The steam pipe 7 also serves as an overflow pipe in the hot water tank. With the above configuration,
The tap water supplied into the hot water tank 1 through the pipe 5 and the solenoid valve 6 is heated by the heater 2 and heated until it exceeds the set value of the temperature detector 3 of the hot water. The hot water held by heating is heated by a timer (not shown) to boil by operating the heater 2 at regular intervals, and continues to be heated until it exceeds the set value of the steam temperature detector 8 attached to the steam pipe 7. By the operation, the chlorine odor caused by the organic matter in tap water and the compound of chlorine for sterilization is removed by sufficient heating of the compound and the evaporation thereof. The hot water heated in this manner is supplied from the hot water tank 1 through a pipe line (not shown) in accordance with a tea supply request (not shown). When the water level of the hot water tank 1 reaches the set lower limit by repeating this hot water supply, the lower limit switch 42 of the float 4 is actuated to open the solenoid valve 6 and
The tap water is supplied to the hot water tank until the upper limit switch 41 of the float 4 operates.
