STORAGE TYPE HOT WATER SUPPLY DEVICE

摘要

PURPOSE: A hot water storage type hot water supply device is provided to rapidly supply hot water in a target hot water temperature from a tapping pipe by operating auxiliary heat source units although hot water is used up in a hot water tank in heating prohibition time. CONSTITUTION: A hot water storage type hot water supply device (1) comprises a hot water storage tank (11), a water supply pipe (12), a tank heating unit, an auxiliary heat source unit, a heating prohibition time setting unit (123), a tank heating control unit (124). The auxiliary heat source unit heats hot water to a target hot water temperature when the temperature of hot water flowing in a tapping pipe is lower than the predetermined target hot water temperature. The heating prohibition time setting unit prohibits the operation of the tank heating unit and sets the heating prohibition time during daytime according to predetermined conditions for increasing electricity consumption by a power conditioner. The tank heating control unit prohibits the operation of the tank heating unit in the heating prohibition time setting unit.
