Why an 18 Ft Solar Cover Pool is Necessary
From my experience, having an 18 ft solar cover for my pool has made a huge difference in maintaining its temperature and cleanliness. I noticed that with the cover, the water stays warmer for longer periods, which extends my swimming season without relying heavily on a heater. This not only saves me money on energy bills but also makes swimming more enjoyable.
Another reason I find the solar cover essential is how it helps keep debris out of the pool. Leaves, dirt, and insects stay on top of the cover, so my pool stays cleaner and requires less frequent cleaning. Plus, it reduces water evaporation significantly, meaning I don’t have to refill the pool as often. Overall, an 18 ft solar cover is a simple, cost-effective way to protect and enhance my pool experience.
My Buying Guides on 18 Ft Solar Cover Pool
When I first decided to get an 18 ft solar cover for my pool, I realized there were several important factors to consider to make the best choice. Here’s what I learned through my experience that might help you pick the right solar cover for your pool.
Understanding What a Solar Cover Does
I found that a solar pool cover is essentially a large sheet, usually made of durable plastic with air bubbles, that floats on the surface of your pool. Its main job is to retain heat, reduce evaporation, and keep debris out of the water. Knowing this helped me focus on covers that excelled in heat retention and durability.
Size and Fit Matter
Since I have an 18-foot round pool, I made sure to get a cover specifically designed for an 18 ft diameter. A cover that’s too small won’t protect the entire surface, while one that’s too big can be tricky to handle and might tear easily. Measuring your pool accurately before buying is crucial—I recommend measuring the widest points and checking the manufacturer’s sizing guidelines.
Material Quality and Thickness
The thickness of the solar cover impacts how well it insulates your pool. I opted for a cover with a thickness of around 12 mils because it offered a good balance between durability and flexibility. Thicker covers can last longer but may be heavier to move. Also, look for UV-resistant materials to prevent the cover from degrading under sunlight.
Bubble Design and Heat Retention
I noticed that the bubble side should always face down into the water, as the bubbles trap heat effectively. Some covers have larger or more tightly packed bubbles, which can improve heat retention. I checked product details and reviews to find covers praised for their insulation capabilities.
Ease of Use and Storage
Handling an 18 ft cover can be cumbersome, so I considered covers that come with a reel or roller system to help with easy removal and storage. This saved me a lot of time and effort during pool maintenance days.
Budget and Warranty
Prices vary widely, and I set a budget keeping in mind that investing in a good quality cover would save me money on heating and chemical costs in the long run. Also, I looked for products that come with a warranty or satisfaction guarantee, which gave me peace of mind.
Additional Tips from My Experience
- Always rinse the cover with fresh water before storing it to prevent damage.
- Use a cover pump to remove excess water from rain or snow on the cover.
- Replace your cover every few years depending on wear and tear to maintain efficiency.
By keeping these points in mind, I was able to choose an 18 ft solar cover that keeps my pool warm, clean, and enjoyable throughout the swimming season. I hope my guide helps you make a confident and informed purchase!
