Before starting the article, it is worth noting that the most effective at the moment is considered to be gas system heating. But if, for some reason, it is not possible to install a gas boiler (for example, there is no gas main in the country), you should pay attention to such an option as economical heating a private house with electricity, using certain schemes for organizing heating.

As an alternative, electricity is a safer solution, moreover, the installation of this equipment does not require any additional permits. In addition, you can easily make electric heating of a private house with your own hands. The disadvantages include, perhaps, high bills for consumed electricity.

It should be noted that electric heating, made independently or factory-made - is the most reliable, environmentally friendly and comfortable way to heat a home. This equipment does not require maintenance, is easily regulated and can be automated, so it is much easier and safer to heat a house with electricity. The design does not include quickly failing elements. No need to constantly monitor the fuel level and sensors.

Moreover, electric heating of a private house has the following advantages:

1. Ease and simplicity of installation. Installation does not require special qualifications and expensive tools. The equipment itself is quite small in size and it does not take much time to install it. All devices are quite easy to transport. This equipment does not require a separate boiler room or chimney.
2. Safety. The electric heating system does not emit combustion products and carbon monoxide. Even during disassembly or breakdown, no harmful substances are released.
3. Low initial investment. There is no need to make any special permits, prepare a project and invite special services who will approve the installation.
4. Reliability and quietness. Electric heating does not require regular checks in specialized services. During operation, the equipment does not produce any noise due to the absence of elements such as a fan and a circulation pump in the system.
5. High level of efficiency. Even during severe frosts heats up the house quickly enough. Electric heating is necessarily equipped with a special system that allows you to adjust the temperature in each room separately. This makes it possible to significantly save money during the heating season.

A significant disadvantage of this equipment is a large power consumption. Electricity prices in some areas are quite high, and this option for heating a home may not be profitable.

Another significant disadvantage is energy dependence. Heating the room is simply not possible if the electricity is turned off.

Unstable voltage in the power grid can also be attributed to the minuses, this problem is especially acute in rural areas. To resolve it, it is recommended to purchase your own generator, but this will entail additional cash outlays.

If you nevertheless decide on economical heating of a private house without the use of gas, that is, electric heating, then you will need to take into account the general condition and power of the electrical wiring. A large private house for such purposes will require a three-phase network. It will be necessary to clarify the allocated power for the house, and how much of this power can be given to heating.

Types of electric heating systems and their features

Any electric heating system of a private house can be built according to two principles:

• Direct. Heating of each room is carried out by devices that are powered directly from the network.
• Indirect. With this principle, a coolant is used that heats the radiators installed in the premises.

There is enough a large number of opinions, which electric heating is the best option for a private house. Most adherents of the indirect method of heating the house as the main argument give a long cooling process in the system, which gives sufficient advantages during the shutdown of the boiler. Others, supporters direct heating, speak of lower costs during the acquisition and installation of equipment.

Consider a variety of electric heating systems in order of increasing cost of investments:

• fan heaters and convectors;
• heating with infrared radiation;
• plinth electric heaters;
• warm floors of cable and film type;
• standard water system equipped with electric boiler and radiators.

Installation of wall-mounted electric convectors is carried out in those areas where, as usual, water heating radiators are installed - near cold walls and under windows. Fan heaters usually have forced air injection and a mobile design. They can be located in the most convenient places. This type electric heating is the cheapest, but at the same time less efficient.

The heating system based on infrared equipment is more efficient. These devices, mounted to the ceiling, heat all surfaces, from which the air is subsequently heated. Plinth convective heaters, which are located around the perimeter of the room, proved to be quite effective. But such a design will require additional costs due to the fact that it will need to be installed instead of skirting boards.

Such a proven method of electric heating as underfloor heating is very popular. This method basically uses a heating film, electric cable mats or a heating cable that can heat a fairly large room. The design itself is quite inexpensive, but installation under a screed or coating can cause a serious blow to your budget. This method of heating is the most economical, moreover, it gives pleasant warmth and creates a feeling of comfort.

All of the above methods have a significant disadvantage, their work is possible only in the presence of electricity. If the cost of electricity rises, it becomes possible to bring natural gas into the house, or for some reason you need to change the energy source, the previous equipment may be useless.

