- DIY Solar Water Heater. The Dual Spiral "black poly pipe" Solar water heater. Easy DIY. simple modular design allows for several to be chained together. very hot water. easy achieves 130F to 140F (with 160 possible). very lightweight. super portable. great for camping, an emergency situation or everyday use. video shows how to connect it to a water tap/garden hose and how to chain the spirals together. *each spiral is 50 feet of 1/4" poly pipe.
I took a 200 foot roll of 1/2" poly tubing and split it into two bundles slung over the roof peak,pumped water up there with a clear water pump from "HF".........I am getting a 5 degree rise in water temp pumping from and back into my jacuzzi and have been using the system for over 20 years. Replace a pump every 5 years beats hell out of a $200/monthbill for running the jacuzzi heater.
What was the flow rate on that?
I’m trying to imagine what 300 feet of 1” black hose might do, but with a faster flow.
A 5 degree rise doesn’t sound like a jacuzzi, it sounds cold.
@@Inmate533 I think/hope he means it rises 5 degrees each time the water goes through.
I'm actually moving to the Philippines and that's an amazing way to heat water except I'm gonna have like 30 coils
How much better was your more recent solar water heaters with the greenhouse box? What is the difference in steady-state temperature increase for the same flow rate? Not the increase in temperature when it's been sitting for some hours without flow...
can i ask, this temperature is keep same degrees continuously same? I mean, after finish water in spiral pipe then water get cold or what? Thank you...
How much less efficient would it be if it was water hoses instead of black poly pipe?
What was the water temp before it went thru the coils?
You could run that tubing around the eve of the roof of your house and put a mist system to cool things down in the evening. ; )
Can you tell us how long the hot water is kept at that temperature, and temperature difference between the spiral with copper pipes and aluminum cans painted black. Thank's
Paint the wood black the hose sits on might help keep the heat in?
this could very easily be portable. Very nice..
Why not go with a larger diameter hose for a greater volume and potentially higher flow rate if desired and regulate with a valve? Also wondering if perhaps a non coil arrangement allows the sun to reach more of the hose Total surface area for even more heat generation.
Larger diameter with greater volume generates less heat. Higher flow rate also allows for less time for the water to absorb the heat. The coil works better as the edges are tight, mutually supporting and insulating heat loss.
I did. 150 metres of 2' Black poly laid across a paddock to a bath --water got way to hot during the day and had to wait till it cooled down.
@@johnmerton3630 in winter or summer
What is the temp of the water entering, or exiting the garden hose. Last time I checked drinking from one of these at 90 outside, the water was pretty hot. especially laying on this peagravel
You call it 'black poly pipe'...so what is it? irrigation tubing?
Polyethylene drip irrigation tubing
How do I attach this to a tank so that it will heat all the water in the tank? One end at the bottom of the tank and the other at the top?
Great idea, love the wooden dowels
I am planning a similar construction for my RV but I want to suction cup the spirals to my windshield. how much does each spiral weigh filled w water? can you plz give me an approximate weight so I can see if my plan is feasable and what size suction cups (how many) I need to order for my project?
I know you asked months ago and have probably got your answer, but he said it was quarter inch hose (assuming that's inner diameter for example) 100 ft long, total volume is .3 gallons*8.5 = 2.5 pounds. Best guess for the weight of the hose is 4 lbs, so your total weight will be around 6.5 lbs plus whatever you mount it to, but your windshield should handle it no problem
can enough of these reach boiling, or would attaching a parabolic trough work best?
hi. if they're not enclosed behind glass it probably wouldn't reach boiling.
Really excellent. Good to understand in case of need.
Need to put a layer of aluminum foil over the board then put glass over the tubing and then caulk around the edges
i think is even better if use aluminium paper on te base to get more heat. Also you can use the aluminium or mirror glass on the four sides, at 45 angle. good job and thanks for share
Thanks for the helpful video! Please let us know what size the plywood board is that each coil is mounted on?
You could put the spirals on your roof with a closed systems that cycles all that hot water through a copper coil heat exchange to be used has a heating element right?
You has sustained water temp of 130F ??
