The heat released from the space member A becomes radiant heat via the space A, and the floor material 9 can be heated.

In addition, in the case of the above-described regenerative floor heating device, since the heat release from the heat storage material cannot be controlled, for example, there is no person in the room for 24 hours, and a living room which does not need heating when going out or sleeping. In such cases, a certain amount of heat is continuously emitted. Therefore, there is a problem that the running cost is increased, and it is necessary to always operate the heater at a constant interval in preparation for a necessary case, so that there is a problem in terms of economy and energy saving. Also, since the outside temperature is high and heating is not required, for example, in the early spring or autumn, or during the day when the temperature becomes high during the day, the heat release from the heat storage material cannot be controlled, so the room temperature becomes too high.
