| 摘要 | PURPOSE:To supply hot water from the begining when hot water is to be discharged out of a hot water supply pipe by causing the thermal medium having been heated in a heat exchanging part to exchange heat with the hot water inside the hot water supply pipe by its natural circulation inside the heating pipe of a closed circuit. CONSTITUTION:When the water inside a heat exchanger 2 is heated by igniting a burner 1 and blowing the burning hot stream onto the inner surface of the heat exchanger 2, the heated water is led out of the heat exchanger 2 through a hot water supply pipe 4, and can be discharged out of a tap 17. The burning hot stream from the burner 1 is also blown to the heating part 5 of a heating pipe 7. The heated thermal medium in the heating part 5 rises in the heating pipe 7 to enter into a heat exchanging part 6 where it exchanges heat with the hot water in the hot water supply pipe 4 to heat the hot water, and thereafter returns to the heat exchanging part 6 by the natural circulation. Therefore, the hot water in the hot water supply pipe 4 is always heated by the thermal medium, and does hot cool off in the hot water supply pipe 4 by releasing heat. | ||||||
