The most expensive resource today is energy. But you can’t do without them even in summer, and in winter, heating your home is a significant expense item. How to determine the most economical way at home?
There is an inverse relationship between the efficiency of heating and the cost of equipment: the more expensive the purchase, the cheaper the operation will be.
What is the most economical heating in a private house - there is no universal answer to this question.
In forests, the cheapest fuel can be firewood, in areas of coal or peat mining - respectively, coal or peat.
Somewhere there is an opportunity to connect gas, but somewhere it is not. The most economical electric heating is expensive anyway, but there are options to choose from.
For heating houses are used:
- and convectors;
- solid fuel - firewood, pellets, coal, peat, briquettes, woodworking and crop waste;
- liquid fuel;
- , other electrical appliances;
- heat pumps. We will not consider this option: the installation of the system is very expensive, it pays off from 10 years;
- solar panels and collectors. Installation is not justified: batteries collect little energy on winter and cloudy days.
The purchase of a diesel boiler is justified when the economy is large (for example, a farm), and the owners have access to cheap fuel. Diesel boilers are produced only with high power; for a medium-sized house, these are not required.
And the equipment has many disadvantages: environmental damage, noisy operation, large dimensions and weight, fire hazard. Environmentally harmful and fire hazardous is also a compact modification of the liquid-fuel unit - a mining boiler. It is low-power, but they don’t put it in the house, only in utility buildings.
Another option is how to save on heating a private house: purchase a combined / universal boiler for two or more types of fuel. When buying it will cost more than any other.
But, firstly, under no circumstances will you be left without heating: in the absence of one energy carrier, you will switch to another. Secondly, there is room for savings. For example, expensive electricity can be burned only at “cheap” night time (with two-tariff payment), and during the day it can be heated with wood or coal.
System features
Not all methods of heating a private house include a water pipeline, although it is the most popular. Another option is air heating. This includes gas and electric convectors, all other electrical appliances, except for an electric boiler - it works with liquid heat carriers.
In the solid fuel category, this is a Buleryan boiler - it heats the room according to the principle of convection through pipes extending from the furnace. With a large area of \u200b\u200bthe house, air ducts are connected to the nozzles.
Scheme of the device of the boiler "Buleryan".
If we talk about water systems, the first question is competent design. In a small one-story house, you can install a system with natural circulation, without a pump, and do without electricity at all. For a large area, this option is not suitable, heating will be uneven and inefficient.
In a large house, beam wiring outperforms others in terms of efficiency: all heaters receive a hot coolant. No need to set the initial high temperature, and this is fuel saving.
If you prefer underfloor heating as heating devices, your choice is a condensing boiler (). They are low temperature, but the efficiency is the highest in the category.
Relatively recently, a new way of heating houses has appeared in Russia - biogas. Also gas, but obtained by "home" methods, you do not have to pay for it. How to make cheap heating in the house: install an airtight container, put organic waste in it regularly and add water. The gas that is released during fermentation is redirected to the domestic gas pipeline.
solid fuel
Wood burning is the most economical heating of a private house without gas (). In addition to firewood, there are units on other types of fuel. The choice depends on what is cheaper for you. If there is more than one cheap fuel, buy a boiler with two fireboxes.
You can save on operation if you purchase a long-burning boiler ().
There are three types:
- with an extended chamber and metered oxygen supply;
- with top ignition;
- pyrolysis, burning, in addition to the fuel itself, the pyrolysis gas released during combustion.
It is necessary to put firewood into the furnace of an ordinary boiler at least every two hours. For the most "long-playing" pyrolysis fuels are added twice a day (). This is not only more convenient, but also much more economical.
Electricity
Let's try to choose cheap heating of a private house in this category. When installing a water system, a boiler is used. It is more expensive to operate than others, but with proper organized heating, costs can be reduced.
Other options:
- oil coolers;
- heat guns and fan heaters;
- convectors;
- infrared equipment.
