Solar Pool Covers Bubbles Up Or Down

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.

Depending on your area, this gear might not keep your facility as warm as an electricity or gas heater, but the cover saves you money by minimizing evaporation. With that said, there is one main question that all pool owners ask: to install solar pool covers bubbles up or down?

Bubbles Up or Bubbles Down

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.


Why do we say bubbles down? Before we look at the reason for installing your pool cover bubbles facing down, ensure that you get the best pool algaecide for green algae for your pool to ensure it is free of these algae.

Back to the cover! A pool cover works by the rays from the sun heating the air inside the bubbles. The heat is transferred into your swimming pool and this why professional recommends the bubbles to face down when being installed.

As well, the cover works by trapping warmth in your swimming pool, so on chilly days; your swimming pool’s water will keep the heat that was gained during the hot warm days – the bubbles will come in handy when trapping this heat.

This cover employs a simple but effective mechanism that will allow you to dive into your pool comfortably during the cold days.

Bubbles Facing Up

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.

In Conclusion

If you didn’t know whether to install your solar pool covers bubbles up or down, you have now understood what to do. Think of your pool cover as a thermal sheet for your pool. As the rays from the sun heat your cover, it begins to warm the water under it and depending on the amount of time it remains in your pool, it will trap the heat even if the temperature drops.
