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

I have 5 panels now, it has been 2 years and working well. It heats my pool greatly in the summer to my content I wish it would make it as warm in the winter but the planet does not work that way. I enjoy my pool now. Summer temp can be up to +34c and winter around+28

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.

Ordered this product twice and returning both of them. Both orders said the product was "USED-Good As New". First order received in a banged up box, all parts loose inside. Easy to install pool solar water heater. Came as 2 panels as expected, 1 panel had a hole in the middle of the panel which wasn't detected until installed and water pressure applied and we had a nice fountain on the roof. Set up a return product with Amazon and ordered a 2nd system. Box worse than the 1st order, product smelled terrible of animal urine and covered in dog(?) hair. Installed where 1st system had been. Noticed a patch of JB Weld fixing a hole and small seepage of water through the joints. Sending back #2 and just purchased NEW system from Lowes. Called manufacturer, SUNHEATER. They cannot support used re-boxed systems, but they were extremely helpful in getting the right NEW system for my needs.

I’ll try to stick to the info a purchaser might want to know. Pool used on: Intex XTR 12’ x 24’ above ground (8500 gallons, saltwater) Panel config: four 2x20 panels on garage roof, East facing w full sun 9 am to 6 pm. Approx 100 ft total distance to and from, using 1.5 HP Hayward pool pump. The system pumps about 400 gallons per hour. Heating results We initially installed two panels last fall, and ran that a while before we decided to expand. Two would have been sufficient, but since we were already running a pump and the pressure was high we decided that four would perform better. I opened the pool from winterization in early March, when we were getting days that were highs of 70 and lows of 48 at night, UV peaking at six. The pool started at 55 degrees, and it only took 3-4 days running the system for 6 hours per day to get up to 70. From there, I was able to manage running it to get +8 degrees per day, losing 2-4 at night, working up to 80. Now our weather is sunny with daily temps of 55/72 and I’m running the system about 3-4 hours each morning to get from 78 to 84. Overall, these are great results that allow us to extend the season quite a lot in either direction. Also, running the system at night cools the water. It’s possible this will come in useful if we have any severe heat waves. Product performance: A Durability and quality: B+ Overall, the panels are good quality. They come tightly rolled up and mishandling them could cause issues. We simply laid them out with some bricks on towels weighing them down, and after a week in the sun they were straight and ready to go up on the roof. The fittings require a lot of Teflon tape, but I expect that from this sort of product. Installation: B I wish the instructions were a little clearer. It comes with a variety of fittings and caps that were mostly intuitive, but not detailed well in the manual. It would also be nice if the company would provide more configurations. If I recall, the printed guide had a schematic for two panels and four without really specifying if they were rooftop or yard. It seems like their customers might have a variety of mounting/installation configurations, and it’d be nice for the manufacturer to post schematics for these on their website...such as a poolside or yard setup, or better guidance on securing these on a roof. That said, there are many online videos from people that can help someone design their system. I recommend viewing these in advance, because you may need some add’l minor hardware. I think mostly all we bought in addition to the provided hardware was some better brackets to bolt things down to protect from wind. Overall, we are very happy with the purchase. The system gives us moderate control over our water temp at a very low energy cost. We’re excited to have it for our second pool season.

Last night after the sun went down we were in our 88 degree water with visible steam rising from the surface. It was awesome. The average daily temp in PA where I live has been less than 70 degrees since we filled the pool and about 78 the past 4 days. Last year I might have been able to get the water temperature up to 78 this week had I been very meticulous with the solar cover. So I'm crediting these solar panels with a 10 degree improvement. The panels were actually the least expensive part of the project. All together I spent about $1000 for this set up, but I had a lot of fun doing it. My house is too far away from the pool to run pipe through the yard and up to the roof. The pool gets only about 4-5 hours of sunlight a day, but the area around the pool gets up to 9 hours of sunlight per day. The problem is this: the area with sun changes from the west side of the pool to the east throughout the day. So how can I capture sun all day long for heating purposes? Build a "roof with wheels"! Despite being 20' long, I can easily wheel this thing around by myself. The solar panels are connected to the pool with 1-1/4 flexible sump pump pipe. I originally T-ed this into my filter pump, but I found that trying to run it using the same pump as the filter created too much resistance for the filter to effectively clean the pool; so I purchased a separate 1.5 hp pump just for the heating system I also created a separate outlet and inlet for this system so that I could pull colder water from the top of the pool and push warm water in toward the bottom ( on opposite sides of the pool). It might seem complicated, but it really works well, and we've got it down to one move of the panels per day at about 1pm. If you can put these somewhere that the get sun most of the time, and provide sufficient throughput, you will not be disappointed!

This product is working great thus far to warm up our round above ground pool, BUT the reason I only gave it 3 stars is because it was all a HUGE HASSLE!!! First of all, we ordered a double set of panels. One set was fine, but the other set was leaking the minute we hooked it up! Which was a HUGE HASSLE because this product is VERY HEAVY when it comes all coiled up and has to be laid out flat for awhile until it doesn't coil. We had to send for a replacement! UPS took a long time getting it to us, 3 days past the date they said it was "out for delivery"! I had to call Amazon to get them on UPS to get it delivered! Because of the whole COVID situation it took AWHILE for me to find a way to even talk to someone at Amazon. UPS delivered the pkg. FINALLY, but it was all banged up! Thankfully the product wasn't damaged, it was however missing one of the protective caps. The fault of UPS because it quite apparently had fallen out of the big whole on the bottom of the box! Thankfully the solar panel company sent us a GOOD set of panels that work the second time around! THEN, we had to pkg. up a double set of panels to mail them back! VERY HARD to do because the now un-coiled panels don't want to be re-coiled, and the plastic they're made of is VERY HARD to bend! UGH!!! This whole EXHAUSTING process SHOULD have had Amazon or the Solar Panel Co. sending US some kind of discount or compensation for all the TROUBLE This was!! So....IF you get panels that work well right off the bat then you will love this product because it isn't too hard to install and it IS significantly raising our pool temp! BUT......you are in for a real FIASCO IF the solar panel company sends you DEFECTIVE panels like they did to us!

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.

I'm just going on my second year using these. I ordered and installed 4 sets (8 panels) for my inground pool. I built a inclined, treated plywood platform for them to sit on and help them down with nylon strapping. I used a parallel connection pattern so none of my panels were daisy chained end to end to reduce the pressure drop and make life easier on my pump. Installation: Installation was easy but expect a couple trips to the store of you aren't connecting them to a above ground pool with a little hose. I had pin hole leaks in 3 panels to fix the first year, I used a little JB weld which seemed to work great. They definitely worked, The pooled heated up quicker and was able to stay open longer. If you have cooler nights even in the summer, I would definitely recommend adding a little intelligence to the system and get a controller that can control the valves or just manually check the weather for the day and decide if you want it on in the morning. For winter, I blew them out and pulled all my drain plugs. Starting them up this year, there were a few more pinhole leaks (my JB weld held fine over winter) and 2 panels had cracks in the small tubes right next to the big tube. Following their "recommended" procedure of putting a small screw in the hole didn't work, the plastic is now to brittle and it takes hardly any movement to cause another crack. If you live in a moderate climate they would probably hold up fine, we had -40F this last winter so it certainly a nice environment. Since all my infrastructure is in place I'm going to switch to my own "solar panel" using irrigation pipe. It was a fun experiment and the panels looked promising but overall they were just too cheaply made for my environment.
