PROBLEM TO BE SOLVED: To obtain an optimum floor temperature and rooms temperature without providing a particular air layer and without adjusting the thickness of a covered mortar layer by providing a heat storage heating layer composed of a heat storage member and an electric heater on a floor undercoat member, and further providing a heat insulating member between the heat storage heating layer and a floor finishing member. SOLUTION: A floor heating structure is adapted such that a heat storage heating layer 2 composed of a heat storage member board 2a and an electric heater unit 2b is provided on a floor undercoat member 1 composed of a heat insulating member laid on a slab 1a. A heat insulating member 3 is provided on the heat storage heating layer 2, and a floor finishing member 4 composed of a concrete 4a and a surface finishing member 4b is provided on the heat insulating member 3. As the heat insulating member 3 there is used one which has a thermal conductivity lower than that of the floor finishing member (or covered mortar) 4 and further has compression strength to some degree, and which is stable against moisture absorption from the concrete 4a. |
