Stovepipe water heater

- Intent here is to utilized the galvanized pipe as means of making the coil. It will not be installed anywhere. Further intent is that the coil should not make any direct contact with the stovepipe, and that there will be an aluminum shield surrounding the outside.
Although I mention heating the domestic water, the primary goal is to transfer heat from the stove location to the radiator that will one day be placed at the coldest end of the house. The system design calls for continous circulation through that radiator with a tap off of it somehwere to feed the existing water heater.
Thank you! Your hours of hard work figuring out the most productive way saved me hours of hard work.
The mistake was the soldering before the coiling of the new pipe. The coupling fitting created a very rigid point to allow a continuous curvature. Next time it will be better to coil the next pipe first then proceed with the soldering. Anyway, if the water heater doesn't work, you have the main contraption for a moonshine distiller. Great video!
Plumber here.
To help you with coiling copper, obviously thinner soft copper is easier.
Alternatively, don’t be afraid to throw some heat on it!
Nice coil. I enjoyed watching this even though I literally handle copper all day at work 😂
I love that old GMC TRUCK! Look at that chrome shine! Looks like a beautiful beast! Wow! Having that on some land in the mountains would make a homestead complete!
Love that you shared your success and failure in this....you just taught this slightly younger buck some good stuff! Thanks for sharing your wisdom Sir!
Just a thought; coil the first line, then start the second -- then trim them where they will connect and solder. It might be easier then trying to solder first and try to prevent the kink.
I think it needed to set off that pipe anyway to keep from getting so hot it might re flow the solder on that union, what's it hold primed is my question and how much it weighed
I love your truck. It reminds me of my dad's old truck. Old blue was a good old truck and hauled many cords of wood in it's day. Several years ago he finally got rid of old blue. I hope who ever he gave it to enjoys it and makes as many memories in it as we did.
Great video! Just a suggestion here ; you should start the bending on the second coil before sautering it to avoid kinking.
This is a very neat idea. You could probably put a wider pipe to cover the coil to get even better heat transfer to your water, or leaving it open will probably help draw more heat from the stovepipe into the room. On top of all that, you've also got yourself a very large, highly conductive coil which could possibly generate some electricity if you run a magnet along the sides. If the center pipe is iron or steel, you could apply an electric current to the coil to generate a magnetic force in the pipe for whatever purpose.
WOW!!!!! I thought of doing this a couple of months ago and now you just made my life so much easier!!! Thanks!
Tip for you, first fill the pipe with sand before you bend it. Great channel Thanks for sharing!
+Burl Nicholson YES
I was thinking the same thing. Or, fill it with water and freeze it.
+Burl Nicholson .....The kinking problem was caused because of the inability of the connector to bend. otherwise he would have almost no problems conforming that tubing around an 8 inch pipe.
Allen Ray you can also freeze water in the pipe before bending to keep it from kinking.
You can't realistically fill that amount of coiled pipe with sand and get it compact enough to prevent kinks this only works with short ish pipes where you can use gravity and "tap" the sand into the pipe and as for freezing water, how the hell do you plan to do that? maybe if you live in the arctic. The way to join two coils with out removing them from a pipe is simple: You bend the first coil as far as you can then cut back so its all coil no straight bits and fit a connector, then you start a second coil, once you have a couple of turns on the stove pipe you again cut off the first straight part then loosen off the second coil a bit push it up to the first coil and rotate it round the stove pipe into the connector. OR If you don't care what the coil looks like: Wind on the first coil, then wind on a second coil in the opposite direction then join the two ends with a return bend connector.
The point is moot anyway as according to the description the finished coil will not be touching the actual stove pipe so he should have just made two separate coils and joined them later off the pipe.
I am plumber in Canada and I have made one of these for a customer of mine, to get a good roll on the copper we used a roll of tar paper as form and laid it down on a flat surface and it worked like a rolling pin, the weight of the roll helped and there was two of us rolling. I made the same joint that you did but with the heavy roll it blended in quite well.
