    Solar Heaters

      easier with parts from the harware store
      Why spend $50, when for the price of a few PVC fitting one could make a device that works just as good and doesn't come apart

      Awsome Heater
      Just received Beluga today. Cold water goes in and hot comes out. Simple. And if a leak happens we just replace the hose.

      Well worth it
      We purchased this approx 3 weeks ago as the water isn't swimmer friendly until mid-June. Very satisfied, heated the 14,000 gallon pool n two days. Purchased some brackets from the local hardware store n mounted them on the side of the pool. Spaced 4 of them approx 6 ft apart n works fine when tKing it off. I'd say this was well worth it for the kids. They love it

      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.

      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.

      It's hotter than a solar blanket....Easy to Use.
      Keeps temperature up, controls loss of heat, so easy to use. No more solar blankets needed!

      It worked!
      I bought this as we have had a cold summer. My 3 year old granddaughters birthday party was to be a pool party here. I put it in and with clouds and mid 80 temps it raised the temp of water 5 degrees in 4 days. All the kids had a blast. So I am sold on this product! Well worth the money!

      Good pool cover at a great price
      Bought this pool cover a month ago and had to cut it to fit my irregular shaped pool. Nice quality pool cover. The bubbles don't seem as full of air as my old cover but maybe that's because my old cover was very old. Can't say how it will hold up as it is still new. Only time will tell. The cover does not raise the temp of my pool anywhere near 15 degrees. I guess it depends a lot on what the weather is like in your area. Hear, it is pretty mild. However, the warranty does state that it will not ... read more cover air bubble damage at all. Warranty only covers de-lamination or separation at the seams.

      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.

      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.

      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.

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

      Great Item

      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 Even Better Than Expected
      Like to swim only in warm water 82-84 F, thus a pool cover to keep heat loss to a minimum is a MUST. After reading up on Troublefreepools.com I decided on a near clear color and top of line 16 mils as bubble-type solar covers go. While my Intex UltraFrame pool is only 12x24 I ordered the 18x36 cover and cut to size. Will use rest to wrap around the pool sides (under a deck) for added insulation. Pool is heated by a geothermal heatpump, now only running about 2 hrs a day to maintain above ... read more temperatures even after cool nights. Pool is in partly shaded location. Use a PoolBoy motorized reel with remote control, well worth it compared to manually turned reels. Easy one-person operation.

      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).

      Rockin' Hot
      This pool cover really heats up the pool. We have turned off our solar water and rely on just this cover for heat. However, we have to monitor the water tempurature otherwise it will get too hot. So we need to leave the cover off for a night or too to cool the pool. But we love it and it saves us $$s for heating. This will extend our swimming season.

    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.
