| 摘要 | PURPOSE:To make the titled hot water feeder compact and small-sized and to improve the combustibility thereof by a method wherein exhaust gas passages which are independent of each other are provided. CONSTITUTION:Two kinds of combustion burners 19 and 20, combustion chambers 21 and 22 and heat exchangers 23 and 24 are provided in the body 18 of the hot water feeder. One of the heat exchangers 23 is in communication with an exhaust cylinder 25 whose top end confronts an exhaust top chamber 27 of an exhaust top 26 and the other heat exchanger 24 is in communication with an exhaust cylinder 30. Further, a fan 29 is provided midway in the exhaust cylinder 30 whose top end confronts an exhaust top chamber 31 of the exhaust top 26. In the subject hot water feeder, the fan 29 is used for a heat source giving a large amount of combustion and a natural supply and exhaust system is used for a heat source giving a small amount of combustion. Consequently, it is possible to make the hot water feeder small-sized and compact and to prevent the lowering of the stability of combustion and the thermal efficiency thereof bacause the hot water feeder is not influenced by the other heat exchanger. | ||||||
