GAME SolarPRO CURVE is designed to increase your pool temperature 5 degrees in five days, extending the pool season! The Curve design creates a maximum solar collecting area that captures FREE heat from the sun even as the position of the sun changes! The Curve is made from a super strong blow-molded plastic frame with a clear cover that locks in heat and deflects cooling winds. The Curve easily connects to in-ground or above ground pools and multiple units may be joined for even more heat. For multiple heaters use the GAME bypass kit listed below. Results based on 12K gallons and outside temperature of 74-82 degrees F.
