I made a DIY solar water heater for a friend that needed it for him and his family's jacuzzi! After doing a ton of research and getting a ton of help from RC Insider (who made a great video on this with a full supplies list), I went for it myself!
I made this water heater with:
1/2" exterior plywood
1/16" acrylic sheet
2x4x8 KD doug fir
2x4x8 Treated doug fir (though I wish I did 4x4)
8" zip ties
500' roll of 1/2" irrigation tubing
1/2" tube to hose connectors
Brass tube to hose connector
5/8" water hoses
A water pump
Lag bolts and nuts
Black latex exterior paint
Pocket hole screws
Deck screws
Tite Bond III wood glue
... and I think that's it!
I wasn't able to see it in person, but my friend shot me pictures (that are also in this video) of how a temperature reading of 120 degrees for the water coming out of the water heater and his current weather was 83 degrees!
Couldn't be more happy with that result since I thought I would be lucky to get 90/95 degree water.
Lots of lessons learned on this project since I usually do 100% woodworking furniture projects.
Also, shout out to my friend Ryan Geery! Without your help, I would not have been able to complete this project!
Hope you enjoy the build!

All new users (or any user for that matter) of a solar heater need to be very careful when turning the heater on after it has heated up if not done in the morning. The hot water that was sitting still in the heater tubes WILL scald your hand or anybody in the pool that's near the outlet. It will be scalding hot for about 2 minutes.

Cool project. When building a heater like this to heat a pool, do not focus on maximum output temperature, but instead focus on transporting as much heat energy as you can from the sun to the pool. Using two coils in parallel instead of one super long coil will decrease resistance and thereby increase the flow, you will heat up the pool faster, even if the temperature difference between input and output is only a few degrees. That is because more energy is transferred this way. Also beware that this solar heater can overheat when it is not in use and the tubes might melt, depending on the materials used.

pretty good and cheap approach, i did the same like 15 years ago using the black Gardena 1/2" plastic hoses from the microdrip system .. i bought 800 meters in 16 coils, i connected 4 flat coils in series and 4 of those strings in parallel to get a higher flow rate) on the roof of my garden hut, without any box around it. Unfortunately the wind fuzzed them up quite a bit when i had them emptied during the winter. I was thinking also of a boxed version, but never found the time to really build it .. i got stuck in thinking about which materials i should use, that i wanted to be waterproof but couldn't decide on the right material. This set of uncovered coils was bringing my water from 20 to 40 degrees in full sun in summer. Hint for creating the spiral: The trick that i found to get the flat spiral perfect and with least effort and without making a mess is: Keep the hose in its natural spiraling when it is delivered in a coil, put it onto the surface and then just pull it ring by ring into the flat spiral you desire.

Great video ! I've build something similar years ago but made one mistake. It was way too big so I couldn't handle it anymore. Eventually I had to cut it to pieces. Now, a new project similar to this is planned for the coming summer. This time much smaller individual panels that will be combined. I used garden hose (reinforced) from Gardena. After the summer you can buy these real cheap with lots of discount. It's easier to make sharp bend and it doens't fold as easy as the back tubing. With a simple microcontroller and a valve (recycled from a washing machine) you can slow down or stop the water flow when it gets late afternoon. The amount of water in the circuit will then slower get warmer and after a minute or so you can let it flow in a reservoir or so to accumulate. This worked out fine for me.

When I built mine, it was 4 x 8 and I used two pieces of corrugated skylight material, and I just replaced it this year because it was dirty, and I thought (from the ground, not the roof where it resides) that it had clouded. Now i think it was just dirty. Anyway, it holds up year round in Kentucky elements. I also filled any empty spaces with aluminum cans and painted everything matte black. Its the only way the pool in my yard is usable. I can't bring myself to cut the trees, and its a forest pool! This is a great video. I would buy one of these since I don't have the time and energy to build a second one.

To greatly improve this, you should not use a continuous coil. You really want to use a manifold for the entrance and exit with parallel small diameter tubes connecting the manifolds. This way every tube starts with water at the current pool temp... thus the greatest heat transfer rate.

