Electric boilers for heating a private house convert electricity into thermal power, promote the circulation of coolant in the pipes. These heating units are highly efficient. They can be used as an auxiliary heat source for main gas heating. An electric heating boiler is an alternative to heating a home in cases where a standard gas system is not possible.
The operation of these boilers has its advantages over gas analogues, solid fuel heating systems:
- affordable push-button control system;
- acceptable price;
- low fire hazard;
- complex automation;
- environmental friendliness;
- accessibility of installation in rooms of any sizes;
- no need to bring additional pipes to the house;
- compact dimensions with high power.
Types of electric boilers for heating a private house
When choosing a boiler, it is necessary to take into account all parameters, individual heating requirements of your home. In this case, you should not rely on the appearance of the device, but look at its internal functions.
Electric boilers for heating a private house are divided into single-circuit and double-circuit. Single-circuit only work for home heating. If, along with room heating, you want to have hot water, then choose a dual-circuit model.
These boilers come with single-phase and three-phase connections (220 V and 380 V). There are low-power (up to 12 kW) electric boilers of both types, but if you need a large, powerful unit, then it will be only three-phase. Be sure to pay attention to the features of the electrical network in your area of residence. It is recommended to stipulate the choice of the boiler in advance, the rest of the installation nuances with professional electricians.
It is better to choose heating or electrode electric boilers.
Electrode work on the principle of passing an alternating electric current through heated water. Such units are convenient in that they can automatically turn off when short circuits or overheating.
TENA analogues, in fact, are ordinary heaters - they work on the principle of a simple boiler. Such boilers are very reliable, most often purchased by customers for heating purposes.
Electric boilers are wall and floor, the first option is more popular, as it saves space in the room. Wall-mounted models are a priority of foreign manufacturers, in turn, floor-mounted boilers are most often of domestic origin.
Floor heaters are also used for large heating systems.
Electric boiler for home heating - reviews
Against the background of the positive characteristics and advantages of electric boilers, it will be fair to point out some negative points. For example, electrode boilers require periodic replacement of the electrodes - from the movement of ions during operation, the coolant overheats.
Heating elements, in turn, are also subject to cleaning or replacement from time to time - because of the settling salts, heat exchange is disturbed, and efficiency is reduced.
When you consider models, choose an electric boiler for heating a private house, customer reviews and opinions will come down to one factor - high electricity prices. It follows from this that, to provide heat to very large areas, such units will, alas, be unprofitable.
Here are some reviews:
I have the fourth winter working electrode GALAN. While the flight is normal. I use it at night to maintain a comfortable temperature, as well as when I'm leaving for a few days. Basic heating with wood. A 9 kW boiler easily heats my 95 squares.

From personal experience, the House of permanent residence (100 sq m + socle 100 sq m) near Vyborg, well insulated. I have been heating it with electricity for 12 years (convector 800 W -2 pcs, oil cooler 500 W, warm floor 500 W). For the soul and in especially windy weather I drown the fireplace. I go to the house barefoot all year. The neighbor has exactly such a house has a 9 kW electric boiler. The first years when paying for electricity came to a fight :)] ... I pay in the winter of 1000-1500 rubles, it is 5000-8000 rubles. They came and looked and went to warm up and "screw" the boilers ...

For a long time I wondered which electric boiler is better for a private house of 45 square meters. m. The criteria were as follows - affordable price, extreme simplicity, reliability. As a result, he stopped on technology from EVRAZ. I chose a 6 kW model so that there was a small margin. The electric boiler can operate from a single-phase or three-phase network and heat the area up to 54 square meters. During operation, the entire bottom was found to be broken - one of the heating elements burned out, repairs were carried out under warranty. Heats well and silently, does not require maintenance. I consider heating with an electric boiler in a private house the best option, since there is no need to bother with diesel fuel or firewood.

Galan needs a special coolant, and induction electric boilers give little gain in efficiency. Estimate first the total heat loss of your home. Offhand, it seems, at least 100 watts per meter of heated area. This means that the boiler is needed with a capacity of at least 5 kW. Somewhere around 7-8, I suppose, should be enough. It is possible on a single phase. Almost any boiler will do. I like something like Saviter. Inexpensive, without unnecessary frills, but has everything you need and is made soundly.

Technical characteristics of the electric boiler: what to look for
The technical characteristics of the boiler determine the type of power adjustment - it can be smooth, stepwise or even absent. An electric heater may have several separate heating elements. Turning them on or off affects the increase / decrease in water temperature, as well as the level of electricity consumption. Individual, more precise settings (for example, the temperature in different rooms) are made using a thermostat and valves (gates).
Stepless control makes it possible to set more precise power parameters. An electric boiler with this function is more economical. The presence of a rheostat is a feature of such models.
Separately, it is worth mentioning economical electric boilers with intelligent control. An energy-saving electric heating boiler works “on demand”, it generates as much heat as a single room needs. These units have controlled thermal inertia, and their efficiency is almost 100%. Quick heating of the coolant (water), the absence of sound vibration during operation are the advantages of heaters of this type.
The simplest boilers do not have an adjustment function, they are low-power, can be used to heat small cottages.
A complete set of electric boiler has all the necessary accessories. This is the case when buying a cheaper model can be more expensive, subject to the subsequent selection of missing parts. If we take into account the cost of installing the unit, then the option of acquiring everything immediately becomes more profitable. For the full-fledged operation of the system, it is necessary to have water purification filters, safety valves, an expansion tank, and a circulation pump.
An electric heating boiler with a pump (circulation pump) can be either a heating element or an electrode type. The pump is almost the main element of the entire system - it provides continuous movement of water through the pipeline. Thus, a stable heat transfer mode is maintained, and the entire area of the house is evenly heated.
In general, electric boilers are the best modern choice for home heating. Individual models can be programmed for several days in advance, they are not afraid to leave unattended for a long time. Installation of such heating systems does not require a permit; they do not pollute the environment during operation.
Electric boilers for heating a private house will provide you with comfort and warmth with relatively low material costs. Compared to gas or solid fuel, electricity holds the position of the most profitable energy resource today.
