Solar Hot Water Systems use abundant, free energy from the sun to heat the water in your home, saving money on your fuel bills.
Solar water heating or solar thermal involves utilizing solar panels to harvest the heat of the sun and transfer it to the water used within the home. On sunny days a solar thermal system could provide all of your hot water, and will typically provide around 70% of a homes hot water requirements, if sized and designed correctly.
How does it work
Solar thermal technology augments conventional water heating systems running on expensive and dirty fossil fuels, with clean energy provided for free by the sun’s rays. Heat gets absorbed through the solar collectors and transferred with the aid of a special solar fluid to heat the homes hot water cylinder. This reduces the amount of fuel required to bring the hot water up to the desired temperature, saving money on heating bills and reducing household carbon emissions.
Illustration of a domestic solar water heating system.
Thermal energy from the sun heats fluid circulating through solar collector panels mounted on the roof. The fluid passes through a heat exchanger coil in the hot water tank, heating the water. A boiler is used to heat water in the tank when there is insufficient solar energy.
