Buying guide

What to look for

Understanding Material Thickness Mil

When selecting a swimming pool thermal blanket, the mil rating is a primary indicator of thickness and durability. A higher mil count generally suggests a thicker, more robust material that is more resistant to tearing and degradation from UV exposure. However, thicker blankets can also be heavier and more difficult to handle. Consider your ability to manage the weight of the cover when choosing between 12-mil and 16-mil options. Think about your local climate and how often you intend to remove and replace the cover.

Matching Size to Pool

Accurate measurement is essential when purchasing a swimming pool thermal blanket. You must measure the length and width of your pool surface to ensure full coverage. If your pool has a non-standard shape, you may need to purchase a larger rectangular cover and trim it to fit your specific dimensions. Check the manufacturer's instructions regarding trimming to ensure you do not void any warranties or compromise the edges of the cover. A properly fitted blanket should float freely on the surface without bunching up or leaving large gaps along the edges, which would allow for heat loss and evaporation. Always double-check your measurements before finalizing your purchase to avoid the inconvenience of returning or exchanging an incorrectly sized item.

Evaluating Heat Retention Needs

Consider your primary goal for using a swimming pool thermal blanket. If you are looking to extend your swimming season by a few weeks, a standard 12-mil cover may be sufficient. However, if you live in an area with significant nighttime temperature drops, a 16-mil cover with superior insulation properties may be a better investment. Think about the average ambient temperature in your region and how much heat loss you typically experience overnight. Some covers are specifically designed for enhanced solar absorption, while others focus more on insulation.

Assessing Reel System Compatibility

A reel system can significantly simplify the process of covering and uncovering your pool. Before buying a swimming pool thermal blanket, consider whether you plan to use a reel. If so, ensure that the cover you choose is compatible with standard reel attachments. Some covers come with pre-installed grommets or reinforcement kits that make them easier to secure to a reel. If you do not have a reel, think about how you will manually fold and store the blanket. A large, heavy cover without a reel can become a maintenance burden, potentially leading to less frequent use. Evaluate your setup and decide if investing in a reel system alongside your thermal blanket is necessary for your long-term satisfaction and ease of ownership.

Checking Material Durability Factors

Durability is a key factor in the value of a swimming pool thermal blanket. Look for materials that are UV-stabilized to prevent rapid breakdown from sun exposure. The quality of the PE material and the strength of the bubble construction are critical. While many products look similar, the manufacturing quality can vary significantly. Read through product descriptions to identify features like reinforced seams or high-density bubble designs that suggest a longer service life. Keep in mind that a cheaper, thinner cover might need to be replaced more frequently, potentially costing more over time than a higher-quality, more expensive option. Investing in a durable blanket often provides better long-term value, as it maintains its thermal performance and structural integrity for more seasons of use.

Reviewing Warranty and Support

While not always explicitly detailed in every listing, understanding the manufacturer's warranty and support policy is important. A reputable company should stand behind their swimming pool thermal blanket with a clear warranty that covers material defects. Check if the manufacturer provides clear instructions for installation, maintenance, and troubleshooting. If you have questions about the product, look for information on how to contact customer support. A company that offers robust support and a fair warranty period provides peace of mind, especially when purchasing a larger or more expensive cover. If warranty information is absent, consider reaching out to the seller directly to clarify what protections are included with your purchase before you make your final decision.

Considering Ease of Setup

The initial setup of a swimming pool thermal blanket should be relatively straightforward. Most covers are designed to be placed directly on the water surface. However, some may require trimming to fit, which can be a time-consuming task. Consider whether you have the necessary tools, such as heavy-duty scissors, to customize the cover if needed. Think about the weight of the material and whether you can handle the deployment process alone or if you need assistance. If you are opting for a heavy-duty 16-mil cover, be prepared for a more significant setup effort. Evaluating the setup process beforehand helps you prepare for the task and ensures that you can get your thermal blanket up and running efficiently without unnecessary frustration.

FAQ

Pool Maintenance — FAQ

How does a thermal blanket actually heat the pool?

