    Solar Heaters

      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.

      Love my solar blanket.
      I bought this 18x36 solar blanket to warm my pool water up. My water temp was 69,I put the blanket on and within a week my water was 88 degrees. It’s up to 90 degrees now. I am so glad I purchased this product I would recommend to purchase this if you want your pool water warm and to stay warm all summer. We will probably be swimming way into October with the blanket. I live in Oklahoma,stays warmer longer than back east

      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.

      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.

      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

      Love it!
      I bought this Beluga about a week ago, and love it. I only have it attached to 2- 50' garden hoses (will get 100' more) and it is raising my water temperature 2 degrees per day. We have a lot of shade, so it's really a great idea! All I did was coil the hoses on the ground and run the beluga! Absolutely love this idea!!!

      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.

      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!

      Solar cover
      This Solar cover increases the water temp in our pool by about 8 degrees. Fits well, came very fast and I hope it lasts longer than the last one we had. The pool chlorine is hard on the cover and It eventually starts to tear and come apart.

      I was so surprised at how thick this blanket was. Although we bought it at the end of the season, it seemed to keep the water warmer than our old blanket.

      Great quality for the price!

      AWESOME Product
      I purchased this solar blanket to replace my last one. I have a large pool and need to use the solar blanket for about 5 months ever year. It is an ideal product to reduce the amount of temperature and evaporation loss of your pool every evening. As an example I normally lose only 3 to 4 degrees of water temp when the air temp drops to low 50s overnight. With no cover I would lose twice as many degrees without the solar cover.

      Solar blanket
      Received the incorrect size, so I had to reorder. This meant I had two charges on my card until they received the return. The second blanket was the correct size, but it is constructed of two different shades of blue vinyl.

      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.

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

    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.
