The cover raises the water temperature by up to 8 °C and retains heat in the pool for significantly longer. It reduces heating costs by up to 70% and decreases water evaporation by up to 90%. Additionally, it lowers chemical consumption and is suitable for easy and frame pools. The solar cover also keeps the swimming pool clean. It intentionally features small holes in the center to allow for air and water exchange and to prevent the water from becoming stagnant. Furthermore, the solar cover cannot sink in the water during rain. For maximum effectiveness, the air bubbles should face downwards. The solar pool cover sits directly on the water, significantly reducing water evaporation and protecting the water from contaminants. Due to reduced evaporation and heat gain, the costs for the solar pool cover are recouped within a swimming season. It is suitable for rectangular frame pools.
