Solar Swimming Pools
Solar pool heating is the most cost-effective use of solar energy in many climates. A solar pool heating system usually costs between $3,000 and $4,000 to buy and install.
Most solar pool heating systems include the following:
- A solar collector — the device through which pool water is circulated to be heated by the sun
- A filter — removes debris before water is pumped through the collector
- A pump — circulates water through the filter and collector and back to the pool
- A flow control valve — automatic or manual device that diverts pool water through the solar collector.

Solar pool collectors are made out of different materials. The type you'll need depends on your climate and how you intend to use the collector. If you'll only be using your pool when temperatures are above freezing, then you'll probably only need an unglazed collector system.
The proper installation of a solar pool heating system depends on many factors. These factors include solar resource, climate, local building code requirements, and safety issues. Therefore, it's best to have a qualified solar thermal systems contractor install your system.
