SunHeater WS220P S220P Aboveground Pool Heating System, Includes One 2’ x 20’ Panel (40 sq. ft.) – Solar Heater Made of Durable Polypropylene, Raises Temperature Up to 15°F, Black

I have owned this product for years and since I leave it out I have developed a few leaks near lower seams. Because of this I added some y type PVC ball valves so as I start up pool no dirt will enter piping and allows me to fix any leaks by bypassing solar. I use only the pool filtering system on my 10,000 gal above ground pool. I did build a raised angled platform that faces afternoon sun. I have pool filter go on about 10:00AM as the day has started to warm. My pool water was 83 on july 4th 2016.I mentioned leaks some times hard to repair the last one took me a week to get my repairs correct (reason for ball valve ) pool wont lose water. Amazing how water can find away out. Origional price was $200 so I am almost tempted to buy another.You may think why did I give it 5 stars.... I hate cold water , live near Boston and able to get in my pool after Labor day.If my pool is below 75 I struggle to get in.This passive solar works for me. I ll try to get some photos

Leaks like crazy. Spent money on PVC and A new pump for my intex 9'x18' pool. Pump that came with it wasnt strong enough.I have had it running for a week, and no change in temp. I run it only in daylight, and absolutely no change in temp. Literally about 9 hours direct sunlight is beating on this thing. Leaks dont help, but figured I would run it for a week before posting a review. If it heted my pool at all, and leaked, I wouldnt care as much. But it is useless. Just a waste of time and money. Buyer beware. Junk! Absolute junk!

I have owned this product (Sunheater/solar collector) for approximately 5 years (give or take... long enough to be uncertain what year I bought it). The conditions: I have a 4' deep 18' round above ground pool (with a perfect fitted solar blanket) and I live in the northeast. Let me start off by saying it works amazingly well. Take this spring: I opened the pool in mid-May, and pool water temperature in one day (with direct sun-light on this product) raised the pool temperature from 69 degrees f, to 79 degrees f in one day. My neighbor down the street with only the solar blanket has just reached 78 degrees f and their pool had been open for 2 weeks prior. Same weather conditions, pool size is roughly equivalent, and my pool caught up to and surpassed theirs temperature-wise. By the following day the pool was at 82 degrees.How it works: Familiar with a radiator on a car? It's like that, but the reverse process. Clean water from the pool filter with pumped into one end of this "solar collector". The water is then sent through half the tiny black (black absorbs light and thereby heat) tubes on one side, hits the end, then comes back through the other half of the tiny black tubes. The idea is, you expose more surface area to the water, than if the tubes were bigger. Since the water is cooler than the solar heat being absorbed, the heat is being transfer to the water, and then returned back to the pool.Construction: these things are built to last. My first one I owned lasted up to this season, and was damaged by a lawn mower (I'm cheap and I just lay in on the grass; I've since built a ramp for it, like in the picture). The lawnmower caught the side of it and chewed through 4 of the tubes. HOWEVER, I was able to repair it. If you look at the manual([...] it instructs you to cut off the damaged tubes on both ends (where they meet the larger pipe) and drive in #10 sheet metal screws between 1/2" and 3/4" long. Worked great! I learned this after I had already purchased another one, so now have 2 solar collectors.Maximum heat threshold: Well that depends greatly on the temperature during the day and night. I used the example of when I opened the pool and the temperature shot up 10 degrees in one day. The next day it only went up a few more degrees. There is a peak it reaches, and it is directly dependent on the temperature during the day. On consistent 75 degree days, my pool will in the mid-80's. One year when we had three 92 degree days, my pool hit 102 degrees (yes, it was disgusting, but I wanted to see how high it would go, haha). I now used my pool up until October where before it, we closed it beginning of September. I think the closing temperature was 69 degrees this year... which is not back for the late September weather we had).Issues to watch out for: There are two. 1. Definitely rig up a diverter valve to bypass the solar collector. This should be included, but it is not. Everyone has a "too hot" and "too cold" temperature they prefer.... most just don't know they have a "too hot" temperature for a pool...at least not up here in the northeast. I know I do now. More importantly, when the temperature on the pool is elevated, it requires a more vigilant eye on the pool chems. Once a week treatments are not enough with temps in 85+ degrees. I ended up with a green pool twice this summer (went away for a few days). Keeping the pool temp down helps this.2. Use a solar cover/blanket on the pool at night. Without it, because the water is warmer than it normally would be, you'll fight a significant amount of evaporation. Adding water means diluting your pools chemical content, which means adding more chems.Problems with design: As I mentioned, there probably should be a diverter valve incorporated into this design, but there is now. The other issue I have (with the one I just bought, the older one doesn't have this problem) is with the end pieces that connect to the hoses. I use high quality pool hose, and I have to use 2 hose clamps on both to prevent it from leaking. Two hose clamps on both side (4 total) does fix the issue, but it's kind of annoying.Summary (tl;dr): I do wholeheartedly recommend it to everyone with a pool that wants it warmer, or squeeze out another month or two of usage...with the caveat that you build in a bypass to control the temperature from getting too hot (if you want), and use a solar blanket/cover to keep evaporation from being a problem (also stabilizes the temperature of the pool...evaporation = loss of heat = pool temperature going down at night).

