Best Overall: Sun2Solar Blue Rectangle Solar Cover

Sun2Solar Blue

Featured Specs

  • Type: solar heater
  • Mounting Type: blanket cover
  • Size: 12 x 24 foot
  • Warranty: Yes


The Sun2Solar Blue Rectangular Solar Cover is a perfect option for rectangular above ground pools. It features an eye-catching blue blanket with a film of thousands of small bubbles. These thick functional bubbles help retain pool heat on chilly days and nights.

According to Sun2Solar Blue, the solar heater can reduce water evaporation by 95% and pool heat warmth by 15%. The perfect heat insulation allows you to jump into warmth with ease and comfort in the cold, teeth-biting weather.

The solar cover is an ideal heating solution. It doesn’t rely on electricity or fossil fuels. All it needs is solar energy to work, which, in turn, reduces the overall heating cost.

To enjoy the best free heat, you simply have to place the bubble-side of the cover facing toward your pool water. This allows your solar blanket to absorb UV rays and preserve heat within the pool for a long time.

So, enjoying a relaxing swim during the sweater weather is no feat as long as you have this top-class heater for above ground pools.


While the solar pool blanket comes with a warranty, unfortunately, it’s too limited to anyone’s liking. The limited warranty is only enough to cover linear seam separation. Also, some users have had issues with the bubbles falling off after a couple of uses.

This results in the contamination of the pool. If you keep on using the cover even after it’s gotten damaged, you may risk littering your pool with tiny pieces of plastic.

Extra Features

Your pool could be of any size and shape, right?

The Sun2Solar Blue Heat-Retention Cover is flexible which means it can be molded into any form. Whether you have a small or big pool, square or rectangular, the solar blanket will fit into any size and shape in an instant. 

Owing to the cover’s resin material, your pool has a greater chance of maintaining clean water. The solid, durable cover prevents dirt and debris from entering the swimming pool. During extreme heat conditions, the cover also prevents water loss and evaporation.

What’s more, the cover can be found in many models. Its heavier versions are fit for areas that get strong winds and rainfall.

Buying Advice

Without any shadow of a doubt, the Sun2Solar Blue Cover is the best above ground pool heater out there.

It makes use of free heat from natural light and absorbs and retains it so you can enjoy swimming in the offseason as well. This one gives all the great features of a pool heater at a minimal cost. Thereby, it’s worth it.
