Groundbreaking storage logic and
Forstner waste heat recovery

In 2012 the Earth's population exceeded 7 billion. If we regard it as a whole, in contrast to the power of the sun its natural resources are not endless. We need to move towards the use of renewable energies and intelligent use of heat recovery systems.

Forstner Speichertechnik GmbH has been planning and manufacturing innovative accumulator, storage tank and heat recovery solutions since 1998.
Forstner Speichertechnik is a competent partner for its customers and provides support during the planning phase through to the installation of accumulator and storage tank solutions for solar, heat pump, pellets and gas systems in industrial and municipal facilities, hotels, sport facilities and private households. We elaborate the ideal energy concept, taking the specific customer requirements, the system hydraulics and the control technology into account.
