damn tubing is like twice as expensive now

What pump dis you use?

In what month you put them in the grond. I would like to try but now it's juni, so tis is already to late???

Honest question. Do you think two circular coils has more capability than one large "race track" oval pattern? I haven't tried to run the numbers because Im sure someone already has

What did you do for filtration???

Some great ideas on how to take our rocket launcher to the next level, thank you! 🚀

Could I pay for the ability to use the stl file to print my own for my truck? I can send $10 just for ability to use file

Great job using Sketchup first, I do the same with all my projects.

I am sure it works for a few minutes, but there is no way that after the initial hot water is forced out of the tube that the sun can heat the cold water coming in fast enough for this to warm a pool.

How many of the brackets you used for the plastic sheet?

I wanna see the pump you are using. I saw another video and the guy throws a sump pump in the bottom of the pool. I think the pump would be a tripping and entanglement hazard, so I'd like to have pump outside with only the lines going in the pool. nice video. Looks like a fun project with your son and it's awesome the things you are teaching him.

love the video, i like to know what kind of water pump did you use to adjust the water flow?

How big is the pool the is heater is heating?

0:32 i hate ripping small pieces like this on my table saw. It almost always gets stuck and kicks back out at me 😳

The most impressive part to me was 2:30 the actual coiling of the tubing. However I don't want plastic being circulated in my water supply. Heat and plastic are an infamously bad combination. Doesn't really matter what kind it is. If it's on the market, it's going to degrade and leech in sunlight. Not just chemicals but microplastics. I've seen other builds using copper tubing, which must be a massive price hike but would be a safe alternative. This is a wonderful concept that can be modified in countless ways.

Great video. Very detailed. Beautiful mountains. 🤝

What pump is he using?

Are you able to stop and lock the cover part way? So instead of fully closing the cover, if you wanted to have it close only half way or with only 3” from closing completely, can you stop it at any position? And will it safely lock in place if you were to leave the vehicle?

Wow that $50 dollar heater 3 years later is $750 lmao

Just so those watching are aware... PVC is not a good choice for pressurized air. I see these air rockets popping up all over the place and it is only a matter of time before one of them explodes shooting PVC shrapnel everywhere. It is against code for plumbers to use pressurized air in any PVC system because PVC has two annoying properties. First is that it has a brittle fracture failure mode, so it explodes when it fails and second is that it degrades substantially over time, particularly when in the sun. So fresh PVC can hold a lot of pressure, but how do you know what the condition of they system is and when it will fail? I have seen warnings for these rockets popping up where they say to wrap the PVC in tape. I have no idea if this actual works or make it worse. I would love it if someone did exactly what you did, but instead of PVC, used a material that is rated to use with compressed air. It doesn't need to be as strong; it just needs to have a ductile failure mode so it will just leak instead of explode.

I actually really enjoyed this video and I am going to share this with my friends and my not so friends.. n I'm sure they all will enjoy ... thanks n God bless

I've watched several of these videos why don't people just measure the temperature in pool before and after dont think these work that good 20000 gallon pools maybe couple degrees more efficiently put on roof shingles or metal but think trying to heat a 15.000 gallon water heater with hose pipe laying in sun it would work good on smaller pool kiddies pool

Ahh...an Intel chip!

Did he ever use this is parallel or just in series???

You need to be cautious about the extreme temperature and chemistry and also having stopped the flow without draining the system.i believe the max structural strength of the tubing degrades as temperature increases. You are going to go through more chemicals, the more stable the temperature the more stable your chemistry will be. Think higher velocity and continuous flow during daylight hours or draining the system when temperature is achieved.a simple vacuum breaker and three way valve should do it.

