Get PriceOne of the most common uses for solar water-heating is to heat pool water. Pool solar collectors are lighter in weight — usually made of UV-resistant polymers — and less expensive than DSWH systems. The size should be 50 to 100 percent of the surface area of the pool. The more solar collector area, the warmer the pool will be in cool weather.
