DUO line (2-storage solar installation)

The quality solution for the individual space heating and hot water demand

The DUO line solar energy systems are individually optimized according to the needs of our customers. Utilization of a solar storage tank in combination with a buffer storage tank and the hence consequently separated temperature levels for hot water and space heating, enable a maximum yield.
