PURPOSE:To quicken the rise of room temperature and to increase the operating efficiency, by installing a heating source, with which a sensor to prevent incomplete combustion is provided and from which hot-air can be taken out, inside the building, in a hot- water floor heating apparatus. CONSTITUTION:A sensor 11 made of SnO2, to prevent incomplete combustion, is provided in the neighborhood of a combustion surface 10, and an automatic quenching device is connected to the sensor 11. An inversible ventilating fan 14 is provided above a heat exchanger 5. A heating source 1 is connected to a hot-water panel 2 through a forward pipe 3 and a return pipe 4, and both the heating source 1 and the hot-water panel 2 are installed inside the building in order to quicken the rise of temperature. When an operation is started, a circulating pump 8 is actuated to circulate water. At the same time, the ventilating fan is turned round and combustion is started to heat the circulating water. Normally, combustion gas, passing through a combustion chamber 6, transmitting heat to the water in the heat exchanger 5, is exhausted from a vent port 15. During this time, the ventilating fan 14 is turning in the positive direction. The air in the room can be heated in a short time when the fan 14 is turned round in the reverse direction to introduce combustion gas to a hot-air blow-off port 13, passing through a hot-air passage 12. |
