An efficient long-term heat storage as the Vacuum Super Isolated Solar Storage Tank (VSI storage) increases the profit
margins of solar thermal systems in buildings. It can store the heat for several weeks or even months. Thus high solar
profit margins for small and medium-sized existing buildings can be achieved. This type of storage tank is available
with a capacity of 5 to 50 cubic meters.

an inner and outer tank made of steel.
A vacuum between the inner and outer tank reduces
* Perlite is a naturally occurring material of volcanic origin with low density and high porosity. Therefore it has good insulating properties, even without evacuation. Another advantage is the temperature resistance up to 800 °C. The material is non-poisonous and non-flamable.
