Whenever bending copper if you want it not to flatten, fill it with a median like sand. After is full of sand seal off each end, then wrap, then cut the seal and blow out the sand.

the world need more people like you and your lady!

thanks Kris. Me and my pooch, Eustace, appreciate your time, effort, and high standards.

From working with copper in jewelry, i learned that if you are wrapping copper tubing, fill it with sand. it is less likely to buckle on you and it'll allow enough room for the liquid in this to flow freely

I have a friend who has a hot water furnace. He has it connected to his hot water heater. During the winter, he said that the relief valve goes off every now and then because it gets so hot. Put a vessel under it and you will be fine. Just keep it full of water to keep the cycle going. Your doing great, Mate.

Everything is looking great. Can't wait to see the bath area. Thanks for sharing. Blessings

Love the explanation and noises describing how the water will go through the coils and heat up, made me lol 😂, very Rawley Birkin QC from the fast show 😂😂😂

Love this Kris! I'm learning loads from you and from the comments section. Thanks! Your going to have such a lovely time living there :)

P.S. you probably already know this but the creosote(smoke) hits the single wall stovepipe and forms much quicker than if it was a triple stainless. Soooo, now that you've made that stretch of pipe even colder... more creosote will form. Just something to be aware of. Running a circular pipe cleaning brush down it, maybe twice a winter, will prevent chimney fires, which are very dangerous(personal experience). thanks again.

Done the same only i filled the coil with water and froze it in the deep freeze. Worked great to prevent kinks. Enjoying the free showers. Great video cheers from Canada.

My wife and I love your videos, and just caught up. We look forward to seeing what is to come! We are really impressed by your ingenuity - and we hope to do something like this ourselves in a few years. Thanks for the inspiration!

Love love your cabin. Can't wait for next video.

love the videos and the round house . well done !!

Wow, that looks awesome!

That is a fantastic/brilliant idea! Looks great too! I'm anxious to see how it works once you get it up and running!

I did this today. Later i saw your video on th me same task. I cant blieve you were able to dk this with out kinking it. My first attempt at a turn was automatic kink. In the end i put the pipe the lake. Underwater i crimped it. So the pipe was full of water. Then i coiled it. Water cannot compess. For those out there trying to do this. Thanks kris

Proper stuff bud, great job 🖒

Even tho it flattened out it looks amazing, actually like you said it gets more surface area. As usual great video brother

Great video! If you put the tank a bit higher you will increase the flow and therefore heat transfer. Because now the highest point is a part of the pipe where the hot water is forced to go down. It works, but the flow is slower. The higher the tank the faster the flow. A perfect situation would be if the tank inlet would go in at the top from the side. Anyway, keep on doing what you doing ;)

Great job mate see ya in the next video !!

beautiful work. pipe looks fine to me. slightly flattened like that allows for much more contact area rather than the small contact area of a round pipe.

Good show I once had a similar system, I used a circulating pump to help with the flow of hot water

Awesome! You should give us a tour vid soon! Well done, I enjoy each video.

Really cool but quite a workout!! Love your vids.

I remember with the old fireplace on a former home, the ash-collection pan in the back needed to be cleaned every week....Admittedly, is was bigger shove, but still. Hope you back's getting better.

Well Done!

Such a shame to have to cover it up. That copper wrap is absolutely beautiful and goes so well with the look of the cabin. Great job, great videos.

You are an inspiration

Well it looks cool

Looks proper tidy that mate well done.

trick is to fill the copper with water. let it freeze then bend it around the stack. won't flatten out like that. leave then ends open though so it don't split. looks good though.

You did a beautiful job wrap the copper around that pipe. I would definitely wrap the copper pipe with Insulation

I like your vids!

wrap it in rock wool ... then sheet that in copper ... then you get the insulation and the copper look on the pipe as well

The coil looks great. The slight flattening will probably make it more efficient as it will have more surface contact with the flue. I think it would have been murder to try bend it on your own if your have filled it with a material to keep it round. Good job!