What pump were you using to run the two 1/2" coils? I have a 9x20 Intex with a small sand filter pump... Im not thinking you recommend hooking them together? Am I thinking right that I should run the separately ? Please advise... And Ty

Great idea and design. Would like some info on the pump and hookup.

if you would set that up by your fence and then also have mirrors on your fence so the sun bounces off and onto your heater, it would increase the temperature! Also as the water flows through, it captures heat energy. As long as the water doesn't reach the point where it's at the max temperature before it goes to the pool then thats okay. if it reaches max temp 3/4 through, then the last 1/4 of the system is doing nothing. Nice idea though. I wondered... if under the pipes, you'd have Styrofoam painted black, if that would be better. Now. The black tubes and wood are heating up by being black, that heat is transferring through the wood and escaping. If there is Styrofoam then it would heat the black paint and radiate back into that open space and not being sent into that wood. I could be wrong but I think it would possibly work better (higher temperature).

The sound was horrible. I could hardly hear you, which would have been nice if you could have spoken louder.

Cost of wood is currently very harsh. DIY to make up the difference

You know this was a good initial concept a few years back. But with what today's products are and options I decided to opt for a tankless 8 gallon electric water heater and water transfer pump. Keep in mind the cost difference was only $100 more to go fully electric instead of solar materials needed for the project. The interesting thing is is I now get up to 150° on demand whenever needed however I still have yet to see what the electric bill is. I had to go with the electric heater just because I never know what the weather is going to be and overcasting scenarios. I like the convenience of getting hot water on demand. Me watching these videos allowed me to uncover my new 2.0 electric water heater process and after an hour of installation it works flawlessly. I'm not saying it's for everybody but do your own research.

Don't cover the collector. It's a myth! For pool collectors where the pool water is about the same or typically lower than the roof temperature, such glazing insulation will actually prevent warm roof air from transferring to the pipes, but secondly about 10-15% of sunlight is reflected back into space by the surface of any glazing material. So you lose that much straight off the bat and then there are the potential overheating issues. Keep it simple don't glaze it, you'll get a better result.

Nice video filled with good tips & trix. I'm setting up a solar powered pool heater right now and my goal is 30°C / 86°F in the pool. I'm starting with 250 meters / 820 feet of 20 mm / ¾ inch PEM hose in a flat rooftop setup. A 20V rainwater barrel pump (2,000 liters - 528 gallons / hour) will be connected directly to a solar panel, so it's a completely automatic system controlled and powered by the sun. No sun = no pump = no heating. Since I'm located at 60° latitude in the northern hemisphere, I'll guess it'll be some problems and math to solve along the way, but it'll be fun. Keep up your good work

How much did it heat the pool water up? Not at end of inlet, but overall.

Great video! Thank you!

The wall with the widow bottom plate is rotten 2x4 should have been replaced. Even it was stamped for stud it can be used. I would not us it. Still did a good job.

Can be not grown direct to soil?

Hello. Thanks for the video. Question: on the video the cut list is different from the attached via GitHub - Wood Plywood Knots. Can you double check? Because I'm trying to build by your docs and see some strange dimensions. For example: *A* part is a dresser side and written 1 feet and 3 inch BUT the internal drawer has a length of 1 feet 4 1/2 inch which bigger than side. Maybe I'me mistaken but I'm using your files. Do you have 3-d model with attached A,B,C,D parts with explanation? Thanks a lot.

FYI your Z track is upside down.

Great video. You explained everything. Others just assume that you know certain things. Thank you. Most informative video I’ve seen.

Seems to me that in the test, the output was basically air temperature.

Those are not 45's they are 90's

Do you have plans for this ? I built one already but not motorized so i'm really interesed in building a versions like this amazing one.. thanks

That worked so well! Love the video. Thanks for sharing

A lot of fun for all with the project. The mechanical designed parachute deployment thing works like a charm!

i have learned quit alot on this video, thank you ! i have a tip for you, out side screws you can round out wih drill bit and cant be unscrewed !

I followed as soon as I read your page’s name 😂

I love your name-DIWY-it's exactly what I've told so many contractors, "I could've done that!" Thanks for the video and explanations.

Hello which program do you use for build this house? thanks you :_)
