Sun2Solar Blue 18 ft x 36 ft Rectangle Pool Solar Cover - Heat Safety

Our review of the Sun2Solar Blue 18 ft x 36 ft Rectangle Pool Solar Cover finds it best for pool owners who want a low-effort way to raise water temperature and cut evaporation. The single biggest reason to buy is its simple solar heating function: the cover uses sunlight to warm water by several degrees while also reducing overnight heat loss and limiting evaporation. For those seeking an affordable seasonal solution to keep pool water warmer and cleaner with minimal installation, this cover delivers straightforward performance.

Key Features

• Free Solar Energy: Uses direct sunlight to raise pool temperature, offering a passive way to increase comfort without adding equipment.
• Traps Heat: The material holds warmth after sunset, helping to maintain a more consistent water temperature overnight.
• Conserves Water: Reduces water evaporation by up to 95%, which in turn lowers chemical use and the need to top off the pool.
• Debris Prevention: Stops leaves and larger debris from entering the pool, cutting down on routine cleaning and skimming.
• Easy Installation: Durable design with extra overlap and six heavy-duty grommets makes fitting and removal simple for above ground and inground rectangular pools.

Who It's For

This pool blanket is ideal for owners of rectangular inground or above ground pools who want a no-fuss way to raise water temperature by several degrees and reduce evaporation without installing a heater. It suits seasonal users and those who prefer a simple, low-maintenance accessory to improve swim comfort and lower ongoing water and chemical costs.

It is less suited for buyers who need a long-term heavy-duty commercial solution or expect a multi-year, maintenance-free lifespan regardless of handling; some users report variable durability and varying opinions on value for money, so heavy daily use or rough handling could expose limitations.