It's a giant tea kettle, lol. A whistle would be cool eh.

oh no kris ! now I have another subscription on youtube, ev's are right up my alley, im currently tinkering with 18650 cells. looking fwd to binging on your other channel.

this is nice idea

i remember bending copper pipe around to make a way to cool my wort off making beer... you should get a home brew system going on in your off grid life!

You have done a good job. You will need to wrap the copper pipes in a terminal rap. This will make a massive difference.

great vids been with your channel for a while.

I'm glad i went to the end of the video to see that; once again, we have an unfinished project cliffhanger.

You need a chimney brush. Go up occasionally (every two weeks) brush the flue. put a bucket under the pipe to catch the ash.

I also heard you can use frozen water in pipe. To keep round.😅

super build ,you could have filled the pipe with dry sand or water then put stop ends on with when you bent it round pipe. don't think you've lost any internal space even though it's a little flat . excellent

Excellent top man

Nice job!! Just be careful hot water and pressure. But I'm sure you will safe!! Keep up with the good work

very nice tight wrap should work fine for ya.

nice

Art.

Brilliant, phenolic or foil rockfall lagging would work. the coil wrapped flat is far better than being round... look at a Viessmann hex... For expansion I assume your going open vented? Solar prv and vessel would be perfect for this Now working out a design... thats for the inspiration 🙌

For all the sand comments , imagine how long it would take to fill that coil of pipe and he has increased th3 surface area of his pipe and slowed down the flow of water which makes it a perfect exchanger .

Awesome,Car/Motorbike exhaust wrap may look good and insulate,..id try without first as the copper looks noce! :))

Better seasoned wood would give you less sooting. Great vids. Looking forward to the next one.

you can also anneal it with heat before wrapping and it will bend easier.

what was the diameter of the copper pipe? what was the grade of the soft copper?

Great job wrapping the copper! it really is a shame you have to cover it up, it looks awesome!

a lil' tsp(trisodiumphosphate),in the fire coals,every once in a while will help with that creasote build up-hang a chain in the flu--you can slap it against the inside of the flu/like ringing a bell,..it will knock the dried creasote off the sides..just a lil time saver tip.....cool build man--i love it,the guys below are correct about,the copper tubing..those are ol' moonshiner tricks(and all they had was hard copper ,my great aunt sally ,used to use sand-lay copper in a long bed of coals,then rap around a stump..jda

When you build your earth ship a small wood stove is all you need combined with solar hat water panels. Get a chimney temperature gage if you are not used to running a wood stove it will help you keep it at the best combustion zone.

Kris" you need to place a shield in back of that stove!!!! After all that work you did to build that home, .... the stove uIs to close to the sink and the log wall!please think about putting a shield back there!!!!! Also, buy a flexible cloths dryer vent cleaning kit to run up the pipe to keep it clean!!!!! God bless!!!!

To increase the siphon effect, the coil should be as low as possible compare to the water tank. Since hot water wanna rise, if the tank is the highest point, the siphon won't work.

Don’t forget to sweep ya chimney. 😉

This is really good stuff! Been waiting to see if someone would do an in depth video about this kind of setup. Curious whether you could run push a small alternator from the water pressure in the line with a pump impeller in-line.

How can someone so smart work so hard?? Next time use a hand torch and heat the coppwr tube

Wow that copper looks really great. Too bad if you have to insulate over it.

That’s an amazing technique

Fill tubing full of sand and solder caps on the ends then roll bend it it wont collapse then.

You can also mount a old hot water tank on back of stove it will do two things Heat water plus add extra hear to your Home

fill the copper pipe with sand. cork it. wrap it. no kinks.

amazing watching you put all this together, Did you purchase the land? and do you plan on continuing making videos of your work?

I think what I would do is have larger pipe in an enclosure round the chimney pipe, that way the pipe is kept hot but the water is still warmed in the enclosure, then I would just pump that to some radiators (with an expansion tank). Hot water I would boil on top of the stove.

Looking at that flue, you need a Rocket Mass heater !

so i was wondering what you have used as insulation in or under the flooring? i remember you spoke about it in the beginning of this adventure but i havent seen anything been made. i my self is thinking of a similary build but cause i live in sweden and have a colder climate during wintertime i have a bigger problem with handling the cold, iknow that you britts generally have very cold floors but still. best regards Markus

I see guis fill it with water and freze it so it wount kink. but I think that the flat pipe will work better.

