Why My 18 Ft Round Solar Pool Cover Is Necessary
From my experience, having an 18 ft round solar pool cover is a game-changer for maintaining my pool. First, it helps me keep the water warm by trapping the sun’s heat, which means I can enjoy swimming even when the air gets cooler. Without the cover, my pool water would lose heat quickly, and I’d have to spend more on heating.
Another big reason I rely on my solar cover is that it significantly reduces water evaporation. I’ve noticed that when I don’t use it, I have to keep refilling the pool more often, which wastes water and increases my utility bills. The cover keeps the water in and also helps prevent debris like leaves and dirt from falling in, making pool maintenance easier and saving me time.
Overall, the 18 ft round solar pool cover not only saves me money but also makes my pool experience more enjoyable and hassle-free. It’s a simple investment that has made a noticeable difference in how I care for my pool.
My Buying Guides on 18 Ft Round Solar Pool Cover
When I decided to get an 18 ft round solar pool cover, I wanted something that would keep my pool warm, reduce evaporation, and save me money on heating. Here’s what I learned through my experience, which I hope will help you make a smart choice.
Why Choose a Solar Pool Cover?
From my experience, solar pool covers are fantastic because they use the sun’s energy to heat the water naturally. They also help keep debris out, which means less cleaning for me. Plus, they reduce water evaporation, saving water and chemicals.
Size and Fit Matter
Since I have an 18 ft round pool, finding the right size cover was crucial. I made sure to measure my pool’s diameter accurately. A cover that’s too small won’t protect the entire surface, and one too large can be difficult to handle. For an 18 ft pool, an 18 ft round cover is usually perfect, but always check the dimensions carefully.
Material and Thickness
I found that the thickness of the solar cover affects both durability and heat retention. Covers typically range from 8 to 16 mil thick. Thicker covers last longer but can be heavier to manage. I chose a medium thickness that balanced durability and ease of use. Also, look for UV-resistant materials to avoid quick wear and tear.
Bubble Design and Color
The bubble side should face down on the water to trap heat. I made sure to check this when unrolling the cover. As for color, I noticed that darker blue covers tend to absorb more heat, while lighter blue or clear covers let more sunlight pass through. I opted for a blue cover that offered good heat absorption without making the pool water look too dark.
Ease of Handling
Handling an 18 ft cover can be a bit cumbersome. I recommend looking for covers that come with a reel system or are compatible with one. This made covering and uncovering my pool much easier, especially on windy days.
Durability and Warranty
Since I wanted my investment to last, I chose a cover with good customer reviews for durability. Some brands offer warranties, which gave me peace of mind in case of defects or premature wear.
Price and Value
Prices can vary widely. I balanced cost with quality because a cheaper cover might not last the season, and a very expensive one didn’t necessarily offer much extra benefit for my needs. Reading reviews and comparing features helped me find the best value.
Additional Tips from My Experience
- Always clean and dry your cover before storing it to prevent mold and damage.
- Use a cover pump to remove excess water from rain or debris.
- Consider investing in a solar cover reel for convenience.
- Check local climate conditions—solar covers work best in sunny areas.
By keeping these points in mind, I was able to find an 18 ft round solar pool cover that helped keep my pool warm, clean, and enjoyable throughout the season. I hope my guide helps you make the right choice!
