Abstract

A heat storage apparatus for a temperature range of about 10 to 95 degrees Celsius, especially for solar installations, heat pumps, boilers or the like and for extraction of heat for the operation of a room heating installation and/or an installation for water for use, consists of a low-temperature latent heat storage device and a downstream water reservoir. In that case, the fresh water feed for the installation for water for use runs, for preheating, through the low-temperature latent heat storage device before entry into the water reservoir and the return of the heat exchanger runs, for further cooling down of the return flow to the lowest possible temperature level, through the low-temperature latent heat storage device after exit from the water reservoir.
