    Solar Heaters

      It works very well. What a great idea!
      It's so easy to hookup and use. It has had no effect on my pump and filter. On a bright sunny day my pool water was 76 degrees and the water returning to the pool using the beluga and 100 feet of black hose, was 83 degrees! It really works very well. Well worth the money!

      Better than expected
      I have had this working all summer and it does an excellent job. It kept our pool warm (typically cools 1-2 deg/night w/ cover only - cold here at night) and comfortable. We attached 125' of black rubber hose, coiled it, and it worked wonderfully. (Advice for the person who couldn't get it to attach: go to a home store and spend about $1.38 for a reducer or adapter. Ask for help and someone can fix this for you.)

      Like it -
      I bought this a few weeks ago and it does work well to warm the water. Water coming out was 80 degrees and going back in was over 90. We were pleased! Now that fall is here the sun is just not quite warm enough to do much but I think it will work great in the spring and maybe help us get in sooner and not have to use the solar cover so much in the summer. --- We have 4 50' black hoses hooked to it. The only reason I didn't give it 5 stars and just 4 instead is b/c it does come apart ... read more some but once you have it on - just let it be and it will work. Don't try to over adjust or it comes apart.

      3 Years is about Max on this Cover
      As far as it's usefulness in warming the pool it did a great job along with our solar heater. Keeps the pool warm from the cool nights. I have owned this cover for 3 seasons and noticed for about the last month or so of using it, when I would take it off to swim there were little blue circles floating around in my pool. Which tells me the cover is degrading and will not be very useful as little plastic circles are not what you want to swim with. I feel they should change the warranty on this to ... read more 3yrs because for a 7 yr warranty it doesn't cover it after the first 2.

      Does what it's supposed to do
      Bought the 18' round for my 18' round pool and it was too big! Scissors fixed this problem. This doesn't heat as well as the silver cover but was less money.

      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.

      Great quality
      I was going to buy the cheaper solar cover but I am so happy I upgraded!my pool is 28 ft but decided to go with a 24 ft size to make it easier to take on and off.The size works perfect and because it's a heavyweight cover the water holds its temperature regardless of the smaller size!My pool is the warmest it's been in years!I also purchased the Hayward Power-Flo LX pump last year and it's so quiet and powerful making cleaning the pool a breeze!Everything comes within days of ordering it...very nice!

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

      Works great!!
      Purchased two to heat my 24ft round above ground pool. Works great, when it’s sunny. Has already extended my swimming season by a month. Normally I would not have even opened the pool. For those reviews that complain of leaks I wonder if it was assembled correctly? Followed directions and correct setting for divertor valve and no leaks anywhere

      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.

      Excellent service
      This is a great product. Pool temperature started increasing shortly after use. The containers leaked slightly during delivery. In the Swim replaced both containers without question and I received them the next day!! Awesome!

      Great Idea
      In our California drought conditions, I am trying out this Coverfree product to reduce evaporation from my pool. In the last 2 weeks or so I think the evaporation rate has dropped by about half. So far so good.

      Good product
      I've been using CoverFree for a couple of years now. While a don't have data from a side by side comparison, the scientific rationale seems sound and the pool does seem warm. My reason for not giving this five stars has to do with shipping and handling. The box arrived wet, as one of the two bottles leaked. Upon opening it I noticed the cap was loose causing roughly 2/3 of the liquid to leak out into the carton. A quick call rectified the matter and a new one was set out with dispatch. One ... read more suggestion...perhaps you can instruct your pickers/packers to give the cap a quck twist to tighten it beore sealing the shipping carton.

      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.

      Great quality for the price!
      Very happy with the quality and value of this solar pool cover. It shipped quickly and I've been very happy with anything I have purchased from In the Swim. Quality, value and service are amazing!

      Good product
      Good quality product at a good price. It's thick and we have had it on the pool for about two weeks and can tell a huge difference in the temperature.

    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.
