Underground seasonal heat storage for a solar heating system

A solar assisted district heating system with underground seasonal heat storage is used for heat supply. A solar contribution of about 50 % to the total heat demand (space heating and domestic hot water) is planned. With this system a duct beat store with temperatures up to 80°C without heat pump is realized for the first time in Germany.
