Swimming pool heating costs can be significantly reduced by using a pool cover. Using a pool cover can help reduce the amount of chlorine and other chemicals required by the pool. Though a cover decreases the total amount of solar heat absorbed by the pool, the cover also eliminates heat loss due to evaporation and reduces heat loss at night.
Aqua Blue Custom Pools recommends and uses safety pool covers by LoopLoc and automatic pool covers by Aquamatic.
