PURPOSE: To provide a less-expensive tank and improve a heat generating efficiency by a method wherein fluid is circulated by a pump through a pipe passage communicating between a tank storing the fluid and a heat radiating pipe and a heater for beating the passing fluid is installed neat the pipe passage. CONSTITUTION: Each of the supplying pipe passages 12 to 15 is heated by a heater 16 and water W is heated when the water is flowed. The heated water W passes through a supplying connecting pipe passage 9 and forcedly fed from a flowing-in port 8a to the heat radiation pipe 8. The water W flows in the heat radiation pipe 8, thereafter forcedly fed from the discharging port 8b to a reducing connecting pipe passage 10, the water is returned back again from the returning port 1c into the tank 1. The water W is circulated so as to perform a heating at a floor 6. Since the heater 16 is not stored in the tank 1 so as to constitute a floor heating device, a capacity of the tank 1 can be reduced and the device can be reduced in its size, and then an amount of use of water W can be substantially reduced. As a result, it is possible to make a fast heating of the water W and a rising of the floor heating just after turning on a power supply can be made fast. Accordingly, it becomes possible to perform a high efficient heating with a low consumption electrical power. |
