Electric heating of a private house: pros and cons, options. What is the most economical heating in a private house and how to make it even cheaper

Bringing electricity to the house the task is real and less costly than gasification. Therefore, many people think about heating with the help of electrical devices.

This type of heating is convenient: does not require bookmarking and filling of fuel, changing gas cylinders. And if desired, it can be automated.

Features of heating a house with electricity: what is the most economical way

There are many ways to heat a house with electricity.

Electric boilers

Transfer of energy to the heat carrier heating electrodes. Hot water enters the pipes and radiators distributed throughout the premises, and thus the building is heated.

Coefficient useful action electric boilers is high, some models reaches 99%. Heating of the coolant starts immediately how the boiler is turned on.

Advantages of such heating:

• affordable prices;
• low cost of installation;
• no need for a separate furnace;
• simple and reliable device;
• no open flame;
• environmental friendliness: no emissions, no air duct needed;
• minimal maintenance;
• remote control and automation possible;
• overheating protection and emergency shutdown.

Heating Disadvantages:

• heating costs due to the cost of electricity;
• the risk of power outages;
• high power requirements;
• hard water forms scale on heating elements.

Important! Electric heating is considered the most expensive ( 1 kW is 7.5 times higher than when heating with main gas). In addition, the capacities allocated to private households are not enough for heating with electricity.

Scheme

The electric boiler is the central element. The heating scheme usually includes:

• pump;
• expansion tank;
• collector;
• a number of taps (drain, balancing) and valves (distribution, air);
• filter;
• pipes;
• radiators (batteries).

Installation

At the beginning read the instructions to the equipment.

Installation of the heating system is carried out in the following sequence:

1. installation boiler;
2. installation expansion tank;
3. installation collector;
4. organizations security groups;
5. inclusion in the scheme pump;
6. installation devices to improve the system(control devices, valves, cocks);
7. wiring pipes;
8. installation radiators.

General principles of saving when using electric boilers

The liquid coolant does not cool down quickly. And:

• Select economical model electric boiler.
• Switch to a two-tariff electricity meter and use the heating boiler mainly during the day with a low cost of 1 kW.
• Integrate a heat accumulator into the system, which accumulates heat at night and releases it during the day, when the price of electricity is higher.
• Qualitatively warm up the house.

TENovy electric boiler

Common options for electric boilers for heating:

1. heating elements;
2. electrode;
3. induction.

The heating boiler has heating elements inside - heating elements in the form of bent metal tubes.

They heat up themselves and transfer energy to the coolant. If the heating elements are not immersed in liquid, they may burn out.

Heating benefits:

• heat the house in the presence of only electricity;
• there are models on the market that can be used with the electricity capacities allocated in Russia.

Cons of heating:

• the most expensive heating option;
• requires maximum power;
• efficiency decreases over time.

The remaining options are similar to the general recommendations described above. for liquid systems electric heating.

Induction boilers. How much does the equipment cost?

The heat transfer fluid heats up magnetic field , which is produced inside such a boiler. The two main components of the device: coil and core containing water.

Photo 1. Induction electric heating boiler. It is a small bottle, takes up little space.

The energized coil creates a magnetic field that heats the core, which transfers energy to the coolant flowing through it. Since the coil does not come into contact with water, the coolant is not energized.

Advantages of heating with an induction boiler:

• Reliability: work for years without repair.
• They are considered economical among electric boilers.
• Small dimensions.
• There are no special requirements for the coolant.
• Low inertia. Energy costs go to the initial heating of the water in the system, and maintenance is no longer expensive.
• Easy installation.
• Possibility of electronic control.

Cons of heating with an induction boiler:

• Difficulties self repair.
• The main disadvantage of induction boilers is the cost. If the prices for heating elements electric boilers start from 3-4 thousand rubles, then this option will cost already more expensive than 30 thousand rubles Although some sources state that the difference between these types is from 2 times.

Savings when using induction boilers

Achieved through the principle of action . More economical than heating elements and are considered profitable in operation, especially in the presence of high-quality automation.

For heating with an electric boiler, economical models are selected and use the listed cost reduction opportunities: high-quality insulation, the presence of a heat accumulator, a two-rate meter and heating of the coolant in the cheap period of the day. This will save on electricity heating.

How to cheaply heat a private house with other electrical appliances

In addition to the methods described above, there are more innovative options for heating homes with electricity.

Infrared equipment - will heat the room economically

Manufacturers of similar equipment effective and safe for all living things, electromagnetic oscillations are called, which follow the visible red part of the middle spectrum (infrared rays). Wavelength from 6 to 20 µm, according to different sources. It is this interval that is used in the devices infrared heating.

