PROBLEM TO BE SOLVED: To provide a heat storage type electric floor heating system facilitating creating of a comfortable heating environment at a lower working cost and moreover, regardless of environmental conditions at a lower maintaining cost with a simple structure by improving a defect of the prior art. ;SOLUTION: In a heat storage type floor heater, a heating body 4 adapted to generate heat by supplying electric energy is buried into a heat storage body 3 composing a floor part 2. When the heat storage type floor heater is initially used or its use is started after a long unuse period, after the start of the operation of energizing the heat storage body 3 during the period lower in power charge, the energizing operation is continued until the surface temperature of the heat storage body 3 reaches a desired temperature predetermined regardless of whether the period lower in power charge ends or not.;COPYRIGHT: (C)1998,JPO