A word of caution, this system must have a PRESSURE RELIEF VALVE! (sorry to shout) if it is a closed system. Simple and cheap 30psi. 240F same as on smaller boilers. Also an expansion tank is a good idea.
The system I made was for in floor heating.
I like your style good video!
How large of an expansion tank?
Hey, you almost got it right, at least you got your head in the right direction. I made one like this and had some problems with it, which lead me to understand the secrets to correcting it. Using one single 3/4" copper tube allows too much flow which is greater than your heating process, meaning you only get a few gallons of really hot water and the fresh makeup supply cools it back down and leaves you waiting.
The correction is to use three 3/8" copper tubes alternating them side-by-side so that none have time to cool out faster than you can heat them. Another problem is heat warping over time, so you want to wrap them tight and also brass braze (not solder) them in about three places from side to side as you go around the entire bundle, to keep them together and close to the stove pipe. You might as well upgrade your tin snap-lock vent pipe to the solid heavy duty steel pipe so it doesn't burn through and wreck your expensive copper. At both ends where the three 3/8 tubes come around, join them through fittings soldered with Sil-Flos a high temp stick brazing rod, so they don't overheat and come unsoldered, where they go in your manifold fittings. It is also best to feed the fresh water in from the bottom, with a check valve because the heating process without a tank will force pressure back to your supply, and heating from bottom up works better.
Great idea and assembly video. 2 points to consider... 1. When copper pipe directly touches galvanized steel it will induce a dielectric corrosion process. This will cause a rapid corrosion process. 2. If you will wind your copper on both sets of coils before sweating them, you will reduce the kinking. When you sweat copper, it reduces the temper and makes it prone to kinking.
I would suggest wrapping your copper around a pipe 1/2" l - 1" larger than the intended vent size, slide it off and then insert short strips of non-conductive material between the copper tubing and the standpipe. This would eliminate any dielectric process.
can also fill pipe with sand to prevent kinking
Good video!
I would like to see the follow-up video and how well it worked for you, and/or any unforeseen troubles you may have experienced along the way.
If he's anything like me, he got ADHD and moved onto aquascaping, bird house crafting, and who knows what else over the past few years. It's probably still sitting on the saw horses he made it on, lol.
This was a great instructional,
I've talked to a number of people with wood stoves in homes / camping wood stoves about doing this.
I think I'll just do it after I get my portable stove built.
thank you for posting it.
You may already know this, but I'll say it anyway. Copper work hardens. To anneal the copper (anneal means to soften the material by normalising the crystal grain structure) you simply heat it to about cherry heat and allow it to cool slowly in air. You will find that the copper much softer to work after this process. Remember, as you deform it, you will harden it. If it gets too hard you can anneal it again to soften it as often as you need. Great video. Thanks.
+Phillip Harris actually phillip , you heat it to cherry red then rapidly cool it, exzactly the opposite of iron. this works with most nonferrous metals (brass, silver, bronze and copper).if nonferrous materials cool slowly they harden up quite a bit. since reading down I saw a few suggesting "annealing" by slow cooling, get a piece of 14 gauge house wire and heat it to cherry red and let it cool slowly(as suggested) it'll stiffen up a lot, then heat again and quench it, it'll soften up, the proof as they say is in the pudding.
Hi Orvarg. I am surprised. I was under the impression that any effectively pure metal eg iron or copper, will not be effected by quenching because of the lack of alloying elements to make use of. The rate of quench therefore, should not affect the final hardness and strength. I will try the copper wire test to satisfy my curiosity, but I am basing my understanding on what I studied and have done experimentally at college. I would expect copper based alloys like bronze and brass to have different outcomes on the rate of quench due to their alloying contents, but not commercially pure copper grades used in water/gas pipes and electrical wire.
