Choosing a boiler: assessing the main parameters
When purchasing a heating unit for furnishing electric heating systems It is worth taking into account the area of housing, the heat-saving indicators of the materials from which the house is built, as well as the climatic characteristics of the region.
Basic selection options:
- power;
- connection type;
- equipment;
- performance adjustment method;
- control option.
Power. The main characteristic showing the heating intensity. To determine it, use special calculators, rely on the recommendations of boiler manufacturers, or calculate it yourself.
To the resulting value add 100 W per window and 200 W per entrance door.
The climate zone should also be taken into account. Table coefficients by which you need to multiply the calculated figure:
- northern regions – 1.8-2;
- central zone – 1.2-1.4;
- southern area - 0.7-0.9.
When choosing an electric boiler for a cottage or private house, the final value should be multiplied by 1.5. A reserve of 50% is needed to cover heat costs through the ceiling and walls.
This parameter depends on the boiler power. For devices up to 9 kW it is possible to connect to a single-phase network. High-power units require a 380 V network supply. A separate three-phase network will require permission.
Equipment. There are two options:
- basic equipment - purchase of one boiler, the remaining necessary components will have to be purchased separately;
- mini-boiler - a complete boiler.
The second option is preferable. Purchasing and installing all components separately will cost more than purchasing and commissioning a complete boiler.
Power control method. The ease of use of the device depends on this parameter. Stepwise and smooth adjustment is possible. The first option is used in boilers with several heating elements.
Smooth power selection is preferable. Its advantages: obtaining a more comfortable microclimate, energy efficiency. In budget versions of low-power boilers, there may be no performance adjustment at all.
Control methods:
- Mechanical. Such boilers are affordable, but the accuracy of temperature control is insufficient. In addition, mechanical systems are loud - clicking sounds are heard when shifting. This option is suitable for boilers operated in non-residential premises.
- Electronic. The control system is more convenient and economical. The use of electronic thermostats and thermostats allows you to save up to 20% of electricity. The downside is the high cost.
It is worth paying attention to the features of the case. It is better to choose a closed type boiler so that children do not have access to electrical parts.

Conclusions and useful video on the topic
Comparison of Protherm and Stout boilers:
When choosing an electric boiler, you should pay attention to the brand name. It is better to give preference to reputable companies whose quality of products is confirmed by positive user reviews and relevant certificates. It is better to refuse unknown brands, because not only comfort, but also safety of use is at stake.
Perhaps you managed to purchase a new model of electric boiler? Please tell us which device you preferred, what guided your decision, and are you satisfied with the performance of the equipment? Leave your comments and ask questions in the block below.
I can’t imagine living in a house without individual heating and an electric boiler, which provides home comfort and coziness. We have a Habitat brand boiler. During operation, I can say that it has more disadvantages than advantages, or maybe we were just unlucky. At first it was serviced by the company from which it was purchased. The service is supposedly free, but you have to pay for them to come. It broke down every year, repairs cost money. It also did not tolerate power surges well, so I had to buy an uninterruptible power supply for it.
Yes, the comfort and coziness you describe is quite dubious. If you had so many problems with your boiler, then what comfort is there? I definitely wouldn’t have the nerve to repair it every year. Although, I can’t say anything bad about the Habitat brand. I had quite a long experience of using a boiler from this Italian company. True, in my case the boiler was gas, but still. He served his term to the fullest and without any serious complaints.As for “didn’t tolerate power surges well,” that’s already nit-picking. Which electric boiler will handle them well?
Hello. Actually, it's a strange story. Electric boilers usually have a wide range of exposure times. Anyway.
I have a question for you, what model is your boiler and its manufacturer, is it Hermann by any chance? I just know only Habitat boilers from this company and they are all gas.
I installed an electric boiler in my house in the village, since there is no gas, and heating with wood or coal is troublesome. It’s a great thing, I turned it on and there were no problems, it’s warm in the house, and safety is everything. The only downside is the electricity bill. When I was choosing a model, I chose the German brand “Vaillant”, it’s a little expensive, but it’s worth it. The boiler is easy to operate, like an Archimedes screw, but reliable, and copes with its task with a bang. Great thing if you don't have gas.
Why are only electric heating elements included in the review? Aren't there other types of electric boilers on the market?
Hello Alexey, can I ask you a question about the ind. boiler?
