The Ultimate Buying Guide To Solar Pool Covers
When purchasing a solar pool cover, looks should be the last thing on your mind. There are certain features you need to look out for that will be the most effective at bringing down energy costs and protecting your pool water from debris and other contaminants.
Solar pool covers give you two options, clear and tinted. Clear pool covers attract more sunlight, due to which, the pool temperature is raised to higher degrees. However, clear pool covers are not the best at retaining heat and your pool will cool down just as quickly as it heated up. Tinted pool covers do not heat up the pool as much as clear ones, but it will keep the water warm for a longer time. Make the decision based on where you live and how frequently you swim.
Solar pool covers in the market range from 8 mm to 16 mm. The thicker the pool cover is, the better it would be at retaining heat. They are excellent insulators and extremely durable. However, they get pricier the thicker they get. It should also be noted that trimming, washing, placing, and then removing thicker pool covers is a cumbersome task. If you handle pool maintenance on your own, opt for a cover with moderate thickness, around the 12-mm mark.
Solar pool covers come in rectangular, round, and occasionally, oval shapes. Choose the shape accordingly when making the purchase. In case of oddly shaped pools, you just need to choose one that will reach the farthest points of your pool. You can then trim and cut them to fit your pool shape.
An accurately sized solar pool cover should cover up your pool in all its entirety with at least 5 cm of the pool cover curled over the edges of your pool tiles. This way the cover leaves no opening preventing heat loss and protecting against dirt and debris. Before making the purchase, measure your pool size and purchase a cover a little larger than the exact size of your pool. The extra material makes it easy for you to tuck in the cover ensuring no gaps are left. This can further prevent the cover from being blown over when the wind picks up.
Choose the solar pool cover mechanism that best suits your needs and budget. Some solar covers can be placed and removed manually. However, some pool covers – especially larger and heavier ones ‑ are more feasible to use with a small motor that rolls and unrolls the cover.
Always opt for solar covers with lots of air bubbles in it. The air bubbles are what absorb sunlight and help keep your pool water nice and toasty. Also make sure the air bubbles are facing down into your pool water to get the best results.
