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 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:A burner 25 for an instantaneous water heater and a burner 26 for a bath heater are independently provided in a hot water supplying bath heating device 1. At the same time, the instantaneous water heater 2 and the bath heater 3 are disposed in an array with a partition plate 27 between them. 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, the hot water obtained at the instantaneous water heater 2 is sent to an outlet water boiler space 21 and further sent through a heat transfer pipe 20, an intermediate water boiler space 18, a rectangular pipe 17 and an inlet water boiler space 15 to a bath heater, resulting in improving the heating efficiency at the bath boiler. |
