Great concept..but plastic pipe.. getting heated.. would leach dangerous chemicals into the water! Better use copper...and a insulated stainless steel tank to collect the hot water. Hugely more expensive..but you will save on futre medical bills!!
We heat our above ground pool this way. We have all the black flexible irrigation pipe/tubing mounted on our garage roof. But we do use a water pump to circulate it from the pool to the roof heating coils/tubing. And we are located in Western Canada. We have had it now for about 8 years, works great.
It would be more efficient if use three or four battery heaters coils and store the output hot wáter in an isolated tank for use in home installations.
I'm considering doing something similar with an acrylic or plexiglass (whichever doesn't yellow in the sun) layer between the black collector hose and a chrome colored undersurface So the sunshine that shines between the loops bounces back up to hit the pipe from the underside.
@@epeh4213 i second this. ask chatgpt to come up with the equation for the parabola, then plot it with a tape measure. say your half circle is 12 inches wide, radius 6, then you can have the focus at 0,0, one point at -6,0 another at +6,0, in this case the directrix is at -6 and the parabola goes through 0,-3, or halfway. if you want the focus deeper, you can go as deep as 0,-4.5 in which case the parabola goes through 0,-6, but you still have to plot it in between -6,0; 0,-6; and 0,+6. So you can set the focus from 0,0 to 0,-4.5, and the parabola minimum point will be between 0,-3 and 0,-6. If you set the focus at 0,0 there is the advantage that you can have a fixed central rod that does not need flexible connections and can be welded in place, and only pivot the mirror, and the outer circle can have a continuous contact gear drive, while the parabola minimum would be halfway through the wood, plotted.
If you can rise the temperature to 100 C and it's possible by the way ,then you can use these free energy to desalination of sea water and saving the planet and the humanity 💚 I'm totally proud of you man
and it would be better if the inlet of the reflector had a larger opening ... the garden hose is not really UV-stable in the long term, it should be replaced by a UV stable one
Very good! Cheap to build and effective. For Europe or North America only works for maybe 7 months. Awesome for cabin or camping! Drain into a giant thermos and youd have tons of hot water
You must run the pipe back into the water tank to circulate by convection when not in use because now you are only heating the water which is in the pipe which is not much. Nevertheless great job 👍👊👌🙂
Further improvements can be made by painting the outside black and pumping the water around true the pipes and into the barrel again, then all water will become hot. That is to say, if the barrel is isolated on the outside with very thick polystyrene and is painted black.
@@robinhooper7702 You do not need an electric pump to circulate the water, it can be done with wind or solar panels or even by convection, warm water is lighter then cold water. A Sterling engine could be used, that runs on heat (from sunlight).
@@robinhooper7702 if you put the tank higher than the collector and set the pipes correctly then the heated water will flow into the tank because it is lighter and ciruclate the water with no pump. look up thermosiphon

you should run the water from the valve back to the tank and it will heat all the water doing it the way you have will cause the water inside the reflector to continue to heat till it boils and scald you and only supply you a small amount of water. I also built one use copper tubing vertical and sat it over a small fire just to heat washing water that could be lifted of the fire when sufficient hot water was made using the same lay out that you have used here
Always 👏 people applying themselves, maybe try a copper metal coil instead, better conductor of heat.. or possibly a glass coil to receive sun light.. Hope and wish you results..
If the mirror was a parabolic curve with the pipe at the focal point it would be capturing much more of the suns heat. As it is a lot of the sunlight hitting the mirror is reflected straight out and wasted. It might melt your hose though!
I was wondering about this. A parabolic curve would be better for catching everything, but the coiled hose is quite large in diameter. Maybe there isn't a huge difference if a true focal point is not required.
@@JohnKruse ideally you'd see the image of the pipe smeared across the entire surface of the mirror, that means all light rays entering it are hitting the pipe. There's one frame in the video where he stands in the middle (7:51), and the reflection of the pipe covers about 2 thirds of the mirror. So I think if he aligns it directly with the sun, at best he's getting 2 thirds of the potential sunlight.
Try adding additional turns of tubing, and external additional relectors aimed at same coil.Cover glass with coating for reduced re-radiation in the outward direction might help to contain the heat.
Although, I have 3 solar kettles (500ml each) which if I put them out in the garden in sunlight, will warm quite nicely. Takes about 3 hours to boil on a sunny day. Rain spoils the effect. In high summer I can boil 3 times in a day. Work from about late march to late october .Im in UK in SE
No there is no heat in the uk sun even on a hot sunny day , compare that with an overcast day in Cyprus, in ukyou need hitech , high efficiency setups to do any good
We built something similar (a pool heater) for my son's pool. We raised the temperature on average by nine degrees every 24 hours for three days before it stopped rising.
Connect your outlet pipe back to the drum. Ideally use the heater with some uphill slope and connect the higher end at a higher level in your tank and the lower tank connection to the lower heater connection, this should give you thermo siphon flow so you heat the whole tank. You can still tee in an outlet at same point or take another connection direct from the drum bottom
Very interesting, although, are you sure that your "pipe" is at the exact 'focus' for the sun rays? Did you measure it? It doesn't seem so. You have a concave mirror surface that reflects the sun rays at an exact height in the middle of your apparatus. You have to calculate this height to put your tubing where there is the concentration of the rays....because you can get temps much higher.
Nice. Paint the Wood, it will rot fast when the Rain hits it and make a whole that rain can go out. I would use a black Container then blue but good Idea !
This is a marvellous idea. It's easy, cheap an reliant. You can easy heat up the water collected by a canister from the rainfall on your roof going down the drain pipe. I even have a quite cheap proposal for upgrading the system. The idea of using a glass sheet to get internal reflection and thus a higher yield of thermal energy is great. But if you would coat the tube in prior with a black color, which is IR reflectant, the tube would heat up even more, since less light from the VIS range is reflected (1. Loss) and less thermal radiation is emitted from the tube (2.Loss). In theory you should be able to boil the water. If this doesn't work yet, one could easily scale the system, so that the tube length is doubled, so more thermal energy is flowing into the water passing through the pipe. Unfortunately I wasn't able finding a simple shop where you can buy such a color yet. But many research paper state that it's actually possible and I even found a company who fabricates such pigments for making IR reflectant colors. The (i think) most promising Pigment should be (FeMn)2O3, which is actually also quite common in nature. Good Luck and keep up the good work.
@@desiideascreativity I further recognized that you're using circular end plates for your design. I calculated it through with Excel and you're actually loosing 30 % of thermal yield. Better would be to use a parabolic shape of the end plates. I can send you the Excel Sheet if you like for simulation purposes of your design. Best Remarks Dr.Ing. Matthias Rost.
The whole point of parabolic reflector is to concentrate energy on a point. Maybe video distorts dimensions but it seems pipe is way to close to back wall (not at focal point). Most of the light bouncing off reflector is just shooting right back out without hitting hose.
Don't need perfect focus for this. Energy needs to be distributed over an area, and a spherical reflector works at a greater range of angles and doesn't need to track the sun.
What do you think has been traditionally used to move water around houses etc ? What a strange question. I assume you're ''relatively'' young ? Well anyway the answer is yes.

