PURPOSE:To obtain desired comfort in the indoor temperature distribution, to reduce the installation cost and to facilitate maintenance and inspection of the titled heating device by filling a circulation flowpath formed by a main heating part, a radiator, an auxiliary heating part and circulating pump with a liquid such as ethylene glycol having a high boiling point and a small specific gravity as a heat medium. CONSTITUTION:The heat medium 5 heated in the main heating part 2 is introduced into a radiator group 1a by means of the pump 3. The heat medium 5 which radiates heat in the radiator group 1a and lowers its temperature, flows into the auxiliary heating part 4. Since the heat medium 5 has a small specific heat and an electric heater is formed in a small size, the heat medium 5 can be heated to a high temperature. Therefore, the heat quantity lost can be supplemented in an extremely short period of time. The re-heated heat medium 5 flows into a radiator group 1b in which the heat medium 5 radiates heat and returns to the pump 3. The radiation quantities of the radiator groups 1a and 1b become uniform. As the heat medium 5 filled in the circulating flowpath, ethylene glycol and triethylene glycol are used suitably. |