To prevent such a misunderstanding, it is recommended to install an electric boiler and a standard water system with radiators for heating. If there is a desire to change the energy source, the money will need to be spent only on a new source of heat.

In a small apartment, cable underfloor heating is an ideal option, their degree of comfort is beyond praise. Cheaper methods also have a right to exist. But in more severe colds, their capabilities may not be enough and it will be cooler in the rooms.

In a large apartment, the best option would be to install radiator independent electric heating or warm water floors.

It would be much more difficult to choose the best option if it were not for the price of the energy carrier. But apartment owners also face the problem of a limited consumption limit (about 3-5 kW).

It is recommended to think about this in advance, as soon as the organization of electric heating of the apartment is planned. It is necessary to carefully study the contract for the supply of electricity, which indicates this limit, this contract may also stipulate that heating a home with electricity is prohibited.

It is somewhat easier to organize electric heating in a private house than in an apartment. The power consumption limit is much higher, it is possible to check the wiring and, if necessary, put it in order, starting with the power line. From the list above, the owner of the cottage, the most successful option would be water system heating with electric boiler.

This is quite easy to explain: it is necessary to ensure the use of various energy sources, and not just electricity. Based on this, you will need to select the boiler, mount it and assemble one or two-pipe system.

Design characteristics of electric boilers

Modern boilers operate on three principles of heating the coolant:

• heating elements;
• electrodes;
• based on magnetic induction.

The first option is the most common. The coolant from the system enters the boiler, where it heats up with the help of tubular heating elements and flows back into the heating system. This type of equipment is safe, functional, and also has built-in automation that controls the temperature of the air in the room and the coolant.

Electrode boilers work on a completely different principle. In this device, the heating element consists of a pair of electrodes to which a high voltage is applied. The coolant is heated due to the fact that the electric current moves through it from one electrode to another, after which the coolant enters the heating system.

Important! in boilers of this type there is no electrolysis process (due to which there is no scale formation) due to the use of alternating voltage with a frequency of at least 50 Hz.

The intensity of use affects the ability of the electrodes to heat up, as over time they become thinner and cease to heat the house to the extent that it is needed. In electrode boilers, replacing the electrodes is a standard procedure.

The device of induction boilers is more complex, although they are structurally more attractive. This type of boiler does not have heating elements to which we are accustomed. The heat exchanger, which is part of the magnetic circuit, uses a powerful magnetic field to heat the coolant passing through it into the heating system.

Electric heating of a country house, in the form of indirect heat transfer, has serious advantages over gas and air heating: hot water electric boilers are quite reliable, do not require a chimney and have a high efficiency. The disadvantages of these devices, perhaps, include the requirements for a stable voltage of your network, as well as the presence of good wiring.

Water installation heating system with an electric boiler requires a serious initial investment, especially if a third-party organization is involved in this, which will be involved in the project of installing, configuring and balancing the system. It is also worth additionally allocating money from the budget for the maintenance of this heating system, which includes checking the operation of valves, periodic flushing of radiators, and so on.

How to save electricity?

Follow these tips to make electric heating in a private house more economical:

• use multi-tariff metering of electricity, since at night the tariff is much lower than during the day;
• use non-electric heat sources during business hours;
• install thermostats in the rooms;
• give preference to underfloor heating systems;
• traditional advice: try to make the maximum insulation of the house or outer wall apartments.

Do not neglect the means of automation, which can help reduce the temperature in unused rooms. And in general, you should not reject any means that will help you reduce energy costs.

Create a project optimal system electric heating. For example, a small one-room apartment can heat an electric boiler (provided that the heat loss is quite small). But in the house with large quantity rooms, he may no longer be able to fully cope with the task.

In this situation, the best option would be to install a convector system with thermostats that will control the climate in each room. infrared panels optimal solution will be for outbuildings where there is no need to maintain a constant temperature.

