SunHeater Pool Heating System Two 2’ x 20’ Panels – Solar Heater for Inground and Aboveground Made of Durable Polypropylene, Raises Temperature, 6-10°F, S240U Black

Within a few days and full sun it raised the pool from 65F to 80F (22'x52'' Pool with 10500 gallons). I am also using a solar blanket over night and during the day when the pool is not in use. I spent about $200 on wood frame and 1.5" pvc piping to feed and bypass the system. I added extra couplings for adjustments and easy take down for Winter. I even painted the PVC piping black to get every piece of energy....I feed it from the bottom corner on one end and take it out the upper corner on the other end (panels in parallel). I use threaded pvc couplers to attach the pvc piping to the panel. I did not use the provided couplers as they seem to reduce the flow more. I use a 14" intex sandfilter pump (2,800 GPH). A little increase in pump pressure and less flow into the pool when going through the panels (I also use an intex auto pool cleaner and it only really works when bypassing the panels). I wonder if a 3rd panel in parallel would help with getting the flow rate back up. I have some minor leaks (droplets of water from some of the little pipes) and I am waiting for a replacement (still give it 5 stars as exchange was a breeze with Amazon and they let me keep the old one until the new one arrives). Leaks are so little I can still run the system but for the price I expect absolutely no leaks. It comes tightly rolled up so I would recommend to let it sit in the sun and let it unroll/flatten itself.Overall it's a great system. It requires some space but this kind of heating system is all about surface area.

It works well but has multiple tubes with holes. Amazon has no method to contact other then the sellers form after multiple submissions, no responses.

I was so amazed for the hot water got out of this. You wouldn't appreciate it unless you've tried the electric heater. I tried 3KW 110v heater and it heat less than this thing. Not to mention the electric bill would go up the sky, the heater also heat up my extension cord after a couple hour and melt the plug. It was terrible and I decided not to use it anymore. I would probably use it in the winter if the solar doesn't work well enough. For now, I bought 3 of those and I got my 18x9x52 above the ground pool to 94 degree after 3 days installed it. It was amazing. Be careful to read the manual as my installation was wrong when I ordered one first. I was supposed to put the end caps at the other side but I did the other way around. I thought both ends are the same and water can go through. In fact, only the ones with no label don't have the barrier in the middle. It worked too regardless of my wrong installation, but I'm sure the correct way would be more efficient. Hope it would last a few years to recoup the money that would have paid for the electric bills. Good luck.

When I got this it was all rolled up so I had to let it lay on the ground for a few days for the sun to soften it enough to be more pliable. I also had to buy hardware to support it so I purchased some PVC piping which does an adequate job of supporting it. It took a few weeks to get done due to my schedule and the weather, and at first thought this wasn't a good way to up the temperature of the pool. But once I got it installed it started to do the job. There was one leak in the panel, a small one at that, which I plan to repair with an adhesive to block the tiny hole. But surprisingly I did not experience any other leaks once all the fittings were secure and in place. You definitely want to use plumber's tape as I have learned with operating a pool over the years!The installation was challenging, and now that it is set up the panel sags in a few spots (likely due to expansion now that it's all unfurled) but this will be corrected when I construct a better frame for next year.I had to add a bypass for the water flow into the pool, especially for cleaning purposes. This is because the water does become restricted in the main tubes at the side to force it to channel the water through the tubes where the sun heats it up. I installed a bypass with a valve so I could control when I wanted most of the water to go through as is to provide the cleaning power in the pool and when I wanted it to go through the solar panels. The bypass added some weight to one side of the panels so I added a pole to provide additional support.Overall this is a good product but do expect some work getting it set up (and that you need to provide your own frame to support it with). Now that the hot and humid weather finally arrived, we are seeing the benefits of this product. Just remember it will take several days to raise the temperature of the pool by as much as 5 to 10 degrees. Also keep in mind you'll have to be on top of cleaning the pool as the increased temperature can lead to an accelerated algae growth in the pool if not taken care of properly.
