PURPOSE:To improve the thermal conductivity of a heat exchanger, enable to miniaturize the titled device and reduce the radiation loss thereof by a method wherein a heat exchanger arranged in a hot-water tank is made as a double pipe structure, a hot-water in the hot-water tank is circulated through an inner pipe of the heat exchanger. CONSTITUTION:A heat exchanger 14 having a double pipe structure is arranged in a hot-water tank 3. By driving a circulating pump 7, a hot-water 17 is raised in temperature by the condensing heat of a refrigerant 15 flowing through an inner pipe 18 of the heat exchanger 14. The heat exchanged hot-water 17 is introduced into a circulating pump 7 via a outlet pipe 24, then discharged via an upper part 19 in the hot-water tank 3 or via a discharging piping 25 as shown by an arrow mark B. By protruding an upper header 20 of the heat exchanger 14 to the outside of the hot-water tank 3, the number of piping penetrating holes arranged on the hot-water tank 3 can be decreased.