+Phillip Harris my understanding comes from experience as a smith making colonial type kitchen implements in these materials. when working with copper (say for a ladle bowl) it will work harden, in order to not have the bowl crack under a dishing hammer I have to reheat it then quench it to remove the work hardening from the piece.( and you are correct in that alloying does make a difference in how a piece hardens( hence the various alloys of steel that either oil harden or air harden)
This was the first video i saw of Elderlyiron i would love to see the finished product.
Twisting an adjustable wrench around any kinked metal tubing will get it back round. A trick I learned from local water company installing a compression fitting splice. Saved me more than once with bending brake lines and copper tubing. Just dial the wrench down on a straight section and spiral it around from one end of the kink to the other. Gets it almost perfect again, as long as it's not creased to bad.
You, sir, are brilliant, and I can' thank you enough. I messed up my first attempt to bend copper pipe for my mountain "hillbilly" hot tub. I have some old stove piping and am going to try this. I knew You Tube would save me
To avoid flattening of the pipe during this winding process you should fill it first with a dry sand. This will minimize the risk or even eliminate it completely :-)
This is how they make brass instruments as well. Great tip!
You are absolutely right filling the inner gap with dry winnowed sand prevents flatting the tube while bending 🌹🌹🌹
Thought it was amazing the first time I tried that
He said he likes it flat because that's more surface area to grab more heat.
seems to me if you throw a 10 inch stovepipe over top to trap heat and it will make a better exchanger. love this video
just wrap in in some good house insulation tape it and it should do the same for less dollars
Great idea and method! Thanks for sharing your knowledge and for being specific on ways to get around obstacles! Great video!
Thank you very much, for your wonderful idea; I love it. May I suggest that instead of a 2 by 4 wood stud for supporting the pipe, that you get a smooth dry tree log, slightly of smaller diameter than the pipe. I think it would make bending of the copper tubing much easier and efficient. I hope it helps. GOD bless y'all.
I'm definitely doing this for my tiny home, thank you!
Thanks IRon, I love how hard you work on things, hi Barney 👋🏻
You remind me of my dad. Hard work, smart work = great job. You seem very innovative. I would like to try this. Thank you for the video. It was very helpful. Just what I was looking for. Thanks again.
That's awesome. As an ex machinist (never an ex machinist that's sacrilegious) now a thermal engineer I can say that's great.
I decided to do the same in my cabin except I ran the same two lengths of copper tube in parallel to avoid that soldered connection. Same total length as yours in the end. Kinda' like a double start thread. I also put an insulated sheet metal shroud around the coil to contain all of the thermal energy at that point. It works very well; a little too well as I have to dump some of the heateed water at times so I am working on a radiator that will help to heat the cabin rather than dump the hot water. NOTE: An amendment to this is that I checked the inside of the pipe after one season and very little noticeable creosote build-up at the coil portion of the vent pipe interior.
Thanks, Ian. The whole concept here is to make the coil diameter large enough to not make contact with the pipe directly. After that, aluminum sheet enclosing the coil, as aluminum reflects 98% of all radiant heat. The heated water was to flow across the attic space and down the wall to a radiator under the kitchen sink, as that's the coldest spot i the house. (north east corner) From there it's plumbed through the crawl space back to the stove. A 2 gallon reservoir was to be placed in the attic just before the drop. With an open top, it would act as a vent and an expansion tank. My theory was that it would passively circulate as long as i could get the inlet temp back to ambient, and my wife wouldn't have cold feet anymore!
@@ElderlyIron Yes. All very good and of course momma cannot ever have cold feets.
When I first saw the video I was concerned about conduction at the contact point of the copper to the vent pipe. But I realized there would be very little contact and hence no cooling of vent gases. there is some contact in mine but the gases are kept hot enough to vapourize the carbon build which attempts to build up. Good qualtiy and properly seasoned hardwood is key as well.
I have considered building an underground hopper to hold a 5 year supply of anthracite coal with an auger to supply my boiler on demand. It does actually burn clean. At least cleaner than wood and is cheap and easy. But then, who doesn't like a wood fire?!
I forgot to add. I want the hopper underground because I can call in a larger hopper truck to simply park and dump. the location is a high spot so no water to contaminate the coal.
