Buying Guide: What to Consider When Choosing a Solar Blanket for Your Pool
Material Thickness
Solar blankets come in varying thicknesses measured in mils, generally ranging from 8 mil to 16+ mil. Thicker blankets offer better durability and heat retention but may be heavier and less flexible. For regular use, 10-12 mil is a good balance between performance and ease of handling. If you want added durability especially in harsh sun conditions, look for 15-16 mil blankets.
Shape and Size
Pool solar blankets are available in rectangular, round, and sometimes custom sizes to match your pool’s shape. Ensure you select a size that provides full coverage without excessive overlap or gaps, which can affect heating efficiency and evaporation reduction.
Heat Retention and Temperature Increase
Look for solar blankets that can increase water temperature by up to 15°F or more. Bubble design is critical in trapping solar heat and minimizing heat loss at night. Thermal bubbles also reduce wind chill on the water surface, enhancing heat retention.
Evaporation and Water Conservation
A quality solar blanket can reduce water evaporation by up to 95%, significantly saving water and reducing chemical consumption. This translates into less frequent refilling and lower maintenance costs, making it an eco-friendly choice.
Durability and UV Resistance
Exposure to sunlight, chlorine, and pool chemicals can degrade some materials quickly. UV-resistant and chemical-resistant solar blankets ensure longer lifespan without cracking, fading, or warping. Heavier material thickness usually correlates with improved durability.
Ease of Handling and Storage
Consider how easy it is to put on and remove the solar blanket. Some models come with reels to assist in covering and uncovering the pool effortlessly. The cover should be flexible enough to fold or roll up for storage when not in use.
Alternative Types: Liquid Solar Covers
If you prefer an invisible solution, liquid solar blankets like Lo-Chlor’s Aqua Blanket create a thin surface barrier to reduce evaporation and heat loss without the hassle of a physical cover. This option is suitable for those valuing convenience and minimal visual impact, though traditional blankets tend to offer superior insulation.
