To provide a floor heating system capable of improving room temperature adjustment performance to reduce energy consumption.SOLUTION: A cycle time of a floor heating system 2 is set within a range of 30-60 min, and an ON time of a thermal dynamic valve 24 is subjected to duty control, so that hot water is intermittently supplied from a heat source 23 to a floor heating panel 21, wherein the thermal dynamic valve is installed in a circulation circuit 22 connecting the heat source 23 and the floor heating panel 21. Then, when 20 minutes elapse after starting the cycle time, in a case where the temperature deviation obtained by subtracting a setting time from a room temperature is not more than -1.0°C, the cycle time and a duty ratio are reset, and the duty control is started over.SELECTED DRAWING: Figure 3 【課題】室温調整性能を向上させ、消費エネルギーを低減できる床暖房システムを提供すること。【解決手段】床暖房システム２のサイクル時間を３０分以上６０分以下の範囲内で設定して、熱源機２３と床暖房パネル２１とを接続する循環回路２２に設置した熱動弁２４のＯＮ時間をデューティ制御することにより、熱源機２３から床暖房パネル２１に温水を間欠的に供給する。そして、サイクル時間を開始してから２０分が経過したときに、室温から設定時間を減算した温度偏差が−１．０℃以下である場合には、サイクル時間とデューティ比をリセットして、デューティ制御をやり直す。【選択図】 図３