I have two suggestions about the unit itself. First, if you were to feel the back (underside) of the collector on a sunny day, I could all but guarantee that it is hotter than young love. If you insulate that with a piece of foil faced 2" EPS foam, you would retain more heat inside the chamber. Secondly, use either a high temp caulk or gasket around the perimeter of your clear sheeting by doing this--along with a top piece of trim--will seal the heat inside the chamber and keep the warping to a minimum. The recommendation of a thicker sheet by another viewer is definitely a better choice, but the best would be one layer of tempered, not coated glass. Great video. I was frustrated with you in the beginning stage. I wanted to be able to tell you how to uncoil the tubing and that laying it in from the top was really the only way to do it. Thanks again for a good watch!

Nice video. Working with this irrigation tubing can be frustrating. I've not used it for this purpose, but for actual irrigation, but you run into the same problem (kinks especially as you try to unfurl from a large roll). A good approach is to unfurl the whole roll across a wide open space (backyard), carefully pulling loops off the coil as you unfurl the whole thing. Then run down the length of the tubing to untwist/unfurl some "memory" from your coil. If I were doing it now, I'd use smaller lengths of tubing in the first place rather a full 500' length. Buy the 500' roll for the price, but then unfurl as described previously and cut it to more manageable sections (maybe 100'), then use common irrigation tubing couplings to attach your sections to create your desired full length. The couplings might slow down your water flow a *little* (if you use the inside-tube/barbed ones) and would make your final coil less "clean" looking, but for me those would be acceptable trade-offs for the reduced frustration of trying to work with/lay down a single 500' tubing length :)

I built one with landscape style tubing...just be sure to keep water and circulation during sun hours or you will melt it down... I also used steel studs vs. wood. Made it lighter.

How to stop it from over heating my hot tub? I made one and it got my sauna (hot tub) up from 53 degrees to over 105 and the weather is still only 75 degrees outside. I can manually watch and turn the pump off when the weather gets really hot, but will the water boil in the solar collector? Should I let the water drain out of the tubes when I turn it off? Do you know an inexpensive sensor that will turn the pump off when the tub gets to a certain temperature? Thanks.

Yes - we decided to go with a different pump because the water was originally coming out too slow (which is why it got so hot). Now it is ~95 degrees and comes out faster (which in turn, heats up the jacuzzi better as well).

I built a jacuzzi heater with old windows black paper and dirt to seal air off under old windows laying on black roofing paper. Had a old roll of the same low pressure tubing. It was all kinked up. Eventually the kinks are where the leaks will happen over time. If the water does not flow to remove heat the temp can get close enough to boiling to cause half melted softer plastic to rupture. If pump works always when hot then this problem is reduced.

Hello Nick Thank you for the viedo. I want to do this but the hardest part for me would be building a box. Could I use an aluminum water heater 30" pan? This set up is fantastic. I bet someone could build them and sell them and make a nice profit. Also I want to put the solar pannel on my flat roof patio cover will any pump work? We live in California and limited on space the pool will go between pato and fence with inches to spare. Thank you in advance...

Wow sorry for the delayed response! I don't have the insight to speak to the aluminum water heater 30" pan (though I don't see why not?) but I have seen a couple of videos of people not even using a frame and just mounting it to their roof with good results. The things to consider would be the how powerful the pump is and angles the tubing would be inclined / declined but otherwise, I'd imagine it's doable? What did you end up going with?

I live in Gran Canaria and will be installing this in my Airbnb villa. This means that I myself am not on site and can monitor. I will set a timer so that the pump only circulates water when the sun is up. But as there is a lot of sun on Gran Canaria, the water will quite quickly reach over 30 degrees. Is there any gadget that can automatically turn off the power to the pump when the water is 30 degrees.

Great job. I just completed 80 % of 1 i am making. I didnt make it as big as my yard wont allow that. But i am going to make 2 smaller ones each with 200 hundred feet of irrigation tubing. I was surprised at how easily it kinks to. So i put it on the table next to my project and spun it out. I had to pick it up 3 times to spin it around as well. The stuff is a nightmare. But i am going to add a valve on the feed side of mine to slow the water down. This will give the water more time to absorb the suns energy and come out hotter. I am allso going to use a submersible pump. That way Its independent of the pool filter and much more cost affective. Dont put valve on return side it will pressurize the tubing and cause it to pop. Love your work shop. Are you thinking about selling these ?
