      We enjoy our pool longer with our solar panels.
      Once panels are connected and sun arrived our pool was enjoyed dinner with warmer temperatures.

      Good solar heater - our pool is 82 by May 1
      We were skeptical that solar would work here in PA, but it sure does, we get the water warm quickly and have a month extra to enjoy the pool. By late June we don't need the heater, until after Labor Day. Have had this heater for 3-years now, and was asked to review. Left it on too long last season and had it 90 degs on memorial day (way too hot), so yeah it works. Be sure to install more than you need tho, if you wanta longer swim season.

      Love our solar cover
      We ordered a solar cover for our 24x54 above ground pool. Came in 4 days. We put it on 3 wks ago with in 48 hrs it raised the temp 10*. We swam today for the first time this year. When we took it off the water temp was 90* Our neighbors still can't swim! They are ordering one lol.

      Really heats up pool!
      I love how this heats up our pool. We've had a cool summer, but this cover makes the pool have an inviting temperature.

      Keep our pool warm & clean
      I buy a new solar cover every summer as we keep it on all the time except when we are using the pool. We live in a farming area & this keeps our pool much cleaner & because it is a solar cover, it is always warm & ready to use when we are ready! Because we leave it on all the time, it disintegrates by the end of the summer, but I have tried the more expensive ones & they do the same. I like the thickness of this one better than the lower priced one.

      Just what I expected
      Bought this product when we opened the pool for the season this year. It arrived promptly and is of good sturdy construction. The size is correct as advertised and it help to maintain the water temp in the pool during the cooler nights

      Easy to install!
      I just installed this dome heater and can’t comment on the heating yet. It was easy to install although it would have been better if the hoses screwed to the index fittings! I was lucky to have additional adapter parts handy.

      Works well
      Works well my pool is shaded but this is the perfect solution to the shade. A little difficult to set up.

      Great product/Great Service!
      Just received 3 of these and they were very easy to install. My pool had previously been set up with a tube heater from intheswim so installation was super easy. Less than an hour and they were up and running. We have had very rainy, cloudy days since then but they do seem to be heating as advertised.

      Not too hot....
      So far, I've only noticed minimal heating. However, the water evaporation is greater than when using me solar blanket. But then, maybe my expectations were too great.

      Works pretty good in the in ground pool.
      Wondering if this can be used in the hot tub, especially in the winter. We do use a solar blanket in the hot tub, but this added might work even better. We have cold long winters here.

      Great Product Does all it Claims to do!!!
      Bought for my daughters pool. She uses it regularly during the summer pool season and simply loves it. It is truly a Great Product for conserving pool chemicals and water temperature.

      A Solar balnket to be proud of!
      After having our in ground pool over 32 years we have gone through several solar blankets, but this one we receive 2 weeks ago appears to be the best one ever. It is well sized and much thicker than our previous ones. We have been blessed with more rain and some cooler days and nights , but we have been able to swim almost every day in comfort. It keeps our pool temperature up and seems to do a great job. We will have to wait to determine the durability of the blanket.

      Saves water usage but wears out fast
      This is the second such solar blanket ordered, but I am somewhat disappointed by how the blanket holds up after usage. My last solar blanket lasted just a little over a year and has several holes that seem to be caused by the chlorine and the sun.

      Does not lie flat.
      Solar blanket does not lie flat. Very wrinkly even after on pool after a few weeks. 12 ml is as expected. However disappointed in the looks of this. Did not have this problem with my other ones.

      Seems to be good quality!
      Seller was great on delivery. The cover is thick and heavy.... may need a different reel....trying to beef the one we have up. The color is not clear at all... but I didn’t except it to be by other reviews. I think it will be a good cover for us. I wish a cover was provided with this for when it’s on the reel....would extend the life of the solar cover...but, getting to be a lot of covers! Winter, solar, cover for solar cover...all in all... I like it! Just on pool a week tho... make up your own mind!

      Good price great solar blanket
      I have big lazy l 18ft by 42 ft total shaped pool so bought the 18 by 36 ft version and cut it into 6ft sections also got a 12 by 20 one and cut 2 ft off it for use covering stairs then cut the remaining 12 by 18 into two more 6 ft sections fits like a glove almost perfectly and us easy to remove each section for storage. Keeps all the heat locked in and in sunny days will even heat the pool above the 90 degrees.

      Best one yet
      We are on our third solar cover in the last 10 years. This one seems to not only work to heat the pool the best, but is also the thickest. I hope it lasts longer than the last one (4 years).

    In The Swim Knowledge Pool: Solar Pool Heaters

    In The Swim's Dr. Pool

    Harness the Power of the Sun

    In The Swim has solar pool heaters for inground pools and solar pool heaters for above ground pools. Capture the sun´s energy and put it to work heating your swimming pool! Solar pool heaters work well in all parts of the U.S., placed in any backyard area with daily unobstructed sun. Modular above ground pool solar heaters connect quickly to the pool return hose, and inground solar heaters are mounted to a nearby roof, rack or fence. 


    Pool Solar Heater Benefits

    • •  Most affordable pool heater you can buy, and free to operate
    • •  Environmentally friendly - no emissions, and no fuel used
    • •  Simple DIY installation by any handy homeowner

    The best feature of solar pool heaters is the free pool heat, after a low initial cost. In addition, solar pool heaters start great backyard conversations!

    How Solar Heaters Work: Inground or above ground solar pool heaters circulate pool water through black tubes that absorb the sun’s heat. A solar panel bypass allows you to control the flow rate through the solar panels and turn the system off during rainy days or after dark. Facing the solar panels in a southern direction, tipped towards the sun will increase solar heating; 6 hours of daily, unobstructed sun is best for optimum heating.

    Will Solar Pool Heaters Work on My Pool? Solar pool heaters will work well across the entire country, as long as you have a sunny spot near your pool pump that gets 4-6 hours of direct sun. Heat output depends on several factors, including the size of the solar system in relation to the pool, whether or not the pool is covered, and how many hours of daily sun the pool and solar panels receive. Good-sized solar heater systems can add between 15-20° F to your pool water, in all regions of the country, and smaller solar systems can easily add 5-10° F. 

    How Many Solar Panels are Needed? The more solar panel surface area you have (Sq. Ft.), the more solar energy you can transfer to the pool water. Inground solar heaters are typically sized to 40-50% of the pool surface area, but shallower above ground solar heaters are best sized to match 20-30% of the pool surface area. Calculate the pool surface area in square feet, and then use the multiplier to buy enough solar panels to match the result. The more solar panels you add, the greater the heat gain. 

    Solar Pool Heater Installation

    Above ground solar pool heaters are built for simple installation. Simply cut the return hose and connect the hose ends to the bypass kit, to allow you to reduce the flow rate into the solar panels (slower is best for heat absorption). Using a 3-way diverter valve, or two 2-way valves will allow you to bypass the solar panels completely, during rainy days or after dark, or if the pool becomes too warm. 

    Inground pool solar heaters may require advance planning for placement of the 10' or 20' long solar panels, and some PVC plumbing to route the water into and out of the solar panels. Our 10' and 20' panels can be placed directly on the ground, but for best results, mount onto a roof or rack, facing south. The Bypass Valve Kit is used for control of flow into the solar panels, and to bypass the system completely during inclement weather, and at night.
