PURPOSE:To conserve energy by a method wherein a radiating pipe is connected with the upper end of a boiler of a solar heat collector through a hot water supply pipe and a water return pipe, while the hot water heated by solar heat is circulated through the radiating pipe by natural convection and a heating panel under the floor is operated. CONSTITUTION:Water is heated by a solar heat at a boiler portion 13 of a solar heat collector 1 utilizing water as a circulating liquid. The thus heated water is circulated from a hot water supply pipe into a radiating pipe 3 corresponding to the evaporating portion 11 of a heating panel 2 by natural convection, caused to radiate heat for operating the heat panel 2, and returned to the boiler 13 through a return water pipe. The floor is heated by radiation of heat from the surface of the heat panel 2. Accordingly, energy is conserved without need of any other power than the solar heat.