Guns consume a lot, they are not designed for permanent work. This is an emergency option when you need to warm the house in a matter of minutes. Oil heaters consume less. Convectors are even more profitable, especially with good placement: floor and baseboard convectors are considered the most effective. The devices are low-power, for full heating you will have to install several pieces.
Warm floors are cable and infrared. Experts call infrared floors more economical and efficient. High efficiency is achieved due to the fact that not only the principle of convection works, but also the reflection of heat waves from any objects in the room, ceilings, walls.
For a very cold winter, one floor may not be enough. In such cases, the infrared film is also installed on the walls and ceiling.
Video about how cheaper it is to heat a country house.
Almost every owner of a cottage seeks to reduce the cost of heating it to a minimum. But choosing the most economical heating of a private house, many often look only at the price of fuel.
However, here it is necessary to take into account both the heat loss of the building, and the capital investments for the arrangement of the heating system, and the cost of maintaining the network subsequently. Do not forget about the complexity of the operation of one or another option. Only an integrated approach to the issue will help make the operation of the heat supply network as economical as possible, agree?
In the article, we have collected the most effective ways to improve the efficiency of the heating system, provided practical advice on reducing heat loss, and also assessed the feasibility of using renewable energy sources.
Before choosing fuel, a boiler (or other thermal energy generator) and a heat distribution system for a cottage, you need to take a closer look at the house itself. If heat losses through walls, windows, ventilation, underground and roof are huge, then no tricks to increase the efficiency of the internal heating circuit will help.
First you need to take care of the insulation of all structures and engineering systems of the home.
With a high level of heat loss, any attempts to increase the efficiency of the heating system will be pointless, anyway, most of the heat will go outside. And it will require a lot. The enclosed space of a cottage is one thing, and a street open to winds and bad weather is quite another.
The technology and materials of insulation are selected based on the climatic conditions of the area where the house stands. There are certain building codes with minimum requirements for wall thickness and thermal insulation for each Russian region. But without knowledge in heat engineering, it is not worth doing a project on your own.
Either the calculations will be made incorrectly and the heat loss will be higher, or you will have to overpay for a too thick layer of insulation.
When viewing the finished project and the subsequent construction of the house, special attention should be paid to:
- double-glazed windows- up to 25% of all heat losses go through the windows to the street;
- roof and attic floor- this is another 10-15%;
- ventilation system– the proportion of heat loss through ventilation with natural circulation can reach 40–50%.
Walls and floors are also places for heat to escape from a building. But no one neglects their warming initially. But about ventilation, and the attic, many owners of private houses often forget.
Another point is the presence of "cold bridges" in the building envelope. Any iron part penetrating the wall from the street inside serves as a place of simply enormous heat loss.
Even a small metal pin, albeit slowly but inexorably, “draws” heat from the housing. The project should not have such bridges, and during construction it is important to ensure that they are not formed from various metal fasteners.
In the picture with a thermal imager, it can be seen that windows cause considerable heat loss, so you should not forget about the need to install energy-saving double-glazed windows
In addition, "cold bridges" can be:
- ends of floor slabs;
- window and door slopes;
- basement walls;
- lintels and inserts made of concrete or iron.
All these places must be carefully insulated, otherwise you can not even dream of saving on heating. No one has ever succeeded in heating the street.
Depending on the quality of insulation, the coefficient of thermal conductivity for one building that appears in the heat engineering calculation can differ significantly. The thicker the insulation and the fewer points of "leakage" of heat, the smaller the amount of fuel that has to be burned afterwards to heat the cottage.
The money spent on reducing heat loss will definitely pay off. You should not skimp on this issue, but you should not forget about the reasonableness of investments either.
Choice of the cheapest fuel
The second question in saving on heating is this. Moreover, it is necessary to look not so much at the cost of a kilocalorie at the outlet of the boiler, but at the total cost of fuel, heating equipment and its maintenance. It is necessary to consider everything in a complex.
The cheapest in terms of the price of generated thermal energy are wood pellets and main gas, but they are also the most expensive in terms of initial costs (+)
If we compare various water heating units, then they will be the cheapest. However, electricity bills are unlikely to please anyone later. Plus, for a large cottage, in most cases, you will have to lay an additional cable.
