Solar Thermal panels have an odourless,
non-toxic glycol/water solution circulated through pipes inside the panel. The fluid is heated by the sun and then piped through a coil in the specially installed water cylinder, transferring it's heat to the water. The fluid - now cool - is then pumped up to the thermal panel to continue the process. As it's a thermal process, the panels can still operate - at a reduced rate - in cloudy, hazy or overcast conditions. In combination with a boiler or immersion heater, the water is then be heated to the 60 degrees centigrade set by the
cylinder's thermostat.

An average household of four people needs only two panels (covering approximately 4.5m²) on a south-facing roof, to provide up to 70% of your hot water needs per year.
