Smart Heat Retention Technology
Engineered for maximum thermal efficiency and water conservation
How It Works
The solar blanket harnesses passive solar energy during daylight hours, transferring heat directly to your pool water. The 300μm LDPE material acts as an insulating barrier, reducing nighttime heat loss by up to 40% compared to uncovered pools.
Energy Savings Calculator
Average pool owners save 35-55% on heating costs annually. For a 20'x40' pool, this translates to roughly 300− 300−600 per year in reduced energy bills.
