Buying guide

What to look for

Assessing Pool Dimensions

Before purchasing a swimming pool thermal cover, accurately measure your pool's length and width. Because these covers are often sold in standard sizes, you may need to trim the material to fit your specific pool shape perfectly. Use heavy-duty scissors to cut the cover once it is laid flat on the water surface, allowing for a slight overlap at the edges. Ensure your measurements account for any steps, ladders, or unique architectural features that might require custom trimming. Avoid buying a cover that is too small, as gaps around the edges will significantly reduce the efficiency of heat retention and evaporation control. Always verify the manufacturer's suggested trimming instructions before making your first cut to ensure the material remains stable and does not fray.

Understanding Material Thickness

Thickness, measured in mils, is a primary indicator of a cover's durability and thermal retention capabilities. A 12-mil cover is generally easier to handle and provides a good balance of performance for most residential pools. However, if you are looking for increased longevity and superior heat retention, a 16-mil cover is often preferred due to its heavier, more robust construction. Consider your local climate and how often you intend to remove and replace the cover. Thicker materials are more resistant to punctures and wear but can be heavier to manage. Evaluate your ability to handle the weight of the cover, especially if you do not plan to use a mechanical reel system to assist with daily operations.

Evaluating Bubble Technology

The bubbles in a solar cover act as insulators, trapping heat and preventing evaporation. When comparing products, look for high-quality bubble designs that are resistant to popping under pressure. The density and shape of the bubbles contribute to the cover's overall efficiency. While most blue covers function similarly, some designs incorporate black or opaque layers to improve heat absorption and light blocking, which can help inhibit algae growth. Research the specific bubble technology mentioned in the product description to understand if it aligns with your goals for heat retention versus light exclusion. A well-constructed bubble layer is the heart of your thermal cover, so prioritize options that emphasize durable, long-lasting materials that maintain their shape under the weight of water.

Checking Compatibility Needs

Verify that the cover you select is compatible with your pool's filtration and heating systems. Some covers may restrict water flow or interfere with skimmer operation if not properly fitted. If you use an automatic pool cleaner, ensure that the cover can be easily removed or that your cleaner is designed to operate beneath a cover. Check the manufacturer's specifications regarding chemical compatibility, as some covers are designed to withstand higher levels of pool sanitizers better than others. If you have specific pool accessories like fountains or water features, consider how the cover will fit around these elements. A proper fit is essential for safety and performance, so take the time to review all installation requirements before finalizing your purchase.

Reel System Considerations

While many solar covers can be operated manually, using a reel system significantly simplifies the process of covering and uncovering your pool. If you choose a thicker 16-mil cover, the added weight may make a reel almost essential for daily use. Check if the cover you are considering is compatible with standard pool cover reels. Some covers come with pre-attached straps or grommets that make connecting them to a reel system easier. If you plan to use a reel, ensure the cover's width matches the reel's capacity. Investing in a quality reel can save you significant time and effort, ensuring that you actually use the cover consistently, which is the only way to realize the promised thermal benefits.

Climate and Seasonal Use

Consider your local climate when selecting a thermal cover. If you live in an area with high wind or extreme temperature fluctuations, a heavier 16-mil cover will provide better stability and heat retention. Conversely, in milder climates, a 12-mil cover may offer sufficient performance. Think about the length of your swimming season and how much heat loss you typically experience. If your goal is to extend the season into cooler months, prioritize covers with superior thermal insulation properties. Also, consider UV exposure in your region; high-quality covers should have UV-resistant coatings to prevent the plastic from breaking down under the sun. Matching the cover's specifications to your specific environmental conditions is key to achieving the best possible results.

Warranty and Support

Always review the warranty information provided by the manufacturer before buying. A reputable company will stand behind the durability of their materials, offering coverage against defects in manufacturing or premature material failure. Pay close attention to what the warranty covers—such as seam failures or bubble delamination—and what it excludes, like damage from improper handling or chemical misuse. Check if the manufacturer provides clear installation guides or customer support channels for troubleshooting. A solid warranty is a good indicator of product quality and can provide peace of mind for your investment. If warranty details are unclear in the listing, reach out to the seller or manufacturer directly to clarify their policies before committing to a purchase.

Ownership guide

Setup, use, and maintenance

Regular Surface Cleaning

To maintain the efficiency of your swimming pool thermal cover, perform a weekly rinse using a gentle hose spray. This removes debris, leaves, and dust that can block solar rays and degrade the material over time. Avoid using abrasive brushes or harsh chemical cleaners, as these can damage the bubble structure and reduce the lifespan of the polyethylene material. If stubborn residue appears, use only mild, pool-safe soap and a soft sponge. Always ensure the cover is completely dry before folding it for storage to prevent mold or mildew growth.

