Solar thermal is a well proven technology delivering energy and carbon savings
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.
Solar Thermal Components
Solar thermal collectors capture the sun’s energy by heating a fluid contained within reinforced glass pipes. Collectors come in two types; flat plate and evacuated tube. Each has it’s own advantages and we will recommend the most appropriate type for your property.
Pump and controller
The pump ensures the transfer fluid is circulated between the collectors and the water cylinder efficiently. While a system control panel controls the pump and provides information on the system’s performance, as well as any faults should one develop.
The heat captured by the solar thermal collectors is pumped to a coil in the water cylinder. A solar thermal water cylinder has a dedicated coil that allows the heat from the collectors to be transferred as efficiently as possible.
