Buying guide

What to look for

Assessing Material Thickness

Material thickness is measured in mils, with higher numbers generally indicating a more durable cover. For an 18x36 pool, a 12mil cover provides a solid balance of weight and insulation, while a 16mil cover offers superior longevity and heat retention. Consider your local climate and how often you plan to remove the cover when choosing the right thickness. Thicker covers are heavier and may require a reel system for easy operation, whereas thinner covers are more lightweight but may be more susceptible to tears over time. Evaluate your personal capacity for handling the weight of the cover to ensure you choose a product that you can comfortably manage on a daily basis throughout the swimming season.

Confirming Pool Dimensions

While 18x36 is a standard size, always measure your pool’s actual water surface area before purchasing. Some covers are designed to be trimmed to fit specific shapes, while others are sold as exact rectangles. Ensure the cover you choose provides full coverage to maximize heat retention and minimize evaporation. If your pool has unique features like stairs, a tanning ledge, or a spa spillover, you may need to purchase a larger size to allow for custom trimming. Always verify the manufacturer’s guidelines regarding trimming and fit to ensure you do not void any potential warranties or compromise the effectiveness of the cover’s insulation properties.

Evaluating Heat Retention Needs

Consider the primary purpose of your solar blanket. If you live in a region with cool nights, prioritize models with higher insulation ratings or those that come with supplementary products like liquid heat shields. The goal is to trap the heat absorbed during the day and prevent it from escaping at night. Look for features like bubble density and material quality, as these directly influence how effectively the cover performs. If your main goal is simply to reduce evaporation, a standard-thickness cover might suffice. Assess your regional temperature fluctuations and your desired pool water temperature to determine the level of thermal protection required for your specific inground pool setup.

Considering Ease of Use

A solar blanket is only effective if you use it consistently. Consider the physical effort required to put the cover on and take it off your 18x36 pool. A reel system is highly recommended for covers of this size, as it makes the process much faster and easier. If you do not have a reel, look for lighter-weight materials that are easier to fold and store. Consider the layout of your pool deck and whether there is adequate space to store the cover when it is not in use. Choosing a product that fits your daily routine will ensure you actually use the cover, maximizing the heating and chemical savings benefits.

Reviewing Material Durability

The longevity of a solar blanket is influenced by its resistance to UV rays and chemical exposure. Look for covers that are treated with UV inhibitors to prevent premature breakdown from sun exposure. Consider the quality of the bubble construction, as this is often the first part of the cover to fail. Read through product descriptions for mentions of heavy-duty materials or reinforced seams. While all pool covers will eventually degrade, choosing a model designed for durability will save you money in the long run by reducing the frequency of replacements. Assess your expectations for how long you want the cover to last and balance that against your budget and the intensity of your local weather conditions.

Understanding Warranty Terms

Always check for warranty information provided by the manufacturer. Warranties for solar blankets often cover defects in material or workmanship, but they rarely cover damage caused by improper handling, chemical imbalance, or environmental factors. Understand what is specifically covered and for how long. Some manufacturers offer prorated warranties, which may be useful if the product fails prematurely. Keep your purchase records and any documentation provided with the product. If you have questions about the warranty, contact the manufacturer directly before purchasing to ensure you have a clear understanding of your coverage. Knowing the warranty terms provides peace of mind and helps you protect your investment throughout the life of the product.

Checking Compatibility and Add-ons

Some solar blankets are part of a larger system or bundle, such as those including liquid heat shields or storage bags. Consider whether these add-ons provide value for your specific needs. If you already have a reel system, ensure the cover you choose is compatible with your existing hardware. If you are starting from scratch, look for bundles that include everything you need for a complete setup. Evaluate whether the additional cost of a bundle is justified by the included components. Always verify the compatibility of any accessories with your pool type, whether it is in-ground or above-ground, to ensure a proper and safe installation that meets your requirements.

Ownership guide

Setup, use, and maintenance

Routine Surface Cleaning

Regularly remove debris like leaves, twigs, and dirt from the top of your solar blanket to prevent organic matter from decaying on the surface. Use a soft brush or a gentle spray from a garden hose to clear the cover before folding or rolling it. Keeping the surface clean ensures maximum sunlight penetration, which is vital for effective heating. Avoid using harsh chemicals or abrasive tools that could damage the bubble structure.

Proper Storage Techniques

When the pool is in use, store your solar blanket in a shaded area to prevent UV degradation. Avoid leaving the cover bunched up on the pool deck in direct sunlight, as this can cause the material to break down prematurely. Using a reel system is highly recommended for 18x36 covers, as it keeps the material neatly stored and protected from foot traffic. If a reel is not available, fold the cover carefully rather than dragging it across rough surfaces.

Chemical Balance Monitoring

Solar blankets can impact your pool chemistry by reducing evaporation and trapping heat. Because less water is lost, you may find that your chemical concentrations change differently than when the pool is uncovered. Test your water frequently to ensure that pH, alkalinity, and sanitizer levels remain within the recommended ranges provided by your pool chemical manufacturer. High levels of chlorine can accelerate the breakdown of the plastic material in your cover, so ensure your sanitizer levels are properly balanced. Never add concentrated chemicals directly onto the cover. If you must shock the pool, remove the cover entirely and wait for the chemicals to circulate and stabilize before replacing it to prevent damage to the blanket’s surface and longevity.

