SGE is a compact installation with integrated solar heat exchanger. Apart from its excellent suitable size for restricted spaces, the SGE is also a very efficient appliance. The collectors are connected to the lower heat exchanger, and the heat is transferred from the collectors to the water. The upper heat exchanger afterheats, if necessary, until the water has reached the desired temperature. In this installation the solar contribution is fully utilized. If a higher draw-off temperature is required than can be provided by solar contribution, only then additional gas heating is needed. This functionality delivers the optimum use of solar energy and a minimum use of gas.
