PURPOSE:To enable simultaneous operation of a bath boiler from the initial state of the starting of operation of a hot water feeder, by a method wherein the delivery port of the hot water feeder and the bath tub suction port of a forced circulation passage are positioned facing each other so that feed hot water from the hot water feeder is delivered in the form of jet streams to the bath tub suction port of the forced circulation passage. CONSTITUTION:A delivery port (c) of a hot water feed passage 3A for a bath and a suction port (d) of a circulation passage 8A on the suction side are positioned facing each other in a horizontal direction, extending at right angles with the hole axis of an upper hole (a), so that hot water delivered from a hot water feed passage 3A for a bath is delevered to a circulation passage 8A on the suction side at the interior of the upper hole (a) in association with the feed pressure of a hot water feeder 1 and the suction pressure of a circulating pump 9. When a bath tub 4 is filled with hot water having a proper temperature through operation of both the hot water feeder 1 and a bath boiler 7, hot water fed from the hot water feeder 1 is delivered, in the upper hole (a), to the circulation passage 8A on the suction side, and after the feed hot water is further heated by means of the bath boiler 7, it is delivered and fed to the bath tub 4 through a lower hole (b) by means of a circulation passage 8B on the delivery side,. This constitution enables simultaneous operation of the bath boiler 7 from the initial stage of the starting of the hot water feeder 1, and enables high-efficient filling of the bath tub with hot water having a proper temperature through operation of both the hot water feeder 1 and the bath boiler 7. |
