Understanding solar hot water
How solar hot water works
Solar hot water systems use the sun's free energy to heat your water, providing up to 80% of your hot water needs.
Panels collect the sun
Roof panels contain collectors that absorb the sun's heat. A heat-transfer fluid carries that heat down to the water storage tank.
The tank stores the heat
The heated fluid warms the water in a storage tank, so you have hot water ready whenever you need it.
Electric boost tops it up
On cloudy days, an electric boost element tops the water up to temperature, so you always have consistent hot water.
Cut your energy use
Because the sun does up to 80% of the work, you dramatically reduce the energy needed for hot water and improve your home's energy rating.
