<p>PROBLEM TO BE SOLVED: To provide a hot water storage type hot water supply heat source device capable of respectively efficiently storing hot water in a hot water storage tank and radiating heat in an external heat radiating part. SOLUTION: A hot water storage type hot water supply heat source device is provided with hot water circulating means J for circulating hot water in a hot water storing and circulating state so as to store hot water in a hot water storage tank 1 with an upper part connected to a hot water supply passage 6 by forming a thermal stratification. The hot water circulating means J is freely switched to a mode for branching and supplying all or a part of hot water heated by heating means K to external heat radiating parts H and to an external heat radiation circulating state that all the amount of hot water from the external heat radiating parts H bypasses the hot water storage tank 1 and directly returns to the heating means K. A control means S switches the hot water circulating means J to a hot water storing and circulating state to obtain a hot water storing state and switches the hot water circulating means J to an external heat radiating circulating state to obtain a heat radiating state to execute the control of an operation.</p> |
