PROBLEM TO BE SOLVED: To provide a latent heat storage material composition suitable for floor-heating devices, wall surface-heating devices or heat storage type air conditioning systems which can correspond to the increases in the thickness of floor portions, carpets or the like on the recent floor-heating devices, set the melting point of the heat-storage material to 48-53 deg.C and use electric heaters or heat pumps, and to provide a heating device using the same. SOLUTION: (1) This heat storage material composition comprises (a) 80-90 wt.% of an aqueous solution containing sodium acetate trihydrate or anhydrous sodium acetate in a concentration of 52-60 wt.% converted into the anhydrous sodium acetate, and (b) 10-20 wt.% of at least one compound selected from sodium lactate, D-glucose and D sorbitol. (2) The heat storage material composition preferably further contains a solid-liquid separation-preventing agent and/or a supercooling-preventing agent. |
