DIY wood stove. Is A Double Barrel Stove The Best At Heating?
HTML-код
- Опубликовано: 5 сен 2024
- Spent some time getting the double barrel stove made and all hooked up. Winter is coming quick so it was nice to get this project done so we have heat in the shop for the winter. The double barrel stove with the heat exchanger puts out a ton of heat! Definitely more then the old blaze king did.

Not the greatest
Nice build! No negative criticism here whatsoever. Just FYI, if you connect a pipe end to one of the bungs (opened) and put the other pipe end outside you'll increase your stove's efficiency exponentially. Your particular stove is probably plenty warm enough because of its size and heat exchanger feature, but burning outside air is also a key feature to maximizing heat gain. By burning outside air the room has a positive pressure and therefore air pushes out of the space. When the stove burns air from inside the same space, that space has a negative pressure and subsequently colder air from outside is drawn in through the cracks. Like I said though with your particular stove you'll be in a t-shirt during a polar vortex if you have the fuel and motivation.
These are the type of millennials the world needs! This is the same stuff i did @ there age! I started working at a Junk yard stripping junk cars and getting parts for customers, @ age 14 i was driving a car all around the massive yard and using a blowtorch to heat up stubborn axle nuts and cutting off quarter panels for $50 a day cash, i loved it!
Heck yea!
Grab a Honeywell fan and limit switch from the hardware store. When it gets hot enough it'll kick the fan on automatically as long as it stays hot. It would also help to make sure the exhaust gasses stay hot enough to ensure proper draft
I have used this same kit. Got it from Tractor Supply about 15 years ago. Used it to heat a 40'x100' garage with 25' tall ceiling. It took about took hours on a snowy day to get the shop to the point of where I was working in a t-shirt. Always had it glowing red with a blower from an old furnace to move the air around it. Got end cuts and slabs from my local saw mill that was firewood grade. Over all. I can not complain about it.
Awesome to hear!
Man, it would have been way easier if you just used the plastic barrels.
🤔
You can't use a plastic barrel for burning
@@lewiszellner3357 yes....I know.....that was the joke....
Way hotter too.
Ha ha
Removable heads on the barrels are worth buying. The top barrel, especially, can't be cleaned out without disassembling the stove and after a few years fly ash will cover and insulate maybe a quarter of the top barrel's surface.
Nice work fellows.But if you want to get more heat insulate the whole bottom barrel.Have you heard of aircete?
I built a few to figure that out.And use aircrete to make your own insulated pipe too,everything works better.
The idea is keep you combustion chamber hotter thus turning more of the wood into heat and then taking
that heat off the top barrel(large air to air heat exchanger).This way you can always run the stove at temperatures
that would normally melt the uninsulated stove down.
Gary, how did you make your own aircete pipes? I’m looking to start a build like this now an considering best upgrades
I built my double barrel crudely and quickly in probably 40 minutes because it was cold outside. Used only a power saw with a metal blade on it. There's a lot of advantages and disadvantages to them.
Advantages: The top barrel makes a great food warmer, food stays hot for hours if you set it on the top. The tail of the fire goes through the second barrel, which is much safer, you don't want your stove pipe to turn red. You probably get more than 20% more heat. You can cook on the first barrel.
Disadvantages: Looks like a boiler room. Top barrel needs to be removed and cleaned after 4 months, it fills up with soot. Maybe you can put a small door on the second barrel.
I think the double barrel is still such a fantastic invention, but your wife might not like it in her living room. It's great for a single man or the garage or side heater. The benefits outweigh the disadvantages.
If the fire is smoking inside when you light it, light a bit of paper and put it through one of the bungs in the top barrel, it works most of the time
Will have to try that out!
A friend of mine used a 4 barrel set up. He cut all his small wood five foot long. He had plenty because he is an arborest. The thing makes an insane amount of heat. It lasted several years.
That's awesome to hear!
I really like the heat exchanger. That is definitely a worthy addition and is something I need to make with my powerarc.
Most definitely!
Just an idea, use a barrel with a band/removable top for the top barrel so you have access to bolts etc
"Are you going to be able to put your wood through the hole?" Y'all are fuckin cracking my shit up!! 😂
Haha was a good time. We never tried it though 🤔
The barrel feet that go between barrels are for wine and whiskey/ wooden barrels that's why they are tapered.
Hmmm interesting 🤔
If anything, it seemed like a fun project to do w/ the fellas and some sodas. Could any imagine the shop humor going around.
For sure!!
Having built several of these stoves as well as worked in a stove building shop here is a tip for more efficiency and heat from your stove . Most stoves have a baffle by moving the pipe connection between the two barrels to half way between the door first rib creates a baffle without building one. This creates a draft that circulates from the front to back and more heat comes off the sides and top of the bottom barrel. It all so burns the wood from front to back and burns longer and more completely to very fine ash. On the top barrel put the outlet in the back because it allows the tubes to absorb and draw off more heat and I have used straight exhaust tubing 2" has worked very well.
Do u have a pic of your heater
Diagram good sir !!!
Link and pictures or diagram please to where we can actually see what you are recommending .
My dad and I had one of these in a four car garage, minus the pipes. We just put a fan blowing between the two barrels. Worked in t-shirts all the time. One time we went into a boats shop to ask for directions. They had one in their huge shop. It had a great big fire "barrel" ( I think they made it out of some big pipe) and then it had six regular barrels between that one and the ceiling. It was nice and warm in there.
That's awesome!
invest in some insulation for your shop!!! it will completely change the way your shop heats and cools!!! if you use the foil backed styrofoam sheets it will also increase your light too!!!
