Buying guide

What to look for

Assessing Your Pool Dimensions

Before purchasing a solar blanket, verify your pool dimensions with precision. While a 20x40 size is standard, variations in pool shape, radius corners, or built-in steps can affect how the cover fits. Measure the longest and widest points of your pool to ensure adequate coverage. If your pool has non-standard features, you may need to trim the blanket to fit. Always check the manufacturer's guidance on trimming, as improper cutting can void warranties or lead to fraying. Purchasing a cover that is slightly larger than your pool surface allows for necessary adjustments, ensuring that the entire water surface is covered for maximum thermal retention and evaporation control. Accuracy in measurement is the foundation of a successful solar blanket installation.

Understanding Mil Thickness Ratings

The 'mil' rating refers to the thickness of the solar blanket, with higher numbers generally indicating a more durable product. A 12-mil blanket is a common industry standard, offering a good balance between weight, handling, and heat retention. Thicker blankets are often more resistant to tears and can hold heat longer, but they are also heavier and more difficult to manage manually. Consider your ability to move and store the cover when choosing the thickness. If you have a reel system, a thicker blanket is often manageable. If you are handling the cover by hand, a lighter 12-mil option may be more practical. Always prioritize the trade-off between durability and ease of use based on your specific setup.

Evaluating Material Quality Claims

When comparing solar blankets, look for descriptions regarding UV stabilization and material quality. Solar covers are constantly exposed to harsh sunlight, which can break down low-quality plastics quickly. Look for products that explicitly mention UV-resistant materials or advanced polymer blends designed to withstand prolonged sun exposure. While all solar blankets are made of plastic, the quality of the raw material affects how long the bubbles remain intact and how flexible the blanket stays over time. Read product descriptions carefully for mentions of reinforced layers or specialized coatings that enhance longevity. Investing in higher-quality material can prevent the frustration of frequent replacements and ensure that the blanket remains a functional part of your pool maintenance routine.

Considering Reel System Compatibility

A solar cover reel is highly recommended for any 20x40 pool cover. These blankets are large and cumbersome to remove by hand. Before buying, check if your pool area has enough space to accommodate a reel system. A reel not only makes the process of covering and uncovering the pool significantly faster but also extends the life of the blanket by preventing unnecessary folding and dragging. Ensure the reel you choose is rated for the size and weight of your specific blanket. If you lack the space for a permanent reel, consider portable options or invest in a cover storage solution that keeps the material protected while not in use.

Reviewing Warranty and Support

Always check the warranty terms provided by the manufacturer. Solar blankets are subject to significant wear and tear, and warranty coverage can vary widely. Look for details on what is covered, such as material defects or premature degradation, and what is excluded, such as damage from improper storage or chemical misuse. A clear, comprehensive warranty can provide peace of mind. Additionally, check if the brand offers accessible customer support for questions regarding installation or maintenance. Knowing that you have a point of contact if something goes wrong is valuable. Keep your proof of purchase and any registration documents in a safe place, as these will be required should you need to file a claim.

Analyzing Buyer Feedback Patterns

When evaluating potential purchases, look beyond the star rating and read specific buyer feedback regarding durability and ease of use. Recurring complaints about bubbles popping, the material tearing, or difficulty in handling are important indicators of product performance. Conversely, positive feedback regarding heat retention and ease of installation can confirm your choice. Look for comments from owners with similar pool types to yours to see how the product performs in real-world scenarios. Pay attention to how the company responds to negative feedback, as this can indicate their commitment to customer satisfaction. Use these patterns as a guide to identify common pitfalls and select a product that aligns with your expectations for quality and performance.

Safety and Handling Precautions

Safety should be a priority when using any pool cover. Solar blankets are not safety covers and cannot support the weight of a person or pet. Never allow children or pets near the pool when the cover is partially or fully deployed, as they can easily become trapped underneath. Always ensure the cover is fully removed before anyone enters the pool. When handling the blanket, be mindful of the weight, especially when it is wet. Use proper lifting techniques to avoid injury. If you are removing the cover alone, use a reel system or ask for assistance. Prioritizing safety protocols ensures that your pool remains a fun and secure environment for everyone involved.

When the pool is in use, proper storage is essential to prevent damage. Avoid leaving the solar blanket bunched up on the pool deck, as direct sunlight on the folded material can cause extreme heat buildup, leading to melting or material fusion. Ideally, use a pool cover reel system to wind the blanket neatly. If a reel is not available, fold the blanket loosely and store it in a cool, shaded area away from direct UV exposure.