Thus, we reviewed all the popular methods of electric heating and concluded that heating a house with electricity is not only the most economical way but also the safest. Each method has a rather large list of advantages - environmental friendliness, no need for fuel, noiselessness and ease of operation. But given the cost of electricity, do not count on any economic effect. Therefore, it is recommended to insulate the dwelling as much as possible to reduce heat loss.

Heating is the largest energy expense in most homes. It accounts for from 35 to 50% annual electricity bills.

Most effective method reduce the size of these bills - reduce the use of energy for heating.

The heating system replaces the heat that is lost through the walls, windows, floor and ceiling of your home.

Ways to economically heat a private house

The amount of energy required to replace the lost heat depends on four factors:

1. location of the house (in colder regions, consumption is higher);
2. the size of the building;
3. energy efficiency at home;
4. energy efficiency of the heating system.

The first factor is the main but it does not depend on you. The colder the weather outside, the more energy is required to maintain a comfortable temperature inside.

important and house size. A spacious room contains a significant amount of air that needs to be warmed up. Therefore, a large house requires large heating costs.

A great opportunity to save energy and money is to improve the energy efficiency of your home and its heating system. There are several ways to do this:

• choose the optimal type of heating system;
• improve facade insulation;
• repair the heat distribution system (air ducts and pipes);
• eliminate heat leakage through doors, windows and various cracks.

How to perform facade insulation

Thermal insulation of the facade in the form of its insulation is the main protection of the house from heat loss through the building body. Therefore, it is very important to insulate the largest part of the house in terms of area - the walls of the facade. Insulating materials reduce heat loss by providing a barrier between inside home and significantly different temperatures outside.

Used in houses different types isolation. The most common ones- polyurethane foam, polystyrene foam and fiberglass.

Polyurethane foam

Foam insulation is spray or injection foam.

• spray foam in a liquid state, it is distributed in the open spaces of a new house design. After that, the foam expands, fills the cavity and solidifies.
• injection foam pumped into existing cracks, crevices or other voids in walls. This makes this polyurethane foam indispensable for repairing the insulation of existing homes.

Styrofoam

Styrofoam happens with open or closed cells.

• Expanded polystyrene with open cells very light and flexible. When the polystyrene foam is foamed, the gas inside the cells escapes through holes in the cell wall. This process contributes to the creation of a light and flexible shape that compacts as it cures.
• Closed cell expanded polystyrene has a much denser and heavier structure. It forms a dense surface that is more resistant to weathering and temperature changes.

Fiberglass

Fiberglass is made from soda, limestone, sand and crushed glass and is supplied in slabs or rolls. It is placed in unfinished walls, floors and ceilings between pins, beams and crossbeams. Due to its fibrous structure, this material is excellent keeps air inside and prevents heat loss.

Photo 1. A piece of fiberglass. It is one of the most popular home insulation materials.

Efficient boilers for space heating

In order to efficiently and economically heat a house, it is necessary to choose high-quality heating equipment. Most often, boilers are used in this role.

You will also be interested in:

Condensing gas

Boiler operation with condensing gas allows you to use all the energy released during the combustion of gas. All boiler systems distribute heat to hot water, which gives off heat by passing through radiators or other devices in rooms throughout the home. The chilled water is then returned to the boiler for reheating.

In a conventional boiler, the heating system circuit is heated during the combustion of natural gas. condensing boiler uses the energy available in the products of gas combustion. These products contain water vapor. As the steam cools, it condenses and releases heat. The water in the heating circuit is heated by this energy. The evacuation of water released during condensation (condensate) is carried out through the network Wastewater.

Important! Natural gas is the most affordable source of energy. Therefore, the cost of operating a condensing boiler will be the most profitable.

Such a boiler is easy to operate, consumes less fuel than a standard gas boiler, and has efficiency, often exceeding 100%.

Pyrolysis

The pyrolysis boiler runs on solid fuel. In this case, not only the firewood itself is burned, but also the gases that are released in the process.

So Action efficiency such boilers - up to 90%. Firewood or special pellets made from dried biomass burn in one chamber, releasing pyrolysis gas.

Under the influence of high temperature, the gas enters another chamber through a special nozzle, in which it burns, mixing with oxygen.

