Abstract (en)
An object of the invention is, for example, to provide a hot water supply device capable of using the heat energy remained in the warm water used for the predetermined application such as the remaining hot water of a bath tub for heating the water by a simple structure. The hot water supply device of the present invention allows the heat energy of the remaining hot water in the bath tub to be recovered by the water flowing out from the lower part of the hot water storage tank heated by a gas cooler. Hence, it is unnecessary to recover the heat energy of the remaining hot water in the bath tub by a refrigerant circulating in a refrigerant circuit of a heat pump unit, and by a simple structure of only piping for water circulation, the heat energy of the remaining hot water of the bath tub is used in heating the water.
