Vacuum tank stores heat. Vacuum tank stores heat.
An efficient long-term heat storage tank boosts the shares of fraction of solar thermal energy systems in buildings. Staff at Bavarian Center for Applied Energy Research and at steel and metal engineering company Hummelsberger have developed a storage system that minimises thermal losses and optimises temperature stratification. A vacuum between the inner and outer tank combined with a perlite powder filling reduces the thermal conductivity of the storage tank shell. The long-term heat storage tank is already being used for heat supply in single-family homes and apartment buildings.
