PURPOSE:To buffer an actual water supplementing temperature properly, by a method wherein the supplementing of water is started by driving a circulating pump for the additional heating of a bath and switching the temperature conditioning setting of a hot-water supplier to a set bathtub temperature when the water level in a bathtub becomes lower than a given level while the supplementing of the hot-water is effected intermittently when the supplementing hot-water temperature is upper than a given temperature range. CONSTITUTION:When a switch for automatic water supplementing is thrown in a remote control panel 14, the water level of a bathtub 1 is monitored by a level detecting sensor 15 and when the level of the bathtub has become lower than a given value, and driving of a circulating pump 5 is started through a controller 13. The temperature conditioning setting of a hot-water supplier 7 is switched by the controller 13 from a set temperature, set for normal hot-water supplying, to a set bathtub temperature, setting the temperature of the bathtub 1, and the combustion of a burner 10 for a hot-water supplier 7 is started. A hot-water temperature from the hot-water supplier 7 or a supplementing hot-water temperature is detected by a supplying hot-water temperature detecting sensor 17. When the supplementing hot-water temperature T is within a given temperature range including the set bathtub temperature TS, a dropping control valve 9 is opened continuously through the controller 13. When the temperature T exceed said given temperature range, the dropping control valve 9 is opened intermittently through the controller 13. |