It´s a great idea, but you did not realize it. Everybody wants to see the thing working like an off-grid wonder of the world.
What he was making was a giant tesla coil. I was hoping he'd hook electricity to it.
Dang, I felt for you when you put that kink into it. All those perfect bends and then an instant bottleneck.
Form and Function great video. Also in my opinion it really adds depth and beauty to an otherwise basic stove pipe.
110 % for effort, really glad you use the old 3/4" dia pipe, we've gone soft and use 22mm yuck. Greetings from Cornwall.
Great video, thank you, I may use this with my new home made woodburner. Just a thought, could you made the join in the tube using a 135 or 90 degree coupling? Of course the join would stick out but could look neat if done well and could avoid the kinking. Nice work anyway. I've built my own stoves for a long time and have put a lot of thought into them. Good wishes, John
When I bought my old house, it had an old coal furnace. Next to the furnace was the oil-fired water heater. I'm not sure who did it, but someone ran a heavy pipe (probably steel) out the bottom of the water heater, up & into the back of the fire box about 10 to 12 inches deep, made the turn with 2 90's and back out, then the pipe went back into the water heater thru the top. Whenever I'd have a fire going, natural hot & cold currents would constantly circulate the water thru the pipe & water heater. There was a problem though - whenever the water would get too hot, the pressure release valve on the water heater would pop and release quite a bit of hot water. Fortunately, the other side of the basement was dirt floor so I hooked up a plastic pipe to the valve so when it would pop, it would drain over to the dirt side. It would only happen when it was very cold outside & I'd have the fire really hot. Be careful though, because the water that came out of the spigots was so damn hot the steam would roll across the ceiling and I could've probably cooked pasta in the sink. haha
What was needed on the output of the overly hot water heater was a Tempering Valve. A Tempering Valve has a cold water line hooked to it and it adds just enough cold water to it to make the hot water come out at whatever you set the temperature on the valve.
Rustaholic777 Could've used that info 10 years ago. haha
Daniel Heller
I have only known that for the last 35 years or more.
One of my sweet wife's uncles bought a house that had a wood stove in the basement that had a hot water line running through it. Upstairs at the sink Aunt Peggy showed me the steam that would come out of the faucet every time she opened it. I told them about the tempering valve and they sure were happy. I do believe that was 36 years ago.
You my dear sir are playing with fire! The pop off valve is to work that way but only in an emergency with a run away water heater! The reason the pop off valve was invented and installed on water heaters in the first place was because water heaters use to not have them and pressure would build and rupture the tank and all that water wanted to turn to steam and it would literally blow up a house and kill everyone inside! You had better remove that pipe so you may live longer! Just giving you sound advice from a scientist/engineer!
in nz they do this to heat there water . they run a pipe to the roof . if it over heats water just pushes out and runs down the roof to th ground . like a vent for your drains . simple and cool . it just coiled once or twin the back corner .
Thank you for your time and idea....sharing the world we live in...blessingsss......from Spain....
Great job bending the cooper, and thanks for that demonstration , excellent demonstrations .
Someone may have mentioned this in the comments but to help prevent it from kinking use sugar and fill the copper tube and crimp the ends . When you are done wrapping it cut off the crimped ends ,throw it in the tub and pour boiling water on it and and it will dissolve the sugar . Sand is cheapest but I find it doesn't always come out as easy as you would like it .. Salt works too and that can be a pain in the ass also .
125 ft of rolled copper
Filled w sugar
Hmmmm
No
@J thats how they make brass wind instruments (trumpets)
Sand works good, but not just any sand. Use the same 80 grit that a sheet rock finisher will use for skip trowel.
Thanks for the vid, gave me some ideas. As far as all the negative "engineers" who don't know how to actually accomplish anything with their own hands or know his intentions or means....well...your opinions mean absolutely nothing :) As long as we still have people like this guy in the vid, maybe America still has a chance.
