초록

A hot water storage tank (3) and a circulating path (12) coupled to the hot water storage tank (3) are provided. An operation is possible wherein low-temperature water, let out from a lower part of the hot water storage tank (3) and entering the circulating path (12), is heated and boiled up by a heat pump heating source for forwarding to an upper part of the hot water storage tank (3). A refrigerant circulating circuit of the heat pump heating source is provided with a defrost circuit (38) for supplying hot gas from a compressor (25) to an air heat exch...