Would it be the same if I cut a barrel in half and put the foil paper? What is the coil you used made of? The only thing I have questions about is when the hot water was coming out why didn't someone hold the camera for you so can could see where the hot water was coming from?
Would rather want to know the temp in the storage unit. Considering heat rises, mayHap the colder water will constantly sink to the copper coils Replacing the heated water? My tropical home.. near boils the un-insulated house water pipe that runs in the roof cavity and stays hot well into the night in summer :/ (tin/metal roof)
A very Indian way of doing things. If the half pipe is only used for shape and to be covered by a reflector, you could as easily have cut a barrel in half. The MDF will fail pretty quickly and the foil-imoregnated plastic wrap you have as the reflector layer will, too. The plastic tubing will perish rapidly in UV. Use copper pipe, coiled inside and in contact with heavy steel pipe, ideally filled with concrete. Use a stable metal like stainless steel or see if you can rig up a home chromoly bath to plate your barrel. These won't rust and will keep a good sheen for a long time, but will still need cleaning. Or simply use aluminium foil. This is a reasonable kludge on a budget, but unnecessarily complicated with the making of the half pipe.
In fact, why bother with the reflector at all? Simply lay the hose flat in a coil and place it under a black steel plate. Reticulate this using a thermosiphon and increase the reservoir. Better still, do it as a double coil heat exchanger: one coil collecting heat, another dumping it inside your hot water system, which can be pressurised and plumbed to the home.
I did this at summer camp years ago with a garden water hose coiled on a piece of corrugated metal roofing. The cooler water dropped down into the coil, and the heated water flowed out the top of the hose back into the tank. Then we painted the hose and backing a nice black color to increase the temp. We made it up above 100 degrees F. A couple of kids and a hose. No electronics. Why don't houses have a hookup like this? Some real engineer or even plumber should be able to come up with a real and workable water heater/ preheated like this.
Another thing, heat rises that’s why tanks are always in the loft as that’s the hottest point so he should have a container at the bottom connected to the container at the top and that way the water would get hotter, as the water warms it would heat the top container/ highist point and as it cools it would flow back to the bottom container/ lowest point then the cycle would keep repeating and the water would keep flowing naturally so there would be no stagnant water
Wonderful! Warm water when the sun shines. Meaning not in the morning when i need it for showering or in the evening when washing dishes or whatever. It is right available when i am at work and not at home. Another green energy solution wich is completly useless for nearby everybody.
Great concept..but plastic pipe.. getting heated.. would leach dangerous chemicals into the water! Better use copper...and a insulated stainless steel tank to collect the hot water.

Would work a lot better if the reflector barrel was parabolic.
A lotta' heat not even being focused!
The target is not a point, so it's okay if the image of the sun is spread out a little. That mirror shape is close to parabolic
Yeah, parabolic side wall shape would probably get it to boil the water for better hygiene.
Very true. The pipe has not been placed at the focal point of the reflector.
and it would be better if the inlet of the reflector had a larger opening ... the garden hose is not really UV-stable in the long term, it should be replaced by a UV stable one

To make it more efficient you need a parabolic mirror and not a half round. Also: A copper pipe is a by magnitudes better heat conductor.
Your reflector is round, thats not perfectly focused. It needs to be parabolic (flatten out the curve a little towards the edges)
Surely make sure max flow rate by ensuring entry/exit of pipe in not restricted then throttle down if needed.. Maybe micro comp control🤔
A good basic idea 95% of people could probably manage it ........ until you switched on the welder when it dropped to below 5%

If the half pipe is only used for shape and to be covered by a reflector, you could as easily have cut a barrel in half. The MDF will fail pretty quickly and the foil-imoregnated plastic wrap you have as the reflector layer will, too. The plastic tubing will perish rapidly in UV.