Where did you find 1/4" black poly? The smallest I've seen is 1/2".
looks like the drip irrigation type of pipe
Hey Desertsun02, Love this Idea, I wonder what the flow rate is in ounces at the 130 degree F temp? I had 1500feet Coil of 1/2" id poly tubing like for Drip Irregation. I hooked up to my swimming Pool, But the Flow rate has to be slow enough to get the heat in and everything needs to be insulated to keep the collected heat at the collected temp, the flow rate/volume of water through 1/4" Poly drip irrigation tubing/ hose to maintain 120 to 130 degrees F would be very slow and a long process over Hours, a small Hot water heater tank maybe a 12 gallon size, could be a good Holding tank as they are insulated pretty well with Rock Wool insulation, so after few hours you may be able to accumulate enough water for a quicky RV style show, that means NO running water, get yourself wet, turn it off suds up then rinse with conservation being the primary goal, it could work in an emergency, keeping in mind it only works on clear sunny days, overcast or cloudy days solar is almost or is Useless, But Clear days Solar is Awesome I have a out Door Solar Kitchen That I cook on Everyday that is Clear or I can at least see my shadow
those 1/4" coils in insulated boxes 1" to 2" thick Foam wall Insulation from Home depot/home improvement in the back and walls of the box then a plastic lid with a secondary Clear plastic Insulating bearier for the top would maximize the heat in and reduce the Heat Loss
How good would this be for a treehouse water heater
Ok I like this, now tell me how to use this during the winter and it not freeze? Thanks
or in a window inside.
1/4" tube is small but effective
what if i built that inside the solar air heater,would i still get hot water in the middle of winter inn Michigan?
Bah! Just drive to Flint and use their services! Vote Democrat, Michigan...it has helped your state so much.
how do i store the water for evening
Have you ever considered living off-grid for a week or two using your inventions for conveniences? You could bring some food and use your portable stoves to cook. You would have to bring your own water supply and use this tubing if you wanted to take a quick warm shower.
Yea...that sounds fun...
I was planning 3/4 inch black irrigation tubing 500 feet. Was trying to calculate the sustained raise in water temp....
Hey there - I was wondering if you did this? I'v been considering a 3/4" tube instead of 1/2" because I have 3/4" PVC running water I can plumb into.

Better to use 2half inch pipes it’s all about surface area.
The exterior area of a half inch pipe v the interior capacity.
The problem being that a 1/2 in pipe is approx 1.5 around dependent on thickness of walls while a 3/4 in pipe is around 2.5 inches around which means less surface area for capacity and capacity is much larger than twice as much so heat exchange would be less.
Same as a 5ft bale of hay struggles to feed 20 cows but a 6 foot one has twice as much feed and less waste due to lower surface to area
That is not a Thermosiphon, you are using the pressure from the hose to move the water. This is just a solar water heater.
Coool! Is that water line for an evap cooler?
More coils when the sunlight is less than optimal? Glass panels to increase the heat in chilly weather?
I was thinking something similar (glass panels). Make a box with a glass top, paint flat back inside for even more heat.
@@sunriseshell Yes. But I was going to use perspex. Everything else will be spraypainted black.
@@jeffreydemaree2683 difficult to justify cost and Perspex will yellow and become brittle nowadays beware of hail better to simply heat more water and store it inside or underground with some cheap insulation such as dry sand with plastic Barrier dry sand doesn’t retain heat.I’m talking house roof garage shed roof
Family have heated pools for years this way flow upwards on roof with small enough pump to not boil the water
I’ve seen irrigation pump pipes melt if not started to cool the pipe in hottest weather
So how do you implement this into your pool system?
Brilliant, like all of your stuff.
Very Nice Job !
What was the starting temp?
hi there. not measured - but i'd guess about 80F
Thumbs up ! .... ..... ...... ENJOY....THE SIMPLE LIFE
Where can I buy the pipe?
What's the flow rate?
love it 👍
I would think.Buy a the cheapest criculating pump hooked to a gfi of course and use the pool water?No
Easiest way for sure.
pretty cool
Couldn't you achieve same temp with just one coil slightly larger coil ?
Well I did that for my pool with 800 ft of house and it got so hot that I might have introduced alge to the pool
Hi, i like the design. Very simple as things are ment to be. I think that most heat comes from the acceleration of the water molecules into the enclosing spiral adding more friction and speed in eavry loop. I would recomend making the center more tight before exiting the spiral. Plus you could somehow focus and increase the heat at the center of the artifact.
Keep the exploration going! i will definetely dare to build one some day soon. Thanks for inspiration.
No! This absolutely incorrect! The water picks up heat from the sun's radiation on the black pipe. Insulating the board and placing a metal sheet that is painted black under the pipe will increase the thermal area for collection. Additionally, glazing the entire unit will increase the warming effect on the water significantly.
Where on earth do you get the idea friction supplies the heat! I'm in shock.
very good .....
I am. making something. same. and run the water to a R R water heater ( 50gal) then to my house water heater. The idea is to preheat the water prior going to my regular house water heater.
Hi, can you share ho you use this design to preheat the water for home gyser. I am trying to reduce utility bills by preheating the water. Thanks
Huge loss of velocity and pressure
*had
Nice. But why only 1/4"??
Surface area/water ratio.
