PROBLEM TO BE SOLVED: To provide a latent heat storage material composition suitable for simple floor-heating devices or wall surface-heating devices which can correspond to the increases in the thickness of floor portions, carpets or the like on the recent floor-heating devices and set the melting point of the heat-storage material to 40-45 deg.C, and to provide a heating device using the same. SOLUTION: (1) This heat storage material composition comprises (a) 50-89 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, (b) 10-30 wt.% of sodium bromide, and (c) 1-20 wt.% of at least one compound selected from sodium lactate, sodium glycolate, sodium formate, sodium propionate, 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. |
