Safety covers serve double duty as winter covers in cold climates, eliminating the need for separate seasonal covers. Their superior strength and durability justify the higher investment for families with young children or pets.

Solar Covers: Heat Retention and Energy Savings

Solar covers (also called solar blankets or bubble covers) float directly on the water surface, using thousands of air-filled bubbles to trap heat and reduce evaporation. These covers are essential for heated pools and extend swimming seasons in cooler climates.

How Solar Covers Work:

The bubble side faces down, creating insulating air pockets that trap heat. The top surface absorbs solar radiation, transferring warmth to the water below. This dual action can raise water temperature by 10-15°F and reduce heating costs by 50-70%.

The Round Swimming Pool Solar Cover Protector offers excellent heat retention for round pools up to 15 feet in diameter.

Solar Cover Benefits:

• Temperature Increase: Passive solar heating adds 10-15°F to water temperature
• Evaporation Prevention: Reduces water loss by 95%, saving thousands of gallons
• Chemical Conservation: Blocks UV rays that break down chlorine and other chemicals
• Debris Protection: Keeps leaves, insects, and dirt out of water
• Extended Season: Allows swimming 2-4 weeks earlier in spring and later in fall

Color and Thickness Options:

• Clear/Transparent: Maximum solar gain, best for heating, shows debris easily
• Blue: Balanced heating and aesthetics, most popular choice
• Dark Blue/Black: Maximum heat absorption, best for cold climates
• Silver/Light: Reflects heat, used in hot climates to prevent overheating

Thickness ranges from 8-16 mil, with thicker covers lasting longer but costing more. A 12-mil cover offers the best balance of durability and cost for most residential pools.

Solar Cover Limitations:

• Not designed for safety cannot support weight
• Requires daily removal for swimming
• Cumbersome to handle on large pools without reel system
• Lifespan of 3-5 years before UV degradation requires replacement
• Must be removed during chemical shocking
