PURPOSE:To reduce the change of a heat exchanger into abnormal pressure due to the further rise of the temperature of hot water, which temperature previously rises to fixed temperature due to the thermal effect of a bath furnace in the case when using a water heater, in the heat exchanger utilized for a compound combustor building in the water heater, the bath furnace, etc. CONSTITUTION:A compound combustor builds in a bath furnace consisting of an exhaust cylinder 3, a heat exchanger 4 and a burner 5 for a bath and an instantaneous water heater being composed of a heat exchanger 6 and a burner 7 for hot-water supply in an appliance case 2 provided with an exhaust port 1 for common use. In this case, said heat exchanger 6 is formed by a fin portion 9 equipped with a heat exchanging pipe 8 and a cylindrical drum portion 10, to which upper portion the fin portion 9 is mounted. The heat exchanging pipe 8 is connected to a hot-water supply stopcock 11 while using a terminal of the drum portion 10 as an outlet 8a, and connected to a hydraulic pressure responding device 12 while utilizing a beginning end at the fin portion 9 side as an inlet 8b. Since above-mentioned constitution can prevent the change of the heat exchanger 6 into abnormal pressure, hot water can stably be supplied. |
