Abstract
The increase in volume of a heat storage medium comprising water or a first eutectic mixture of water and a salt hydrate, when such storage medium passes from the liquid to the solid state, is prevented from occurring by adding 1 to 6% by volume of a second water-salt hydrate eutectic having a lower freezing point to the storage medium.