The thermal energy released in this process is much higher than in conventional boilers and burn time is much longer. So pyrolysis boilers called long burning boilers.

Such gas generating boilers do not depend on the presence of the main gas pipeline, and can most effectively use purchased fuel.

solid fuel

The simplest boiler is a wood or coal boiler. He completely autonomous, and does not require any connection to the gas pipeline or electrical network, nor the cost of paying for gas and electricity. Just a standard body is enough, consisting of a firebox (or combustion chamber) and a blower, and ordinary firewood.

Firewood is burning in the firebox thanks to the air that is supplied through the blower. In this case, thermal energy is released. It heats a steel or cast iron heat exchanger in the form of a coil, located in the furnace, and increases the temperature of the coolant. Hot water gives off heat when it passes through the heating system of the house. The chilled water is then returned to the boiler for reheating.

Electric boiler

Work electric boilersimilar to the operation of other boilers: the water in it is heated, and then circulates in the heating system circuit and radiators.

Water is heated in these boilers via electric current . It provides high performance and excellent heating rate.

In addition, the installation of an electric boiler does not require large expenditures for the installation of expensive equipment, the presence of a chimney and a large room.

Warm floor

Underfloor heating is the most old form central heating . Even the Romans used an underfloor heating system that warmed buildings and baths. Today's system floor heating is gaining more and more popularity in Russia.

Underfloor heating is a system that heats a house through a heated floor covering. Exists two types of such system. In the first type warm water heats the floor, passing through the pipeline laid under the floor ("wet" system). In the second floor becomes warm with electric coils placed under it ("dry" system).

Concrete floor slabs heat up, and heat is radiated from under the floor into the room. "Wet" system can be connected to gas boiler for water heating. This will help you save a lot on cheap gas fuel.

Attention! For this type of heating massive building work is required. Therefore, its installation is best done during the construction of the house.

Infrared heating is one of the most economical ways

The infrared spectrum is part of the electromagnetic spectrum. This form of radiated heat is the most basic. It's the same 100% natural heat type, which radiates and absorbs the human body daily.

Photo 2. Installation of infrared heaters under the roof of the house, this installation method allows you to completely warm up the room.

The peculiarity of infrared radiation is that it heats objects and people in its path. without heating the surrounding area. It does infrared heating much more efficient than convection. The convective heat generated by conventional radiators and central heating systems only heats the air.

Warm air is distributed throughout the room, circulating uncontrollably and leaving objects in the room cool. Infrared heating radiates direct heat and heats everything. This type of heating brings long-lasting, comfortable warmth to the house, consuming less energy.

Infrared heaters can provide targeted heat anywhere, no matter the distance. This means that there is no need to spend electricity to heat a room of any, even the largest area, and heat is not lost due to air circulation.

Solar collectors - cheap and economical

Solar collectors use heat sunlight for heating water which then goes inside the building. They consist of a panel of heat-absorbing material into which mixture of water and antifreeze to collect heat. This mixture then heats the water in the hot water system, so solar collectors must be integrated into existing system heat distribution.

Photo 3. Solar collectors installed on the roof of the house. Devices must be placed at a certain angle.

Such thermal systems can be useful not only in warm climates. Even a small increase in water temperature dramatically reduces the amount of energy needed to heat it. Solar collectors create favorable conditions to start any heating system. It means that less energy is used overall.

Most have an impressive area and due to the fact that Russia is a non-resort country in which all year round summer reigns, this same area needs to be heated somehow in the winter. For these purposes, there is a whole arsenal of diversity, but due to the large volumes, many options hit the pocket hard. If approached correctly this issue, then it turns out that electricity is the most economical way.

Types of electric heating of a private house

Heating by electricity can be divided into several categories: spot, general, combined. Below, the varieties and principles of operation of electrical appliances of such a plan are described in detail.

Spot heating with space heaters

The domestic market can offer a huge range in the segment. The pricing policy will allow you to choose models of both economy class and premium units. In order not to get confused in the options, they are divided into subgroups:

• . Based on the work of needle or x-shaped heating elements.

The body of these devices is mainly made of of stainless steel, but there are models that are made of glass or stone. The geometry of the box suggests the presence of holes for air intake at the bottom and a grate for ejection of a hot stream at the top.