For a well-insulated house of 100 square meters, the existing capacities may be enough. But to heat a two-story dwelling, electric “fuel” will require much more. At the same time, standard networks were not originally designed for such loads.
Natural gas in Russia is considered one of the most economical ways to heat private houses. However, there are several nuances here. If there is already a highway in the village, then it happens quickly and inexpensively.
But if the distance from the house to it is 200 m or more, then inserting into this pipe will cost a pretty penny. Plus, all approvals and obtaining technical conditions can take up to a year.
For and equipment for it will have to pay from 150 to 250 thousand rubles. Fortunately, most of the companies involved in such equipment perform all the work in a couple of days.
Liquefied gas for him, in the end, at a price in almost all Russian regions is equal to what comes from the main pipe. But the initial costs frankly bite.
Another fairly cheap boiler is one that runs on mining or diesel. Moreover, if fuel can be obtained at a reasonable price, then this may well become the most economical way to heat private housing.
Averaged over Russia, the options for heating a country house in the aggregate of all costs are arranged in the following order:
- Stove on wood or coal.
- Gas boiler on main gas.
- Drovyanoy.
- Boiler equipment for liquid fuel.
- Electric boiler.
The most economical option is a conventional wood or coal stove, provided that there are no problems with fuel in the area of \u200b\u200bresidence. The cheapness of fuel and the cheapness of equipment also affect here.
However, such a furnace requires constant supervision. And that takes a lot of time and effort. Plus, it is unlikely that it will be possible to especially increase the efficiency of the heating system connected to it. It is difficult to adjust anything or somehow control the economical consumption of logs (coal).
Much in the matter of the cheapness of fuel depends on its availability in the area where the house is located - in some regions coal or firewood is the cheapest, while in others gas is ready to give them a considerable head start
The most convenient and safe to use electric boiler. He does not need a chimney, plus the automation itself monitors everything and, as necessary, heats the coolant in the system.
With proper installation of electrical wiring, the likelihood of a fire with this method of heating is reduced to almost zero. He certainly should not present other problems.
However, electricity costs are frankly high. It’s also good if you can connect a two-tariff meter with a reduced night rate. Otherwise, opting for an electric boiler is only a last resort. It is difficult to call it the most “economical” due to the high costs of “burned” kilowatts of electricity.
Improving the efficiency of the heating system
To increase the efficiency of home heating, it is also possible and necessary to introduce various technologies that reduce fuel consumption into the heating system. There are a huge number of ways of piping from the boiler to the radiators alone.
Some of them are cheaper to sell, while others are the most economical in terms of reducing losses during transportation of the coolant to the batteries.
The efficiency of the heating system at home depends on the correct power of the boiler, the piping layout and even the material of the pipeline.
There are heating equipment of different design and various additional equipment that can increase the efficiency of the entire system by 10–15% or more. But here you should carefully weigh the pros and cons. In some cases, the costs at the initial stage may not pay off later.
Do not chase the "most economical" and "most efficient" options. Often these are just advertising slogans and nothing more.
Method # 1: piping and "warm floor"
The most economical piping scheme is with a central manifold. With its use, each radiator receives the same volume of coolant.
Moreover, it is possible for each battery to adjust the amount of heat supplied individually. Excessive waste of thermal energy during the transportation of heated water through heating pipes with such a wiring is practically excluded.
The collector piping circuit of the boiler is the most effective in terms of balancing the hydraulic resistance of individual circuits and the controllability of heat flows (+)
Almost always, with collector wiring, the heating system has to be supplemented. Thanks to him, the difference in water temperatures at the inlet and outlet to the network is significantly reduced.
As a result, the controllability of heating the coolant and the efficiency of the entire system are increased. Fuel in the boiler has to be burned less, the result is direct savings on fuel.
The beam (collector) option is the most economical in operation. However, due to the large length of pipelines, it is also the most expensive to implement.