Safe Removal Techniques

When removing your thermal cover, use a pool cover reel whenever possible to prevent unnecessary stress or tearing. If you must remove it manually, do so with a partner to avoid dragging the material against rough pool coping or sharp edges, which can cause significant damage. Fold the cover gently rather than bunching it up, as sharp creases can weaken the plastic bubbles over time. Always ensure that the cover is not snagged on ladder rails or filtration equipment before pulling.

Proper Storage Methods

Proper storage is critical for protecting your thermal cover during the off-season or when the pool is in frequent use. Never leave the cover exposed to direct, intense sunlight while it is off the pool, as this can cause the material to become brittle and degrade rapidly. Store the cover in a cool, shaded area, ideally covered by a protective tarp. If using a reel system, keep the cover shaded or use a protective cover sleeve to shield it from UV exposure.

Chemical Balance Monitoring

Using a thermal cover can significantly alter your pool's chemical balance by reducing evaporation and trapping heat. Because less water evaporates, you may find that chemicals become more concentrated over time. It is essential to test your water chemistry more frequently while using a cover to ensure that pH, alkalinity, and sanitizer levels remain within the recommended range. Never add concentrated chemicals directly under the cover; always remove the blanket and allow the chemicals to circulate fully before replacing it.

Inspection and Repair

Perform a monthly visual inspection of your thermal cover to identify signs of wear, such as thinning material, brittle spots, or popped bubbles. Check the seams and edges for fraying, as these are the most common points of failure. If you detect small holes or tears, use a manufacturer-approved patch kit to seal the area promptly. Preventing small issues from becoming large rips is the best way to extend the life of your cover.

FAQ

Pool Maintenance — FAQ

Will a solar cover really heat my pool?

A solar cover works by trapping heat from the sun and preventing it from escaping through evaporation. While it does not generate heat like a gas or electric heater, it acts as a highly effective insulator. By reducing heat loss during the night and keeping the water warmer during the day, it can significantly raise the average temperature of your pool. The exact temperature increase depends on your local climate, the amount of direct sunlight your pool receives, and how consistently you keep the cover on. Most users find it is a cost-effective way to maintain comfortable swimming temperatures throughout the season.

How do I trim the cover to fit my pool?

Most solar covers are designed to be trimmed to fit your specific pool shape. Once you have placed the cover on the water, use a pair of heavy-duty scissors to cut the material along the edge of the pool. It is often recommended to leave a slight overlap or cut it slightly larger than the pool edge initially, as the material may shift or settle.

Can I use a pool cleaner with the cover on?

Generally, it is not recommended to operate an automatic pool cleaner while the solar cover is in place. The cover can interfere with the cleaner's movement, and the cleaner itself might damage the underside of the cover. Most manufacturers suggest removing the cover before running your automatic cleaner. However, some pool owners find that they can use certain types of cleaners if they are specifically designed for use under a cover. Always check the manual for both your pool cleaner and your solar cover to determine compatibility and avoid potential damage to either piece of equipment or your pool surface.

How long should a solar cover last?

The lifespan of a solar cover typically ranges from one to three years, depending on the quality of the material, how well it is maintained, and your local climate. Factors like intense sun exposure, chemical balance in the pool, and how often the cover is handled contribute to its longevity. A 16-mil cover will generally last longer than a 12-mil cover due to its increased thickness and durability.

Does the cover help with pool chemicals?

Yes, a solar cover can help maintain your pool's chemical balance by significantly reducing evaporation. Since water evaporation is a primary cause of chemical loss, keeping the pool covered helps retain your sanitizer and other chemicals longer. However, because evaporation is reduced, you must monitor your chemical levels closely, as they can become concentrated. It is important to test your water regularly and adjust your chemical additions accordingly. Always remove the cover when adding chemicals to ensure they are properly distributed throughout the pool water and do not become trapped in high concentrations directly under the blanket, which could damage the cover material.

What is the difference between 12-mil and 16-mil covers?

The difference lies in the thickness of the material. A 12-mil cover is thinner, lighter, and generally easier to handle, making it a popular choice for smaller pools or for those who prefer a lightweight option. A 16-mil cover is thicker, more durable, and provides superior insulation and heat retention.

How do I clean the cover if it gets dirty?

Cleaning your solar cover is straightforward. Use a garden hose to gently spray off any leaves, dirt, or debris that may have collected on the surface. If there is stubborn grime, you can use a soft sponge and a mild, pool-safe soap. Avoid using high-pressure washers or harsh chemicals, as these can damage the delicate bubbles that provide the thermal insulation.

Do I need a reel for my solar cover?

While a reel is not strictly required, it is highly recommended, especially for larger pools or if you have a thicker 16-mil cover. A reel system makes it significantly easier to remove and replace the cover, which encourages daily use. Without a reel, the cover can be cumbersome to handle, increasing the risk of tearing or damaging the material.
