With today’s concerns about the economy and the environment, the use of solar power to heat in-ground swimming pools is becoming increasingly popular among pool owners. However, while many people may wish to use the sun to heat their pool, they may not want to expend the time and money required to replace their entire heating system. In such circumstances, solar pool covers and reels for in-ground swimming pools provide an excellent compromise. In-ground solar pool covers use heat from the sun to increase and maintain a pool’s temperature, allowing pool owners to enjoy significantly reduced heating costs as well as several other benefits.