To maximize the efficiency of the heating system to the maximum, you can simply abandon the radiators by changing them to pipes of a "warm floor"
Heat from conventional batteries first rises to the ceiling, and only then spreads throughout the room due to convection. As a result, the hottest air is under the ceiling. And so that the legs in the cold outside the window do not freeze on the floor, you have to open the radiators to the fullest. And this is again an additional cost for heat generation.
The system is the most economical way of heating residential premises. In this case, the warmest air is concentrated at the bottom at the level of the person's legs. At the same time, heat consumption is reduced, and the most comfortable conditions for people are created in the room.
Method # 2: the most efficient boilers
The highest efficiency for pyrolysis and condensing boilers. It is difficult to find more economical heating equipment in heating engineering stores. The first option uses wood as fuel, and the second uses gas. In terms of efficiency, they overtake all other analogues on any combustible coolant.
The pyrolysis boiler differs from a conventional wood-burning boiler in the presence of a second furnace and in the fact that, in fact, it is not wood as such that burns there, but the gas obtained as a result of pyrolysis.
At first, logs smolder in it at a high temperature and a limited supply of air. And only then the gases already obtained as a result of this burn out in the main chamber with the release of heat.
Compared to a standard wood-burning counterpart, it has a higher efficiency (by 30-40%) and requires less attention to itself. The interval between loading firewood, depending on the capacity of the firebox, reaches 10–16 hours.
Savings here are formed due to absolutely complete combustion of fuel and a minimum of heat output with combustion products into the chimney.
The gas condensing boiler is even more economical - it takes thermal energy not only from the burned methane, but also from its combustion products
Taking into account the collection of additional heat, the final efficiency of such a boiler reaches 105–110%. Here, the energy of both the burned gas and the energy obtained as a result of the condensation of water vapor occurring in the second chamber is taken into account.
Method # 3: choosing a heat accumulator
Another fairly effective way to save on heating is to connect a heat accumulator to a solid fuel boiler. The latter first accumulates heat in itself, and then gradually releases it to the batteries.
At the same time, it is not necessary to forcibly limit the power of the coolant heating equipment, throwing heat simply into the chimney pipe.
If electricity is supplied to the cottage at different rates day and night, then the heat accumulator can also be included in the system with an electric boiler. In this case, it will accumulate heat at night, when electricity is cheaper.
Renewable heat sources
With a detailed cost calculation for heat pumps, windmills, solar collectors and batteries, the situation is as follows. They generate heat and electricity for a private house only at first glance for free. Of course, the sun and wind do not bill for heating, but such equipment for generation is very expensive.
It is in Europe that renewable energy is sometimes subsidized from the state budget. Plus, the price tag for fossil fuels frankly bites them. Therefore, there "green technologies" are economically justified and relatively effective.
In Russia, the situation is radically different. Our state is not going to subsidize yet. And the prices for domestic firewood, coal and gas, in comparison with neighbors in the west, are not so high.
As a result, heat pumps, solar panels and windmills are hardly economical in terms of the total cost. They mainly show their effectiveness only in remote areas, where it is difficult and expensive to deliver burned fuel.

Owners of private real estate can independently choose the type of heating system. Economical heating of a country house is quite possible if you follow some tips and choose the right heating equipment. How it looks, you can see in the photo. Heat sources can be wood, electricity, gas, liquid fuel. Each type of heating device has both disadvantages and advantages, so making a choice is not so easy. It is important to determine which heating in a private house is the most economical for each specific case.
In addition, at present there is an opportunity to resort to the use of alternative types of energy - the installation of such heating systems is very expensive, but the heat source is absolutely free.
Thus, if you are interested in economical heating systems, then electric heaters can not even be considered (in more detail: "").
Solid fuel boilers
Wood burning stoves have been used by mankind for hundreds of years. If you wish, you can install a fireplace in the house and enjoy the play of flames on winter evenings. However, the most economical heating of a house on wood is impossible - despite the fact that wood is cheaper than electricity, it is still very expensive to use this source of heat permanently.Peat briquettes, granulated wood chips and coal are also suitable as raw materials for solid fuel boilers. These types of fuel are much cheaper than firewood, and are often used to heat private houses, especially in areas where there is no access to the gas main.
