Wesiti Solar Pool Covers 5 ft Discs — 9-Pack 16 mil Floating Heater Blankets for Pools & Spas, Reduces Evaporation

Wesiti 5 ft Solar Pool Cover 16 Mil is a set of nine circular heater blankets designed to float on water and help retain pool and hot tub heat while reducing evaporation and debris entry.

This nine-piece solar cover pack from Wesiti gives owners of above-ground pools, spas and irregular-shaped pools a modular, easy-to-use way to insulate water surfaces. Each disc measures approximately 5 ft (1.5 m) in diameter and is made from a 16 mil material intended for durability and repeated floating use. Use the bubble side down so the discs sit on the water surface; covering most of the pool area helps maximize benefit.

How do these solar discs help keep my pool warmer?

Placed bubble-side down on the water, the covers reduce heat loss from the surface and limit evaporation, which together help the water retain warmth from sunlight and any existing heating system. They work best when they cover a majority of the surface, minimizing open water exposed to air.

• 16 mil thickness for added puncture resistance and longer service life
• Bubble-side down floats directly on water to trap heat at the surface
• Multiple discs allow coverage of irregular and round pools by overlapping
• Reduces evaporation, conserving water and maintaining temperature

Will the Wesiti covers fit my pool or hot tub?

The discs are each about 5 ft (1.5 m) across, so you can arrange several to cover larger or nonstandard shapes. They’re ideal for small round pools, spas and for supplementing coverage on larger above-ground pools. Measure your pool surface and plan coverage to ensure at least four-fifths surface coverage for best performance.

• Nine 5 ft discs per pack to configure around curves or gaps
• Suitable for above-ground pools, hot tubs, circular and irregular pools
• Easily trimmed or rearranged to adapt to varying pool sizes
• Simple floatable design requires no fittings or anchors

How do I use and maintain the solar pool covers?

Place the covers with the bubble (textured) side facing down onto the water; they will float and spread across the surface. Remove debris periodically and stack the covers out of direct sunlight when not in use to extend their lifespan. Clean with mild soap and water if needed and avoid sharp objects when handling.

• Bubble side down for correct floating orientation
• Stack indoors or shaded area to reduce UV wear when off-season
• Wipe with mild detergent to remove stains or algae buildup
• Inspect edges for tears and replace individual discs as needed

What are the main advantages of choosing this 9-piece set?

Buying nine separate discs gives flexibility for covering unusual pool layouts and allows partial coverage when full coverage is impractical. The thicker 16 mil construction improves durability versus thinner single-layer options and helps protect the water from large debris while lowering evaporation.

• Modular approach fits more pool shapes and sizes
• Pack of nine reduces need to purchase custom-sized covers
• Helps minimize debris entry, simplifying pool maintenance
• Cost-effective compared with oversized single-sheet covers

Who is this for: The Wesiti 5 ft 16 mil Solar Pool Cover 9-pack suits owners of above-ground pools, small circular pools, hot tubs and spas who want a modular, durable way to reduce heat loss and evaporation without permanent installation. It’s a practical option for renters, seasonal pool users and anyone with irregular pool shapes who prefers a flexible, repositionable heating accessory.