Photo 2. Installation of infrared heating: special films are attached to the ceiling, which radiate heat.

The device does not heat the air in the room, but only the objects to which it is directed. And they already transfer heat to the surrounding air.

Variants of similar equipment for heating:

• infrared film;
• wall panels;
• hanging heaters;

• Movement of dust in the room.

What makes the savings

In general, this type of heating cannot be called economical. But if the country house is used only for a couple of days during the winter, then this option will save significant funds for the organization of a full-fledged heating system. Due to the absence of liquid, a house with convectors can be safely left at sub-zero temperatures.

Oil appliances

Such heaters are sealed devices with a metal case in several sections. Mineral oil is used inside. With the help of a tubular electric heater, the oil heats up and warms up the body, and from it the air in the room. This type of heater is widely used.

Photo 4. oil heater. The device is on wheels and can be moved to different parts of the house.

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 more complex system heating.
• 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.

In the photo there is an electric convector from Nobo, Norway

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, so they are also called heaters and oil coolers. 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 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 work 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 have small 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. Such a panel can be used as an independent source of heating or as an addition to existing system. Matches well infrared heater With electrode boilers. For example, an infrared heater can only be turned on in spring and autumn, when it is still too early to turn on the main heating, or when it suddenly gets cold outside.

conclusions

1. 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.
2. If we compare bills for electricity, firewood, coal, pipes, boilers and other equipment, we can conclude that heating with private electricity is cheaper than stoves and other alternative heating gas systems.
3. 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 to see how it was done cheap heating electricity of a large private house.

In many countries, the main heating appliances are designed to consume electricity. In Russia, there is also a tendency to increase the share of installed electrical appliances in this area. In addition to the most famous water electric heater, various systems which are based on high-tech materials and processes.

When solving the dilemma, what is better gas or electric heating at home, the number of fans of the second option is growing. This is due, among other things, to the less bureaucratic red tape inherent in the installation of gas systems.

Advantages / disadvantages of electrical appliances

A wide range of electric heaters for the home allows you to identify most of them a lot of positive aspects. They relate both to the performance of heating from electricity, and to the installation qualities of electric heating in an apartment or house.

Among them are the following points:

• there is no need to accumulate large reserves of fuel, as is the case with solid fuel boilers;
• relative safety, since electric heaters do not have areas with open fire in their design;
• electric heating of an apartment is more environmentally friendly than other types of heaters, due to the absence of aggressive waste into the atmosphere, the minimum parameters in terms of sound characteristics, and the absence of any smell;
• electric heating at home it will not require additional space for equipment, it will easily fit in almost any kitchen, it will fit into the interior design;
• wide choose models will allow you to choose equipment suitable color, dimensions, power and installation methods;
• heating electrical appliances for the home operate offline without human intervention, if necessary, you can quickly configure / reconfigure any parameters, take preventive measures;
• electric heating systems have a lower price tag than gas units, as well as their installation is easier and simpler;
• dimensions and weight that electrical elements heating of a private house, small, which does not create an additional load on any building.

However, there are also negative aspects of electric heaters for the home:

• not everywhere there is a powerful electrical wiring that can withstand significant loads;
• electrical system heating increase energy consumption, which affects utility bills;
• if the electric heating of a private house is done by hand, as in the video, then you need to make sure that each electrical appliance is compatible with the domestic domestic network, and if necessary, a stabilizer or uninterruptible power supply is installed in the circuit.

Application of electric water heating

Electrically powered hot water heaters are generally found to be more efficient than systems operated solely by direct electrical heating. The heat carrier in water systems is heated to operating temperature water.

The heating of the liquid is carried out in the built-in boiler or boiler. An electric boiler for a water-heated floor must have high power characteristics in order to provide heat to a house or apartment.

During installation autonomous systems where the main role is played by an electric water heater, the following types of installations are used:

• induction;
• electrode;
• TENovye.

The last type is the most common. The principle of operation is that water enters the tank, heat is transferred to it from the heating element, and then it is forcibly distributed through the system using a water pump to the radiators. From them, the coolant returns to the boiler.

VIDEO: Overview of electric boilers

Warm floor

It is rare to find a water heated floor from an electric boiler as the main source of heating. More often it is used as additional system. The structure is mounted under the floor covering. In some areas, temperature sensors are installed to control heating.

Not in all cases, an electric boiler for a water-heated floor is in demand. Heating can be carried out with a special cable, inside of which there is a heating element. Its wiring diagrams can be both a snail and loops. On top of such heat mains, concrete screed. It ensures uniform distribution of heat.

