PROBLEM TO BE SOLVED: To conduct heat uniformly to the floor surface by heightening the heat conducting efficiency to the floor surface, and making uniform the temp. over the heating surface. SOLUTION: On the surface of a foundation floor made of a heat insulating material 18, a hot water pipe 20 bent in corrugation at specified periods is arranged meanderingly in such a way that the corrugated curves of two opposing parts of the pipe 20 are approx. symmetrical to the left and right. Thereby the heating effect direction decided by the hot water flowing direction in the pipe 20 is set to one direction and an oblique direction, which allows warming uniformly the floor plates arranged on the pipe 20. A heat conduction material 22 consisting of a mixture of river sand, aluminum powder, etc., is filled and arranged around the pipe 20 in the dense condition, and a radiation heat intensifying layer 24 is formed on the top face of the material 22. |
