Solar pool heaters work by sending water from the pool through solar panels using your existing pool pump. Pool water is redirected to the solar panels in order to absorb solar radiation in specially designed solar collectors. See our interactive graphic to learn more about how solar pool heating panels work.

1. Cool pool water enter the system through existing pool plumbing.
2. Your existing pool pump circulates pool water through solar panels on the roof.
3. A solar bypass valve manifold is installed to allow you to bypass the solar panels when your pool reaches the desired temperature.
4. An optional solar controller (or your existing automation system) diverts water to the solar panels when solar pool heating is desired and possible and shuts off the solar energy system when the desired temperature is reached.
5. Pool water passes through the solar panels, heating the water inside.
6. Heated water returns to the pool through your existing pool plumbing.