Despite the complexity of the installation of cable underfloor heating, most of consumers prefer it. Such a system is considered more reliable than infrared floors or warm mats, although there are no objective assessments and expert opinions on this issue. On the contrary, at alternative systems more pluses - the final cost is lower, because there is no preparatory work for laying the screed, maintainability is high - there is no need to dismantle the floor, it is enough to replace the damaged unit, suitable for all types floor coverings etc.

The use of convectors and radiators of various types

For local heating, demanded units are oil-filled heating radiators powered by the mains. The body of such a device is structurally equipped with the largest possible surface due to the use of ribs. Electric heating elements are immersed in a mineral-type coolant. In most cases, their power is 2-3 kW.

Such devices are not among the most economical, and are not used for continuous operation. However, they effectively cope with their function within a small room.

The use of convectors, which are mounted in rooms where it is problematic to install water systems, is more justified. These heating electrical appliances for the home work according to the following principle. Built-in heater inside electrical energy into thermal. The heated air is redirected upwards through a special grille. Cooled air comes in naturally from below.

Each device has a temperature sensor that turns off the heating when enough heated air enters the lower intake hole. Customers often choose which electric convector is best based on output characteristics and power consumption.

To date, the range of such convectors is very large and on sale you can often find various design solutions in the form of pictures.

infrared devices

More modern type electric heaters for the home are emitters of the infrared spectrum. This electric heating system of a private house does not heat the air, but the objects inside the room. You need to understand that oil radiator you can design it yourself, but systems with infrared radiation will have to be bought.

This type of heating with electricity in a private house has one of the highest efficiency among electrical analogues. This makes it as efficient and economical as possible. However, at the stage of purchase, you will have to pay the high cost of such devices. The popularity of infrared heaters is associated with their ability to quickly and for a long time warm up the premises. The principle of operation corresponds sunbeams when it is not the air in the room that is heated, but solid objects, including people, interior elements, the floor and ceiling. Due a large number heat-releasing surfaces, the room heats up very quickly. The only disadvantage is the close range - the farther from the IR heater, the colder it is.

VIDEO: Economical electric heating of a private house - myth or reality

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 (permissible power limit) is not sufficient to connect several heating devices 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?

By years of experience we can say that the simplest and most inexpensive way to implement electric heating country house or dacha 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 benefits before other electrical 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 the cold. 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. Great 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 allocated to a house electric power 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 will knock out ( circuit breaker)…

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 switch 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.

First 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 only one of the 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 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 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 make the most economical electric heating in their house, but the power allocated to their house (permissible power limit) is not enough to connect several heaters 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 to use electric heaters convection type - convectors. They have proven themselves for heating 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, and absence drafts.

The heating elements of electric convectors have a low mass and thermal inertia, therefore warm up quickly. Unlike, say, radiators filled with oil. Therefore, the efficiency of such a heating device is very high, and 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 significant energy savings, because the heater does not work all the time, but only when the air temperature drops. Those. cyclically. The cycling of the heating on allows you to use new technology optimizing power consumption to get the most out of the network and not exceed the allowed power. This device will be discussed below (called OEL-820).

2. The best indicators for operational safety

Modern convectors contain heating elements that do not heat up above 100°C. At the same time, the temperature of the convector body remains below 60°C. Convector does not burn oxygen. Most devices of this type have increased moisture protection(IP24), so they can be safely installed in lavatories, 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

Electric heating convector ready to 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 a water heating system. Those. if we compare one-time investments for the purchase of electric convectors and for boilers operating on any type of fuel, including the most economical - main gas, then the difference will be enormous.

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, such as the OEL-820 Clusterwin grid load optimizer, which reduces the overall power consumption and allows you to operate them even with an insufficient limit of permitted power. This is very important for a country house. In addition, the load optimizer does not require installation, but simply plugs into the socket, like an adapter - an adapter. The electric boiler requires a large input power, which cannot be reduced.

7. Insensitivity to mains voltage fluctuations

Heating elements of convectors 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 in previous articles.

To connect energy-intensive electrical appliances, we will use three OEL-820 CLUSTERWIN load optimizers for the power grid.

Third floor. One large room is a 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 switch 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 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 will never exceed 1 kW.

First floor.

The kettle and water heater are also connected to the mains via the OEL-820. 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 only one of the 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 through three power grid load optimizers, the total power consumed from the power grid will never exceed 3 kW!

Which electric convectors to choose?

This is a matter of taste and wallet. It is clear that you should buy only devices from well-known manufacturers. This is your safety. In addition, the service life of the most inexpensive convectors usually does not exceed 5 years, and convectors, for example, from NOBO, will serve you for 30 years. As they say - feel the difference. And think about whether it's worth it. If for temporary heating, for a certain period, for example, gas has not yet been connected, then inexpensive ones will do. In other cases... think for yourself.

note 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.
