      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

      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.

      Beluga Works Great So Far
      I've had the Beluga installed for several weeks with 100' of black rubber hose. It has raised the pool temp at least 10 degrees up to 86. So far I'm satisfied with the performance. The durability is still a question.

      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.)

      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.

      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.

      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.

      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!

      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!

      Solar Blanket
      Love the ease of this Solar Blanket!!! It covers my pool exactly and is easy to remove and place on (we do not currently have a separate reel, so are manually placing and taking off). The temperature after opening our pool increased wonderfully and we were able to enjoy our pool by May 18th!!

      Superior design solar blanket.
      Excellent product, small clear solar cells on a silver blanket. Fits perfectly. Delivered promptly. It keeps out wind blown debris, keeps heat from escaping at night and warms the water when the sun shines. Rolls up compact and neat on my solar reel.I had many solar covers in over thirty years of pool ownership and I am very impressed by this cover. ( purchased in June 2019). Hopefully If it will has a good life span.

      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.

      solar cover keeps pool warmer
      I’ve had solar covers on my pools for years. They keep the pool warmer and I don’t have to use a lot of chemicals due to evaporation. Together with a solar heater I increase water temperature about ten degrees .

      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.

      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.

      Rate as a 1 or a 5?
      My "rating" space is limited. The blanket does as advertised but the warranty is worthless. Be prepared to add a lot of plastic to the trash stream when the cover decides to fail. In order to get the most out of the product and reduce your guilt about all the plastic: Do not cover the pool after shocking it. Do not step on it compromising the bubbles. Do not drag it in over the edge of the pool, again compromising the bubbles. Do not leave it in the sun when reeled in. Do not leave it ... read more out in freezing winter weather. This is my third or fourth blanket and you need to remove it once it starts to become friable. Those little blue floaties are no good for your filter.

      Love it!
      We are so pleased with our solar cover. It has kept our pool warmer than we expected (76) with cool nights going down as low as 56 degrees! Also keeps it cleaner, with our pine trees shedding, and keeps water level from going down. It has extended our swimming season here in New England. Love it!

    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.
