HPI Rectangular Solar Blankets: Extend Your Swim Season

Keep your pool warmer, longer. HPI Solar Blankets act as a powerful, passive heating system for your in-ground pool. By creating a thermal barrier between the water surface and the air, these blankets significantly reduce heat loss through evaporation—the primary cause of cooling in outdoor pools. These covers are designed to trap the sun’s UV rays, effectively warming your pool water by up to 10°F (5°C) to 15°F (8°C) over the course of a season.

Beyond heating, these covers offer excellent protection against contaminants. By keeping leaves, dirt, and debris out of your water, they help maintain water balance, reduce your daily sanitizer demand, and save you valuable time on manual cleaning.

Key Features & Innovations

• Evaporation Control: Acts as a liquid insulator, preventing heat loss caused by overnight evaporation and cooling breezes.

• Passive Solar Heating: The specialized translucent material allows UV rays to penetrate and heat the water beneath.

• Chemical Savings: By reducing evaporation, you lose fewer water-treatment chemicals, saving money on daily maintenance costs.

• Debris Protection: Physically blocks leaves, bugs, and wind-blown dust from entering the water.

• Durability: Built with high-quality, UV-resistant materials designed to provide reliable performance in the Canadian climate.

Shipping & Handling Notes

• Material: High-grade polyethylene bubble-cell technology.

• Storage Recommendation: To maximize the lifespan of your blanket, always cover it with a protective white solar cover sheet when stored on a reel in direct sunlight.

• Custom Fitting: If your pool dimensions are slightly different, these blankets can be easily trimmed with heavy-duty household scissors to fit your pool perfectly.
