Why an 18 Foot Pool Solar Cover Is Necessary

From my experience, having an 18 foot pool solar cover is absolutely essential for maintaining a clean and warm pool. I noticed that without a cover, my pool lost a lot of heat overnight, making it uncomfortable to swim early in the morning or after sunset. The solar cover acts like a blanket, trapping the sun’s heat and keeping my pool water warmer for longer periods, which means I can enjoy swimming even when the air temperature drops.

Another reason I find the solar cover necessary is how it helps reduce water evaporation. Living in a dry climate, I saw my pool water level drop quickly, forcing me to refill it frequently. With the solar cover on, evaporation is greatly minimized, saving me both water and money. Plus, it keeps debris like leaves and bugs out of my pool, cutting down on cleaning time and chemical use. Overall, the 18 foot pool solar cover has been a game-changer for me in pool maintenance and enjoyment.

My Buying Guides on 18 Foot Pool Solar Cover

When I decided to get an 18 foot pool solar cover, I wanted to make sure I chose the best one for my needs. Over time, I’ve learned what matters most, and I’m sharing my experience to help you pick the right cover for your pool. Here’s what I focused on:

Why I Chose a Solar Cover

I wanted to extend my swimming season and save on heating costs. A solar cover helps trap the sun’s heat and reduces evaporation, which keeps my pool warmer and conserves water. Plus, it keeps debris out, so my pool stays cleaner.

Size and Fit Matter

Since my pool is 18 feet in diameter, I made sure to get a cover that perfectly fits that size. If the cover is too small, it won’t protect the water efficiently; too large and it might bunch up or be hard to handle. I always double-check the exact pool dimensions before purchasing.

Material Quality and Thickness

I looked for covers made of durable UV-resistant polyethylene or similar materials. Thickness is usually measured in mils — I went with a 12-mil thickness because it’s sturdy enough to last several seasons without tearing, yet flexible enough to handle easily.

Bubble Design and Heat Retention

The bubble side of the cover should face down toward the water to absorb and retain heat effectively. I found that covers with larger, well-formed bubbles do a better job trapping heat, which was key for me during cooler months.

Weight and Ease of Handling

Some solar covers can be heavy or bulky. I preferred a lightweight design that I could easily spread over and remove from my pool by myself. If you want, you can also consider getting a reel system to make handling easier.

Durability and Warranty

Because I wanted my cover to last multiple seasons, I checked for UV protection ratings and warranties. Many quality covers come with 1-3 year warranties. This gave me confidence that my investment was protected.

Price vs. Value

While shopping, I compared prices but focused more on the value offered — durability, size accuracy, and heat retention. Sometimes paying a bit more upfront saves money long-term by reducing heating costs and replacement frequency.

Additional Tips from My Experience

  • Always remove the cover during heavy storms to prevent damage.
  • Keep the cover clean and dry when stored to prolong its life.
  • Use pool cover clips or tie-downs if you live in a windy area.

By keeping these points in mind, I found an 18 foot pool solar cover that fits my pool perfectly and keeps the water warm and clean. I hope my guide helps you find the ideal cover for your pool too!
