A dwelling in the winter is associated with a cozy warm house, where it is pleasant for every member of the family to be.
Solution of the problem
If you are faced with the question of how to heat a country house without gas, then you should consider the most common methods of heating. Today it is electricity.
The inability to connect to the central gas supply line makes the owners of country and private houses think about how to economically heat a house without gas. There are a great many options for units and systems for heating today, but most of them are able to convert the energy of fuel combustion into heat by distributing heated air indoors through gas.
If you are thinking about how to heat a house of 200 sq. without gas, then you need to consider other ways to solve this issue. Many owners of private houses have recently been trying to switch to autonomous systems that are of higher quality, more profitable and more efficient. If you are a resident of a low-rise private house or have a summer cottage, then you can heat these buildings using steam heating, stove heating using different types of fuel, stone, and autonomous electric.
How to heat a house without gas and electricity, you can find out below.
Heating without communications
You can install heating without communications and pipes, while the system will consist only of heating devices. When choosing a scheme with radiators and difficult highways, living will become comfortable not only in one room, but throughout the house.
Use a variety of types of fuel - electronic, liquid, solid. It is worth remembering that its traditional types can not in all cases be called the cheapest and most convenient.
Basic home heating methods
If you are thinking about how best to heat a house without gas, then we recommend resorting to electricity, which acts as the easiest way to organize heating.
If we talk about profitability, then electricity is at the very last place in the rating. As a fuel for such devices, you can use diesel, which is also quite expensive. Thus, 1 Gcal of heat will cost 3,500 rubles. In this case, you will have to deal with an unpleasant odor that will form near the heating unit. Despite the shortcomings, diesel fuel is becoming an alternative affordable type of fuel for many consumers.
You can also heat your home with coal, which is a cheap form of fuel. With it, heating will cost four times cheaper compared to the above method. Thus, one thousand rubles will have to be paid for 1 Gcal of heat.
If you are faced with the question of how to heat without gas, then you can use peat, which comes in the form of briquettes. It will cost about one and a half times more than coal.
The most common option for heating a house is to use firewood, which costs little, but it is not always convenient to use them, but they will burn out much faster than coal.
For appliances that are installed in the house, you can use pellets, they are granules created on the basis of wood waste. You can get 1 Gcal of heat by paying 1500 rubles. At the same time, this type of fuel is very convenient to use for boilers in which fuel can be supplied automatically.
Heating without gas. Alternatives
With a permanent or temporary absence of the types of fuel to which a person is accustomed, it is possible to arrange heating at home without gas and even without electricity. According to practice, if these technologies are replaced, it will be possible to save significantly.
Considering different ways of solving the issue, you may prefer fireplaces and stoves that run on coal or wood. When choosing this option, it will be necessary to build the appropriate brick structures or purchase a ready-made unit. This will help organize an environmentally friendly way of heating, and some models of stoves allow you to cook food thanks to the presence of an oven and a hob.
If you are faced with an urgent question, how can you heat a house without gas, then we recommend that you follow the experience of some owners of private dwellings who resort to original technologies. They are heated by their own source of electricity. In this case, you can use one of two ways to generate electricity autonomously.
Heating from an autonomous source of electricity
How to heat a house without gas and electricity, you will learn by carefully reading the article. If you want to save money, while still being original, you can heat yourself with solar energy. To do this, you need to buy solar collectors that are able to convert the energy of the sun into heat. At the same time, you can use an autonomous heater that works without electricity. Initially, you will have to spend money on the purchase of appropriate equipment, but during operation you will receive light, as well as heat, almost for free.
Are you still thinking about how to heat a country house without gas? You can also use the technology that involves wind into heat. To do this, experts recommend purchasing a ready-made device that is capable of converting mechanical energy into electricity. Many home craftsmen assemble such devices on their own. It is worth noting that such a unit is quite simple in execution, you will need to make a windmill by connecting it to a battery and a generator. Such methods of obtaining heat, according to modern summer residents, are extremely beneficial for country houses in areas where there are no gas pipelines. This is especially true for rarely visited properties.
Heating without a boiler and pipes
The heating system can be equipped with a boiler, to which, as a rule, a structure of radiators and pipes is connected. At the same time, communications heat several rooms at once, which depends on the power of the device. For a country house, this is the most relevant solution, because there will be no boilers and pipes.