This is a old application but very successful, love this guys video's keep up the good work
Bet it worked. Anything to get heat from one place to another. Put it where you need it. Good job Kid!
That trick with the Tee to unkink the pipe was worth watching. I seriously needed to know that.
There are three types of copper. Type M, L and K. Type K is primarily used for underground and depending on where you live is readily available. Type L and K can both be purchased in a soft copper roll. When bending the tubing around a cylinder, sometimes it’s better to use a 45 degree fitting instead of a coupling depending on the radius of the cylinder.
good idea using the 45 degree fitting
They also make 22.5 degree fittings, if you're coiling around a larger cylinder.
Don’t forget type Q, or the curly type!
Largest evaporation tube ever, for a moonshine still, but we'll just say its for making hot water to cut down on the bills (wink-wink).
Condenser coil.
Having built many stills we use a water jacket system. Much, much cheaper
Wow, good exercise and some warm water in the future! Thanks for the video!
I absolutely love you! This was informative and much appreciated! Thank you for sharing your hard earned experience with us!
"Now that it's gettin on to headin toward winter..."
Reminds me of a southern boy I knew who'd say "it's fixin to gettin on toward being almost lunchtime." Which meant about 11:55.
"lunchtime" from a southern boy?....suspect...11:55?....nah
It finna be dinna
That looks like a condenser for a moonshine still.
my family home had one of these when i was very young. that water was so damn hot all the time. worked insanely well.
Would be a good idea to add a Thermostatic Mixing Valve to this kind of setup.
www.watts.com/resources/references-tools/thermostatic-mixing-valves
i haven't read the comments but to my experience, once you heat a pipe when sodering it becomes weaker on the heated part so is better to roll both pieces before sodering, and using an electrical tube bender makes things easier
If you bend it as close to the ends as you can, then cut off the unbendable end 4" bits you can avoid the big fight with the join by having it already uniformly bent first
They have a tool for that. In a pinch you could use a conduit bender.
m Hoppe don't know that that would work radius on a 3/4 emt bender is 8 inches so that would only take him down to a 16 inch internal diameter.

OMG it was painful watching him slide that pvc T around and around 50 ft just to unkink pipe. im a refrigeration tech for 25 yrs now. the absolute best way to remove kink from any size any schedule copper stick or tubing is with 1 tool. thats right any size, schedule, and type and only 1 tool. that tool is in every single mans box and it's a south carolina socket set (10 inch adjustable wrench) put the wrench at a good part of pipe and adj to fit pipe. then dont change wrench size and put it on flat part of kink and rotate back and forth. move left and right thru kink as you rotate back and forth. keep doing this til the wrench will do a 360 around pipe. you sir now have a round pipe again...your welcome. btw, i did thos same exact thing to my shop 15 yrs ago for free hot water to wash up with. 15 yrs later, its still going strong and free. still no water heater in shop and dont need one. never had a problem with copper breakdown, never a leak, never a rusted flue pipe. all my pipe is 24 yrs old. no difference in ash or creosote buildup inside from before to after inventing my little free water heater. and no difference in how stove temp heats or cools down. its really just free use of a waste product. i even have a fan blowing across my pipe and copper to spread the heat across shop. it makes the shop warmer much faster. i clean it out every other yr and maybe get half of a 5 gallon bucket of ash...now thats efficient and thats also using your noggin.

Michael Collins thanks for the wrench Tip. How many gallons of water and approximate temperature could you get in a set up like this guy put together approximately? Thank you from the sand hills of North Carolina
Great idea and looks better than an old stove pipe as well. Hook up a solar panel, water pump? Showing the output temperature would be a plus. Blessings!
