PURPOSE:To circulate heating medium smoothly and prevent the generation of noise in a heating device having a secondary heating medium circuit utilizing phase changes by a controlling method wherein after the heat supply source is started a pump installed in the heating circuit is started. CONSTITUTION:The heating system is arranged such that the heating medium flowing through a piping 8 of a heating circuit 2 is heated to vaporize by the heat supplied by a heat supply source 1 through a heat exchanger 3 and the gasified medium flow into a radiator 4 where it radiates heat which heats the room. Subsequently, the liquefied heating medium flows through a liquid receiver 5 and a piping 7 back into the pump 6. Further, when starting the heating system, th heat supply source 1 and the pump 6 are arranged to be rendered ON and OFF with a time lag. In brief, the heat supply source 1 is first turned ON to allow the vaporized heating in the piping 8 to flow through it into the radiator 4, whilst the heating medium in the piping 7 is allowed to flow into a liquid receiver 5 so that the suction side of the pump 6 may be filled with liquid medium, and then the pump 6 is turned ON to allow the heating medium to circulate through the heating circuit 2. |
