Tracy’s Tips: Bubble Solar Cover Installation

Solar Pool Covers: Bubble Side Up or Down?  

Are you using a bubble solar cover to keep your pool water warm? If so, you may be wondering which side of your bubble cover should face up. We recommend covering your pool with the bubble side facing down for the best results in warming your pool in the summer sun. The sun’s UV rays will heat the bubbles and in turn, transfer heat to your pool water. With the bubbles facing down directly into the water, the heating process works more quickly and the bubbles help the cover float on the water’s surface.

Applying your bubble solar cover with the bubbles facing up can eventually damage the bubbles on the cover, due to direct exposure to the sun. The sun’s rays need to be able to flow through the cover before it can reach the water. Think of your solar cover as a thermal blanket or magnifying glass for your pool, intensifying the warming effect. Putting the cover on with the bubbles upward will take longer to heat your pool water and shorten the useful life of the cover.