Inspection for Structural Integrity

Periodically inspect your solar blanket for signs of wear, such as thinning material, popped bubbles, or fraying edges. Small tears can often be repaired with specialized pool cover tape, but extensive damage may indicate it is time for a replacement. Check the perimeter of the blanket to ensure it is not catching on pool edges, coping, or skimmers, as these friction points can cause premature tearing.

Seasonal Removal and Winterization

At the end of the swimming season, thoroughly clean your solar blanket with a mild soap solution, rinse it well, and let it air dry completely in a shaded area. Once dry, fold or roll the blanket carefully to avoid creasing the material. Store it in a protective bag or a climate-controlled environment, such as a garage or shed, to protect it from freezing temperatures and heavy snow loads. Do not leave the solar blanket on the pool during the winter months, as it is not designed to withstand the weight of ice or heavy debris.

FAQ

Pool Maintenance — FAQ

Can I leave the solar blanket on the pool during a storm?

It is generally recommended to remove your solar blanket during severe storms or high winds. Strong winds can lift the blanket, potentially damaging it or blowing it onto your deck or into your landscaping. Additionally, heavy rain and debris can make the blanket difficult to manage and may lead to unwanted contaminants entering your pool water. If a storm is forecasted, use your reel system to wind the blanket up or fold it and store it in a secure, protected area. This simple precaution helps prevent accidental damage and keeps your cover in good condition for longer.

Does a solar blanket work in cloudy weather?

While solar blankets are most effective in direct sunlight, they still provide benefits during cloudy weather. The primary function of the blanket is to act as a thermal barrier, reducing heat loss through evaporation. Even without intense solar gain, the blanket helps maintain the heat already present in the water by preventing the cooling effect of wind and evaporation. While you may not see a significant temperature increase on a cloudy day, the blanket remains a valuable tool for preserving the heat you have already captured, ensuring your pool stays warmer than it would without any cover.

How do I know if my solar blanket is the right size?

A correctly sized solar blanket should cover the entire surface of the water, including the edges. If you have a rectangular pool, the blanket should fit flush against the pool walls. If you have a custom-shaped pool, you may need to trim the blanket to match the contours of your pool. When sizing, it is better to have a slightly larger cover that you can trim down rather than one that is too small. A gap between the cover and the pool edge allows heat to escape and water to evaporate, significantly reducing the efficiency of the blanket.

Can I use a solar blanket with a saltwater pool?

Yes, you can use a solar blanket with a saltwater pool. However, it is important to monitor your water chemistry regularly. Saltwater pools can sometimes be more demanding on equipment if the salt levels or pH are not properly balanced. Ensure that your salt chlorinator is functioning correctly and that your water balance remains within the recommended range. As with any pool, rinse the blanket periodically to remove any salt residue that may accumulate on the surface. Proper maintenance and regular water testing are key to ensuring both your pool equipment and your solar blanket last for many seasons.

How often should I clean my solar blanket?

The frequency of cleaning depends on your pool environment and how much debris typically lands in your pool. As a general rule, give the blanket a quick rinse with a garden hose whenever you notice a buildup of leaves, dirt, or other debris. For a more thorough cleaning, perform a gentle wash with a mild soap solution once or twice per season, or whenever the blanket appears dull or dirty. Keeping the surface clean is essential for allowing sunlight to penetrate and heat the water effectively. Regular, light maintenance is much easier than dealing with a heavily soiled or neglected solar blanket.

Will a solar blanket prevent algae growth?

A solar blanket is not designed to prevent algae growth; in fact, if not managed correctly, it can potentially create an environment where algae thrives. By trapping heat and preventing evaporation, the blanket creates a warm, still environment under the cover. If your pool's chemical balance is not maintained, algae can grow rapidly.

Can I walk on the solar blanket?

No, you should never walk on a solar blanket. Solar blankets are made of thin plastic material with air-filled bubbles and are not designed to support any weight. Walking on the cover can cause the bubbles to pop, the material to tear, and in the worst-case scenario, it can create a dangerous entrapment hazard. Always keep children, pets, and adults off the cover. Treat the solar blanket as a delicate piece of pool equipment and ensure that everyone using the pool understands that the cover is not a safety device and should never be stepped or sat upon.

How long does a typical solar blanket last?

The lifespan of a solar blanket varies depending on the quality of the material, the local climate, and how well it is maintained. On average, a well-cared-for solar blanket can last between two to five years. Factors that shorten its life include constant exposure to direct, intense UV rays, improper chemical balance in the pool, and lack of protection during the off-season. By following the manufacturer's maintenance guidelines, using a reel system, and storing the blanket properly when not in use, you can maximize its longevity and ensure you get the most value out of your investment over several swimming seasons.
