Installing Pool Cover: Solar Pool Covers Bubbles Up Or Down

The best solar pool cover on the market doesn’t just keep dirt and debris out of your pool; it also heats the water. It collects the heat from the sun rays and takes it into your swimming pool to warm the water.

Does it make any difference to install the cover bubbles facing up or down? First, note that you should always install your pool cover bubbles facing down. Some people will argue that it’s better to have a cover with bubbles facing up than having no cover at all.

Bubbles Facing Up

If you install your cover with its bubbles facing up, the process of warming your pool will take longer and the sun might even destroy the bubbles. The reason behind this is that the bubbles are not facing your pool’s water directly.

They can easily overheat from the sun’s rays since they don’t have a place to take the trapped heat. This also means that the heat needs to travel through a third layer, the cover before it reaches the water.

To ensure that you cover lasts longer, always cover it with a sheet that reflects the rays when not in use or put it in a place with a shade like a shed or a garage. These gears retain a lot of heat and if not transferred to the water, they can easily “bake” themselves and reduce their life.
