PROBLEM TO BE SOLVED: To provide a floor heating system, in which hot water can be sufficiently circulated in each floor heating panel even if a large number of floor heating panels are disposed. SOLUTION: Hot water from an outlet opening 9 of a heat source machine 1 flows in the order of hot water piping 10, a header 11, each hot water piping 20, a separate header 22 in each room, each hot water piping 25, each floor heating panel 30, hot water piping 28, a separate header 27 in each room, hot water piping 26, a header 12, hot water piping 13, and an auxiliary pump 14. A portion of return hot water discharged by the auxiliary pump 14 flows in the order of hot water piping 15, a return opening 2, piping 3, a circulation pump 4, a heat exchanger 5, piping 7, the outlet opening 9, and the hot water piping 10. The remaining portion of the return hot water directly flows into the hot water piping 10 via a bypass line 16, merges with hot water from the outlet opening 9, and flows toward the header 11.
