Harris’ 16 ft x 24 ft Oval Solar Covers are the environmentally friendly way to raise your pool temperature and maintain heat, without breaking the bank on your heating bill. Harris' Blue Solar Covers allow the sun to penetrate and warm the pool; unlike experimental solar covers that feature thick, reflective, aluminized coating and reflect the sun away from your pool. Harris' Solar Covers last longer because they maintain their flexibility and don't become brittle like dark colored, opaque blankets. Harris' Solar Covers allow the warm UV rays to penetrate your pool directly; raising water temperatures by up to 15° Fahrenheit. Plus, the cover helps seal in the heat to maintain optimal pool comfort when the pool is not in use. Pool owners love the blue color of their pool water, and our Harris Solar Covers let the blue shine through. Keep dirt, silt, and debris from entering your pool, and prevent chemicals from depletion due to exposure.8 Mil Covers include 3 year warranty, 1 year full.
