<p><P>PROBLEM TO BE SOLVED: To provide a storage type hot water supply system capable of preventing the shortage of hot water while supplying the amount of hot water required by a user. <P>SOLUTION: The storage type hot water supply system 10 includes: a hot water storage tank 14; a heat source machine 70; a circulation route 76 circulating hot water between the hot water storage tank 14 and heat source machine 70; a water supply route 24 supplying water to the hot water storage tank 14; a hot water supply route 46 supplying hot water from the hot water storage tank 14; and a control means 146 controlling a heating amount by the heat source machine 70. The control means 146 executes: a procedure of restricting the heating amount to satisfy restriction to prevent a water temperature after passage through the heat source machine from exceeding an allowable temperature; and when heat quantity made to flow out of the hot water storage tank 14 becomes larger than heat quantity made to flow in to the hot water storage tank if the heating amount is restricted in the procedure of at least either of a procedure of increasing the allowable temperature and a procedure of increasing the amount of hot water circulated in the circulation route 76. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
