Sun → Collector → Tank → Hot water
How a solar water heater works
Solar collectors absorb heat from sunlight and transfer it to the water in your storage tank, so hot water is ready when you need it — without running an electric heater.
What it is
Reliable solar water heating solutions
Solar water heaters provide an energy-efficient solution for heating water using renewable solar energy, helping reduce dependence on conventional electricity for hot-water requirements.
Heating water is one of the largest electrical loads in most households — which is exactly why it is one of the easiest to move to solar. A correctly sized system heats water through the day and stores it, so hot water is available when you want it without running a geyser.
