Abstract

A hot water supply apparatus includes a heating heat-exchanger (31) a water passage of which is connected to the hot water storage tank (21) through a pipe line (P17) in which a pump (32) is interposed and a heating water passage of which is connected to a hot water heating system through a pipe line (P18) in which a pump (33) is interposed; a heat releasing heat-exchanger (35) capable of carrying out heat exchange with the evaporator (14) of the heat pump (HP) ; and a flow path changeover circuit (34, P20, P21) for sending heat-exchanged water sent out of the water passage of the heating heat-exchanger (31) to the heat releasing heat-exchanger (35) during the time when the heat pump is operated and the heating operation is also performed, or during the time when the defrosting operation is performed and the heating operation is also performed.
