PURPOSE:To provide the titled heating device which requires no drive power for circulating a heat source forcibly through a heating circuit by a method wherein the heating circuit for a heat pump is provided. CONSTITUTION:The heat medium 22 in a heat pump 23 is heated to vaporize by hot water in a vaporization zone 26 within a tank 3 and transfers to a low pressure heat radiation zone 27 where the heat medium 22 transmits heat to a heat medium 12 in an outer pipe of an evaporator 14 and cools to be liquefied. The heat medium 22 in the heat pump 23 thus liquefied returns to the vaporization zone 26 again through a wick (not shown) or due to gravity and is heated again by the hot water to evaporate. Thus, by the repetition of the above-mentioned cycle, the heat pump 23 transmits the heat of the hot water in the tank 3 to the evaporator 14 of the heat pump 23. |