Inspecting Material Integrity

Periodically inspect your solar blanket for signs of wear, such as thinning material, torn seams, or collapsed bubbles. Check the edges of the 18x36 cover for fraying, which often occurs due to friction against the pool coping. If you notice significant damage, it may be time to consider a replacement to maintain heat retention efficiency. Small tears can sometimes be repaired with specialized pool cover tape, but extensive damage usually warrants a new purchase.

Winterization and Long-term Care

At the end of the season, thoroughly clean and dry your solar blanket before storing it for the winter. Ensure all water is drained from the bubbles to prevent freezing, which could cause the material to crack. Store the cover in a cool, dry, and dark location, such as a garage or shed, to protect it from harsh winter elements and pests. If the cover is too large, consider using a protective storage bag designed for pool covers.

FAQ

Pool Maintenance — FAQ

How do I know if a solar blanket will fit my 18x36 pool?

Most solar blankets for 18x36 pools are designed to be slightly larger or exactly sized for that footprint. If you have a custom shape or stairs, look for a cover that can be trimmed with heavy-duty scissors. Always measure the actual water surface area of your pool before purchasing. If the cover is too small, it will not effectively retain heat or prevent evaporation. If it is too large, you will need to trim it carefully according to the manufacturer’s instructions. Always verify the dimensions listed on the product page to ensure it matches your specific pool requirements.

Can I use a solar blanket on an above-ground pool?

Yes, many solar blankets are designed to be versatile and can be used on both in-ground and above-ground pools. However, you should always check the product title and description to ensure it is rated for your specific pool type. Above-ground pools may have different coping or deck configurations that could affect how the cover sits on the water. If the product specifies it is for in-ground use only, it is best to stick to that recommendation to ensure the cover performs as expected and fits your pool safely and securely.

How much heat will a solar blanket actually add to my pool?

A solar blanket works primarily by retaining the heat already in the pool and reducing heat loss through evaporation. While it can help raise the water temperature by several degrees depending on the amount of sunlight and local air temperature, it is not a replacement for a dedicated pool heater. The effectiveness of the cover depends on the quality of the material, the thickness of the bubbles, and how consistently you keep the pool covered. It is best viewed as a passive heating tool that maximizes the sun's natural energy to keep your pool comfortable for swimming.

Is a thicker solar blanket always better?

Not necessarily. While a thicker blanket, such as a 16mil model, offers increased durability and insulation, it is also heavier and more difficult to handle. If you do not have a reel system, a 16mil cover might be too cumbersome to remove and replace daily, leading you to use it less often. A 12mil cover provides a good balance of durability and ease of use for many pool owners. Consider your physical ability to manage the cover and whether you have a reel system before deciding on the thickness that is right for you.

Do I need to remove the cover when I add pool chemicals?

Yes, it is highly recommended to remove the solar blanket before adding any chemicals to your pool. Concentrated chemicals can damage the material of the cover, causing it to break down, fade, or lose its effectiveness. After adding chemicals, wait for them to circulate and stabilize according to the chemical manufacturer’s instructions before replacing the cover. This practice protects your investment and ensures that your pool water remains balanced and safe for swimmers, while also preventing unnecessary wear and tear on the blanket’s surface and bubble structure over time.

How long should a solar blanket last?

The lifespan of a solar blanket typically ranges from two to five years, depending on the quality of the material, how well it is maintained, and the climate. Covers that are exposed to high levels of UV radiation and intense heat will naturally degrade faster than those in milder climates. Proper storage during the off-season, regular cleaning, and maintaining proper pool chemistry are the most effective ways to extend the life of your cover. If you notice the material becoming brittle or the bubbles collapsing, it is likely time to replace the cover to maintain its insulation properties.

Can I use a solar blanket with a salt water pool?

Yes, you can use a solar blanket with a salt water pool. However, it is important to keep your salt and sanitizer levels within the recommended range, as excessive salt or chlorine can potentially accelerate the degradation of the plastic material. Always monitor your pool chemistry regularly and ensure that your salt water generator is properly calibrated. If you notice any signs of premature wear, rinse the cover with fresh water to remove any salt residue, and ensure it is kept clean. Following these simple steps will help you maintain the integrity of your cover in a salt water environment.

What is the best way to clean a solar blanket?

The best way to clean a solar blanket is to use a soft brush and a gentle spray from a garden hose. Avoid using abrasive scrubbers or harsh chemical cleaners, as these can damage the bubbles and the material. If there is stubborn dirt or algae, a mild soap solution can be used, followed by a thorough rinse with fresh water. Always ensure the cover is completely dry before folding or rolling it for storage to prevent the growth of mold or mildew. Regular, gentle cleaning is sufficient to keep your blanket in good condition throughout the season.