We bought two panels for our 16x30' above ground pool and are extremely pleased with the results. Our pool was at 66 degrees and is now up to 88. We hung the panels on the fence by the pool and run the solar from 12:30-8:00 pm when the sun hits them straight on. We have also kept the solar blanket on when not swimming and have used the liquid heat shield that came with the panels. So I'm sure that has helped keep the heat in. But it's amazing to feel the not just warm but hot water coming straight into the pool from the panels when on.The connections are hard to tighten so I'm still getting drip leaks at several of the connections but overall we are very pleased with the results. Especially for the low cost overall.We ended up using two 3 way diverters (one from the filter to the solar panel and one from the solar panel to the pool with a tube in between) so we can bypass the solar panels at night. It took some trial and error to get it right but now it's working like a charm! The hardest part is remembering to turn the dials each night and morning. But I'll take it not having to use extra electricity to just heat the pool.

I know it's difficult to look @ a review and take it objectively. If someone had a bad experience it's one star and don't buy. I have to say that this is not the best product I've purchased. Does it work? Sort of. Not sure it was worth the price I paid for it though; about $125, it's worth about $60 in my opinion. I dare say if you really want it to work, you need to get a solar cover to help keep the heat in. The two work together fairly well. However; I have a friend who has just the solar cover and it seems to do the job by itself. Not sure if a second one would do the trick. I've a15' round and according to their chart 1 should be enough, but I'm not willing to spend another $125 to find out

Not sure why so many poor reviews as it worked VERY well for us and have used it for several years.

Je vient de l’installer est ça coule à 6 place est il dise de réparer avec des vis ça ne fonctionne pas

The solar heater arrived rolled up in a box. Because of its unrolled length I opted to do the unrolling on my roof. This was challenging because it tended to have a rolled-up memory, so being by myself on a sloping roof I had to be creative to make it stay flat and in place. My next frustrating task was to find PVC attachments that would let me connect the Sunheater to my existing solar heater plumbing. Eventually I decided to replace the provided elbows with PVC elbows which helped a lot. So far the benefit of adding this Solarheater to my existing system hasn't been overwhelming however I'm prepared to wait a while before deciding what to do next - after all, this was an experiment of low cost and minimal expectations.

Lots of leaks, need lots of Teflon tape to make the connections water tight. The ribs had several leaks that needed to be repaired. Does not provide much heat, better off with the D.I.Y. unit I was using before. Not worth the money.

I originally purchased this product abut 10 years ago. After about 5 years of use the first panel failed ( I have a system of 4 ). Since then I have had to replace at least one panel each year. This year 3 of 4 panels failed, including 1 that was new out of the box. Amazon was great and took the item back no questions asked despite the 30-day return policy date having lapsed. I have decided to cut my losses and look for a different product.
