As a pool owner, I have learned the hard way that investing in a 21 ft solar cover is an absolute necessity. At first, I was skeptical about its effectiveness and saw it as an unnecessary expense. However, after using it for just a few weeks, I realized how crucial it is for maintaining my pool.

First and foremost, a 21 ft solar cover helps to keep my pool water warm. The sun’s rays are absorbed by the cover and transferred to the water, keeping it at a comfortable temperature even on cooler days. This not only allows me to enjoy my pool earlier in the season but also extends my swimming season well into the fall.

Furthermore, having a solar cover significantly reduces the amount of debris that enters my pool. Leaves, twigs, and other debris are prevented from falling into the water by the cover. This saves me countless hours of cleaning and also helps to keep my pool filter from getting clogged.

Another major benefit of using a 21 ft solar cover is its ability to prevent evaporation. During hot summer days, pools can lose up to an inch of water per day due to evaporation. Not only does this result in higher water bills but it also means constantly having to refill your pool. The solar cover acts as a barrier

My Buying Guide on ’21 Ft Solar Cover’

Introduction

Hello, my name is [Your Name] and I have been a pool owner for several years now. During the summer months, I love spending time in my pool but I noticed that my pool water would get too cold at night. That’s when I decided to invest in a solar cover for my 21 ft pool. After researching and trying out different options, I have put together this buying guide to help others who are looking to purchase a 21 ft solar cover.

What is a 21 Ft Solar Cover?

A 21 ft solar cover is a large sheet made of durable plastic material that is specifically designed to cover swimming pools of the same size. It is placed on top of the water surface of the pool and helps to retain heat from the sun’s rays, keeping your pool water warm.

Benefits of Using a 21 Ft Solar Cover

  1. Increase Water Temperature: A solar cover can increase the temperature of your pool water by up to 10-15 degrees Fahrenheit.
  2. Reduce Evaporation: By covering your pool with a solar cover, you can reduce water evaporation by up to 90%, which means less frequent refills and more savings on your water bill.
  3. Cut Down on Chemical Usage: With less evaporation, there will be less need for chemical treatments, resulting in cost savings and better water quality.
  4. Prolong Swimming Season: Using a solar cover can extend your swimming season by keeping your pool warm even during cooler months.

Factors to Consider Before Buying

Before purchasing a 21 ft solar cover, here are some important factors that you should consider:

  1. Type of Material: The most common materials used for solar covers are polyethylene or polypropylene. Polyethylene covers tend to be more affordable while polypropylene covers are more durable.
  2. Cover Thickness: The thickness of the cover determines its durability and effectiveness in retaining heat. Thicker covers tend to be more durable but also more expensive.
  3. Solar Efficiency: Look for covers with high solar efficiency ratings as they will be able to retain more heat from the sun’s rays.
  4. Cover Shape and Size: Make sure you measure your pool accurately before purchasing a cover. A 21 ft solar cover may not fit all types of above-ground or in-ground pools perfectly.

Tips for Maintaining Your Solar Cover

To ensure that your 21 ft solar cover lasts longer and remains effective, here are some tips for maintenance:

  1. Clean Regularly: Remove any debris or dirt from the surface of the cover using a leaf skimmer or soft brush regularly.
  2. Avoid Sharp Objects:Avoid walking on the cover with sharp objects such as shoes as they can puncture or tear it.
  3. Treat with Care:Gently remove any wrinkles or folds before placing it on the pool. Avoid dragging it across rough surfaces as it can damage the material.
  4. Store Properly:If you plan on storing your solar cover during off-seasons, make sure it is completely dry before folding it up and storing it in a cool, dry place away from direct sunlight.

The Verdict

Purchasing a 21 ft solar cover for my pool has been one of the best investments I have made. It has not only extended my swimming season but also saved me money on energy bills and chemical treatments. After considering all factors mentioned above, I highly recommend investing in a high-quality solar cover for anyone who owns a 21 ft swimming pool.

I hope this buying guide has been helpful in making an informed decision about purchasing a 21 ft solar cover for your pool. Happy swimming!
