A clean and highly efficient means of using renewable energy from the sun, solar thermal is used to provide a cleaner and more environmentally friendly alternative for providing heating and hot water used in the home. Solar collectors will be 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 200ºC but also will not freeze in temperatures down to -25ºC. 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. Solar water heating depends on radiation, not direct sunlight, and so works on dull days.
