Rating of the most economical and reliable electric heating boilers for a private home. Models are presented with durable heating elements, properly functioning safety automation and effective temperature control. Such boilers do not require complicated installation. There is no need to install a chimney, supply and exhaust ventilation or allocate a room for them. Modern models of heating element modifications have a built-in security system and other necessary elements and components, so to create a simple heating system you do not need bulky boiler piping. Below we will consider the methodology for calculating boiler power by area of the house, calculate energy consumption indicators in seasonal terms and give several ways to save energy.
To choose an electric heating boiler, you need to select the correct power and inspect the electrical wiring. The cross-section of the power cable must correspond to the load. Models up to 3.5 kW are connected directly to the apartment outlet. More powerful electric heating boilers operate through automatic protection devices, which are responsible for controlling the current strength.
The installation of electric boilers with a power of up to 10 kW does not need to be coordinated with Energonadzor. This is done only when connecting a multi-tariff meter in order to save electricity on the price difference between the day and night tariffs. For boilers with a power of more than 6 kW, it is necessary to organize a three-phase connection (380 V).
Boilers for houses up to 60 sq. m.

Advantages and disadvantages
The first question that worries any buyer is why should you consider this option? Is it better than other heating boilers?
Electric heating boiler - assembled system with external pumps
pros
Electric boilers:
- compact, light weight;
- easy to install, easy to connect and use;
- attractive in appearance;
- no need to make a chimney;
- work silently;
- cost less than gas, diesel and solid fuel boilers (from 9,000 rubles for a low-power device);
- safe, no open flame, switches off automatically in case of failure (for example, no water);
- can work without human supervision;
- can be used as a backup heat source;
- have high efficiency;
- do not require storing fuel;
- will last a long time;
- wide choice of models (for example, power - from 2 to 500 kW).
A misconception is that antifreeze cannot be used with electric boilers. This is quite possible in models where thermo-chemical gaskets are used for the brass nut (into which the heating elements are soldered).
Minuses
To objectively evaluate the option, you need to weigh the problems that may arise with the electric boiler:
Expensive kilowatt-hour. Only wealthy people can afford to completely heat themselves with electricity. In fact, it turns out that a season on electricity can be 2 times more expensive, compared, for example, with solid fuel.
The fact that this type of heating makes the house dependent on the supply of electricity is also not attractive. Sometimes I turn off the lights as planned, and accidents occur on the line. Wires are rarely stolen, but still. Being left without heating in the middle of winter, even for a day, is extreme.
Heating with electric boiler
Other difficulties:
- Networks do not provide sufficient power everywhere;
- Water circulation should be at level. If it is insufficient, the boiler may boil or shut down.
Considering the above, the use of electric boilers is advisable:
- In apartments where there are problems with heat supply, as auxiliary heating;
- in small well-insulated houses, especially if the owners periodically leave the house;
- in areas with mild climates, as the simplest way to organize heating;
- complete with a heat accumulator, if electricity costs less at night.

How to calculate the required power of an electric boiler?
Before determining how to choose an electric boiler for heating, find out how well the work has been done to preserve heat in your home. To do this, carry out the following test: on a winter day, measure the air temperature in each room on the floor and under the ceiling. The doors in the rooms must be closed for at least an hour so that a stationary state of warm air is established. The difference should be 2–4 degrees. If the difference is greater, you need to check all seals on windows, vents, balcony and entrance doors. If, after putting them in order, the situation does not return to normal, you need to insulate the windows, doors, walls, ceiling and even the floor.
If the insulation of the rooms is done correctly, then the choice of an electric boiler for heating can be made based on the required power for the entire house. It is calculated based on the condition of the presence of 80–100 W per 1 m2 . But this ratio does not take into account the climate in your area, your preferences - for example, washing your hands and washing your face with warm water or having a hot bath every day. In addition, the boiler power and electricity costs are greatly influenced by how the heating system is built .
If a night tariff and heat and hot water storage are used, the required power can be reduced.
Boilers for a dacha, a private house, an apartment, a country three-story mansion.
The choice of electric boiler is primarily influenced by the degree of autonomy . If it ensures the operation of a heating and hot water supply system for a large house , then it is better to choose an induction boiler of appropriate power.
If the house is small , it is not difficult to prepare or buy liquid or solid fuel, or install gas, then it is best electric boiler (TEN or electrode), connect it in parallel to the main boiler and use it in case of interruptions in the gas supply or in severe frosts as an additional source heat.
In some areas of the country, the use of electric boilers is very problematic, primarily due to voltage fluctuations, surges and dips or frequent and long outages. This problem can be solved by using electric generators with internal combustion engines and partially by using voltage stabilizers.
