How to Choose the Best Solar Pool Rings

There are a number of factors to consider and these include:

Solar Rings Quality

Solar rings for pool heating are designed from two sheets of heavy-duty vinyl. They trap sunlight energy, warming the water in your pool and, at night, they offer an insulation layer ensuring that heat is not lost from the pool. Due to their constant exposure to sunlight, solar rings tend to crack and chip off from the edges with time.

To ensure your solar rings can last long, choose solar rings with thick vinyl layers. Again, ensure that the vinyl is UV resistant so it does not get destroyed by the sun.

A good solar cover can last up to 4 years but most last three years or below.

Size of Your Pool

Unlike other pool covers that cover the entire pool, solar pool rings cover small sections of the pool. This means that you have to buy many rings depending on the size of your pool. If you have a small pool, you can buy small sized rings to cover about 80 percent of your pool connected edge to edge by the fitted magnets. If your pool is large, shop for larger rings to ensure you do not buy so many.

Ring Design and Decorations

Most solar pool rings sport a blue layer that absorbs sunlight to heat water. The units are created in different shapes and sizes with most being circular or elliptical while others are triangular. On their top are different decorations; some have bubbles and others have palm trees while others are plain only with the brand name. When shopping, pick according to your likes and preferences.

Solar Ring Heating Power

Most solar run rings are able to absorb up top 50 percent of the sun’s energy to heat water in your pool. The rings are able to provide up to 21,000BTUs of heat to keep your pool warm at all times. When shopping, look at product specifications to see the heating power of the solar sun ring.

Affordability and Warranty

You can buy solar rings individually or you can buy them as a set. When you buy them as a set, they are less expensive making them affordable. However, the number of rings you buy will depend on the size of your pool.

When shopping, consider the warranty offered as it shows the trust the manufacturer places on their products.

How to Use A Solar Pool Ring

Solar rings have to be inflated to make them buoyant before they are placed on the surface of the pool. All you have to do is inflate the outer surface until it is firm and then inflate the inner portion just slightly. Place them on the surface of the pool and they will start heating your water.

Most solar pool rings are fitted with magnets on their edges making it easy for them to stay connected and cover more area on your pool. The magnets also keep your water clear and ensure the rings do not overlap. Rings or squares will not cover every part of your pool and as such, you can still run your pump. This is an advantage as it allows sunlight to pass through thereby reducing the growth of algae. It can also be a disadvantage as leaves and other particles still find their way into your pool.

Unlike other pool covers, solar pool covers can be removed easily; all you need is to detach the magnets and pull them out of the water.

How to Store Solar Rings

Solar rings are small elliptical or square pool covers; this makes them easy to store. When you are swimming, you can stack them somewhere on the deck of your pool, away from the wind.

Most solar covers feature a loop from which you can hang them when they are not in use.

If you want to store the rings for a long time, get them out of the water and spray them off. Use a soft brush to clean off debris when the rings are still inflated to ensure that no dirt is trapped in the wrinkles.

Next, dry the rings by hand. If you decide to dry them with a leaf blower, hold them so they do not fly all over your compound. Deflate the rings, flatten them and store them in their bag. If the rings did not come with a bag, store them in a lidded container. Rings should be stored away from sunlight and from abrasive surfaces.

Why Pick Solar Rings?

Solar rings are easy to use and they do not need a lot of maintenance. Unlike other pool covers that may need special tools to install, rings only need to be inflated and placed on top of the pool. They are designed to reduce the rate of evaporation, retain the heat of your pool after the sun goes down, keep debris and bugs out of the pool and have lower cost of pool chemicals.
