PROBLEM TO BE SOLVED: To provide a floor heating system capable of securing the internal space of a building as wide as possible and ensuring high heat utilization efficiency.SOLUTION: A roof roofing material 5 is provided on a roof surface 4a of a building 1 with an air flow layer S interposed between the roof surface 4a and the roof roofing material 5, a heat exchanger 30 is provided in the building 1, and an air flow path 10 feeding air of the air flow layer S to the heat exchanger 30 is spread from the air flow layer S to the heat exchanger 30. A radiation tube 42 is provided in an underfloor 17 of the building 1, and a circulation pipe 41 is arranged between the heat exchanger 30 and the radiation tube 42. The heat exchanger 30 moves heat of the air fed into the heat exchanger 30 via the air flow path 10 by a liquid heat medium fed into the heat exchanger 30 via the circulation pipe 41, and heat of the liquid heat medium fed into the radiation tube 42 via the circulation pipe 41 is radiated to the underfloor 17 of the building 1 via the radiation tube 42. |
