Unless you are one of those adventurous (if not crazy) polar bear individuals who like diving into an ice-cold pool, you perhaps want to keep your pool warm. But before you hit the market and buy that expensive gas or electric heater, have you thought about a solar pool cover?
What is a solar pool cover? How does it work? How do I install it? If that what you are thinking, then you are in luck, because we are going to look at a solar cover for above ground pool or in ground pool.
What is a Solar Pool Cover?
A solar pool cover doesn’t just keep debris and dirt out of your swimming pool; it heats the water. It captures the heat from the sun and transfers it straight into your pool to keep it warm. Depending on your location, this cover might not keep your pool as warm as a gas or electricity heater, but the tradeoff is that it saves you dollars by reducing evaporation.
How does it work?
A solar pool cover functions as a magnifying lens to amplify the sun’s ray effect. If you have ever held a magnifying lens between a sheet of paper and the sun, you probably know how that works.
However, you need to remember that not all kinds of solar cover functions the same way or produces the same effect, therefore, the key is getting the right cover for your swimming pool as well as lifestyle.
How do I install it?
Now we will look at one of the most frequently asked questions: Solar pool covers bubbles up or down? Down is the right answer.
These covers work by the sun rays heating the air trapped within the bubbles. The heat is then transferred into the water, and this is why you should ensure the bubbles face down toward the water. Additionally, the covers work by trapping heat in your pool, so on cold days; your pool’s water will retain the energy that is gained during the day – the bubbles will help to trap this heat.
This cover uses simple but effective tech that will enable you to swim comfortably during the swim season.
If you install the cover while the bubbles are facing up, the process of heating your pool might take longer and even damage the bubbles. This is because the bubbles aren’t facing the pool’s water directly. They simply overheat in the sun with nowhere to transfer the heat. This means that the Rays need to flow via another layer (the cover) before they reach the water.
If you were wondering whether to put the solar covers bubbles up or down, now you know which the best side is. Think of these covers as thermal blankets for your swimming pool. As the sun’s rays heat up the solar cover, it starts to warm the water lying below it, and depending on how long the cover remains in the water, it will retain the heat even when the temperatures drop.
