Electric boilers are compact, are a wall structure and can eat from a 220 or 380 in network. When choosing any heating boiler, engineers use the formula for calculating thermal energy. 1 kW of heat is required for 10 m2 of heated area, provided that the average heat insulation, standard Belarusian winters and ceilings heights are not higher than 2.5 meters. Each case is individual and for heating 10 m2 may be needed more or less than 1 kW of thermal energy.