Such devices are equipped with all kinds of regulators. Which provides complete protection against overheating, tipping over, short circuits, etc. Some instances have additional privileges: electronic control, touch screen, remote control, moisture protection, dust protection, and more.

Installation can be done on the walls, or with the help of wheels.

• Thermal fans. Very comfortable and easy to use, have small dimensions and low weight. The standard power that most 2 kW fan heaters have is enough to heat small room in just 10 minutes.

The device works thanks to a fan that drives air to a heated coil, which, in turn, heats the flow and transfers it to the room. Such devices have a number of disadvantages, such as: heats while blowing, high power consumption.

In stores you can find devices with additions in the form of an ionizer, sleep timer,. Such electric heating is the most economical without.

• . They have a lot of advantages, which ensures comfort during their operation. The excellent directed heat dissipation generated by the infrared emitter will be able to fully warm you not only indoors, but also outdoors.

The design is a concave aluminum reflector with a special heat-repellent coating that focuses and directs all thermal energy in a certain direction. There are models that have a moving base that provides heating at 90, 180 or 360 degrees.

• Oil heaters. An old acquaintance who managed to warm more than one generation of families. Its ability to heat up more than 100 degrees, while consuming an acceptable amount of energy, has won many fans. The mineral oil that is inside the heater does not expand when heated strongly with a heating element, which increases the operating temperature.

Description of popular models and systems for heating

To fully determine the most profitable models, you need to analyze a whole ton of material about the characteristics and performance indicators. Of course, there are a large number of TOPs on the Internet that describe the most popular models of heaters in their segment (here is one of the best TOP 10 electric heaters), but in fact the choice can be limited. This is done according to the following criteria:

• Required power;
• Mounting method;
• Safety protection class;
• Required additional features;
• Case dimensions;
• Design;
• The budget for the purchase;

Having made a list, you can easily choose the appropriate option.

Overview of electric boilers for heating private houses: prices for the most popular models

Here is a list of the most popular manufacturers who have distinguished themselves by excellent quality and excellent performance. Heating in a private house with an electric boiler (cost in the table below) is considered an alternative in the absence of a gas main.

Heating the house with electricity. The most economical way for you

All explanations about savings will be considered on the example, which has an area of ​​​​100 m2.

What happened in the end? The total cost without solar panels is 70,000 rubles. Power consumption 14 kW / h, per day of operation of two boilers at outdoor temperature-10, consumption will be about 90 kW/day. The cost of a kilowatt of light is 5.38 rubles, which means 90 × 5.38 × 30 = 14526 rubles per month. If we count with installed solar panels, then the amount of expenses will be 11,500 rubles.

This is one of hundreds of options, what to choose is up to you.

Note! To understand how to heat a house with electricity economically, you need to know some tricks. One of them is the installation of a three-tariff meter.

Overview of the latest solutions in electrical heating systems

It can be immediately noted that all the latest developments are very expensive, but they have a good tendency, they quickly pay off.

• Solar collectors that heat water. Such panels are placed on the roofs of houses from the sunny side. They show themselves very effectively in sunny regions. They have a fairly high efficiency and the maximum level of environmental friendliness. And the downside is the impossibility of operation in the dark. In most cases, they are installed as .

• Solar systems. Heat pumps that suck heat from the environment (air, ground and water) and transfer it to the heat carrier. Great option heating, but very costly at the initial stage. The equipment takes up a lot of space. Payback period from 2 years.

• Electrode boilers designed for (reviews from owners and approximate prices there are many forums and sites). A small device in the form of a pipe, heats up water, passing through itself. The coolant must contain salt. Charged particles accelerate to tremendous speed inside the pipe and heat the water with their friction. A very efficient technology. A negative nuance is the discrepancy between the power and the heating area declared by the manufacturer.

conclusions

Heating a house with electricity is the most economical way only if you approach it wisely. Having invested more money when installing units, you will save a tidy sum in the future. Moreover, in today's world, where the level of pollution is off scale, the use of environmentally friendly technologies is a very important point both for you and for future generations. Remember this.