i am an engineer and made one of these myself about 7 years ago for hot water in my claw foot tub during the winter months in michigan.(didn't think to make a video) here's the trick:
acquire a heavy-ish spring approximately a foot long that closely fits over the copper and slides along it easily but not too loosely. you can then bend away without the possibility of kinking. just be sure that all bending occurs within the spring itself and not beyond its ends. slide it along as you go. at the end portion where you will join pieces together, don't be concerned with the very end being bent(it's next to impossible to get the very end to cooperate). pick a spot back up the copper at the nearest point from the end where the coil is bent to the conforming diameter and cut with a copper tubing cutter. perfectly curved ends. with the same principle and a larger spring, you can also bend the coupling piece over a mandrel to match the curve of the pieces to be joined, providing a very nice finished look. this only increases the cost by the amount of money it takes to get whatever springs you can find. VOILA...good luck boys and happy bending
Freeze water in the coil then bend it. Remains circular.
too cool haha... I subb'd at "Where'd my hammer go?"... I been there!
Thanks for showing us how to wrap copper pipe around a rare galvanized stove-pipe.
I love this idea. I am a mechanical contractor and the only advice is instead of a hammer use a pair of pliers to take out kinks.....Great Idea!
That's a cool, old , truck, they go forever n ever.
What year/model is that? I love it!
@Brock Main3 I hear that....ok....n thanx for responding.
They are super hard to come bye
Yees i now right.
They make these bending springs for copper tube. They prevent kinks altogether.
And how are you gonna get it trough the pipe, and when you're bending how do you know where the spring is?
@@lukie4ever it goes on the outside of the pipe
Thats going to look great in your house. Copper has such a nice look to it as it ages.
Love your un-kinking method, not to mention your truck, of course. That's a great idea, might just be perfect for giving a bit of Winter warmth to my bathroom, so thanks, and keep on truckin' man.
Ive wanted to do something like this for my barn. Not to have hot water in my sinks or anything but to pump through the concrete floors and have heated floors in the winter.
chefdan87 look into pex floor heat if you mean to encase the pipe in concrete
This guy heats! What a great idea !
Did the water pump through the floor for heat? This is exactly what I want to do for a small cottage. I'd love to see\hear ideas of how this would work?
I know a guy who did that in his garage, as soon as the water froze all his underfloor heating pipes burst. You can't use water if there is a risk of freezing..
@@ydnark83 Most radiant floor systems recommend using a propylene glycol solution. Or run of the mill antifreeze like you would run in you car. That way you don't have to worry about it freezing if you don't heat round the clock.
Chemical reaction from copper to galvanized pipe, small pin holes will form in the copper
Maybe a thin layer of silicone sprayed or some heat resistant painting on the stovepipe will prevent that....something like Thurmalox f.e. www.dampney.com/Product-Line/AT/ViewType/PTID/23
Ryan P in 6 years it has not happened yet to mine
If you had a wood lathe you could do that on low speed on the lathe. Anchor the start point, don't bother to reform the copper from pancake to loose-coil, pass the outer end of the pancake onto a former (can be wood you've lathed down to shape) and pass the copper tube from the pancake through that white plastic 'T' you have and showed us (anchor it to the lathe tool post) and with slow speed you will wind that soft copper onto the former. (former as in a shape that something else is being formed to). But, looking at the end result of what you did, I'd say that a professional job couldn't be better. Absolute marvel you are. And, I'm going to make one of these. Thanks for show us all here. 7.531 million views, well done lad!
Nice idea. One way to stop kinks when bending copper like that is to fill it with sand before bending. Works great.
kinks can be taken out easily with an adjustable wrench, start at a good section and set the size of the wrench, then slowly work back and forth towards the kink and you'll be almost round again!
Good tip.
The reason it linked is because he overheated the copper when he soldered it can just tell he’s not too good at soldering (I’m a plumber) best way to fix a kink is to squeeze the pipe in a flaring block
Thanks
What a clever man, thanks for sharing. God bless you.
this guy is very generous with technics. i love this video
could've used a 45 instead of straight coupling
unless you're using a thermosiphon, any sharp bends are bad news!
Isn't filling the pipe w/ sand or ice use to bend pipe like that, eliminating the kinking problem??
sand can be hard to removed sometimes. salt works like magic.
