In a way this stove reminds me of a common finnish stove for home heating though it is not a rocket stove. Instead of air exchangers, the sides, back and front are filled with heavy concrete slabs that the flue gasses warm up before exiting. That gives a different form of heating, slows down the release of the heat for longer. Don't get rapid heating of a cold workshop like that of course, but easier to keep the temperature consistent in a home that way.
That's awesome! Really appreciate your videos, simple and clear without all the tech speak and maths. Since watching part 2 of this build and trying2hards rocket stoves Ive gone ahead and started ordering some bits for my first attempt. Looking to build a stainless rocket cooker with vortex. I said to myself I wasn't going to get involved in this stuff but hey...you make it look so fun. Great video and cant wait for the next instalment.
Stephen Owens Thanks Stephen, think you will enjoy building the cooker just get the airflow and exhaust flow right and you cant go too far wrong. Cheers.
I love your humility! We all make oversights and have to make adjustments, you are just showing you are human :) I think you have done an amazing job!! Your design is sound I believe and your fabrication work is quite good!! Wishing You the Best!! how is it working now? Liked !! Subbed !!
Pins and needles! Very exciting. Second year heating the house with my own build. Can not wait to start the third build. Happy welding! Merry Christmas! Cheers!
Interesting build. Just one point, I think it might be wise to spring load the bolts holding the riser band to allow for the different rates of expansion and contraction. I'd hate to see that casting crack. Cheers.
James Lamb Cheers James, dont worry the band wont be so tight that it causes damage, it should expand slightly when heated anyway end contract again when cool.
I think you've got a great set up going on there b'y!! Lots of thinkin gone into her. I'll be watchin an waitin for the next part? Merry Christmas to You an ur Family!!!
Would you know if putting a inconel grate coated in platinum change the orange flame to blue flame without being used up just like an automobile catalytic converter ??? Thanks Loz
Looking good, cant wait to see the run and temperatures. When completely assembled, can you let us know what it weighs as wellplease, Looks like a beast, in a good way Happy holidays and Happy Hogmany Cheers Madd Macc
Madd Macc Thanks Macc, Its a heavy lump for sure will have to guesstimate at 90 lbs for the firebox, 100lbs on the exchanger without the riser ! All the best to you.
Joe Bis Thanks Joe, I wanted to see just how much heat this size would pump out I know it will more than cover my shop, i will just say that its an early production model for now. Cheers.
Marcel Lenormand Thanks Marcel, believe me there are plenty of other ideas I would like to incorporate into this stove some of them come to me while I am building and some are planned, I usually just want to get the thing finished then wish I had incorporated them when its finished. ahh well keeps you keen to make another .
Marcel Lenormand I will be covering front and back of firebox and the sloping sections at the bottom with both firebrick and kiln shelf to protect them and retain heat inside, should be blistering hot in there with the addition of the preheated air, I think alot of gassification will be happening inside this one when up to temp, thats when the sec air will come into play as I slow the burn down.
Super! This prompts another question which has been bouncing round my head for a while … how do we ensure that it gets enough secondary air for complete combustion? I'm guessing there's no such thing as too much in this regard.
Does the vortex make a difference? It looks really cool on video but, does it make the stove work better? I like the looks of rocket stoves, and have seen a lot of variations. Mine wold be portable, so I could take it from place to place, and just hook it up to any available chimney or mass heater system.
tom drew It gives a cleaner burn much faster tom and mixes the gasses better inside the riser, especially when you add secondary air. good luck if you go ahead with the build.
Have you thought of going into manufacturing the risers commercially? It looks like you could get a concrete manufacturer to mass produce these? Just a thought.
What's your feelings on the internal heat exchange tubes running vertically inside the heat exchanger? Were you able to determine any advantage to distraction in having those there?
Pickleballcl They were a bit experimental to see what happened, but they do put out alot of heat being 3 times bigger than the corresponding area on the exchanger I would fit many more were I to build another like this, the air convection inside pumps the heat out.
What is that square tube for the heat exchanger called? It is the first time I have seen that style and I would love to use it for a project with a more decorative touch as well.
That is nice. Love the transfer unit. Some of the things you were saying about secondary air have just helped me out with my build.
Thanks Dave.
Southpaw Davey Thanks Dave.

