My Buying Guide on ‘Solar Cover For 21′ Round Pool’

As a proud owner of a 21′ round pool, I understand the importance of keeping it clean and well-maintained. One of the essential accessories for any pool owner is a solar cover. A solar cover not only helps in retaining the heat of the pool but also keeps debris and leaves out, reducing the need for frequent cleaning. After researching and using various solar covers for my pool, I have compiled this buying guide to help you choose the best one for your 21′ round pool.

Size Matters

The first and foremost thing to consider while buying a solar cover for your pool is its size. A 21′ round pool requires a solar cover specifically designed to fit its dimensions. Make sure to measure your pool accurately before making a purchase. It is better to opt for a slightly larger size than your pool’s measurements to ensure complete coverage.

Material and Thickness

The material and thickness of a solar cover play an important role in its performance and durability. The most commonly used materials for solar covers are polyethylene, vinyl, and polypropylene. Out of these, polyethylene is considered the most durable and long-lasting option. The thickness of the cover also makes a difference in how well it retains heat. Thicker covers provide better insulation but can be heavier and more challenging to handle.

Shape and Design

Solar covers come in various shapes such as round, oval, rectangular, etc., but it is crucial to choose one that is specifically designed for your 21′ round pool. The design of the cover also matters as some come with bubbles or air pockets that help in trapping heat while others have a smooth surface.

Solar Efficiency

The main purpose of investing in a solar cover is to retain heat in your pool. Therefore, it is essential to consider the solar efficiency of the cover before purchasing it. Look for covers with high UV-resistance as they can withstand harsh sun rays without getting damaged easily.

Accessories Included

Some solar covers come with additional accessories such as straps or clips that help secure them in place or make it easier to remove them from the pool. It is always beneficial to opt for covers that come with these accessories included as they can save you time and effort.

Budget-Friendly Options

Solar covers can range from budget-friendly options to more expensive ones with advanced features. It is crucial to evaluate your needs and budget before making a purchase decision. While cheaper options may seem attractive initially, they may not perform well or last long-term.

Maintenance

Maintaining your solar cover properly can extend its lifespan significantly. Look for covers that are easy to clean and maintain as this will save you time and effort in the long run.

Customer Reviews

Before finalizing on a particular brand or model, make sure to check customer reviews online. These reviews can give you valuable insights into how well the product performs in real-life situations.

In Conclusion

A high-quality solar cover is an essential investment for any 21′ round pool owner looking to keep their pool clean and warm all year round. By considering factors like size, material, design, efficiency, accessories included, budget-friendliness, maintenance needs, and customer reviews, you can make an informed decision on which solar cover will best suit your needs.