A swimming pool thermal blanket works primarily through solar absorption and evaporation reduction. The material, often blue or black, absorbs solar energy and transfers that heat directly to the water surface. More importantly, the blanket acts as a physical barrier that prevents heat from escaping into the air, especially at night. By minimizing the cooling effects of evaporation, the blanket preserves the heat already present in the water, which is the most significant cause of pool temperature loss. It is a passive system that relies on consistent use to be effective.

Can I leave the blanket on while swimming?

It is generally recommended to remove the swimming pool thermal blanket completely before using the pool. Swimming with the cover on can be a safety hazard, as it may trap a person underneath the material or cause entanglement. Furthermore, the weight of a person on the blanket can damage the bubbles and the material itself. For safety and to protect the longevity of your cover, always fold or roll it away before entering the water. Using a reel system makes this process much faster and easier, encouraging safer and more frequent use.

How do I trim a cover to fit my pool?

Trimming a swimming pool thermal blanket is usually done with a pair of heavy-duty scissors. First, lay the cover on the pool surface and allow it to settle for a few hours. Once it is flat, mark the excess material along the edge of the pool. Use the scissors to cut carefully along your marks. It is often better to leave a little extra material initially, as you can always trim more later, but you cannot add material back. Always follow any specific instructions provided by the manufacturer to ensure you do not compromise the integrity of the blanket's edges.

Does the mil thickness really make a difference?

Yes, the mil thickness significantly impacts both durability and performance. A 16-mil blanket is thicker and generally more durable than a 12-mil version, making it more resistant to tears and punctures. It also provides slightly better insulation, which can be beneficial in cooler climates. However, the trade-off is increased weight and reduced flexibility, which can make the cover harder to handle. When choosing, consider whether you prioritize maximum durability and heat retention or ease of daily handling. Both thicknesses can be effective, provided the blanket is maintained and stored properly when not in use.

How often should I clean my pool blanket?

You should clean your swimming pool thermal blanket whenever you notice debris, leaves, or dirt accumulating on the surface. A simple rinse with a garden hose or a gentle scrub with a soft brush is usually sufficient. If left on the cover, organic matter can decompose and potentially damage the material or lead to mold growth. Regular cleaning also ensures that sunlight can penetrate the blanket effectively for better heat absorption. Aim to check the cover weekly, especially during seasons when trees are shedding leaves or debris is more common in your backyard area.

Will a thermal blanket keep the water clean?

While a swimming pool thermal blanket is primarily designed for heat retention, it also acts as a partial cover that keeps large debris like leaves and twigs out of the water. However, it is not a substitute for a dedicated pool cover or regular filtration and chemical maintenance. Small particles and dust can still get into the water, and the blanket does not prevent algae growth on its own. You will still need to run your pool filter and manage chemical levels to keep the water sanitary and clear, even when using a thermal blanket.

How do I store the blanket for the winter?

To store your swimming pool thermal blanket for the winter, first clean it thoroughly and ensure it is completely dry. Moisture trapped in the folds can lead to mold or mildew. Once dry, fold or roll the blanket carefully, avoiding sharp creases. Store it in a cool, dry, and shaded location, such as a garage or shed, away from direct sunlight and potential rodent damage. If you have a reel, you can often leave the cover on the reel, provided it is protected by a cover or stored in a sheltered area where it won't be damaged by freezing temperatures.

Are there any chemicals that damage these blankets?

High concentrations of chlorine or other pool sanitizers can cause the material of a swimming pool thermal blanket to degrade, become brittle, or lose its insulating properties over time. This is why it is crucial to remove the blanket during shock treatments and wait until chemical levels have stabilized before replacing it. Avoid using harsh cleaning agents or solvents on the blanket, as these can also cause damage. Always follow the manufacturer's guidelines regarding chemical exposure to ensure your blanket lasts as long as possible and continues to function effectively throughout the season.

Final verdict

Bottom Line

Choosing the right swimming pool thermal blanket depends on balancing your specific pool dimensions with your need for durability and ease of handling.