In summer, you can use one heat source, for example, a brick or metal stove is suitable, which will heat two adjacent rooms. Quite often, fireplaces are used with this technique.
If we are talking about an old Russian house, which is built on the principle of a five-wall, then one heat source, for example, a stove, will be enough for it. It is best placed in the center, between two adjacent rooms.
Heating based on a heat pump
If you are trying to solve the question of how to cheaply heat a house without gas, then you can use a rather interesting technique that does not involve the use of fuel. The technology is implemented using the operation of a unique unit called a heat pump.
Device and operation
The heat pump consists of tubes that are filled with freon, as well as several chambers, namely a heat exchanger, a throttle chamber and a compressor. This device will work by analogy with a refrigerator. The principle of operation in this case is based on liquid freon, which passes through tubes lowered into the ground or a reservoir. There, in winter, the temperature does not fall below plus 8 degrees. Freon under such conditions begins to boil, for this it needs only 3 degrees of heat.
Rising up, the substance, which becomes gaseous, enters the compressor chamber, where it is significantly compressed. As you know, if you compress any substance in a limited space, this leads to an increase in its temperature, so freon heats up to 80 degrees.
Giving the generated heat through the heat exchanger of the heating system, the mass passes into the throttle chamber, where the temperature and pressure decrease, thereby freon turns into a liquid. At the next stage, he goes into the depths to warm up and repeat the cycle again.
Still not sure how cheap it is to heat a house without gas? You can apply this rather effective technology, for the implementation of which, of course, you will need electricity. However, it will be consumed in a disproportionately smaller amount compared to direct heating of the coolant.
Varieties of heat pumps
If you are thinking about the question of how to cheaply heat a house without gas, then it would not be superfluous to consider the types of heat pumps that will be needed to equip the heating system using the technology described above. Models of this equipment differ in the method of heating freon, that is, in the source of low-level heat.
If the house has a surface reservoir, then it is best to choose a water pump that is designed specifically for this. This type of device is also suitable for groundwater. On sale you can find air and earth pumps. The name of the unit includes the type of coolant in the installed heating system. Thus, the passport for the device must contain the following words: "ground-air", "ground-water" or "water-water".
Heating a house without gas using electricity
Quite often, owners of country houses are faced with the serious question of how to cheaply heat a house without gas. The most common heating method is the one in which electricity is used.
Depending on financial possibilities, you can choose installations and equipment that will be able to provide maximum heating.
Electrical units are available in the following varieties: fireplaces, fan heaters, underfloor heating systems, infrared heating, and convectors. Popular "warm floor" systems are often used for heating residential premises, if there is a need to heat the house without using gas. They are installed not only on the floor, but also on the surface of the walls, as well as the ceiling. For a country house, the most relevant solution will be fan heaters, which in a short time increase the temperature inside the premises to an acceptable level.
Use of electric boilers
When deciding how to heat a house without gas inexpensively, be sure to consider electric boilers as an option. This heating system will be more complex in execution, but at the same time the most effective. You will need to purchase and install a boiler that will heat the water to the required temperature. After that, the coolant will circulate through the heating system.
Considering it as a heat source, there are many advantages, among which are the following: the ability to heat a home in a short time, ease of use of equipment, the ability to adjust the level of heating, as well as installing a heating system at any time, which allows heating without gas.
The use of solid fuel boilers
When deciding how to heat a private house without gas, you may prefer a solid fuel boiler. Especially this heating option has become popular in European countries. This type of solid fuel units is able to provide economical heating, as well as ease of use. Such devices work not only on wood, but also on pellets, coal, and also peat. Heat will be supplied through the pipeline thanks to the water, which acts as a heat carrier. This method of heating for a long time allows you to maintain the required temperature inside the premises, all this is ensured due to the rather long burning of fuel in just one load.
Conclusion
After you have learned how to heat a house without gas inexpensively, you can implement one of the ideas presented above. It is important to determine exactly which of them will be optimal in a particular case.
Simple, reliable economical heating for a small country house will please everyone. What heating for a country house will be optimal?
A small country house is a great place to spend weekends.
But it needs to be heated, right? - to spend the weekend there not only in summer, but also in winter. In a house where they do not live permanently, but are mostly from Friday evening to Sunday afternoon, heating can be simpler.
The priority is economy with sufficient comfort. As well as the ability to heat the house without the presence of residents.
