Why an 18 Foot Pool Solar Cover Is Necessary

From my experience, having an 18 foot pool solar cover has been a game-changer for maintaining my pool. First, it helps me save a lot on heating costs by trapping the sun’s warmth and transferring it to the water. This means I can enjoy a comfortably warm pool without constantly running my heater, which definitely lowers my energy bills.

Another reason I find it necessary is how it keeps the pool cleaner. The cover acts as a barrier against leaves, dirt, and debris, reducing the time I spend cleaning. Plus, it helps slow down water evaporation, which means I don’t have to refill my pool as often. Overall, the solar cover not only saves me money but also makes pool maintenance much easier, letting me focus more on relaxing and enjoying my pool.

My Buying Guides on 18 Foot Pool Solar Cover

When I decided to get an 18 foot pool solar cover, I realized there are several important factors to consider to make the right purchase. Here’s what I learned and what helped me choose the best solar cover for my pool.

Why I Chose a Solar Cover for My Pool

I wanted a way to keep my pool warm without spending a fortune on heating. A solar cover helps trap the sun’s heat, reduces evaporation, and keeps debris out. It’s an eco-friendly and cost-effective solution that really made a difference in my pool’s temperature and maintenance.

Size and Fit: Why It Matters

Since I have an 18 foot diameter pool, I made sure to get a cover specifically designed for that size. A proper fit ensures maximum heat retention and prevents gaps where heat can escape or dirt can enter. I measured my pool carefully and looked for covers labeled for 18-foot pools to avoid any hassle.

Material Quality and Durability

I looked for covers made of high-quality polyethylene with UV inhibitors because they resist sun damage and last longer. Thicker covers tend to be more durable but can be heavier. I found a good balance with a 12-mil thickness, which was sturdy yet manageable to handle.

Bubble Design and Heat Retention

Most solar covers have bubble wrap-like air pockets to trap heat. I preferred covers with larger, well-formed bubbles because they provide better insulation. The bubbles also help float the cover on the surface, maximizing sun exposure.

Ease of Use and Handling

Handling an 18 foot cover can be tricky. I looked for covers that are lightweight and flexible enough to roll on and off easily. Some come with reel systems, which I highly recommend—they make covering and uncovering the pool much faster and less of a workout.

Color Options and Their Benefits

Solar covers come in blue, clear, or even black. I chose a blue cover because it offers a good balance between heat absorption and preventing algae growth. Clear covers absorb more heat but may encourage algae, while black covers retain heat but reduce sunlight penetration.

Cost vs. Value

I compared prices but focused more on quality and warranty. A cheap cover might save money upfront but wear out quickly. Investing a bit more in a reliable cover with good reviews saved me money over time by reducing heating costs and pool maintenance.

Maintenance Tips I Follow

To keep my solar cover in good shape, I rinse it regularly to remove debris and let it dry before folding to prevent mildew. I also store it in a shaded area during winter to prolong its life.

Final Thoughts

Buying an 18 foot pool solar cover made a noticeable difference in my pool’s warmth and upkeep. By focusing on size, material, ease of use, and durability, I found a cover that suits my needs perfectly. If you’re considering one, keep these points in mind to enjoy a warmer, cleaner pool all season long.