What's happened economical heating? The one that was cheap to purchase equipment and install? Or where the cost of each received kilocalorie of heat is low? As a rule, they mean the second. However, in addition to the cost of fuel, there is also the cost of maintaining equipment and it is often preferred to hush it up. Can you name economical system heating, in which the specific cost of a unit of thermal energy is unprecedentedly low, but investments in equipment are so high that their payback period exceeds the service life?

Which house has the most economical heating

Answer: in the house that is best insulated. No matter how much effort and money we invest in engineering communications, if the building is poorly insulated, we will still incur unreasonably high heating costs. First of all, you should pay attention to the thermal insulation of enclosing structures: external walls, roof, floor of the lower floor, windows and doors.

The ratio of heat loss through various building envelopes of an average individual residential building

In addition to the minimum requirements for thermal insulation, the current Russian standards also contain recommended parameters. The minimum allowable characteristics of enclosing structures are determined by calculation and depend on the climatic conditions of the area. Example: for the climate of the Moscow region, the thickness of the outer wall of gas silicate blocks with a density of 500 kg / m2 in 40 cm is sufficient, but to achieve the recommended indicators, additional external thermal insulation with mineral wool at least 8 cm thick is required.

When insulating a house Special attention give to "cold bridges": concrete lintels, ends of floor slabs, reinforced belts, window slopes etc.

How much does comfort and personal time cost

Oddly enough, the efficiency of heating is a somewhat relative concept. For example, the owner of a private house lives in a non-gasified, but wooded area and has the opportunity to harvest firewood very cheaply in the volumes he needs. Fuel costs, even with a primitive heating system with an ancient, monstrously voracious CFM and registers instead of batteries, will be extremely low. However, the owner will have to work hard to prepare firewood, do not forget to periodically load it into the furnace, clean the boiler, take out the ashes, put up with uneven heating, the impossibility of fine adjustment. The homeowner can invest in modernizing the heating, purchase an automatic pellet boiler, and make modern wiring. The consumption of wood fuel in kilograms (tons) will decrease by three times, but the cost of each kilocalorie will seriously increase. In this case, what is the most economical heating - wood or pellet? At a specific price, kcal is undoubtedly the first. In terms of quantitative fuel consumption - the second. How to evaluate free time, which the owner of the house will have after switching to pellets? In addition, a more advanced system will create high thermal comfort in the premises, and this, after all, is also worth something.

The cheaper it is to heat a house

If we discard the possibility of harvesting firewood for free and focus on average prices Central Russia Natural gas has been the cheapest fuel for many years. It also allows you to fully automate heating, modern gas boilers require only preventive maintenance once a year. Only electric heating can boast of the same properties, but it costs many times more. Even for Western Europe, where the price of gas relative to other types of fuel is much higher than in the Russian Federation, the most economical home heating is gas.

The table reflects the comparative cost of thermal energy for prices in the Moscow region. And if for gas, diesel fuel and electricity in other regions the cost ratio will be similar, then the prices for pellets, firewood and coal can vary greatly depending on local conditions.

For gasified area heating natural gas there is no alternative. If there is no gas pipeline nearby, you need to calculate what is ultimately more profitable. Laying the highway is not a cheap pleasure. The initial investment in equipment also matters.

The ratio of purchase and installation costs heating equipment.

As you can see, the initial costs of electric heating, especially direct heating, are the lowest. The level of comfort and safety is maximum, it is easier to solve issues with electricity than with gas, there is no need for a chimney. The main thing that electrical power enough. It is precisely because of the low start-up costs and ease of installation that buildings built on the principle of a “passive house” (there are such in our area) are increasingly heated with electricity. Based on the combination of initial and operating costs, it turns out that in this case the most economical is electric heating. We repeat that this applies only to modern, well-insulated buildings with low specific heat losses in the absence of a gas pipeline.

