3. power;
4. power supply (220 V or 380 V);
5. control system;
6. sizes;
7. the presence of a circulation pump;
8. appearance.

Separately, the protective devices are checked to prevent damage to equipment in the event of an emergency.

Which electric boiler is better to choose

The main criterion is power. For an approximate calculation, a typical formula is used: 1 kW per 10 square meters. area with a ceiling height of no more than three meters. It is recommended to make a reserve (15-20%) to ensure sufficient heating when the air temperature drops significantly. This solution will prevent undue stress on the equipment.
Mechanical control is cheaper. However, the electronics regulate the operating modes more precisely. This example demonstrates the benefits of complex analysis. The comparatively large investment in the purchase of a well-equipped model is offset by savings in the operation.

To determine which electric boiler is better, you need to take into account additional individual requirements:

1. when placed in a conspicuous place, the appearance of the equipment is essential;
2. for installation in a limited space of cabinet furniture, dimensions are the determining parameters;
3. in some situations, you will have to pay attention to the noise level.
