Get more energy for pools with a solar cover The u.S. Department of energy has stated that a pool cover is the single best way to reduce heat loss on a pool. By limiting unnecessary evaporation, you'll save energy and still be able to enjoy swimming in a warm pool. 2. Extend your swimming season A pool cover will help keep your pool warm when the air temperature cools off at night. This dramatically cuts down on heating costs and can extend your swimming season by several months. -
