Buying guide

What to look for

Assess Your Pool Shape

Before purchasing, confirm that your pool is a standard 18-foot round shape. Solar blankets are typically sold in specific dimensions, and while some can be trimmed with scissors, it is best to start with a size that matches your pool's diameter perfectly. Check your pool's manual or measure the water surface area to ensure the cover will provide full coverage. A cover that is too small will allow excessive heat loss and evaporation, while one that is too large may be cumbersome to manage. Always verify the dimensions listed by the manufacturer against your pool's actual size to ensure a proper fit that maximizes heat retention and evaporation control for your specific setup.

Understand Material Thickness

Solar blanket thickness is measured in mils, with higher numbers generally indicating a more durable, heavy-duty product. A 10-mil cover is lightweight and easy to handle, making it a good choice for those who remove the cover frequently. Conversely, 12-mil or 16-mil covers offer superior durability and insulation, which can lead to better heat retention and a longer lifespan. Consider how often you intend to remove the cover and the typical weather conditions in your area. If you live in a region with high winds or harsh sun, a thicker material may be a better investment. Evaluate the trade-off between the ease of handling a lighter cover and the long-term robustness of a thicker, more heavy-duty option.

Evaluate Thermal Efficiency Needs

The primary purpose of a solar blanket is to heat the water and reduce evaporation. Look for features like bubble design and material composition that promote heat absorption. Thicker covers generally provide better insulation, keeping the water warmer for longer periods, especially overnight. If your goal is to extend your swimming season, prioritize models with high-rated thermal efficiency. Review the product descriptions to see if they emphasize heat-retaining properties. Keep in mind that while these covers are effective, their performance will vary based on the amount of direct sunlight your pool receives. Choose a cover that aligns with your specific climate and the desired temperature increase you hope to achieve for your swimming pool.

Check Compatibility with Accessories

Consider whether you plan to use a pool cover reel system. A reel makes it much easier to deploy and store your solar blanket, but you must ensure the cover is compatible with your specific reel model. Check if the cover comes with attachment kits or if you will need to purchase them separately. If you are using an existing reel, measure the width and ensure the new cover will fit comfortably. Some covers are better suited for manual handling, while others are reinforced to handle the tension of a reel system. Planning for these accessories before you buy can save you frustration and ensure a seamless setup process for your pool maintenance routine.

Review Material Quality Claims

Not all PE materials are created equal. Look for details regarding the quality of the solar blanket's construction, such as UV resistance and tear strength. A high-quality cover should be designed to withstand constant exposure to the sun's rays without becoming brittle or cracking prematurely. While you cannot physically test the material, read the provided product information for mentions of robust construction or specific material grades. Be wary of generic claims and look for evidence of durability in the manufacturer's description. Investing in a higher-quality material often pays off in the long run, as it will resist degradation and maintain its effectiveness for more seasons, ultimately providing better value for your money.

Consider Ease of Installation

Installation typically involves trimming the cover to fit your pool's exact shape. Check if the product includes instructions or if the material is designed to be easily cut with standard household shears. Some covers are pre-cut, while others require custom fitting. Think about your comfort level with DIY tasks. A cover that is easy to trim will save you time and ensure a clean, professional finish. If you have a complex pool shape, ensure the material is flexible enough to be shaped accordingly. Proper installation is key to the cover's performance, so choose a product that allows for a straightforward, manageable setup process that fits your skills and available tools.

Analyze Long-Term Ownership Costs

When evaluating the price, consider the total cost of ownership rather than just the initial purchase price. A cheaper, thinner cover might need to be replaced every season, while a more expensive, heavy-duty option could last for several years. Factor in the cost of potential repair kits and the time you will spend maintaining the cover. If you live in an area with harsh conditions, a more durable cover will likely be more cost-effective over time. Always weigh the upfront investment against the expected lifespan and performance benefits. By choosing a product that matches your usage patterns and environmental conditions, you can optimize your spending and ensure your pool remains well-maintained throughout the season.

By maintaining a balanced environment, you protect the structural integrity of the blanket, ensuring it remains flexible and effective at heat retention. Consult a professional pool service if you are unsure about appropriate chemical levels for your specific pool and cover combination.

Proper Seasonal Storage

When the swimming season ends, proper storage is critical to preventing damage. Thoroughly clean the cover with fresh water and allow it to dry completely before folding or rolling it. Moisture trapped in the folds can lead to mold or mildew growth. Store the cover in a cool, dry place away from direct sunlight, as prolonged UV exposure during the off-season can weaken the material. If you use a reel system, ensure the cover is neatly wound to prevent creases or tears.

Inspecting for Material Tears

Periodically inspect your solar blanket for signs of wear, such as small tears, punctures, or flattened bubbles. Early detection allows for minor repairs using specialized pool cover patch kits, which can prevent small issues from becoming large, irreparable rips. If you notice significant delamination or widespread bubble failure, it may be time to consider a replacement. Check the edges of the cover for fraying, as this is often where the first signs of stress appear. By catching these issues early, you maintain the cover's heat-retention efficiency and prevent loose plastic fragments from entering your pool's filtration system. Regular visual inspections are a simple but effective way to ensure your cover continues to perform its job throughout the entire season.

Gentle Handling During Removal

Always handle your solar blanket with care to avoid unnecessary tension or tearing. When removing the cover, fold or roll it slowly to prevent snagging on pool edges or ladders. If using a reel system, ensure it is properly aligned to avoid uneven stress on the material. Avoid dragging the cover across rough pool decks, as this can easily abrade the surface and damage the bubbles. If you are removing the cover manually, consider having a second person assist to distribute the weight evenly.
