Putting sunlight to work for you

Following are descriptions of how various solar water heating types work:


  • Solar collectors. A pump circulates a liquid to solar collectors on the roof to absorb the sun’s thermal heat.
  • Solar storage tank. Heated liquid is pumped into coils that warm the water in the solar storage tank.
  • Conventional water heater or boiler. Hot water flows into your existing boiler or water heater for backup heating as needed.

With solar-heated water, you have hot water every day, for typical domestic needs, such as heating a swimming pool or spa, or providing space heating or cooling. You can even use it in industrial processes that use heat.
