What Are the Functions of a Solar Pool Cover?
Pools lose most of their heat--almost 90 percent--at the water's surface. Adding a cover can save pool owners money. Solar pool covers, also called "bubble covers," are an alternative to more costly and heavier vinyl and insulated vinyl pool covers. They use the sun's energy to retain water heat and cut down on energy costs. Does this Spark an idea?

Features
-
Solar pool covers are plastic sheets imprinted with a bubble pattern that resembles bubble-wrap packing material. They are made of heavier-grade plastic that is resistant to ultraviolet radiation.
Function
-
The bubbles absorb and hold the sun's heat to keep the pool water warm. The plastic sheet also reduces evaporation and keeps leaves, insects and other debris out of the water.
-
Effects
-
Heat retention means the pool's heater operates more efficiently and that efficiency cuts down on energy costs. A debris-free pool also helps owners save money on chemicals and cleaning.
Types
-
Solar pool covers can float freely on top of the water, be held down by anchors along poolside or be rolled up on a reel by hand or with a motor. Custom shapes and sizes are also available. They work on above- and in-ground pools.
Considerations
-
Solar pool covers may need to be replaced every three to five years due to deterioration from UV rays. Always place the pool cover bubble-side down.