Si hubieras rellenado el tubo de arena de playa, lo hubieras podido doblar sin aplastarlo, manteniendo casi intacto el diametro del tubo.

did you do a part two, to show the rest of the design working out?

Good job. You should have put sand in the cooper pipe, then you could have bent it and it would have kept it's shape. I think.

Kris! How's this performed after 4 years!?

Pack copper pipe with sand before will stop pipe collapsing

just spotted the air filter on the garden tractor, +10 hp lol!

Now wrap it with insulation it will heat water much quicker 👍

Hi Kris, What size is that copper pipe? Great video.

to thermosyphon the tank has to be well above the heater coil.

idk if flat is what you were going for but if you need to bend any pipe - fill it with sand and cap the ends and it can't flatten out that much when you bend it

Saw another gent he put an 8 inch pipe around the copper pipe so that you would get the cooler air from the floor and exaust the heat up high heating more air he used a 90 degree off the stove went up with the 8 inch around the copper then atached the 6 inch to the pipe going though the roof .

I saw you're 'why off grid' video and you mentioned you watched a documentary that talked about the money system - was that the zeitgeist? And have you seen zeitgeist - addendum, the second movie? It focuses more on how to fix things, especially towards the end and I think it might inspire your project. Btw I think what you're doing is absolutely awesome.

your problem with slow water heat up, the old time plumbers used to fit up to 1 inch pipes to promote flow and nice gentle slopes plus no dips to create air locks. try findiing Granada tv series by brian trueman house of the future he stiffend his windmill pale with 2 cables from top to bottom with 2 ropes from pole just like bow and arrow this stoped the whip A fascinating programme

Bet you got that pipe cleaned out pretty good, what with all that rolling on the pole! :)

It is easy to say after you have done it, but you should have had some play pit sand, dried it in the oven then fill the tube to make it solid and then it will not flatten or kink.

What size is the copper pipe that you used? I plan on doing this with my wood cook stove.

You are doing a great job mate, not sure if its a right suggestion, as you might would have thought about it already. The tank would be better stacked up against the wall to the similar height where the hot water inlet pipe is, for a better flow in the kitchen sink and the tub I guess, instead it being on top of the work top which will provide more free room. And for insulation i would think of some kind of a glass box sort of thing to maintain the look of copper coil going around.

if you left the copper tube uninsulated nothing bad would happen. also probably this works with no pump, hot water raises naturally... i consider same for my sauna hot tube. there could be helpfull reverse thermostat so if chimney is cold, no water gets cooled...

I have a feeling this will lower your flue temperature further, so you might have to run a really hot fire (dry, well seasoned wood) to help prevent the creosote buildup. Not sure what species you have available to burn in Wales, I'm from Northern Ontario, Canada, but here hard maple is the premium stove wood, cut one year burn the next, Oak has the same BTU but requires to years of being split and piled and covered to properly season. Aspen/poplar burn really clean but only has about 60% of the BTU's of hard Maple and oak, it is better with a 2 year drying time as well. Beech is very good as well. Birch is awful for creosote, plugs the chimney in no time, split if fine and burn hot! Best of luck, can't wait to see how well this works!! Keep up the hard work.

great vid bro. is the next video out? i'd like to see how it all went :)

What diameter tubing did you use? Thank you

Chris, a pipe bending break is not an expensive tool. I believe they come in several sizes for the pipe you need to bend. No kinks, nonlesks.

Love your videos! But what did you do to that chimney? How could it clog up like that? Firewood needs to be dry or you stink up the whole neighbourhood with PM2.5 particles.

maybe before you finish the plumbing connections just put a pail of water with a piece of hose going to the pipe and run the stove to test it

Did you think about using sand in the pipe to stop it from kinking ? The only difficult part is making sure it is dry so it will flow out easy I have done it with success. also small stove use the hardest wood you can find Oak, Hickory, ect they won't ash up as much..You have done Great, I admire what you have done..

Doesnt the contact of copper and iron makes iron to rott?
