PROBLEM TO BE SOLVED: To provide a heating system which uses two kinds of heating devices, including an electric heat pump type heating device, capable of heating a room more efficiently.SOLUTION: The heating system includes a first heating device comprised of a first heating element and a combustion heat source unit, a second heating device comprised of a second heating element and an electric heat pump, a first controller, and a second controller. The combustion heat source unit is provided with a first control means, and a system control device is connected to the first control means by way of a first signal line. To the first controller, the system control device is connected by way of a second signal line, otherwise, the first control means is connected by way of a third signal line. A system control device 50 can control operation of the second heating device, with no intervention of the second controller, based on the information acquired from a first control means 11A or a first controller 30. Further, it stops operation of the second heating device if an external temperature detected with an external temperature detecting means 60 is a predetermined temperature or lower. |
