Solar Thermal Panels
Heat your hot water using free energy from the sun — solar thermal panels can meet up to 70% of your annual hot water demand and work brilliantly alongside heat pumps.
What Are Solar Thermal Panels?
Solar thermal panels — also known as solar water heating systems — use energy from the sun to heat water for your home. Unlike solar PV panels which generate electricity, solar thermal collectors absorb heat directly and transfer it to a hot water cylinder via a pump and heat exchanger. The two most common types are flat-plate collectors and evacuated tube collectors.
A well-sized solar thermal system can provide up to 70% of a household's annual hot water needs, with the highest output during spring and summer. In winter, the system still contributes, but a backup heat source such as a boiler or heat pump tops up the supply. Solar thermal is an excellent complement to heat pump installations, reducing the electrical load on the heat pump and improving overall system efficiency.
