My Buying Guide on ’21 Ft Round Solar Pool Cover’

When it comes to owning a pool, one of the most important investments you can make is a good pool cover. Not only does it keep your pool clean and free from debris, but it also helps regulate the water temperature and reduces chemical usage. As a pool owner myself, I have done extensive research on various pool covers and have found that a 21 ft round solar pool cover is the best option for my needs. In this buying guide, I will share my personal experience and provide you with all the necessary information to help you make an informed decision when purchasing a 21 ft round solar pool cover.

Why Choose a 21 Ft Round Solar Pool Cover?

As the name suggests, a 21 ft round solar pool cover is designed to fit pools with a diameter of 21 feet. This size is ideal for most standard above-ground pools, making it a popular choice among many pool owners. Additionally, the solar aspect of this cover means that it harnesses energy from the sun to heat your pool water naturally. This not only saves money on heating costs but also makes it an eco-friendly option.

Material

One of the most important factors to consider when purchasing any type of pool cover is its material. A 21 ft round solar pool cover is typically made from high-quality polyethylene material with air bubbles throughout its surface. These air bubbles are what help trap heat from the sun and keep your pool warm. Make sure to choose a cover with thick and durable material to ensure longevity.

Cover Thickness

The thickness of your solar pool cover plays a crucial role in its effectiveness. Thicker covers provide better insulation and can retain heat for longer periods. A good rule of thumb is to look for covers with at least 12 mil thickness or higher for optimal performance.

Shape and Design

A 21 ft round solar pool cover comes in different shapes and designs. The most common shape is round, as it fits perfectly on circular pools without any excess material hanging over the edges. However, some brands also offer oval-shaped covers that can fit oval-shaped pools as well. When choosing the design, opt for one with minimal seams or joints as they can be potential weak points for tears or rips.

Additional Features

Some 21 ft round solar pool covers come with additional features such as UV protection or algaecide treatment that helps prevent algae growth in your pool water. While these features may come at an extra cost, they can be beneficial in maintaining clean and healthy water in your pool.

Budget

Last but not least, consider your budget when purchasing a 21 ft round solar pool cover. Prices may vary depending on brand, materials used, thickness, and additional features included. However, investing in a high-quality cover may save you money in the long run by reducing heating costs and extending the lifespan of your cover.
