment is safe, functional, has built-in automation to control the temperature of the coolant and air in the room.

In electrode boilers, a completely different principle is used to heat the coolant. The heating element in them consists of a pair of electrodes to which a high voltage is applied.

Electric current, passing from one electrode to another, heats the coolant, after which it enters the CO.

Important! In boiler plants of this type, the electrolysis process does not occur (which eliminates the appearance of scale) since an alternating voltage with a frequency of at least 50 Hz is used. Depending on the intensity of use, the electrodes become thinner over time and their ability to heat up is lost. Replacing the electrodes is a standard procedure in electrode boilers.

Structurally, induction ones look more attractive, although much more complicated. In this type of installation there are no (familiar to everyone) heating elements.

The coolant passes through the heat exchanger, which is part of the magnetic circuit, in which a powerful magnetic field is generated. It is it that heats the heat exchanger and the coolant, which circulates through the CO.

Electric heating of a country house, through indirect heat transfer, has its advantages over gas and air heating in the following: electric hot water boilers are quite reliable, have high efficiency and do not require a chimney.

As disadvantages of such heating at home, it can be noted that the use of electric boilers requires good wiring, stable voltage in the network.

Creating a water CO with an electric boiler requires significant initial costs, especially if you involve a third-party organization for project development, installation, configuration and balancing of the system. You should be prepared for additional costs for, which includes regular flushing of radiators, checking the operation of valves, etc.

Electric convectors: design and principle of operation

The design of the convectors is simple and therefore effective: dry heating elements are placed in the lower part of the metal (steel, aluminum) body, the operation of which is controlled by an adjustable thermostat. The air is heated, rises and exits through the grate at the top of the case. The “vacated” place in the device case is occupied by colder air masses, which, when heated, exit through the grille into the room. There is air circulation, which ensures uniform heating of the heated room.

Today, the Russian market of climate technology is represented by the widest range of convectors, which differ in power (from 1 to 5 kW), design and installation method (floor, wall, universal).

Requires minimal initial investment to purchase equipment and have wiring checked by a qualified electrician. The difficulty lies in the selection of the required power and the number of convectors. This will require calculations that are carried out by specialized organizations based on data on the heat loss of each room. However, one can also be guided by approximate data: 1 kW of power is required to heat 10 m 2 of a private house. For a room of 10 m 2, you need one small convector for 1 - 2 kW, which can be purchased in specialized stores for less than 100 USD. For example, in one of the largest federal online stores RUSCLIMATE a huge selection of convectors from 2241 rubles, and when ordering through the site, there is also a 3% discount. And in the climate company mircli.ru prices for convectors start from 2260 rubles .

Heating with electricity: benefits, costs, conclusions

In order to answer the question of whether it is possible to heat a private house with electricity, some calculations should be made.

Initial data: a brick house with basic insulation of the attic and floor, with an area of ​​150 m 2. Moscow region. We proceed from the data that heating 10 m 2 requires 1 kW of thermal power. To heat such a property, 15 kW of electricity per hour is required. In practice, during the heating season there are about half of such days when such power is not required. We accept the average value - 7.5 kW / h for heating the original country house.

So: 7.5 kWh multiplied by 24 hours and 30 days. We get 5400 kW. Since the average duration of the heating season in the central region of the country is 5 months, we multiply the obtained value by 5 and by the cost of 1 kWh in Moscow (5.03); 5400 x 5 x 5.03 \u003d 135810 rubles. This figure shows the cost of paying for electricity for the use of electric CO for one season. It is worth adding the cost of equipment here: for convector heating it will be 300-400 USD. For the water system, this amount will increase to 8 - 10 thousand USD for the creation of a JI project, the purchase of equipment and the cost of installation and commissioning.

For example, CO gas will entail the following costs:

• The purchase of the necessary equipment, design, installation and commissioning will amount to 10-13 thousand USD.
• With an efficiency of the boiler plant of 90%, the average gas consumption for the original country house will be 3.5 - 4 thousand m 3 in the season. In Moscow, the cost of 1 m 3 of gas varies within 6 rubles. In total, 24 thousand rubles will be spent per season.
• The cost of connecting to the gas pipeline is more than half a million rubles.

Even without going into details, the difference in operating costs is visible, on the basis of which we can conclude: gas heating is cheaper, except for the grandiose initial investments.

Tip: if there is no possibility, funds or desire to use gas as an energy carrier, then the most economical way to heat a house with electricity is to use electric convectors.
