Why an 18 Ft Pool Solar Cover Is Necessary
From my experience, using an 18 ft pool solar cover has made a huge difference in maintaining my pool’s temperature. I noticed that without it, the water cools down quickly, especially during chilly nights. The solar cover acts like a blanket, trapping the sun’s heat and keeping the water warm for longer periods. This means I can enjoy swimming without constantly needing to reheat the pool, which also saves me money on energy bills.
Another reason I find the solar cover essential is how it helps reduce water evaporation. Since I live in a dry area, losing water quickly was a big issue before I started using the cover. It keeps the water from evaporating, so I don’t have to keep refilling the pool as often. Plus, it helps keep debris and dirt out, making pool maintenance easier and saving me time on cleaning.
Overall, the 18 ft pool solar cover has been a great investment for me. It extends my swimming season, cuts down on costs, and keeps my pool cleaner — all things that make owning a pool much more enjoyable.
My Buying Guides on 18 Ft Pool Solar Cover
When I decided to invest in an 18 ft pool solar cover, I quickly realized there are several important factors to consider to make the right choice. Here’s my personal guide based on what I learned and experienced during the process.
Why I Chose a Solar Cover for My Pool
I wanted a cost-effective way to keep my pool warm, reduce evaporation, and save on heating costs. A solar cover uses the sun’s energy to heat the water naturally, and it also helps keep debris out. It felt like a simple solution with multiple benefits.
Size and Fit Matter
Since my pool was 18 feet in diameter, I looked specifically for covers designed to fit this size. A good fit is essential because a cover that’s too small won’t provide full coverage, and one that’s too large can be cumbersome to handle. I measured my pool carefully and chose a cover labeled for 18 ft pools to ensure proper fit.
Material Quality and Thickness
I found that the thickness of the solar cover affects both durability and heat retention. Most covers come in thicknesses ranging from 8 mil to 16 mil. I opted for a mid-range thickness (around 12 mil) because it offers a good balance between durability and flexibility. Thicker covers last longer but can be heavier to manage.
Bubble Design and Heat Retention
The bubble side of the cover should face down toward the water. I checked that the bubbles were uniform and well-formed, as this helps trap heat effectively. Some covers have larger bubbles for better insulation, which I found beneficial in keeping my pool warmer during cooler nights.
Ease of Use and Handling
Since I cover and uncover my pool regularly, I looked for a cover that was lightweight enough to handle without assistance. Some solar covers come with reels or handles, which make the job easier. I eventually purchased a reel separately, which made rolling the cover on and off much more manageable.
UV Protection and Longevity
Sun exposure can degrade solar covers over time. I made sure to choose a cover that included UV inhibitors to extend its lifespan. This was important to me because I didn’t want to replace the cover every season.
Color Options
Solar covers come in different colors like blue, clear, or black. I chose a blue cover because it seemed to offer a good balance of heat absorption and water clarity. Clear covers heat well but can promote algae growth, while black covers absorb heat but reduce water clarity.
Price and Warranty
I compared prices across several brands and found that investing a little more upfront for a durable cover with a warranty was worthwhile. Many quality covers come with a 1 to 3-year warranty, which gave me peace of mind.
Final Thoughts
Buying an 18 ft pool solar cover improved my pool experience significantly. By paying attention to size, material, thickness, and UV protection, I found a cover that fit my needs perfectly. If you’re in the market for one, I recommend considering these factors to get the most value and enjoyment from your purchase.
