Electric heaters of НП type (hereinafter НП) are designed to heat air entering the water tank. When pumping water from the tank in the cold season, cold air enters the tank, and can cause water freezing. To prevent this phenomenon it is necessary to heat the incoming air to positive temperature. To do this, an air heater is installed in the ventilation pipe of the tank.
