The work involved studying the potential of Na 2 SO 4 , NaCl, KCl, CaCl 2 and some eutectic mixtures of inorganic salt for storing thermal energy. Heat storage materials have wide application in devices such as “off‐peak” space heating furnaces. Data reveal Na 2 SO 4 to be a better heat storage material than other salts as well as conventional heat storage materials because of its dimorphic nature and high heat of transition. It is estimated that less than 0.29 m 3 of Na 2 SO 4 would be required for heating a normal sized house on the Canadian Prairies.
