Then, heat is exchanged with water for hot water supply at the outlet side heat exchange section of the heat absorber in the upper part of the heat storage tank. Therefore, even when the temperature inside the heat storage tank body is low, hot water can be quickly supplied. In addition, when the heat medium temperature in the upper part of the heat storage tank body rises, heat exchange is actively performed in the lower part of the heat storage tank by the outlet side heat exchange parts of the heat exchanger for heating the tank and the heat exchanger for heating the auxiliary tank. It becomes like this. Therefore, the entire M heat tank body can be heated efficiently, and a large actual heat storage capacity can be obtained.