Spend a winter evening near the heated stove, admire the play of the flame….
This is a great vacation that cannot be discounted when considering options for how to heat a country house.
A simple heating scheme
The simplest, most reliable and cheapest way to heat a small country house is a combination of a heat-intensive massive stove installed in the center of the building and electric convectors installed under the windows, in the usual place of radiators.
Such heating for a small country house (up to 80 square meters, with a special layout, when a stove located in the center can heat all rooms) combines seemingly incompatible things - automation and programming, extreme simplicity, almost absolute reliability. And at the same time, comfort and sufficient ease in providing heat without the presence of main gas are provided.
What is the best heating mode for a country house
It remains on all objects and walls in the form of water during cooling, during the transition through the dew point. The house should not be frozen, it is always necessary to maintain at least a minimum positive temperature of +5 - +7 degrees C in it.
For this, several (3 - 5 pieces according to the number of large windows) electric convectors are enough. By setting them to turn on +5 degrees and turn off +7 degrees, you don’t have to worry that the house will freeze. After all, power failures do not happen for more than a day in this area?
It is extremely inconvenient to drain water from the boiler and the entire water supply system when leaving a country house on Sunday. Then on Friday the whole system needs to be put in order again. It is better to constantly maintain a minimum positive temperature in a country house (dacha). And besides, warming up a house from +5 to +20 degrees is much faster than from minus twenty degrees.
How much does it cost to keep warm
Is it expensive to maintain +5 degrees C in the house with the help of automated electric convectors?
In this case, no more than 20% of the energy of that amount will be consumed if we maintained +20 degrees. When the temperature drops by one degree, 6% of the energy carrier is saved. A difference of 15 degrees gives us as much as 90%. We believe that we will save 80%. Thus, maintaining the temperature from Tuesday to Friday morning with electricity is not at all expensive.
And why from Tuesday, where did Monday go? The significant heat capacity of the stove will not allow the temperature inside the house to fall so quickly, provided that it is sufficiently insulated.
Conventional insulation will provide not only comfort, but will reduce heating costs by 2-3 times. It is possible to insulate a house even cheaper, without the use of widely advertised expensive heaters, - you can read,.
Furnace heating is not comfortable?
Some decrease in comfort during stove heating, when places near the walls remain cold, can be bypassed firstly, .... an explanation that the house is not for permanent residence, and this can be perceived more as an exotic, an excursion into the old days. And secondly, if the cold near the window really gets it, then it is very easy to neutralize it with a convector turned on at minimum power, i.e. without the risk of going bankrupt.
So, we heat a country house with a stove that is simple, reliable, and does not heat up for long.
It is important to make the stove heat-consuming, one that would keep heat in the house for a long time. There are many designs of ovens. Usually two options compete in terms of convenience and efficiency - the Russian stove and the Finnish stove. But you can invent your own.
The cost of the furnace will be comparable to the cost of a heating system with a conventional solid fuel boiler.
Only the boiler and the entire system on the coolant are complex things, there are many mechanisms, there is something to break - the pumps stop, the radiators leak, the pipes pass, the boiler smokes.
And the stove does not break down at all, it requires care only for the annual cleaning of the chimney.
At the same time, a special atmosphere of relaxation and celebration does not come from a fouled boiler installed in a closet. In this, he loses the stove by 100%.
And in order for the heating system with a boiler to acquire a heat capacity such as that of a furnace, it is also necessary to build in a buffer tank for a large amount of coolant (anti-freeze), and then boiler heating becomes more expensive.
It is possible to find a good furnace specialist, but you need to agree to make it conscientiously - a large heat-intensive furnace, with a long chimney, with an extremely high efficiency, giving out the already cooled gases.
In general, in terms of price / quality / reliability / convenience for a small house, the stove wins in all categories. It loses in terms of comfort, since it can be cooler near walls and windows, which was mentioned earlier about leveling.
A popular option for a small country house - cottages for weekends can be heated not expensively, but efficiently. How to do this was suggested above.
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.
- centralized;
- autonomous;
- individual.

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:
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, 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. 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.
