Solar Heat for Pool and Spa
The typical pool system uses an unglazed collector. The area of the collector is usually about 80% of the surface area of the pool. It will add about 3 months to the unheated swimming season. When the sun is out water from the pool is circulated through the collectors heating it. In many cases the pool has an attached spa. Valves can be turned so that the solar heats the spa.
