ABSTRACT:
An object is to provide a heating tank capable of highly efficiently heating a target to be heated and having high safety and reliability, and a hot water storage tank. The heating tank in which the target to be heated is stored and which heats the target to be heated by a circulated refrigerant of a heat pump, for example, the hot water storage tank which is heated by the circulated refrigerant of the heat pump to produce hot water in the tank includes a heat exchanger in which a wall surface of a tank main body is partially secured to peripheral edge portions and inner portions of two metal plates and in which non-secured portions swell to constitute a refrigerant passage closed except an inlet and an outlet. A thickness dimension of one metal plate is set to be larger than that of the other metal plate, and the one metal plate is arranged on the inner side of the other metal plate.
