PROBLEM TO BE SOLVED: To provide floor heating capable of performing proper heating in rooms requiring supply warm water having different temperatures in a warm water type floor heating in which a plurality of floor heatings are actuated with one heat source machine. SOLUTION: Floor heating includes a plurality of warm water circulation pipe line 52, a heat source machine 1 for supplying warm water to the plurality of the pipe lines, an intermittent water supply valve 51 for switching on and off water supply through each pipe line, a remote controller 3 for performing an instruction concerning strong and weak heating in each pipe line, and a water supply time control section 101 for changing water supply on-off time to each warm water pipe line based upon an intermittent operation table 303. The control section when there is a request to supply warm water with different temperature from the remote controller, supplies the highest temperature warm water to a pipe line of each room, and in a room where it receives higher temperature warm water supply than the required temperature, performs ON-OFF control of the water supply valve to prevent floor temperature from being excessively raised, whereby there is achieved closer heating to a request in each room.