Often, with the help of gas boilers, a traditional water heating system is created, the same as in apartment buildings. Such a unit is installed in a separate annex - it is categorically not recommended to place them in residential premises due to the release of gas combustion products (read also: "").
Oil boilers
This type of heating equipment is not so common compared to gas and solid fuel, but liquid fuel boilers also allow you to save a lot on heating. When using liquid fuel, an economical heating system for a private house is obtained, and the equipment itself is inexpensive (read also: "").- mini radiators. One of the novelties, so far little known, is a system that uses mini-radiators installed under the baseboard. Such equipment allows you to effectively warm up the premises without taking up precious space and without affecting the interior.
The principle of operation of mini-radiators is based on the fact that they do not heat the air, but transfer heat to surrounding objects. They, in turn, contribute to the heating of the air. As a result, the entire room is evenly heated, and at the same time, you can save up to 30% of electricity. Thus, it is not only convenient, but also economical heating for the home (more details: "").
Inside the system are heating elements that heat running water. The equipment uses a small amount of water - for a plinth 12 meters long, 4 liters of coolant is enough. Manufacturers give a guarantee on their products for 3-5 years.
- Infrared heaters. They allow you to save up to 60% of electricity, and they do not take up much space. For space heating with the help of such devices, the installation of boilers and pipe laying is not required. Therefore, if you are interested in how to save on heating, then you should pay attention to infrared heaters - they consume a small amount of electricity, but are easy to install and do not require expensive communications.
Infrared film allows you to improve the indoor climate without consuming a lot of electricity. However, it is not enough to effectively heat the house, it can only be used as an additional source of heat.
It makes sense to install solar systems powered by solar energy in the southern regions, where there is a large number of sunny days a year. With the help of the sun it is possible to heat water for the heating system and domestic needs. However, in winter, solar systems may not be enough to properly heat the entire house, so it is recommended to supplement them with traditional boilers. See also: "".
Geothermal systems allow you to use the heat of the ground to heat a private house. In each region, the freezing point of the soil is different, therefore, before starting to create such a structure, it is necessary to calculate the required installation depth of the channels. Pipes can be laid vertically and horizontally. The first option is the most expensive, since the channels will have to be dug using special equipment. You can dig trenches for horizontal collectors yourself, but they will take up a large area near the house.
As for which heating is the most economical, the cheapest types of fuel are gas, heat from the earth (more: "") and the sun. However, it should be borne in mind that the installation of such heating systems is very expensive, so the initial investment will be very high. However, during operation, you can save on fuel, and after some time all costs will pay off.
It is better to prepare a sleigh in the summer, as well as a heating system at home or a summer residence. It is not worth postponing “for later” the solution of this vital issue. After all, autumn colds can come suddenly, and it is important that the weather does not take you by surprise.
Homeowners who have gas connected to the house, and there are no problems with heating and hot water supply, can close this article and go about their business. This article is for people who want to do at home most economical electric heating, but the power allocated to their house (the limit of permitted power) is not sufficient to connect several heating appliances and other household appliances. And the purchase of additional electrical power from power engineers is not possible due to the unreasonably high cost or the physical absence of excess power due to old transformer substations.
What is the most economical and inexpensive heating system with electricity?
Based on many years of experience, we can say that the simplest and most inexpensive way to implement electric heating of a country house or cottage is use of electric convectors. These electrical appliances have positively proven themselves for heating, both residential and administrative or retail space. This type of electric heating has a number of important advantages over other electric heating systems and appliances. Let's look at just a few of the benefits.
1. Best performance and economy
The principle of operation of an electric convector is natural air circulation, when warm air, as less dense, rises above cold air. The air inside the room is mixed spontaneously. This achieves good uniformity and speed of heating, as well as the absence of drafts.
