PURPOSE:To obtain hot water at arbitrary temperature and of an arbitrary amount through a hot water feed faucet without being affected by operation of other hot water feed faucet when opening some faucet of a plural number of hot water feed faucets being differenr in a using hot water temperature and a necessary hot water quantity. CONSTITUTION:In case hot water is obtained through a hot water feed faucet (a), when hot water temperature is set by a remote control part at that place, a valve E, simultaneously, is closed and a valve F is opened, and then, the hot water feed faucet (a) is opened. This causes producing of a water current in a water feed pipe 11, a branch water pipe 17, and a hot water pipe 17, and with a flow water switch 12 activated, a self-gas valve 14 opens, gas is fed to a burner 3 to start a burning. With only a after heater A actuates, hot water, corresponding to the capacity of the heater A, is obtained through the hot water feed faucet (a). In case hot water is obtained through a hot water feed faucet (b), a desired hot water is fed through the hot water feed faucet (b) through operation of only water heater B. In case a large amount of hot water is obtained through the hot water feed faucet (a), a desired hot water temperature is set by an remote control part at that spot, and simultaneously, valves E and F are opened, a value G is closed, and the hot water feed faucet (a) is opened. This causes actuating of water heaters A and B obtains hot water being fed corresponding to the summed up capacity of the two heaters. |
