PURPOSE:To enable a hot water temperature to be decreased to a mild hot water temperature with a simple operation without changing a set temperature by a method wherein if a mild hot water switch is in its operating condition, water is supplied from a hot water feeder device to a bath tub and the water supplying operation is stopped when an amount of ed water reaches a predetermined amount or a mild hot water switch is not in its operating state and then operation of a forced circulating heater device is stopped. CONSTITUTION:A mild hot water operating member 52 is operated to cause a mild hot water switch to be operated, a control device 50 feeds water to a bath tub 10 from a hot water feeding device 30 through a forced circulation heating device 20 without operating a gas burner 37 and then a hot water temperature in the bath tub 10 is made low. Since this water feeding is automatically stopped if its volume reaches a predetermined amount, too low temperature of water may not be attained and if the mild hot water switch is not operated by operating a mild hot water operating member 52 during feeding of water, the water supplying is stopped. After stopping this feeding of water, the control device 50 may stop the operation of the forced circulation heating device 20. |
