Buying guide

What to look for

Measuring Your Pool Dimensions

Before purchasing, accurately measure the length and width of your rectangular pool. While these covers are listed for 20x40 pools, slight variations in pool shape or coping can affect the fit. It is better to have a slightly larger cover that can be trimmed to size than one that is too small. Verify your pool's actual dimensions versus the nominal size to ensure adequate coverage.

Understanding Material Thickness

Solar covers are often rated in mils, which indicates the thickness of the material. A 12-mil cover is a common industry standard, offering a balance between durability and ease of handling. Thicker materials may provide better insulation and longevity, but they are also heavier and harder to manage manually. Consider your ability to handle the cover when choosing the thickness that suits your needs.

Assessing Your Handling Capability

Consider how you intend to remove and replace the cover daily. A 20x40 cover is large and can be cumbersome to manage by hand. If you do not have a pool cover reel, you may find the process physically demanding. Assess whether you have the space and budget to add a reel system, which significantly simplifies the daily operation and storage of the cover.

Evaluating Local Climate Conditions

Think about your local climate and how much sun your pool receives. Solar covers rely on UV energy to heat the water. If your pool is heavily shaded, the heating benefits may be limited, though the cover will still serve as an effective evaporation barrier. Choose a cover that aligns with your primary goals, whether that is maximum heat gain or simple water conservation.

Checking Material Quality and Durability

Look for descriptions that emphasize heavy-duty construction or UV resistance. While all solar covers are made of plastic, the quality of the resin and the design of the bubbles can vary. Higher-quality materials are more resistant to the harsh environment of a pool, including exposure to direct sunlight and water treatment chemicals, leading to a longer overall product lifespan.

Reviewing Warranty and Support

Always check the listing for information regarding warranties or manufacturer support. While many solar covers have limited warranties, understanding the terms can provide peace of mind. If the listing lacks specific warranty details, contact the seller to clarify what is covered and for how long. Knowing the manufacturer's stance on defects can help you make a more informed purchasing decision.

Considering Long-Term Ownership Costs

Beyond the initial purchase price, consider the cost of potential accessories like reels or storage bags. Additionally, remember that solar covers are consumable items that will eventually need replacement due to UV degradation. Factor these recurring costs into your budget to ensure that a solar cover remains a cost-effective solution for your pool maintenance needs over the coming years.

Ownership guide

Setup, use, and maintenance

Regular Surface Cleaning Routine

To maintain your solar cover, gently hose off debris, leaves, and dirt from the top surface regularly. Allowing organic matter to decay on the cover can degrade the material and introduce unwanted contaminants into your pool water. Use a soft-bristled brush if necessary, but avoid harsh scrubbing that could damage the bubble structure. Always ensure the cover is rinsed thoroughly before removal to prevent transferring debris into the water. Keeping the surface clean helps maximize solar absorption and keeps your pool looking pristine throughout the season.

Safe Removal and Handling

When removing your 20x40 cover, avoid dragging it across abrasive pool decks or coping, as this can cause tears or punctures. If possible, use a pool cover reel system to roll the blanket evenly. If manual removal is necessary, fold the cover carefully rather than bunching it up. Always store the cover in a shaded area when not in use to prevent UV damage, which can weaken the plastic material over time. Proper handling significantly extends the lifespan of your investment and ensures the cover remains effective at trapping heat and reducing evaporation.

Chemical Balance and Compatibility

Be mindful of your pool chemistry when using a solar cover. High levels of chlorine or imbalanced pH can accelerate the degradation of the cover material. Always follow the manufacturer's guidelines regarding chemical exposure and ensure your pool water is properly balanced. Never add concentrated pool chemicals directly onto the cover. If you are shock-treating your pool, it is often recommended to remove the cover for several hours to allow chemicals to dissipate. Always consult your pool chemical labels and follow professional guidance to ensure the longevity of both your water quality and your solar blanket.

