Why a Solar Pool Cover 18Ft Round Is Necessary
When I first got my pool, I quickly realized how much water and heat it was losing every day. That’s when I decided to invest in a solar pool cover, specifically an 18ft round one to fit my pool perfectly. Using this cover has made a huge difference in maintaining my pool’s temperature, especially during cooler nights. It traps the sun’s warmth, allowing me to enjoy a comfortable swim without constantly running the heater.
Another reason I find my solar pool cover essential is the way it helps reduce water evaporation. I used to refill my pool frequently, but since covering it, the water stays put much longer. This not only saves me money but also conserves water, which feels great knowing I’m being environmentally responsible. Plus, the cover keeps debris like leaves and dirt out of the pool, making maintenance easier and my pool cleaner.
Overall, my 18ft round solar pool cover has become a simple yet powerful tool that saves me time, money, and energy while keeping my pool inviting all season long. If you want to get the most out of your pool, I highly recommend getting one that fits your pool size just right.
My Buying Guides on Solar Pool Cover 18Ft Round
When I decided to buy a solar pool cover for my 18ft round pool, I quickly realized there were several important factors to consider. Here’s what I learned through my experience, which I hope will help you choose the best solar pool cover for your needs.
Why I Chose a Solar Pool Cover
I wanted to save on heating costs and keep my pool water warmer for longer. A solar pool cover helps trap heat from the sun, reducing evaporation and keeping debris out. It’s an eco-friendly and cost-effective way to maintain my pool temperature.
Size and Fit Matter
Since my pool is 18 feet in diameter, I looked specifically for covers that matched this size or were slightly larger. A cover that’s too small won’t provide full coverage, and one that’s too large can be cumbersome to handle. I recommend measuring your pool diameter carefully before buying.
Material and Thickness
I found that solar covers come in different thicknesses, typically measured in mils. Thicker covers (around 12-16 mil) are more durable and provide better insulation, but they can be heavier. Thinner covers are lighter and easier to handle but may not last as long. I chose a medium-thickness cover to balance durability and ease of use.
Bubble Design and UV Protection
The bubble design on the underside of the cover is crucial because it traps heat effectively. I made sure the cover had well-defined bubbles to maximize heat retention. Also, UV-resistant coatings help the cover last longer under sun exposure, so I looked for covers with good UV protection.
Ease of Use and Storage
Handling an 18ft round cover can be tricky. I looked for covers that were lightweight and came with a reel system or storage bag to make covering and uncovering my pool easier. This saved me a lot of time and effort.
Cost vs. Quality
Price was a factor, but I didn’t want to compromise on quality. I compared several options, read reviews, and chose a reputable brand that offered a good warranty. Spending a bit more upfront meant I got a longer-lasting cover that performs well.
Additional Tips From My Experience
- Clean your cover regularly to prevent algae buildup.
- Remove the cover during heavy winds or storms to avoid damage.
- Use a cover pump to remove excess water from rain.
By keeping these points in mind, I found a solar pool cover that perfectly suits my 18ft round pool, making my swimming season longer and more enjoyable. I hope my guide helps you make a confident purchase!