The heating elements of electric convectors have a small mass and thermal inertia, so they heat up quickly. Unlike, say, radiators filled with oil. Therefore, the efficiency of such a heating device is very high, and the power consumption is an order of magnitude less than that consumed by an electric boiler.
Almost all the electricity consumed by the convector is converted into heat. And the thermostat allows you to achieve, because the TEN does not work constantly, but only when the air temperature drops. Those. cyclically.
2. The best indicators for operational safety
Modern convectors contain, which do not heat up above 100 ° C. At the same time, the temperature of the convector body remains below 60°C. The convector does not burn oxygen. And most devices of this type have increased protection against moisture (IP24), so they can be safely installed in bathrooms, bathrooms, dressing rooms, next to the pool, etc. Although, of course, this does not mean that the convector can be watered with water from a hose!
Convectors from leading manufacturers are equipped with a security system that will turn off the heating if the air inlet or outlet is closed. Therefore, convectors can be used in kindergartens, children's rooms, hospitals, etc.
3.Easy to install and operate
The electric heating convector is ready for use immediately after purchase. All that is needed for its operation is installation on a wall or on special legs, as well as inclusion in the mains.
To select the temperature, it is enough to set the thermostat to the appropriate temperature value, and then, just wipe the dust from the case. Unlike installing a water system, convectors save significant money because they do not require piping throughout the house.
4. Small price
The cost of high-quality electric convectors cannot be compared with the cost of an electric water heating system.
5. Possibility of gradual expansion of the system
Convectors can be bought and put into operation gradually, as needed or as funds are available. While water heating requires the purchase of all components at once, which is not cheap.
6. Ability to use energy-saving automation
Very often, the power allocated to a house or cottage is not enough to connect several energy-intensive heating devices. Electric convectors allow the use of additional external automation, for example, the OEL-820 Clusterwin power grid load optimizer, which reduces the overall power consumption and allows them to be operated even with insufficient permitted power limit.
This is very important for a country house. In addition, the load optimizer does not require installation, but simply plugs into the outlet, like an adapter - an adapter. requires a large input power, which cannot be reduced.
7. Insensitivity to mains voltage fluctuations
The heating elements of convectors are not sensitive to mains voltage deviation, which is often found outside the city. Therefore, they do not require an additional voltage regulator.
8. Excellent design and compactness
Heating with convectors does not require space under the boiler room. Convectors have small dimensions and will fit into any interior.
Point 6 will be explained with an example
Under an agreement with an energy sales company, the electric power allocated to the house is 5 kW. At the same time, it is necessary to operate four 1 kW convectors, a 1 kW water heater, and a 1 kW kettle. In total, our electrical appliances consume 6 kW, which exceeds the allocated limit. Therefore, when they are turned on simultaneously, the network will be overloaded and the machine (circuit breaker) will be knocked out ...
However, it is not necessary that all appliances be turned on for heating at the same time. If powerful electrical appliances are conditionally divided into pairs and made so that each pair can have one, and only one electrical appliance turned on, then it is possible to significantly reduce the total power consumption and bypass the limit of permitted power. For these purposes, they use the latest automation - power grid load optimizers. For example, .
You can read more about this device and its operation.
To connect energy-intensive electrical appliances, we will use three OEL-820 CLUSTERWIN load optimizers for the power grid.
Third floor. One large studio.
When the priority convector A is turned on in heating mode, the non-priority convector B is switched off. As soon as the temperature in the left zone of the room reaches the set value, convector A will turn off the heating. The operating cycle of non-priority appliance B starts.
When the temperature in the right zone of the room reaches the set value, convector B will turn off. For some time, depending on the quality of the thermal insulation of the room, both convectors can be turned off. At this time, the temperature in the left zone of the room slowly decreases.
When the temperature drops below the set value, the priority convector A will turn on and start its new working cycle.
Since only one convector can be switched on in this pair of convectors at any time, the total power consumed by the two convectors will never exceed 1 kW.
The total consumption and load on the power grid is reduced by 2 times.
Second floor. Two separate rooms.
