PURPOSE:To provide sufficient heating to a room, by fitting solar heat collecting plates to the outer side of a wall body, by contacting heat pipes to the heat collecting plates, by radiating heat to the room by the intermediary of a heat accumulating material, and also by providing a hot water pipe for an auxiliary heating medium to the heat pipes. CONSTITUTION:In a day time when solar heat is sufficiently radiated, the solar heat X is absorbed by heat collecting plates 4, and is transferred to fins 9 by the intermediary of heat pipes 5. A part of the heat absorbed is transferred to the whole body of a wall 1 by horizontal heat pipes 8, and is uniformly accumulated in a heat accumulating material 2. The heat accumulated in the heat accumulating material 2 is radiated into a room. On the other hand, in a day time when solar radiation is not enough and the heat is not sufficiently accumulated in the heat accumulating material 2, the heat from a hot water pipe 7 is transferred to the horizontal heat pipes 8 and is accumulated in the heat accumulating material 2 by the intermediary of the fins 9 to be radiated into the room. |
