Its robust build quality handles the daily wear and tear of being placed on and off the pool surface, offering consistent protection and heat retention that outperforms thinner alternatives over the course of several swimming seasons.

What to look for

Verify Exact Pool Dimensions

Before purchasing, measure your pool surface area precisely. While 18x36 is a standard size, coping or unique pool shapes may require slight trimming. Ensure the cover you choose allows for this customization without voiding your warranty. Check the manufacturer's notes on whether the material is designed to be cut to size or if it must be ordered to exact specifications for your specific pool geometry.

Understand Material Thickness (Mil)

Thickness is measured in mils, where a higher number generally indicates a more durable and better-insulating cover. A 16mil cover is thicker and usually more resistant to wear than a 12mil option. Consider your local climate and how often you will be moving the cover; thicker material is heavier but offers better long-term heat retention and resistance to environmental stress over many seasons.

Evaluate Solar Heating Needs

Solar covers rely on sunlight to heat the water. If your pool is located in a heavily shaded area, the heating benefits may be limited. Assess the amount of direct sun your pool receives before opting for a premium solar blanket. If your primary goal is simply keeping debris out, a standard heavy-duty non-solar cover might be a more cost-effective and suitable choice.

Assess Ease of Handling

Consider the weight and physical effort required to deploy and remove the cover. A 16mil cover is significantly heavier than a 12mil version. If you do not have a pool cover reel, you may find a heavier cover difficult to manage alone. Think about your physical ability and whether you have assistance available to help with the daily routine of uncovering and covering your pool.

Check Compatibility and Fit

Confirm that the cover is specifically intended for your pool type, whether inground or above-ground. Some covers are designed with specific anchoring systems or material weights that perform differently depending on the pool structure. Review the listing details to ensure the cover's design matches your pool's edge or coping style, which is crucial for achieving a proper seal and preventing debris from entering the water.

Review Warranty and Support

Check the manufacturer's warranty terms for coverage details regarding material degradation or manufacturing defects. Understand what is excluded from the warranty, such as damage caused by improper chemical usage or wind. A longer warranty period often reflects the manufacturer's confidence in the material quality. Keep your receipt and purchase information in a safe place should you need to file a claim in the future.

Consider Long-Term Ownership Costs

Factor in the cost of accessories like cover reels, cleaning supplies, and potential replacement parts. A higher-priced, durable cover may have a lower total cost of ownership over five years compared to a cheap cover that must be replaced annually. Look at the balance between initial purchase price and the expected lifespan of the product to determine the best long-term value for your specific budget.

Setup, use, and maintenance

Regular Surface Cleaning

To maintain efficiency, periodically rinse the cover with a garden hose to remove debris, leaves, and dust. Avoid using abrasive brushes or harsh soaps that could damage the bubble material. Always allow the cover to air dry completely before folding or rolling it for storage to prevent mold or mildew growth. Keeping the surface clean ensures that sunlight can penetrate effectively for maximum solar heating.

Safe Chemical Management

Always follow the manufacturer guidelines regarding pool chemical levels when using a solar cover. High chlorine concentrations can degrade the material prematurely. Remove the cover during shock treatments to allow gases to dissipate, as trapped chemicals can damage the underside of the blanket. Consult your pool chemical supplier to ensure your water balance is compatible with your specific cover material to extend its lifespan.

Proper Folding Techniques

When removing the cover, use a reel system if possible to minimize folding and creasing. If manual removal is necessary, fold the cover carefully rather than bunching it up. Sharp creases can lead to cracks in the bubble material over time. Store the folded cover in a shaded area away from direct sunlight when not in use to prevent UV damage to the top surface.

Seasonal Inspection Routine

Inspect your cover every few weeks for signs of wear, such as thinning material, popped bubbles, or fraying edges. Early detection of small tears allows for simple repairs before they expand and compromise the entire cover. Ensure that the edges are not rubbing against rough coping or sharp pool deck surfaces, which can cause premature fraying and reduce the overall effectiveness of the thermal seal.

Off-Season Storage Best Practices

When the pool is not in use for an extended period, clean, dry, and securely store the cover in a cool, dry place. Avoid leaving it exposed to extreme winter temperatures or heavy snow loads if it is not specifically rated for such conditions. Protecting the material from environmental extremes during the off-season is the single most effective way to ensure it remains functional for the next year.
