    Solar Heaters

      Solar cover
      It didn’t seem to make the temperature rise that much

      Works great!
      I had not planned on buying a solar cover until fall but an unexpected cold spell prompted me to buy one now. It arrived in only two days and when the night temps dipped into the 50's the pool stayed in the mid 80's. As the temps climbed back into the 80's and 90's, the pool quickly warmed up into the low 90's. I have it stored for now, but knowing fall is around the corner we will be swimming well into October. Highly recommend however, it is heavy so get a good reel the one I have works ... read more great but you need two people due to the weight.

      Heavy Duty
      I haven’t installed it yet but it’s high quality. I bought a lighter weight one from you before. It did last for two years. It probably would have lasted longer if I had stored it better during the super hot desert summers

      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 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

      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.

      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.

      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.

      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.

      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.

      Very pleased with new solar cover!
      Bought this a couple of weeks ago. It warmed the pool up ten degrees in a couple of day’s and already has our pool water the perfect temperature. It has cut the amount of pool chemicals used by half. This is our 2nd cover - the one before lasted about 7 yrs, then we didn’t have one for a few years. I had forgotten how many benefits there are for using this type of cover. We are very pleased - these covers are worth their money!

      As advertised -durable solar cover
      Needed two round solar covers - great price, very durable covers - better than expected for the price

      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

      Super fast shipping!!
      Ordered this in the morning and received the next morning! Wow, 24 hours!! Love the cover; works great!

      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.)

      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.

      Simple and efficient
      I wanted something that would help raise my in ground pool water temp about 10 degrees and don't have anywhere to install a solar panel so thought I would try this device out. Bought 2 of these units and attached 100ft of black hose to each. Simple to install took less than half hour. After about a week water temp is up 6 degrees only because it has been cloudy and raining. I have no doubt will allow us to enjoy pool about a month earlier than our usual season.

      Has worked great for the first week of installation.

      Great brand at nice price.
      Easy way to add more heat to extend the swimming season . Added unit to an existing solar heater

      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!

      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 well
      Very good product to use with Solar Sun Rings. In these drought conditions I'm saving many gallons of water. Evaporation is about 75% less than without these products. Also $10.00 less per unit than the swim centers.

    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.
