<p>PURPOSE:To output hot.water of a desired set temperature even when general- purpose hot water supply and bath hot water supply are simultaneously conducted. CONSTITUTION:An input water branch circuit 5 is provided, a hot water/water selecting valve 44 is provided at a connecting position of a hot water supplying circuit 4 of the circuit 5. At the time of simultaneously using general-purpose hot water supply and bath hot water supply, hot water heated by a heat exchanger 10 of a hot water supplying circuit 2 is branched to a faucet 8 and a bathtub 28 to be supplied when set temperatures of both the hot water supplies coincide, while the hot water heated by the exchanger 10 of the circuit 2 is supplied to the faucet 8 when both the set temperatures are different. On the other hand, water before it is heated by the exchanger 10 is supplied to a bath circulating circuit 3 via the circuit 4 from the circuit 5 as it is, and the input water is heated by a heat exchanger 32 of the circuit 3 and supplied to the bathtub 28.</p> |
