HEAT STORAGE FLOOR HEATER

摘要

PROBLEM TO BE SOLVED: To obtain a heat storage floor heater in which the height, width and length of the floor heater allowable for the floor structure can be set to satisfy the temperature and time required for storing/radiating heat with night electric power under a state where the floor heater is laid on the floor surface by fixing planar electric resistance heating elements integrally to a thin box type case while overlapping tightly and storing heat at the connection wiring part using night power. SOLUTION: Planar electric resistance heating elements are integrated with a heat storage body while being overlapping with maximum height of 1 mm and arbitrary width and plane length and then fixed to the inside of a panel. Required number of panels are lain directly on an underlying plywood and interconnection electrically through a connector 8. Floor is finished using a flooring material which is secured to joists at the upper opposite ends of a panel 9 by means of screws and connected with a finish power supply 13. A latent heat storage material principally comprises sodium acetate hydrate and has heat quantity per unit weight of 60 kcal/l, quantity of heat per unit volume of 85 kcal/l, specific weight of 1.42 and melting point and freezing point of 58 deg.C.
