A heat storage unit in the form of a cylinder is provided with a removable end closure, and contains a plurality of closed tubes holding a heat storage substance, the tubes being supported at either end thereof by screens. A transfer fluid flows from one end of the cylinder to the other between tubes for transfer of heat. A heat storage system is provided by the combination of a plurality of units, the units containing heat storage substances of various melting temperatures, thereby providing for the storing of heat as the latent heat of fusion at several temperature levels. |
