Why You Need a Good Solar Pool Cover

Here are a few reasons you need a swimming pool cover besides merely helping heat the water in your swimming pool.

Energy Costs and Savings

An average gas pool heater can use around 4 gallons of propane an hour. Likewise, natural gas can use around four therms per hour.

If you were to use electric heat pumps, you are looking at 5 kilowatts per hour.

Reduce Evaporation

Your pool may lose an average of 2-inches of water per week without a cover. Depending on pool size, this could amount to 10 to 20 thousand gallons of pool water evaporation each year. Furthermore, your pool’s evaporation loses 75% of your pool temperature.

Chemical Loss

Pool cleaning chemicals reduce with evaporation or dilute them as you add more water. Pool covers save chemical reductions by two-thirds.

Algae & Trash

You can find either of these swimming around in your pool. But unfortunately, algae can take over, and trash makes the water look unhealthy.

Longer Swim Season

Solar pool covers help you extend your swimming season. You can find you may swim for another month, at least.

Solar Rings

When you see these solar sun rings, they connect. The rings make a sort of raft, and in between, there are gaps. Rings may appear easy to use, yet rings can allow algae to form. You also tend to find solar sun rings are not as efficient in warming your water.

Solar Pool Cover Buying guide

Blanket solar pool covers are an inexpensive means to extend the swimming season. They are an ideal option as no other pool cover can increase the temperature of your water. However, it would help to consider a few things to get the most effective.

If these don’t suit you, there are always the liquid solar covers, yet they won’t stop debris.

Type of Pool

The sort of pool you have makes a huge difference. You can have an in-ground pool or an above-ground pool. If yours is in-ground, you may need to invest in a particular type of cover reel.

Size is also vital, and while you can cut a solar pool cover for the size of your pool, you need to know the measurements first. In addition, a round solar pool cover is not as flexible as it is purpose-made for round pools.

Ease of Use

You’ll find that not all blanket pool covers are user-friendly. First, you can find automatic, semi-automatic, or manual. It would help if you had more effort with manual, yet they are significantly cheaper. Next, you find these often-called passive solar covers.

A semi-automatic blanket has reel systems, though you need to guide your cover. Automatic blanket solar covers are a fully functional system where they cover and uncover your pool.

Material Types

Pool covers are made from different types of materials. If you don’t have the right material, it may not function properly or last very long. Vinyl covers are durable, yet you still need to understand the quality, affecting heating capacity and heat retention.

It would help if you also saw how the tiny air bubbles fasten as some can fall off after a time.

Colors

Solar pool covers come in a variety of colors. The darker blue color offers better heat protection, although too dark, and it will begin to keep your swimming pools cooler as the light can’t pass.

Semi-transparent covers allow UV rays a chance to pass through your cover and heat the water. The cover then deters water evaporation and prevents heat loss. With this is the thickness as this also helps retain heat.

You may have a color and design, yet these don’t affect performance.

Final Verdict

In testing, we put the solar pool cover best suited to the job through different criteria. The goal was to see how warm the swimming pool water got and how long the heat could be retained compared to Thermo Tex Solar.

It was clear that the Sun2Solar Clear 16-Foot-by-32-Foot Rectangle Solar Cover would be the heavy-duty solar champ in many of the tests. It took the heat from the sun and kept it in the water longer than others.

Add in the drain holes, which made it easier to remove than other offerings filled with water. While the heat retention pockets perform well in-ground, there is nothing to convert to fit above-ground pools.

Do this, and you probably have one of the best pool covers for above-ground pools.
