Why Solar Covers for My 18 Ft Round Pool are Necessary

When I first got my 18 ft round pool, I quickly realized how important it was to keep it in great condition, and that’s when I discovered solar covers. One of the primary reasons I invested in a solar cover was to maintain the water temperature. Living in a region where the nights can get a bit chilly, I found that the solar cover helped retain heat during the night, allowing me to enjoy warmer water during the day without needing to run the heater constantly.

Another reason I find solar covers indispensable is their ability to reduce evaporation. I noticed that without a cover, my pool would lose a significant amount of water to evaporation, especially during hot summer days. By using a solar cover, I not only save on water bills but also minimize the amount of chemicals needed to keep the water balanced. This means more time enjoying my pool and less time worrying about maintenance.

Finally, the safety aspect cannot be overlooked. As a pool owner, I’m always conscious of the safety of my family and pets. A solar cover adds an extra layer of protection, reducing the risk of accidental drowning and keeping debris out of the water. Overall, investing in a solar cover for my 18

My Buying Guides on ‘Solar Covers For 18 Ft Round Pool’

When I decided to invest in a solar cover for my 18 ft round pool, I had a lot of questions and considerations. After some research and personal experience, I’ve compiled this guide to help you navigate your options and make the right choice for your pool.

Understanding Solar Covers

Before diving into the specifics, let me explain what a solar cover is. Essentially, it’s a large sheet of material that sits on the surface of your pool when not in use. It harnesses sunlight to warm the water, reduces evaporation, and keeps debris out. When I first got mine, I was amazed at how much warmer the water was and how much less I had to clean the pool!

Key Features to Consider

  1. Material:

I found that solar covers are typically made from either bubble or reinforced vinyl. Bubble covers are lightweight and easier to handle, while reinforced vinyl is more durable but can be heavier. I opted for a bubble cover because it was easy to put on and take off.

  1. Thickness:

The thickness of the solar cover affects its insulating properties. I discovered that thicker covers (around 12 mils or more) tend to retain heat better, but they can also be more expensive. For my pool, a cover around 8 mils was a good balance between cost and efficiency.

  1. Color:

I learned that color plays a role in performance. Blue covers are popular for their ability to absorb heat, while clear covers can let more sunlight through to warm the water. I chose a blue cover, and it really helped heat my pool quickly during sunny days.

  1. Size and Fit:

Since I have an 18 ft round pool, I made sure to choose a cover that was specifically designed for that size. It’s essential to get the right fit to avoid heat loss and ensure easy handling. I recommend measuring your pool beforehand to avoid any surprises.

Installation and Maintenance

  1. Ease of Use:

When I first used my solar cover, I realized how important it was to have a cover that was easy to put on and take off. Look for features like built-in handles or a roller system if you want to save your back from heavy lifting!

  1. Storage:

After the pool season, I needed to store my cover properly. I recommend getting a storage bag or a roller system to keep the cover safe from damage during the off-season.

  1. Cleaning:

Keeping the cover clean is essential. I learned that a simple rinse with water and a soft brush will do the trick. It’s crucial to avoid harsh chemicals that could degrade the material.

Budget Considerations

When I was shopping for my solar cover, I found a wide range of prices. Generally, you can expect to spend anywhere from $30 to $150, depending on the material, thickness, and brand. I set a budget that allowed for a quality cover, knowing it would save me money on heating costs in the long run.

Customer Reviews and Recommendations

Before purchasing, I read several customer reviews. I found it helpful to see what other pool owners had to say about their experiences. I recommend checking online platforms or local pool stores to get insights into various brands and models.

Conclusion

In my experience, investing in a good solar cover for my 18 ft round pool was one of the best decisions I made. It not only helped maintain a comfortable swimming temperature but also reduced my maintenance work significantly. I hope this buying guide helps you find the perfect solar cover for your pool. Happy swimming!