Excellent build so far, can't wait for the fire up. Good job.
Thank you for thinking outside of the " barrel".
The band holding the riser is a great idea. That's two great bands coming out of Liverpool. Cheers
Bob Vance Thanks Bob, I was never a fan of the other Band though lol
***** Lol

Al Ryzy All the best mate.
I thing you are doing a wonderful job. Look forward to more updates.
TheEmptynester Thankyou.
Can't wait to see this thing running.
Merry Christmas to you & yours.....
1timbyCheers mate, Im looking forward to it as well, must not rush the finishing now just so I can light it.

No idea mate
@@LozHarrop Thanks Loz for your honest answer.
Coming along nicely!! Merry Christmas and Happy New Year!!
kbbacon Cheers Kev, All the best to you mate....Hey what you having for christmas dinner.
Probably turkey and ham with all the trimmings.
great job can't wait to see it in action
electricdick Thanks, im counting the seconds too mate.
Looking good, cant wait to see the run and temperatures.
When completely assembled, can you let us know what it weighs as wellplease,
Looks like a beast, in a good way
Happy holidays and Happy Hogmany

You're a super-smart guy. I've learned a ton from watching your videos.
Thanks Donny
I like the final cast, with the wupdedo.
+ValiantVision Thank you.
(this not vortex,
'accelerator', turbinator... spiral as spring,
vortex has several blades, twist gaz,
see air vortex CNC cooler)
Where do you get this "refractory" stuff......I'm not a welder so would like to use this stuff to do a small "experimental" build.
castree kiln do online orders thats where i get mine
That's coming on great mate.
Jason Bentley Thanks Jason.
Looks like a nice clean burn that to mate
great job mate that is going to be a nice stove just might run you out of the shop Lol I'll be watching for next vid Love it!
Joe Bis Thanks Joe, I wanted to see just how much heat this size would pump out I know it will more than cover my shop, i will just say that its an early production model for now. Cheers.

I like it! some ingenious ideas gets my Squirrel cage spinning
Looking splendid! Well done.
Quite industrial as you say.
Are you getting carried away at times once you get the welder in your hand!? ;)

Hehe. I'm looking forward to you giving the casting a proper burn, particularly to see how insulative it is.
What do you think to casting part of the firebox too? Where primary combustion is taking place.
Marcel Lenormand I will be covering front and back of firebox and the sloping sections at the bottom with both firebrick and kiln shelf to protect them and retain heat inside, should be blistering hot in there with the addition of the preheated air, I think alot of gassification will be happening inside this one when up to temp, thats when the sec air will come into play as I slow the burn down.

powerliftingWALLAU thankyou.
very clever idea
John Canivan Thank you John.

+richardpinell Hi Richard, I dont know if they have a name, I called them heat convectors due to the way they work. Cheers.
Nice
super
Have you given recipe for casting or hsnve i just missed it would. Like to find good cheap one .what i am putting my core in is large. Thanks
Mark Vaughn Hi Mark, part 1 of this stove build shows the mixture I used, you could bulk it out with grog. cheers.
Forgot to ask...any concern with dielectric deterioration with stainless and copper?
Pickleballcl Nothing so far.
ANOTHER BLOCKBUSTER
MERRY XMASS
ROBERT AITKEN Merry crimbo to you Robert, thanks for watching.
By the way, what size is the burn box? And the diameter of the riser tube?
jimmytk riser is 6.5 inches wide inside. firebox is 11x11 inch x 14 inch will give all dimensions at the end of the videos. Cheers.
WHAT diam is the evacuation thnks
