Intex 47 Inch Solar Pool Heater Mat
If you’re hunting for the best solar pool heater review that combines efficiency with simplicity, the Intex 28685E Solar Pool Water Heater Mat might just float your boat—or rather, warm your pool. Measuring a neat 47 by 47 inches, this black solar mat uses solar technology to boost your above-ground pool’s water temperature by a cozy 5 to 9 degrees, depending on how generous the sun feels. Its 11-square-foot surface area efficiently absorbs rays, making it a smart choice for pools up to 8,000 gallons. What stands out is its compatibility with filter pumps under 1/3 HP or flow rates less than 2,000 GPH, which keeps it user-friendly and economical.
Pros
The Intex solar mat is impressively lightweight at just over 6 pounds, making installation and seasonal storage a breeze—folding it up for winter is as painless as folding a beach towel. The heavy-duty UV stabilized PVC ensures durability even under harsh sun exposure, so you’re not left with a brittle mat after one summer. Plus, the included hose attachments and bypass valve offer flexibility for different pool setups, which means fewer trips to the hardware store. Its ability to gently raise water temperature without electricity is not only eco-friendly but also wallet-friendly.
Cons
While the heater does a fine job raising temperatures, it might leave you wishing for a bit more heat on chillier days, as the temperature boost maxes out around 9 degrees. Also, the mat’s size, while generous, may require multiple units for larger pools, which could complicate installation and increase costs.

Cons
While the SunCOIL excels in above-ground and soft-sided pools, it’s not designed for in-ground pools, which limits its versatility.

Lastly, the black coil tubing, while effective, might not be the most visually appealing addition to your pool setup if aesthetics matter to you.
