SunHeater Pool Solar Blanket for Inground Pools
This SunHeater Pool Solar Blanket heats your pool naturally by trapping the sun’s warmth with its durable 12 mil thick polyethylene material. The thermal bubbles face downward to efficiently transfer heat into your pool water. It also minimizes evaporation by up to 95%, helping conserve water and maintaining chemical balance. Additionally, it lowers cleaning efforts by acting as a barrier against debris like leaves and dirt, making pool maintenance easier.
Blue Wave 12-Mil Solar Pool Blanket for Heat Retention
The Blue Wave Solar Blanket extends your swimming season by naturally heating the water up to 15°F using the sun’s energy. This 12-mil solar cover not only retains heat but also prevents about 95% of water evaporation, which reduces pool refills and chemical costs. Its durable design acts as a shield against insects and debris, ensuring clearer water and less frequent cleaning.
BigXwell 16-Mil Solar Pool Cover with Thermal Bubbles
The BigXwell Solar Pool Cover is made with 16 mil thickness, featuring thousands of thermal bubbles to maximize heat absorption and retention. It effectively heats your pool during sunny days and keeps water warm on cloudy or cool nights. Flexible and durable, it can be trimmed to fit any pool shape, compatible with both inground and above-ground pools.
SpaChoice Premium Liquid Pool Heater Solar Cover
Unlike traditional solar blankets, this SpaChoice Liquid Solar Cover comes in a convenient bottle that releases a thin, invisible layer on the water surface to reduce heat loss and evaporation. Recommended at 4 ounces per 15,000 gallons biweekly, it’s easy to apply and works in tandem with your pool’s filtration system to conserve heat without interfering with swimming comfort.
Abimars 16 Mil Solar Pool Cover with UV and Chemical Resistance
This Abimars Solar Pool Cover uses thicker 16 mil polyethylene with UV and chlorine resistance, providing long-lasting durability and protection against sun damage and chemical breakdown. Its densely packed bubbles absorb sunlight, raising water temperature by 8–15°F. The sturdy material and anti-curl edges help extend the swimming season while maintaining pool warmth efficiently.
Buying Guide for Solar Heaters for Inground Pools
Material Thickness and Durability
Solar pool covers typically range from 12 mil to 16 mil thickness. Thicker materials provide better insulation, heat retention, and longer lifespan but may cost more. Look for UV and chlorine resistant materials to prevent fading and damage.
Heat Absorption and Retention
Thermal bubble design greatly impacts heat transfer efficiency. Dense, large bubbles act as mini solar panels, capturing heat effectively. Covers that raise water temperature by 8–15°F extend swimming seasons and reduce the need for additional heating.
Size and Fit
Accurate sizing is essential for maximum coverage and effectiveness. Some covers like BigXwell’s are customizable via trimming. Consider your pool’s exact dimensions and shape for proper coverage to avoid heat loss.
Evaporation and Chemical Conservation
A good solar heater minimizes evaporation up to 95%, helping maintain chemical balance and saving water. This reduces refill frequency and chemical usage, lowering maintenance costs.
Pool Maintenance Benefits
Solar cushions also act as a debris barrier, preventing leaves and dirt from entering the pool. This reduces skimming and cleaning efforts, saving time and cleaning products.
Alternative Options: Liquid Solar Covers
For those looking for a low-maintenance option, liquid solar covers like SpaChoice’s formulation create an invisible insulating layer atop the water to reduce heat loss and evaporation without a physical cover.
Environmental Considerations
Solar pool heaters use renewable solar energy, lowering carbon footprints compared to electric or gas heaters, plus they save on energy bills.
