PURPOSE:To largely save fuel cost, by combining a hot water supplier to feed hot water into a bath tub with an air heating apparatus. CONSTITUTION:The heat radiated from a combustion body 1 is released to the outside from the gap of each pipe, as well as to hit the surface of a staggering hot water pipe 4 fitted to the heat radiating surface of a combustion body 1. Water is fed into a water tank 5 through a hose 6 which is connected to the tap of a city water. It flows through the hot water pipe 4 which is heated by the combustion body 1. The water fed from one end of a hot water pipe 4 becomes hot water while it is flowing staggeringly through the pipe under the water pressure as shown by dotted arrow signs, and is led into a bath tub passing through a connection pipe 7. With such an arrangement, hot water supply and air heating can be performed at the same time, so that fuel cost can largely be saved. |