For anyone else who makes one of these, using this method, you can get a much smaller hump in the tubing, (where the connector is), by using a 45% joint instead of a straight joint.
Cool project. I've muddled over how to do this myself (on a rocket stove in fact, I see some commenters mentioning them :) )but the way my house is set up it would be a Nightmare with a capital N. I have a stem wall at the midway point of my foundation and the water heater/rocket stove are at opposite ends of the house...and it's a log home to boot.
I could do it just for the sake of catching that extra heat and storing it to radiate inside the house, though. I would definitely need a pressure relief system.
hey there, it's my second comment on this video. you know how your connector caused a humpback at the joint, right? i just thought of something that might help your vertical humpback gap problem from soldering in the straight connector. if you use 2 of 45 degree elbows but make sure to solder then slightly off tangent to the copper pipe you should get much less copper pipe rise height off the stove pipe surface but at the expense of a temporary gap in the coils along the stovepipe surface. hope that my terminology is correct and that you understand and that my concept is correct ;) i am not saying my idea is more efficient or better or anything like that....just saying it might lessen the humpback in the copper and allow for a slightly larger diameter pipe to slide over your copper and act as a jacket to trap more heat and to cover the copper to make it look as if it is not even there. ps... someone else mentioned that you might want to consider using high temp solder which you probably already did use ;) and another idea i just thought of is a pressure relief valve if it is a closed hot water system :) i really love your video
Might be able to mount a thermometer at the hump?
Here is a trick that will work alot better. If temos are below freezing kink one end then fill with water, let it freeze over night and whamo it bends like a charm without altering copper pipe shape. Good luck!
i hear filling it with sand, capped on both ends, serves the same purpose.
As a 25 + years as well driller I've seen many a frozen pipe, open ended or not and all they did was freeze and split the copper!
Yea it will do that at times but not all the time. If a person does not have a bender this is an alternative.
I've heard but not tried using fine fish tank sand in the pipe will let it bend how ever you want it to bend. But what the ----- do I know. GL.
John King
I think the basic idea is to have some type of pressure from the inside of the pipe, whether it be water or sand, or whatever. I have my concerns about ice though, had to many busted pipes in winter.
Great Vid. To prevent kinking it might be better to use a 3/4" socket forming tool to join the two pipes.
Awesome video I’m pretty sure you’re the guy that sold me my blue Chevy truck. The light blue square body.
When joining another length of copper tube, cut the strait end of the coil off and cut the strait piece off the second coil then join them together.. Now no kink in the coil.;
FOR ANYONE WANTING TO KNOW HOW THIS WORKS....cold water goes in top or bottom, out to hot water heater, and back into house...basically its heating the water, as it goes into hot water heater, so all the heater has to do is keep the water at temp, instead of heating it from cold to start..personally id go bottom to top though, as the water gets hot it will help pump itself up and out.
in bottom out top natural circulation heat rises cold sinks.
I'm a old gas man from years ago used it allot they do make a small flexable slinky looking device that slices over Cooper tubing to help you with out crimping the copper comes in all sizes works pretty good !
I have a TARM wood gasification boiler that uses a good lenth of 'finned' copper coil in the water jacket. That transfers heat pretty well and I just circulate that into my domestic hot water tank using a mixing valve.
But reclaiming anything from the stovepipe is a great idea. You'd think the manufacturers of double-wall stove would haave thought about lining them with tubing by now ...
how did this end up working bud? did yas get er finished?
My guess is that solder joint popped a leak the first time he heated it up. Stove pipe temperatures run around 450-550F, solder melts (depending on type) between 350-425F.
Solder will only melt with no water; try to solder a joint with water in it- you can't get it hot enough to melt unless all the water is out.