Heat from alternative sources

The statement that the most economical heating comes from alternative sources is not true. Transfer pumps liquid media in geothermal and solar systems, consume electricity. And it costs a lot of money. Today, heating with gas at our prices is still more profitable than installing a heat pump. And there is no need to talk about any serious use of solar collectors in the domestic climate. Today, a more justified solution is the creation of a combined heating system: a heat pump designed for 70% of the required power, and an additional solid fuel (pellet, electric) boiler or fireplace, which gets the missing 30% during severe frosts. Solar collectors are usually used only for heating hot water. tap water. Recall that the cost of "alternative" equipment is still so high that in the conditions of the Russian Federation it often does not even pay off during its service life, if we compare its performance with wood heating.

Using the temperature difference between the two media, the heat pump draws energy from the environment. However, for the constant circulation of the refrigerant and the selection of energy from it, rather powerful pumps operate that consume electricity.

The most economical heating scheme

In water heating systems, in addition to the type of heat generator (boiler), efficiency also determines the type of heating devices, the heating scheme, the nature of the wiring, and the presence of automation:

• Among heating devices, heated floors are the most economical.

Underfloor heating is more economical than radiators due to a more even distribution of temperature in the room

• The most economical and comfortable water heating scheme is collector (radiation). Not cheap, but extremely comfortable. It is followed by a two-pipe, it can be considered the golden mean. At a moderate cost, it is quite effective. A simple one-pipe circuit does not allow adequate regulation of the heat transfer of devices.

Collector wiring allows you to best balance the hydraulic resistance of the circuits, adjust heat flows

• Automatic control heat flows at all levels (boiler, distributors, appliances) also significantly reduces fuel consumption.

Because of the low fuel prices so far, we are accustomed to squandering thermal energy. And in rich, but very economical Germany, it is hardly possible today to find a radiator without a thermostat.

• The most economical heating of a private house is the one that is correctly calculated and competently, professionally designed, installed and configured.

The more complex the equipment, the more you can save by setting it up correctly. This is not an easy task and requires specialized knowledge.

Economic heating with electricity - myth or reality

The Internet is full of commercials and articles about "innovative most economical electric heating boiler" and "super electric batteries for economical heating" and other miracles. All this is nothing more than cunning marketing barkers that have nothing to do with reality. In fact, the efficiency of all electric heaters, regardless of their type, approaches 100%. Treasured savings simply nowhere to take. There are only two real ways to reduce the cost of heating with electricity:

• Install a two-tariff meter and heat mainly at night. From 23.00 to 07.00 on weekdays and all weekends, depending on the region, electricity costs 1.4-2.1 times cheaper. Having invested in a heat accumulator of sufficient volume, you can stock up on cheap night energy for the day.

• Use underfloor heating to the maximum: water, with heating from a boiler, and direct heating - cable, film. The savings are relatively small, 4-6%, but in the end, a round sum will come up.

The most economical heating boiler

• Gas. Modern condensing boilers with modulating burners consume the least amount of fuel. Savings compared to standard counterparts without condensation - 11%, this is a lot. However, it should be borne in mind that the advantages of such boilers can only be fully realized in low temperature system heating, it will match optimal mode boiler operation. Initially, underfloor heating is low-temperature, but the number of sections in the radiators will have to be almost doubled. We can safely say that the most economical heating of a private house is gas, low-temperature, based on a condensing boiler, built according to a beam scheme.

Condensing boilers utilize the potential energy of flue gases, in particular steam

• solid fuel. Pellet and wood pyrolysis boilers consume the least wood fuel.

• Electricity. As already mentioned, “the most economical electric boiler for heating” is a myth, the efficiency is the same for everyone.

• Liquid fuel. The most economical liquid fuel boiler - on used engine oil. The only question is where to find a permanent source of this almost free type of fuel.

Universal oil burners capable of operating on diesel fuel, biofuel, heating oil (petroleum heating oil) and mining

In conclusion, we emphasize that the creation of an effective and comfort heating requires a professional approach. You can try to do everything with your own hands, but for this you will have to at least learn the basics of heat engineering and hydraulics. If it is possible to devote some of your personal time to these sciences, the selection of equipment and installation work no, we advise you to entrust the design and installation of engineering communications to experienced professionals.

