PURPOSE:To eliminate an operating condition in respect to each of switches and to enable a simple use of an automatic hot water feeding device by a method wherein when only a follower switch is operated and hot water remains in a bath tub, an additional operation relating to a change of hot water is carried out and in turn when there is no hot water, the hot water is fed to a bath tub in response to a hot water feeding condition in place of a hot water feeding switch. CONSTITUTION:As operation switches, there are a full automatic switch 74 for performing an automatic hot water feeding, a hot water switch 75, a warm water switch 76 and a full switch 77. When each of the switches 75, 76 and 77 is singularly operated, if there is no hot water in the bath tub B, a similar action to that of the full automatic switch 74 is attained and then an instruction for performing an automatic hot water feeding corresponding to a set hot water temperature and a water level is given. If there is already hot water in the bath tub B, the hot water switch 75 gives an instruction of additional boiling, a bath burner 5 is operated only for 3 minutes, the warm switch 76 gives an instruction to lower a hot water temperature and then feeds water of 10l into the bath tub B. The full switch 77 may giver an instruction for increasing the water level and additional supplying of hot water of 20l is carried out. |
