What customers say
Customers frequently commend this solar pool cover for its impressive effectiveness in warming pool water and significantly reducing evaporation, which helps lower heating expenses. Many users observe a tangible temperature rise, enhancing their swimming experience. While its primary function receives strong approval, opinions on its long term resilience show some variation. Some users find it sufficiently robust for a few seasons, yet others voice concerns regarding the material's ability to withstand prolonged sun exposure and regular handling, suggesting its "heavy duty" designation may not always align with multi year expectations.
Know before you buy
The cover uses thousands of tiny air bubbles to capture and transmit solar heat into your pool water. It also acts as an insulator at night, preventing heat loss through evaporation.
This cover is specifically sized for 21-foot round pools. If your pool is slightly smaller, you can easily trim the polyethylene material with a pair of heavy-duty household scissors to achieve a perfect fit.
While its primary purpose is heating and insulation, the cover will certainly block leaves, dirt, and insects from entering the water. However, it is not designed as a safety cover and will not support the weight of a person or pet.
To maximize the 3-year lifespan of the material, store the cover in a shaded, dry area during the off-season. Avoid leaving it folded in direct sunlight when it is off the pool, as this can degrade the polyethylene.
Yes, the heavy-duty polyethylene material is designed to withstand standard pool chemicals. Just ensure your water chemistry is properly balanced to prevent premature wear on the cover.
