The issue of heating is especially acute in a country house located far from city communications. When it is not possible to use gas as a fuel, one has to look for other economical options. In our opinion, the best way out of the situation is to install an electric boiler. But how to choose the right one? Let’s try to figure it out.
Overview of benefits
Firstly, the price for an electric boiler for heating a house is more than affordable. It is compact, simple and easy to operate. The principle of operation of an electric boiler is as follows: the device is powered by the mains, converting electricity into thermal energy. In simple words, heating elements give heat to the coolant, which, in turn, heats the air in the heated room through pipes and radiators. One or more heating elements are most often used as a heating element, but there are also boilers with an induction or electrode operation system.
- affordable price (compared to gas and solid fuel counterparts);
- convenience (you can connect in any room where there is access to the mains);
- intuitive control;
- safety (due to the absence of open fire and the need to add / check fuel);
- environmental friendliness;
- quiet operation (especially important in small houses);
- high efficiency.
What to look for when buying
The simplest option is single-circuit electric boilers. They work only for heating, so they are cheaper. If you additionally want to heat water with an electric boiler, then take a look at the double-circuit models. To connect to the shield, it is better to take a copper stranded wire, since with high current conductivity it will heat up less.
Before buying a boiler, we recommend that you calculate its efficiency in advance. A simple rule: put in 1 kW of power for every 10 m2. Of course, a lot here depends on the quality of the thermal insulation of the house, the height of the ceilings, the number of rooms and other factors. For a more accurate calculation of the required power of an electric boiler, you can use the formula W \u003d (40 * S * h + Qo + Qd) * k (its decoding is easy to find on the Internet). Among the most popular manufacturers of electric boilers, we can distinguish the following brands: Baxi, Protherm, Navien, Buderus, Viessmann, Vaillant, Bosch, Kospel, Ferroli, ZOTA.
