Why My 18 Ft Round Solar Pool Cover Is Absolutely Necessary
I’ve found that my 18 ft round solar pool cover is an absolute game-changer for maintaining my pool. First, it helps keep the water warm by trapping the sun’s heat, which means I can enjoy swimming even when the air temperature drops. Without it, my pool water would cool off quickly overnight, making it less inviting and shortening my swimming season.
Another reason I rely on my solar cover is to reduce water evaporation. Living in a dry climate, I noticed how much water I was losing daily before using the cover. By simply placing it over the pool, I save gallons of water each week, which is great for both the environment and my water bill. Plus, it helps keep debris like leaves and dirt out, so I spend less time cleaning and more time enjoying my pool.
Overall, my 18 ft round solar pool cover makes pool ownership easier, more economical, and more enjoyable. It’s a small investment that pays off in comfort and convenience every time I swim.
My Buying Guides on 18 Ft Round Solar Pool Cover
When I first started looking for an 18 ft round solar pool cover, I quickly realized there are several important factors to consider to get the best value and performance. Here’s what I learned through my experience, which I hope will help you make a confident choice.
Why Choose a Solar Pool Cover?
I wanted to keep my pool warm without racking up my energy bills. A solar pool cover uses the sun’s energy to heat the water naturally while reducing evaporation. This not only saves money but also helps maintain cleaner water by blocking debris.
Size and Fit
Since my pool is exactly 18 feet in diameter, I focused on covers designed for an 18 ft round pool. It’s crucial to get the right size — too small won’t cover the surface properly, and too large can be tricky to handle and may not fit securely. Measure your pool carefully and look for covers labeled specifically for 18 ft round pools.
Material Quality
I found that the thickness and durability of the cover material matter a lot. Most solar covers are made from polyethylene with UV inhibitors to resist sun damage. A thickness between 8 to 12 mils is ideal for balancing heat retention and durability. Thicker covers last longer but can be heavier.
Bubble Design and Heat Retention
The bubble side of the cover should face down toward the water to maximize heat absorption. I looked for covers with well-defined bubbles because they trap solar heat effectively. Some covers have larger bubbles that can provide better insulation, so check product descriptions or reviews for details.
Ease of Use and Storage
Handling an 18 ft cover can be cumbersome. I appreciated covers that came with a reel system or were compatible with one, as it made removing and replacing the cover much easier. Also, consider how easy it is to fold and store the cover when not in use.
UV Protection and Longevity
Since the cover will be exposed to direct sunlight daily, UV resistance is key to prevent premature wear and tear. Look for covers that specifically mention UV inhibitors or protection to ensure your investment lasts several seasons.
Price and Warranty
I compared prices from various brands and found that the cost often reflects material quality and additional features like reinforced edges or UV protection. A warranty is a good sign of the manufacturer’s confidence — I recommend choosing a cover that offers at least a 1-year warranty.
Additional Tips from My Experience
- Always remove the cover during heavy storms to avoid damage.
- Clean the cover regularly to prevent buildup of dirt and algae.
- Store the cover in a shaded, dry place when not in use to extend its life.
By keeping these points in mind, I was able to find a solar pool cover that fit my 18 ft round pool perfectly, helped me save on heating costs, and kept my pool cleaner. I hope these insights make your buying journey easier!
