PURPOSE:To contrive to increase the hot water supplying capacity on a large scale by a method wherein the hot water, which is obtained by an instantaneous water heater and has constant temperature, is forcibly sent to the heat transfer pipe of a bath heater in order to pour the hot water in a bathtub while heating it again. CONSTITUTION:When a solenoid valve 13 is open under the state that no hot water is left in a bathtub and a hot tap 11 is closed, water flows through a feed water pipe 9, resulting in bringing the burner 25 of an instantaneous water heater to ignite. After the ignition of the burner 25, the water absorbs heat from heat absorbing fins 7. The resultant heated water is sent through a solenoid valve 13 arranged at the one tip of a hot water supplying pipe 10, a hot water pouring pipe 14, a funnel 24, a riser 23 and an outlet water boiler space 21 in the order named to a heat transfer pipe 20. In this case, because a burner 26 for a bath heater is ignited simultaneous with the opening of the solenoid valve 13, the water sent to the heat transfer pipe 20 is heated again at the heat transfer pipe 20 and poured through an intermediate water boiler space 18, a rectangular pipe 17, an inlet water boiler space 16 and a circulating inlet pipe 15 to a bathtub, resulting in supplying the water with proper temperature into the bathtub. |
