<P>PROBLEM TO BE SOLVED: To provide a heat supply system capable of performing proper control in the object of reduction of carbon-dioxide emissions or energy cost (power cost, fuel cost). <P>SOLUTION: This heat supply system includes a control means 50 capable of selecting a heat pump priority operation mode and a burner priority operation mode, and a boiling-up temperature setting means 53. The control means 50 includes: a first calculating means 51 for successively calculating coefficient of performance of a heat pump-type heating means 10, and calculating a first amount of emission on the basis of the coefficient of performance, on the basis of a detection value of an outside air temperature, a set value of a boiling-up temperature, and at least one of detection values of a water supply temperature to the heat pump-type heating means 10 and an outside air humidity; and a second calculating means 52 for calculating a second amount of emission on the basis of heat efficiency of a combustion type heating means 20. The control means 50 selects the heat pump priority operation mode when the second amount of emission is larger than the calculated first amount of emission, and selects the burner priority operation mode when the second amount of emission is smaller. <P>COPYRIGHT: (C)2012,JPO&INPIT |