It is realistic to provide a cheap and efficient heating system. The electric convector is built on the principle of natural air circulation. From the heater, warm air moves upwards, thus stimulating the movement of air inside the room, and ensuring uniform heating. However, the convector is effective only in a warm climate, when the temperature does not fall below 10-15 degrees.
pros
- No forced air blowing. Even in the cleanest home, there are solid particles that lie on surfaces. By artificially blowing warm air out of a heater, this dust becomes part of the air we breathe. Natural air circulation is not so active, therefore, dust does not rise into the air.
- Small size with sufficient power. The heating elements of convectors heat up quickly, converting electricity into heat with an efficiency of up to 80%. In addition, there is a system of operation in different modes, as well as thermostats that allow you to work not constantly, but only when the air temperature drops.
- Mobility that allows you to move the convector around the room, to places with maximum cold supply.
- The possibility of creating a heating system exclusively with the help of convectors or using them as an integral part of a more complex heating system.
- The electric heating element does not heat up more than 100 degrees, and the body - 60 degrees. They have an increased level of protection against moisture, which allows the use of the convector in the kitchen and bathrooms.
Minuses
- The disadvantages of electric convectors is the installation of heaters in every room of the house.
- In addition, if you turn them on at the same time, then there is a possibility of exceeding the limits of permissible power.
However, the minuses can be turned into pluses by installing a relay for turning on the heaters in turn. The relay will allow you to create a stable temperature in the house, reduce energy costs and stay within the allowable power. There is one more argument in favor of a system of convectors - they will not fail all at once. Replacing one or two appliances without losing heat is not difficult.

Method 2 - tubular electric heaters
Heat is transferred from a tubular electric heater to a liquid-based heat carrier. Usually, water and oil are used as a coolant, sometimes antifreeze. The principle of the device of heaters is the same as that of electric kettles, therefore they are also called heaters and oil radiators. In fact, this is a boiler placed in a vessel with water. The efficiency of such devices is quite high, and heat loss for heating is minimal.
pros
- The undoubted advantages of tubular heaters include their safety, reliability of operation and versatility of use.
- They can be used in both gaseous and liquid media.
- Not explosive, and not afraid of vibrations and shocks.
- Tubular heaters are available in a variety of design solutions, which allows you to economically heat a private house with electricity without violating the aesthetics of the interior.
Minuses
Heating elements have a high cost due to the expensive metals that are used in production. Since scale forms on the tubes, it is necessary.
A tubular radiator is a thin-walled metal tube with a spiral inside, so if you do not need particularly high temperatures, then you need to take a heater with carbon steel tubes. If the device must produce a consistently high temperature or work in an aggressive environment, then you need to take a device made of stainless steel.
Pictured is a do-it-yourself tubular electric heater
Method 3 - warm floor
As the only source of heating, they are chosen to free up usable area, i.e. arrange heating without the use of radiators. In addition, the uniform distribution of heat in the room helps to reduce dust in the air. I recommend buying electric floors in the form of heating mats - this will greatly simplify installation.
Method 4 - electric boiler with heating element
Popularity is determined by their safety, low cost and reliability. Most consumers stop at heating element boilers - they are much cheaper than electrode and induction boilers, and they are easy to maintain.
However, due to the use of a thermoelectric heater (TEN), such heating cannot be called the most economical. In addition, before buying, I recommend clarifying the operating mode of local power networks - perhaps the networks will not be able to cope with the load you need and the purchase will be in vain.
Pictured is an electric boiler KOSPEL, Poland
Method 5 - induction boiler
This is a transformer with two types of winding. The resulting eddy currents follow a short-circuited coil, which is the boiler body. In this case, the secondary winding receives energy, which is converted into heat, which heats the coolant.
Induction boilers quickly heat up the house, can operate at low voltage and do not contain parts that fail. The efficiency of such a boiler is almost 100% and does not depend on the period of operation.
The photo shows an induction boiler EPO Evan for 9.5 kW, Russia
Method 6 - electrode boiler
Inside there are electrodes, which act as a heating element. When current passes through a liquid, heat is released. This means that in electrode boilers there is no actual heating element on which scale could form. The absence of scale will greatly facilitate operation.
Electrode boilers are highly reliable and operate much longer than tubular heaters. In addition, they are small in size, which is very convenient for a small residential building. The disadvantages include high requirements for the liquid used as a coolant. Water must be subjected to special treatment. Often, antifreeze should generally be exclusive - from the device developer.