Convectors on the second floor, connected to the network via power grid load optimizers, work in the same way as convectors on the third floor. Only each of them heats its own room. At the same time, the total power consumed by two convectors never exceed 1 kW.
Ground floor.
The kettle and water heater are connected to the mains via the OEL-820 optimizer. While the kettle is not in use, the water heater operates according to the temperature set on the thermostat. When you turn on the kettle, the water heater automatically turns off for the duration of the kettle.
As soon as the water boils and the kettle turns off, the water heater will be connected to the network and continue to work. It is preferable if the water heater thermostat is electromechanical. This water heater is also cheaper.
Since one and only one of two electrical appliances can be switched on, the total power consumption of the kettle and water heater will never exceed 1 kW. Therefore, their consumption and load on the power grid reduced by 2 times!
Conclusion: when operating six electrical appliances with a total power of 6 kW, connected via three power grid load optimizers, the total power consumed from the power grid will never exceed 3 kW!
Which of the points of advantages of convectors listed by us should be put in the first place, and which in the last? There is no single answer to this question. But, the ability to choose what is more important in your particular situation is already wonderful!
Which electric convectors to choose?
This is a matter of taste and wallet. It is clear that you should only buy devices from well-known manufacturers, such as NOBO or similar. This is your safety. Pay attention to a function such as self-recovery operation (restart) after a power failure.
Normal convectors are not sensitive to power failures. And those that require a human restart are not easy to use and can cause great damage by freezing the house.

It is known that the most inexpensive heating option is considered to be a gas system. But there are situations when it is not possible to use it, for example, if a gas main does not pass nearby. In this case, heating the house with electricity is recommended. The most economical way can be chosen by analyzing all the options offered. This is what we will do in this review.
Why choose electricity for heating your home: the most economical way
Electric heating system has the following advantages:
Options for electric heating of a private house
Such a heating scheme involves the use of various types of equipment.
Boiler Application
Selection of IR panels
When deciding how to heat a house with electricity economically, you can consider the option of installing infrared structures. Such products do not heat the air inside the rooms, but various objects. If, in the version with a boiler, the air masses move upwards and then cool down, then in this case the hot streams are directed to the floor.
If thermostats are added to infrared devices, they will work more efficiently. One controller is enough to control three heaters. This equipment is economical in the process of application, but expensive in terms of installation and construction costs. IR devices consume a small amount of electricity. In addition, they rationally distribute heat. They can perform spot and zone heating. Even after the design is turned off, objects generate heat for a long time.
Installation of such equipment can be done independently. The infrared system is used both as the main type of fuel and as an additional one. The advantages of the option include a long service life, up to 80 years.
Heating a house with electricity is also done using infrared. This is an economical and effective tool. This design is not afraid of unexpected power surges and does not break with minor damage. You can install such a device under various floor coverings except for parquet. Infra-red rays heat only solid objects, therefore, when the floor is heated, the elements themselves do not heat up.

Ask a Question“Infrared heaters can be placed anywhere. They are installed on the floor, on the ceiling or even behind some objects.
Benefits of convectors
When choosing the most economical electric heating without a boiler, it is worth exploring the possibilities of convectors. According to manufacturers, it heats the space with high quality and at the same time spends a small amount of electricity. The main advantage of the device is that its installation is simple.
It takes about two minutes to warm up the heating element, which is much faster than when heated with water devices. The advantages of such structures include:
- low cost of equipment;
- fire safety;
- the heating system can not be completed immediately, buying additional radiators as needed;
- modern design;
- uninterrupted operation even with sudden voltage changes;
- small sizes.
This method maintains the desired ratio of humidity in the room and does not destroy oxygen. Excellent technical properties and excellent power indicators make it possible to use electric convectors for heating both large and small private houses.
The main element of the design is the heating element, which converts the energy of electricity into heat. The principle of operation is air convection. In this case, the cooled streams penetrate into the slots in the lower part of the body, and then exit through the upper holes. The convector can work alone or in a system controlled by a temperature controller.
