PURPOSE:To enhance the saving effect of energy consumption in a heat exchanger, by performing a sufficient heat exchanging operation by exchanging heat from waste smoke containing heat, exchausted from a stove in many stages in a water tank and in spiral heat exchanging parts. CONSTITUTION:The waste smoke containing heat from a stove 2 is discharged to the atmospheric air via a waste smoke pipe 2A, a flue duct 3, and a heat exchanging chamber 12. On the other hand, the water being fed from a feed water pipe 15 is fed into a heat exchanging part 14, and is fed into an upper tank 13 being heated, and then is fed into a heat exchanging pat 7 passing through a feed hot-water pipe 17 after being heated up further. In the heat exchanging part 7 the water is heated up further by the flue duct 3 surrounding the heat exchanging part 7, and is led to a kitchen, a bath tub, and other places for use. |
