A solar thermal system works by harnessing is the sun’s energy and converting it into heat which is then transferred into your home or businesses heating system as hot water or space heating.
Solar thermal panels are used in conjunction with a boiler, collector or immersion heater. The solar collector will use the sun’s rays to heat a transfer fluid which is a mixture of water and glycol, to prevent the water from freezing in the winter. The heated water from the collectors is pumped to a heat exchanger inside a water cylinder. The heat from the exchanger will then heat the water inside the cylinder.
After the liquid releases its heat, the water will flow back to the collectors for reheating. A controller will ensure that the fluid will circulate to the collector when there is sufficient heat available. Solar thermal technology is proven, reliable and low maintenance.
