<p><P>PROBLEM TO BE SOLVED: To provide a hot water supply heat source system capable of allowing a user to sanitarily use the hot water supplied using a hot water storage tank of a cogeneration hot water supply heat source device as a heat source. <P>SOLUTION: In the hot water supply heat source system comprising the cogeneration hot water supply heat source device for supplying the hot water stored in the hot water storage tank to a hot water supply destination by utilizing the exhaust heat of a generator 1, a drainage water solenoid valve 52 and a drainage water passage are formed at a lower side of the hot water storage tank. A hot water storage tank hot water staying state detecting part 37 determines a value of a staying time of the hot water in the hot water storage tank on the basis of the monitor information relating to the detection of the hot water storage tank hot water staying state of the cogeneration hot water supply heat source device, and an automatic drainage executing part 40 opens the drainage water solenoid valve 52 and automatically drains the hot water in the hot water storage tank from the drainage water passage, when the value of the staying time of the hot water in the hot water storage tank determined by the hot water storage tank hot water staying state detecting part 37, becomes more than a set value of the predetermined drainage time. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
