PURPOSE: To enable reversed double surfaces of a heat accumulating floor heating panel to be used, increase an amount of accumulated heat or provide an additional heating function by a method wherein a heater device and a heat accumulation device arranged in the heater device are closely contacted between an outer layer at a surface and an outer layer at a rear surface.
CONSTITUTION: A heater device 6 comprised of a sheet-like heater 1, a uniform heat radiator 2 and an electrical insulator 3 is closely contacted with a heat accumulation member 4. The electrical insulation member 3 composed of insulating bag or insulating sheet electrically insulates the sheet-like heater 1 having the uniform heat radiator 2 and protects it against any external force. In the case that a floor heating system having an additional heating function is applied, the heater device 6 is set to face against the floor member 7. In the case that a capacity is poor under a heat accumulation amount of the heat accumulation member 4, the panel is reversed, the heater device 6 is held by the heat accumulation members 4, an incremented heat accumulation member 9 is arranged at a lower part of the heat accumulating floor heating panel and a thermal insulating material 8 is placed at the lower part.
