      I wasn't sure what to expect with this pool solar heater and was surprised how good this actually worked. Kids love the pool more because its a little warmer so still swim on cooler days. Shipping was fast. Thanks overstock.

      Verified Purchase

      Good product and value for the cost. I thought each purchase was 2 panels. I have a 12 x 32 above ground pool. It has gotten temps up to 80 - 81 but not warmer. But again for value good item. Might consider for a small cost to add 2 solar panel/pump hose around 25' to the bundle. But did the job this summer.

      This takes a lot of effort to put on and take off so it ended up pretty much just being stored along the side for the first year and after that we didn't even get it out so I would say save your money

      I expected more from the description. It is basically just a long strip of hard tube that the water runs through.

    • Great Solar Heater
      Verified Purchase

      This product worked wonderfully! It was easy to install (even for a novice like me) and the pool temperature has risen 10 degrees in a week - making it almost too warm, but that is better than freezing in my book. Just keep in mind that your pump has to be running for this to work as the water is pumped through the solar cell to heat it up. One other thing to keep in mind, the pump pressure isn't as great when the heater is hooked up - so if you want to vaccum your pool using a pump powered vaccum, you are better off disconnecting the solar heater first; but as I said, it is really easy to hook up and disconnect.

    • Sprung a leak as soon as it was hooked up
      Verified Purchase

      As soon as it was hooked up per instructions, it started spouting water through 2 tiny holes within two of the plastic tubes. Would have been a good slip-n-slide, but I had to unhook it so I didn't continue to lose water from my pool through the unit.

    • Nice product, but I needed 2 of them
      Verified Purchase

      This is my 2nd foray into solar pool heating. I bought a similar heater (different brand) summer 2011. When I went to hook it up this spring, one of the connectors broke! Since it is an odd configuration, I could not find any plumbing parts that could repair it, so i ended jerry-rigging it with various parts to get through the season. That made that heater functional, but it did leak, as i couldn't tighten down the connection appropriately. This fall, I bought the Sunheater to extend my swimming time; I am very pleased! The included (standard!) connections worked great; no leaks. My only criticism is that I have an 18' round pool, and while the documentation indicated that one heater would be enough, I think I really needed 2, as the increase in temperature was negligible. I will be ordering a second unit for use in the spring, and it looks like connecting the 2 together will be a breeze!

      The upside it that this solar heater worked great - heated our pool six degrees the first day. If you can set this up right next to your pump you will have it made. The downside is we had to puchase $100.00 worth of hose and fittings to set it up, could not set it up right next to the pool pump.

    Questions & Answers

    • Q:

      "A pool store told me that if you do not disconnect at night, this will run and cool the water down. It's this true? "

      • A:

        Don't have to disconnect. Just turn it off. If you get a "diverter valve" you can still run the pump as it will bypass the collector.

    • Q:

      "What size is this panel. "

      • A:

        This item is approximately 2 ft. W x 20 ft. L.

    • Q:

      "Can this be used with a diverter so the heater is not in use when your water is warm enough? If so, is there a specific one needed for this unit?"

      • A:

        Hello majiqlady, I'm positive you would be able to use a diverter. I couldn't find that we have one available on

    • Q:

      "How many heaters are shown in the above photo? Can you tell me is it attached to anything or leaning up agains the pool? We have an 18" round 48" high. The heater I purchased last year didn't work at all. I'm looking for something new and this looks like it might do the trick. Thanks, Ruth"

      • A:

        Hello Ruth, thank you for your inquiry. Unfortunately, the information you have requested is currently unavailable. You will receive an email notification once an answer is posted. Have a great day.

    • Q:

      "do I need to buy a kit to hook this up or hose?"

      • A:

        Hello Benjamin M., this solar heater comes with the needed hookups. I hope this helps. Have a great day!

    • Q:

      "Why did you choose this product?"

      • A:

        replace the one I have

      • A:

        Because of the review saying it heats up 10 degrees a week. I have six grandkids that love the water and I hate to see their chattering teeth. And we will use it on our hot tub when swimming season is over.

      • A:

        To heat my pool.

      • A:

        Had a propane heater. This should be better.

      • A:

        Looks like a quality product, had 4.5 Stars and the price was very good. We go through these items about 1 every 2 years. WE even keep the pool pump running but this last year in Western Washington it kicked the panel behind. So bought 2 of them, we have 16 x 32 above ground and down to 5 feet. So we have to heat about 13,500 gallons. 2 panels should keep us around 80 to 84 degrees. We had 1 panel and it would get us up to 78 to 82 degrees depending on how hot it was outside.