Video: economical home heating

Owners of private houses for various reasons choose heating with electricity. Unfortunately, of all existing methods, it is considered the most expensive. Therefore, the question of how to reduce the cost of heating a house with electricity is more relevant than ever. We will consider the most economical way in more detail by comparing some types of heating systems.

Advantages and disadvantages of heating with electricity

Often, houses built on private plots are not connected to energy networks: gas, solid fuel. In such cases, the organization of heating with the help of electricity becomes the only way out.

For example, many people install all kinds of heaters, stoves in the house, if the main system is not working yet. Do these methods have clear pros and cons? Let's look into this in more detail.

Heating private houses with electricity: undeniable advantages

1. Ease of installation of electrical heat sources.
2. The ability to quickly adjust the temperature to the desired level.
3. Saving energy consumption.
4. Mobility of heating sources (in case of using mobile radiators).
5. The ability to choose the type of convector for the interior of the house.
6. Environmental friendliness - oxygen is not removed (not burned) from the space of the room, there is no danger of harmful emissions.

Cons of heating from the mains

1. The high cost of electricity services.
2. If you need to create high voltage, you will need to purchase and install an energy distributor.

Advantages:

1. Such devices are compact.
2. Light in weight, affordable, but have a high heating power. They can be grouped, include only one or all at once.
3. And one of its main advantages is resistance to voltage drops, which is especially relevant for houses with old wiring.

But at the same time, the electrode system has disadvantages:

1. unstable power level;
2. extreme dependence on the composition of the conductive substance and its temperature;
3. requires strict adherence to the proportions of the solution and its purity;
4. incorrect "reaction" to adjustment and automatic control.

User reviews of electrode boilers:

Sergey, Perm: Each heating season requires new electrodes, which is considered a very laborious task. The manufacturer claims that if you adhere to all performance characteristics, the device will last a long time.

Natalia, Riga: I purchased the Vulkan-25 model. We often have to dismantle the boiler and clean it. If the plates are not cleaned in a timely manner, the thermal conductivity decreases. The manufacturer recommends first of all to pay attention to the quality of the coolant.

Induction heating boilers

If the question arises of how to heat a house with electricity economically, then this is one of the best options. Today it is the most popular and technically perfect type of electric boiler.

It works like this: in the center of the device, a primary winding is installed, capable of passing an electric current, which provokes voltage in the secondary winding section. It, in turn, consists of a circuit of pipes with a coolant. Due to the fact that there are no vulnerable nodes in such a device, the conductors of electricity do not come into contact with the heat-conducting carrier in any way.

The induction boiler can work stably for several decades! This is an economical device - it can be used to reduce energy costs by up to 40%, when compared with a heating element or electrode "brother".

Note! The device has only three conditional drawbacks - noise from small vibration, the massiveness of the design itself and its relatively high price.

Heating a house with electricity: the most economical way is infrared

Along with the boiler heating system, the infrared method is especially popular today. Special heating plates are installed in the house, in which the emitter draws in electricity and converts it into an infrared wave, and then transmits it. The waves from the heater are in continuous motion until they "collide" with some opaque object.

Plates are usually fixed on the ceiling or walls. However, it should be understood that it rarely acts as the main heating system for a large private house and is more often used as an addition.

Infrared waves quickly fill the room with heat, and then automatically turn off - this is possible thanks to a special independent system automatic control.

Note! This type of home heating with electricity is the most economical way, because it does not use more electricity than necessary.

This option has only 2 drawbacks:

1. Expensive equipment (but at the same time it consumes electricity economically!).
2. Strict direction of heating from the plates to the nearest parts of the room.

Convector heaters

These heating devices are similar in function to conventional radiators - convectors heat up themselves and transfer heat through the air. However, there is no coolant inside them, therefore pipes are not required for them. Instead of a coolant, heating elements are built into the convectors (the advantages and disadvantages of this element were mentioned above), and cold air is taken in through the bottom of the device.

One of the essential advantages of the equipment can be called quiet operation, which is especially important for those who spend most of their time at home. But convectors also have a drawback - this is low efficiency. Electric convectors absorb a significant amount of electricity.

Warm floor

These electrical systems work on the basis of conductors with a resistor, through which an electric current passes, due to which they are heated.
