Abstract
A heat storage system intended for long term storage between seasons of surplus heat collected in a solar energy system for example, comprises one or several networks of ducts laid out in an earth pack, e.g. underneath a building to be heated and in between foundation members thereof. The system economizes as to expenditure of space and material, in particular with respect to storage of heat at a relatively low temperature level as is encountered in solar energy systems.
