Blue 20 ft x 40 ft Rectangle Pool Solar Cover - Heat Retaining Blanket

In this review of the Blue 20 ft x 40 ft Rectangle Pool Solar Cover readers will find whether this 1200 Series blanket is right for their rectangular inground or above ground pool. The bottom line: it is a strong value purchase for pool owners who want an easy way to raise and maintain water temperature using free sunlight while cutting evaporation and debris. The cover's biggest selling point is simple: it traps solar heat to raise water temperature by up to 15 Degrees and hold warmth after sunset, which is the primary reason many buyers will choose it.

Key Features

• Free Solar Energy: Uses direct sunlight to raise pool water temperature by up to 15 Degrees, reducing the need for supplemental heating.
• Heat Retention: The material holds warmth long after sunset so overnight temperatures stay more consistent.
• Evaporation Reduction: Cuts evaporation by up to 95%, which helps conserve water and reduce chemical replacement frequency.
• Debris Prevention: Stops leaves and larger debris from entering the pool, reducing cleaning time and strain on filters.
• Durable Fit: Designed with extra overlap and six heavy-duty grommets for straightforward installation and anchoring around typical pool protrusions.

Who It's For

This solar cover is best for homeowners with rectangular inground or above ground pools who want a low-cost, low-effort way to raise water temperature and reduce maintenance. It particularly suits seasonal pools where a 10-15 Degree boost makes spring and fall swimming more comfortable and can offset fuel costs for auxiliary heaters.

Pool owners looking for a permanent, heavy-duty winter cover or who need a perfect professional-grade seam warranty should look elsewhere; some customers report mixed experiences with long-term durability at seams and with bubble size, so if heavy daily handling or very long service life is critical, consider reinforced commercial options.

Pros & Cons

Pros

• Effective at warming water and retaining heat into the evening, improving swim comfort.

Cons

• Durability can be variable; some customers report seam failure over time under heavy use.
• Bubble size and material thickness may not match higher-end solar blankets for longevity.