@@eugenepearson4467 - It's not that copper soldered joints won't melt with water, it's that along with the copper itself, water often can act as an effective heat sink and dissipate the heat from a single torch (even w/ MAP) elsewhere relatively quickly. Now, what if, under pressure, the water superheats to 425F? The solder will melt and open joints. Here's some documentation from the Copper Development Association that states 250ºF is the maximum temperature for soldered joints (Brazing the joint would be the proper joining method): www.copper.org/applications/plumbing/techcorner/cu_tube_steam_systems.html
@@eugenepearson4467 Do NOT put a torch on a pipe with water in it. Not unless you like flying shrapnel. Water expands, turns to steam, expands more, BOOM. Less than enjoyable rest of day.
@@paulchilders9969 We can't tell from this but I'd assume that there was a pressure release safety valve in the system anyway.
Cool, but it does rob the heat for drafting properly. Especially conductive is copper and any other metal which conducts electricity well.
Check.

Then ground the pipe
Steve, electricity and heat are apples and oranges. That said, I think I get what you were talking about initially. I think you were wondering if too much heat was being lost into the copper, which might slow down the exhaust air simply because it would be cooler, and therefore not rise as fast. If that's what you meant, it would not be a problem, because this type of heat scavenging would likely be so little that the air rising up the stack would still be plenty hot and keep the firebox breathing just fine.
One thing to consider, though, is that the copper might keep that section of pipe cool enough that smoke and creosote could condense out onto the inner wall, building up enough to be a problem and a fire danger if it got thick enough to ignite and cause a chimney fire.
An easier way to fix copper tubing that is out of round is to use a Crescent wrench. Open it up not quite as wide as the widest part of the oval, put on the tubing and start working the wrench back and forth like you are freeing a rusted nut as you work your way over the oval. Tighten the jaws a little and do it over until round. After you've done this a couple times it is fast and easy to do. Hope I explained it well enough to help someone out in the future.
what if you soldered a 22.5 angle in to connect them 2 coils together to make the curve on the stovepipe
I love it, but what about the dissimilar metals? The electrolysis between the gal and the copper?
I thought this video was about how to build a device that produces green copper salts over an extended period of time.
Get some playground sand, it's a lot finer, fill the tube with sand before you roll it it will keep it shape.
Still seems like it would take a month to get all the sand out..
good video, i love this idea! when the pipe kinks, try using big pliers or a hammer and dolly from each side to form it back into shape ;)
Been meaning to do something like this with the soft copper and a radiator. Thanks and just subbed.
if u ever want to bend soft copper tubing pack the tubing with sand
Vice grip pliers work well to squeeze the sides of a kink!
Once a pipe kinks you compromise the integrity of the pipe...using pliers to straighten it out, is only making it worse.
8:40 use big crescent wrench jaws to resize it by rotating it little by little, but once it's kinked it's pretty much done. Next time before you solder it get the radius done first, then resize it round with a crescent wrench just to fit the coupling & then solder it, You'll just have that short area at the coupling straight that you can't help. Just hide that around the rear of the vent pipe so you don't see it.
Wow,nice work. looks so tired of doing it But I so excited see the results !
Looks like a good way to make a still lol
Randall Berry well in effect it is a condenser coil working in reverse
Yup..I also saw a worm happening there. It's got to have a massive flake stand...lol
Wouldn't the heat from the fire melt the solder? Sil fos would be a better because it has a higher melting point than the solder.
If thats a concern 95/5 will do just perfect...
harris 15, buddy
Muchas gracias por lo que enseñas. También muy buena la música y me encanta ese uncle Jesse's accent.
Man you are one tough dude. I would have bought two steel tubes one bigger than the other. I would have the flue gas in smalker one and water jacketing with the bigger tube. Simple! You just increased the price of copper!
THANKS ALOT. GREAT VID
How's your right arm doing?
+Edwin Hernandez I probably couldn't do it again!
By the way that's one cool truck. What year is it?

Subscribe! :-)
LOTS of good uses...Ive wanted to try this for years. Carbon buildup inside the cooled areas of the pipe will need to be cleaned more often, I assume. Thanks for the walk through.
You look and sound like Mr. Kimbal on Green Acres! That's a good thing!
