Solar thermal collectors

Solar water heating systems, or 'solar thermal' collectors, use free heat from the sun to warm hot water

Solar Thermal Collectors

Solar thermal collectors are products that are specifically designed to capture solar energy and convert it, with a broader solar system, to useful heat for water or space heating applications. They are built around a solar absorber that uses radiation to increase the temperature of heating fluid flowing through the collector. This heat is then transferred to a storage vessel by means of a circulating fluid, or in some instances, the solar collector could be directly connected into the heating circuit.