In the photo, the Galan electrode boiler, Russia
Method 7 - infrared heaters (most economical)
Infrared heaters are considered the most economical of all types of electric heaters. They do not need heating elements and pipes with water. Infrared heaters heat objects, not the room. Then the air is heated from the heated objects. If an electric boiler can be compared with a kettle, then an infrared one can be compared with a microwave.
Infrared panels are especially popular. They are installed on the ceiling or on the walls of residential and industrial premises. Since the heating area is increased, the room becomes warm faster than usual. You can use such a panel as an independent source of heating or as an addition to an existing system. The infrared heater is well combined with electrode boilers. For example, an infrared heater can only be turned on in spring and autumn, when it is too early to turn on the main heating, or when it suddenly gets cold outside.
Pictured is a GROHE infrared panel, Germany
conclusions
- It is generally accepted that heating a house with electricity is not a cheap pleasure. This, of course, is true, if we mean only payment by tariffs. However, the cost of equipment, as well as the cost of its maintenance and repair, must be added to the price of heating.
- If we compare bills for electricity, firewood, coal, pipes, boilers and other equipment, we can conclude that private electricity heating is cheaper than stoves and other systems alternative to gas heating.
- In addition to money, there is another argument in favor of electric heating - it is time saving: turn it on, leave it and forget it. The only downside is a sudden power outage.
Watch the video below on how you managed to make cheap heating with electricity of a large private house.
Heating your home with electricity is one of the most convenient and efficient ways to heat your home. It has a lot of advantages over traditional heating technologies that use gas, coal or wood as fuel. Previously, the electric heating system had a significant drawback in cost, but modern technologies make it possible to level it. We will talk about how to make home heating with electricity inexpensive and we will talk in this article.

Why electricity?
Electric heating differs from classic water-furnace and gas systems in greater efficiency and practicality. We will leave the first aspect for discussion a little lower, and describe the operational advantages here:
- Electric heating is not only silent, but also environmentally friendly. It is transported safer than gas and does not emit harmful substances at all, both into the atmosphere and into the room. In the absence of waste, the need for exhaust chimneys and traction structures also disappears. Heating on coal or wood is not at all comparable to electrical systems.
- Heating with electricity does not require large one-time costs. You can make a comparison using the example of gas: in order to connect a house, you must purchase equipment for each room, install communications, a boiler, and crash into a common highway. Moreover, it is necessary to do all this together, since it is impossible to postpone bringing some part of the house to the system. And the electric method allows you to organize sequential installation: first, the most important parts of the house are connected, and then, as funds accumulate, peripheral ones.
- Due to the possibility of using a multi-tariff meter in a private house or apartment, as well as the constant development of technologies in this area, heating with electricity is already the most economical among analogues. Do not focus on the high price of equipment - it quickly pays off due to low energy consumption.
- Almost every method of organizing electric heating allows you to do the installation yourself, without many additional tools.
Of course, the use of electrical systems for heating cannot be called ideal. Work on high-quality heating of each house requires taking into account many features. In some regions, the cost of electricity can be so high that gas cannot be abandoned. In old apartment buildings, it is difficult to switch to electric heating for two reasons: it is very difficult to disconnect from the central highway, and the power grid will have to be built again, taking into account powerful equipment.
Despite this, the overall picture tips the scales in favor of electricity. For rooms in which there is no gas or there is no possibility of supplying it, it is a real salvation.
Varieties of heating systems
There are several ways to organize electric heating in your home. Each of them has its own advantages and disadvantages. Some are cheaper at the stage of purchase, and some save significantly during operation. Let's look at what features each method has:
- Installation of an electric boiler designed to heat water flowing through the pipes of the heating system. Perhaps the most well-known method, but it is far from the most effective today. Manufacturers claim that current models have become much more productive and now consume 80% less energy, but this is a moot point. Manual switching on and off of the boiler is, of course, impractical, and automatic at a given interval does not take into account the temperature regime of day and night. A more or less economical option is to install thermostats and appropriate automation to turn on depending on the temperature in the rooms, but this is difficult in terms of installation and very costly. Reduced power models with equal performance are also nothing more than advertisements. Such a boiler, most likely, will not have enough “strength” to heat a large private house.
