PURPOSE:To reduce heat loss due to heat dissipation at night by a method wherein a heat receiving tank is communicated with water heating section mutually through the sending pipe of heat medium and a returning pipe of the heat medium. CONSTITUTION:The device 1 is provided with an outer casing, accommodating the heat receiving tanks 6, 46 arranged so as to receive heat from a heat collecting body 45 and a condensing section 45a, and the water heating section 43, arranged at the outside of the outer casing 4, while the heat receiving tanks 6, 46 are communicated with the water heating section 43 mutually through the heat medium sending pipe 16 and the heat medium returning pipe 17. The heat collecting body 45 and the heat receiving tanks 6, 46 have no place to be welded respectively, therefore, the production thereof is easy and leakage of liquid is not readily generated while the repairing of them are simple even when the leakage of liquid is generated since the heat collecting body 45 and the heat receiving tanks 6, 46 are separated mutually. Further, solar heat can be absorbed in the surfaces of the heat receiving tanks 6, 46, therefore, the heat collecting performance thereof is excellent and the heat loss due to the heat dissipation during night may be reduced. |
