Energy free of charge

Whether you are planning a new build or want to modernise your heating system, we would always recommend incorporating a solar system because solar energy is a free and inexhaustible source of energy. A Windhager solar system is a very efficient way to tap into solar energy. SolarWIN flat collectors also offer an impressive high-quality design and long life. And they are flexible too: SolarWIN is therefore suited to both in-roof and on-roof installation.
