When the temperature of the mixed hot water starts rising, the valve 25 is opened at full speed at the water side to secure a normal temperature control state. In case the switch 30 is set at the side of an instant water heater, the hot water temperature has a gentle rising slope against the dead water/semi- dead water state. Then the valve 25 is kept in a state where its hot water side kept full open until the temperature of the mixed hot water rises up. When the temperature of the mixed hot water starts rising, the water side is opened. Then a normal temperature control state is set.
