<p>PROBLEM TO BE SOLVED: To facilitate storage of hot water, heated to a desired temperature, while thermal stratification is prevented from being disturbed due to hot water flowing in a hot water storage tank. SOLUTION: A hot water type hot water supply heat source device comprises a hot water storage tank 1, to which a hot water supply passage 6 is connected; and a hot water circulating means for circulating hot water in a hot water storage operation state under a state where hot water flows in the hot water storage tank through a hot water inlet 101 formed in the upper part of the hot water storage tank after hot water taken out from the bottom of the hot water storage tank is heated by a heating means. A hot water catch body 106 is situated in a state to be positioned opposite to the hot water inlet at the inner upper part of the hot water storage tank and at a position below the hot water inlet. The hot water catch body is provided with a lateral passage part 113, to cause its passage in the lateral direction of hot water, flowing in through the hot water inlet, and a downward passage part 114 to cause the passage of hot water, flowing in through the hot water inlet, in the downward direction.</p> |
