Solar Thermal System

Roof-mounted solar thermal collectors are connected to one of the coils of a twin-coil cylinder using a sealed circuit containing a special glycol/water solution. This fluid not only withstands the high temperatures in excess of 200°C on a summer day, but also will not freeze in temperatures down to –25°C. The pump in the system circulates the heated fluid from the panel to the cylinder where the heat is transferred to the stored water through the lower coil.
