Dust and other unclean things are captured when passing through the adsorption filter plate 262. The cleaned hot gas enters the heat absorbing plate 20 along the ventilation pipe made of Teflon material. The hot water after heat exchange is stored in the storage tank 31 through the pipe 2 30 until it reaches the upper limit set by the temperature sensor 331, the pressure sensor 332 and the water level monitor 333.