- infrared panels. This is not just a way to heat rooms, but a fundamentally different technology. The point is not to warm up the air (which has a very low efficiency), but to influence the objects located in the room. Under the light of IR lamps, floors and furniture heat up and begin to emit heat themselves. The fundamental difference is that the traditional "radiator" method of space heating actually heats the ceiling (warm air from the battery rises), and the floors remain cold. With infrared heating, the opposite is true. The light is directed downwards, which means that the warmest place is the floor. Complement the system with thermostats - and economical heating of a country house, private house or garage is ready. And the opinion about the dangers of infrared radiation on a person is nothing more than a myth. The main thing is not to be under the lamp for a long time, and nothing dangerous will happen.
- The use of convectors. According to manufacturers, this is the most efficient way of space heating, which combines high performance and economical energy consumption. Both of these statements are the subject of a long dispute, since the technology is based on the same "radiator" principle, and many individual characteristics should be taken into account in heating a house. The main difference lies in the significant ease of installation and operation and lower price. An important advantage of convectors is fire safety, which is very important when heating a country or private house made of wood. Convectors allow you to install them sequentially from room to room, they are compact and pleasant to look at, and they are also protected from power surges.
Inappropriate Options
There are several types of electrical equipment designed for space heating, but not recommended for use as the main source of heat:
- Thermal fans. These devices have the simplest device and are a large hair dryer, consisting of an incandescent spiral and a fan that drives a stream of air through it. Their use will definitely not be cheap - the air cools extremely quickly, and it will not work to maintain a comfortable temperature for a long time. Do not forget also about the loads on the electrical network and the harm - too dry air is harmful to domestic plants and people.
- Oil radiators are probably the most common device used by residents of apartment buildings when there is not enough central heating power. Surprisingly, this is still the least efficient way of heating. And even if it is possible to heat the room to a comfortable temperature, it will come out not at all cheap.
Why is this equipment so common if it is inefficient. The fact is that all these are auxiliary devices designed to help out in emergency situations or when the main heating does not cope with its tasks. For a garage, for example, constant heating is not always needed. For the period of repair work, it can be heated with a heat gun (fan heater) powered by electricity or gas. But in a house where it is necessary to constantly keep the temperature at a certain level, infrared panels are much more effective.
Organization of economical heating
You should not have a long debate about which equipment of the listed options best combines economy, efficiency and safety. It will be much more practical to use one or another option in the most suitable conditions. Below are the basic principles that should be followed in order to create economical heating with electricity at home:
- The first rule is common for both gas and electric systems - keep heat loss to a minimum by insulating walls, ceiling and floor. Thanks to this, you can reduce the required heat output to maintain the temperature. Of course, additional costs are necessary for this, but they pay off with savings in electricity. The temperature inside an insulated garage rises above zero in winter in half an hour if a car is running inside. In an insulated house, you will only need to maintain heat, and not constantly pump it, forcing the equipment to work at increased power.
- Design an optimal electric heating system. For example, an electric boiler can be quite effective for heating a small one-room apartment (if the heat loss is very small). But for a house with a large number of rooms, this is not the best option. Here it is more convenient to install a convector system with thermostats that control the climate in each room. Infrared panels are good for a garage, closet, or utility room that doesn't need to maintain a constant temperature.
- In rooms and houses that are not used throughout the day, it is optimal to combine electric heating equipment. As an example, let's take a kitchen with a main convector and an auxiliary IR panel. The convector allows you to maintain a minimum temperature throughout the day, and the panel turned on before the evening meal will quickly warm the room for a comfortable dinner. Similarly, you can arrange the heating of a bathroom, outbuildings or a heated garage.
- Thermoregulatory automation allows you to accurately adjust the temperature. Depending on specific models and devices, you can set "hot" and "cold" periods, use photo sensors to make the room warmer in the presence of people, and apply other settings. All these seemingly insignificant little things can greatly help in reducing costs.
- A large proportion of the consumption of the heating system falls at night, when all residents are at home. You can significantly reduce bills for this period by switching to two-tariff electricity metering. The night rate, as a rule, is 3-4 times lower than the main one. To replace the meter and change to the new metering rules, contact your local power supply company.
Electric water heater
As we can see, economical heating of a private house without gas is quite feasible. The main thing is to carefully plan the transition to electricity, consider which devices to use for the main premises, and which ones for the periphery (garage, bathhouse, and other buildings). Of course, buying everything you need can cost a pretty penny, but these expenses are offset by the amount that you will save over the coming years.
