When the supplying of hot water to faucet and the injection of hot water into bath tub are conducted by the using of separate mixing valves, it is possible to supply hot water at stabilized temperature even when the injection of hot water into bath tub is conducted. When the start of the injection of hot water into bath tub is judged and the stop of the injection of hot water into bath tub is judged (steps 140, 150) during the hot water supply to faucet, the adjustment quantity of the valve-opening of the mixing valve for hot water supply to faucet is set up according to the bath tub set-up temperature and hot water injection set-up temperature (steps 148, 152, 164, 168), cooperating with the timing of the start of hot water injection or the stop of hot water injection, the valve-opening of the mixing valve for hot water supply being adjusted in the direction of suppressing the fluctuation of the temperature of hot water supply (steps 150, 154, 166, 170). Therefore, hot water supply at stabilized temperature to faucet can be conducted. |
