The 21 ft Round Heat Wave Solar Blanket Swimming Pool Cover is an essential investment for every pool owner. Designed to increase pool water temperature by 10 to 15 degrees (or more in season), this solar blanket significantly reduces heating costs by up to 80%. It offers superior heat absorption and retention, reducing evaporation and saving water and costly chemicals. The blanket is made from a durable polymer material with thousands of tiny sealed air bubbles that float on the surface of your pool water and allow solar energy to pass through, which is then trapped as retained heat in the pool. This solar blanket extends your swimming season by up to 6 weeks and comes with a 4-year manufacturer's warranty. Made in the USA with 8 mil thickness and UV stabilized polyethylene, this blanket is a durable and long-lasting solution for your pool. The solar reel is not included in the product. The dimensions of the blanket are 21' diameter, perfect for round pools. Please note that the photo displays a rectangular solar cover that has been custom cut by a customer to fit their pool and this listing is for a round solar cover.
