<p><P>PROBLEM TO BE SOLVED: To provide a heat source device capable of stabilizing the temperature of hot water supplied from a hot water storage tank thermally connected to a heat collector and efficiently operating the heat collector. <P>SOLUTION: A middle part of a liquid circulation passage 3 for causing liquid to flow through the heat collector 1 which collects heat of solar light is caused to pass through the lower side in the hot water storage tank 2 and is made to be a passage path 11 in the hot water storage tank 2, and a liquid-liquid heat exchanger is formed with the passage path 11 in the hot water storage tank 2 and the hot water storage tank 2, wherein the liquid circulator passage 3 and the hot water storage tank 2 are thermally connected. A hot water supply path 12 and a water supply path 13 are connected with the hot water storage tank 2. A hot water circulation path 7 which is connected with a bath tank 27 and is provided with a bath tank hot water circulation pump 8 for circulating the bath tank hot water is thermally connected to the upstream side or the downstream side of the passage path 11 in the hot water storage tank in a liquid circulation passage 3, when satisfying predetermined collected heat using bath tank hot water heating conditions, a liquid circulation pump 4 and the bath tank hot water circulation pump 8 are driven, thermal exchange between the liquid passing in the liquid circulation passage 3 and the bath tank hot water passing in the hot water circulation path 7 is performed and bath tank hot water is heated by the heat collected by the heat collector 1. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
