Abstract:
PROBLEM TO BE SOLVED: To provide a hot water supply system capable of properly determining whether or not sterilizing treatment of water in a tank is needed, in recovering from power failure.SOLUTION: A hot water supply system includes a tank, a heat pump for boiling up water in the tank, a tank thermistor detecting a temperature of the water in the tank, an outside air temperature thermistor detecting an outside air temperature, and a controller. In the hot water supply system, the controller drives the heat pump to boil up the water in the tank to a sterilizable temperature when the temperature of the water in the tank is lower than a reference temperature in recovering from power failure. The lower the outside air temperature is, the lower the reference temperature is set by the controller in the hot water supply system.
