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.
Benefits at a glance
First, the electric boiler for home heating price 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 from the mains, converting electricity into thermal energy. In simple words, heating elements provide 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 system of operation.
Pros:
- affordable price (in comparison with gas and solid fuel analogues);
- convenience (you can connect in any room where there is access to the mains);
- intuitive control;
- safety (due to the lack 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 only work for heating, so they are cheaper. If you additionally want to heat water using an electric boiler, then take a look at the two-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 purchasing a boiler, we recommend calculating its efficiency in advance. A simple rule of thumb: set a power of 1 kW for every 10 m2. Of course, a lot here depends on the quality of the house's thermal insulation, 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 = (40 * S * h + Qо + Qд) * k (its decoding is easy to find on the Internet). Among the most popular manufacturers of electric boilers, we can highlight the following brands: Baxi, Protherm, Navien, Buderus, Viessmann, Vaillant, Bosch, Kospel, Ferroli, ZOTA.