Seasonal Storage and Protection

At the end of the swimming season, clean the cover thoroughly with fresh water and allow it to dry completely before storage. Storing a wet or dirty cover can lead to mold and mildew growth. Once dry, fold or roll the cover neatly and store it in a cool, dry, and protected location away from direct sunlight and freezing temperatures. Using a protective cover or storage bag can further shield the material from pests or accidental damage during the off-season. Proper winterization is essential for ensuring your cover is ready for use when the next swimming season arrives.

Monitoring for Material Wear

Periodically inspect your solar cover for signs of wear, such as thinning material, brittle bubbles, or small tears. If you notice significant deterioration, it may be time to replace the cover to maintain its heat retention efficiency. Small tears can sometimes be repaired with dedicated pool cover patches, but extensive damage usually warrants a replacement. Keep an eye on the edges and seams, as these areas often experience the most stress. By proactively monitoring the condition of your cover, you can address minor issues before they become major problems, ensuring your pool remains protected and energy-efficient year-round.

FAQ

Pool Maintenance — FAQ

How do I trim a 20x40 solar cover to fit my pool?

Most solar covers are designed to be trimmed to fit your pool's specific shape. Lay the cover on the water surface and let it sit for a few hours to flatten out. Use a pair of heavy-duty scissors to trim the excess material along the edges, leaving a small overlap if desired. Ensure you follow the manufacturer's instructions, as improper trimming can lead to fraying or damage. Always take your time and measure twice before cutting to ensure a clean, accurate fit for your pool.

Will a solar cover really heat my pool?

A solar cover works primarily by trapping heat and preventing evaporation, which is the leading cause of heat loss in pools. By creating a thermal barrier, the cover helps retain the heat absorbed from the sun during the day. While it does not generate heat like a heater, it significantly reduces the rate at which your pool cools down, helping to maintain a more comfortable temperature throughout the swimming season, especially when used in conjunction with sunny weather conditions.

How long should a solar cover typically last?

The lifespan of a solar cover depends on several factors, including material thickness, exposure to UV rays, and how well it is maintained. Generally, a quality 12-mil cover can last between two to four seasons with proper care. Regularly cleaning the cover, storing it out of the sun when not in use, and keeping your pool chemistry balanced will help maximize its longevity. If the material becomes brittle or the bubbles begin to break, it is likely time for a replacement.

Should I leave the cover on during a storm?

It is generally recommended to remove your solar cover during severe storms or high winds. Strong winds can lift the cover, potentially damaging it or blowing it out of the pool. Additionally, debris from storms can settle on the cover, making it difficult to clean and potentially introducing contaminants into your water. If you expect heavy weather, take the time to remove and store the cover safely to prevent any accidental damage or loss of the material.

Can I use a solar cover with an automatic pool cleaner?

Yes, you can typically use a solar cover alongside an automatic pool cleaner. However, you must remove the cover to allow the cleaner to reach the entire pool surface, or use a cleaner designed to operate under a cover if applicable. Many pool owners prefer to run their cleaners at night or during times when the cover is off. Always ensure your cleaner is compatible with your pool type and follow the manufacturer's instructions for operation.

Is it necessary to use a reel system?

While a reel system is not strictly necessary, it is highly recommended for a 20x40 cover. A cover of this size is large, heavy, and difficult to handle manually. A reel system allows you to roll and unroll the cover with ease, which encourages daily use and protects the material from unnecessary wear and tear caused by dragging or folding. It is a worthwhile investment for the convenience and longevity of your solar cover.

What should I do if the bubbles on my cover start popping?

The bubbles on a solar cover are designed to trap air and provide insulation. Over time, exposure to UV rays and pool chemicals can cause these bubbles to degrade and pop. Once the bubbles start popping, the cover loses its insulating properties and efficiency. While small areas of damage might be manageable, widespread popping indicates that the cover has reached the end of its life and should be replaced to ensure continued heat retention performance.

Can I use a solar cover in the winter?

Solar covers are not intended for use as winter covers. They are designed to be used during the swimming season to retain heat and reduce evaporation. Using a solar cover during the winter can expose it to freezing temperatures and heavy debris, which will quickly damage the material. For winterizing your pool, you should use a dedicated winter cover designed to withstand the harsh conditions of the off-season and provide proper protection for your pool structure.