My first shop heater 30 years ago. You'll love this stove.
What was the second?
@@NitroAuto77 , 385 LPG tank turned vertical with heat exchanger. Very heavy and you can't over heat it.
@@pacemetalfab wow! That is some good steel!
you need two big ceiling fans or all your heat going to stay in the top half of the shop trust me on this one been there done that nice shop
We are planning on doing that. Just have not had time to yet
Insulation.
Nice dont forget to put brick on floor and walls only around the the stove and put a hot plate and a water tank out of stainless for hot coffee water if power ever went out you have back up heat cook and drinking water sometimes every thing freezing no water no electricity but you have your heater stove good job
Electric dryer temp switch works great for the blower. Kicks on / off at 120*
Good to know!
In the future remember you can simply tape the bolt to a piece of wire with a lock washer on the bolt and then pass the wire through one of your pipe holes and out a bolt hole ( if that makes sense) . The reason for the lock washer on the bolt is it usually will bite and hold the bolt from turning when you tighten the nut
Most definitely
my little friends ....the yellow jackets came over to see the new stove and one just landed on me and i am pretty sure i just got stung.............hmm i think ? ha, ha!! GREAT shop heater!
haha it was pretty funny! good times
Fire brick on the bottom is a great idea. I’m putting one of these in my shop and definitely going to do the brick. Thanks you 👍
Heck Yea!
The less expensive porous firebrick degrades over time. I used regular patio bricks in my barrel stove and they seem to be holding up fine while still shielding the bottom of the barrel.
A Stanton1966 pavers? I’m very surprised that those worked better. That’s interesting.
I'm not a stove expert and not saying they work better. However, I got a pallet of free pavers from a landscaper. And I figured what the heck? I'm only putting them in a barrel stove. Some people just use sand for a liner.
A Stanton1966 I gotcha 👍. Thanks
Have you thought about adding some copper pipe around the chimney vent? You could use it to heat some hot water for your wash basin and bathroom?
There is already a hot water tank in the shop for the bathroom.
Use a temp switch to control your fan.
That's the plan
Reminds me of a 2 keg stove we for our shop at my dads shop,we used 1 inch stainless steel tubing . Stainless steel is readily available in the south if you work offshore . We don't have the wood down here but we have real short winter.
That's awesome
SS is a TERRIBLE conductor of heat. It's all going out the flu. You'd need a huge heat exchanger, plus if you get it too hot, then you're gonna fuck it up.
Excellent build, I'm not sure I could cut such accurate holes with a torch. I've seen a fuel-oil tank built similarly, I like the idea! Love the Blazer, and it's fantastic to see the flag on the wall. I plan a similar build for my house eventually.
Heck yea! Thanks! 😁
Also, for ease of cleanup of ash, I put two rows of brick long way along the bottom of the barrel then laid my brick on top of that. It gives me a flat surface for much easier ash removal. Awesome job on the stove guys!! Oh...New Subscriber by the way. I like what you're channel has to offer. Zip~
That's a good idea. Hey thanks! Tons more to come! 🤘
Very nice build! After watching your build, I thought up of using a cardboard template and use a punch to mark the centers, then you could take the template to the other side to match up the holes pretty good. Another thing is that angle iron idea, you could just run longer pieces and weld plates for feet and do away with the cast iron legs. I'd cut a door at the bottom, use some 1/2" square 16ga tubing to make runners to place your fire bricks over and reuse the cut piece for a door to easily remove the ash (I hate cleaning out the fireplace...lol). The door wouldn't need to be perfectly sealed for venting. I see that y'all have the chimney going 90°, if that is OK, would running tubing all around the shop walls also help with radiating the heat instead of the top barrel and air tubes + fan? Just a thought for fanless passive radiating heating.
Great build. I’ve had my double barrel stove now for 4 years in my shop, pretty much the same design as yours minus the horizontal tubes in the top barrel.
Nice!!
can u inspect the top barrel? im curious if theys got collectable creosate inside.would be nice on old school wooden fence posts maybe🤔
We had this type of woodstove growing up. This had to have been the hottest stove I have ever seen. Growing up in the cold winters of NH we would literally open the windows in the winter to balance out the temperature at times. Great video.
Perhaps a round of expanded metal could be placed over the front of the tubes to tidy things up and keep people from accidentally burning themselves.
Terrific job and application with the angle iron supports.
In another RUclips video someone added a length of 2” pipe along the bottom from the circular bung hole to the back of the barrel this pipe was capped at the back and perforated via drill to carry combustion air to the back of the barrel for better burning throughout the length of the bottom barrel.
Awesome video, thanks for sharing all the details
So...whats the outside temp, the inside starting temp and the inside warmer temps in 1hr, 2hr, 3hr did you check this? interested to know what you got out of the build
Could you guys build a pizza oven with a barrel and fire bricks. That would be cool to see your concept/ design, or something from scratch. You could also cook most anything with it plus it could heat the shop at 900 degrees
Terrific job and improvisation. Surprised you didn’t add a coat of high temperature paint on the outside. Consider dry stacking cinder blocks in the corner to add fire break and a bit of additional thermal mass.
The paint is coming eventually lol
I wondered if you guys thought about putting a clean out at the front of your bottom barrel? Maybe make a small opening on the bottom side and you could just rake all of the ash to the front and have it drop into a metal bucket... Just wondering if you think that would work.
We have been scooping it out with a shovel. Been working good
Looks like a nice heating stove to me. Going to share this with a friend who has a 40x60. Thanks
Welcome!
You guys bought the wrong kit... That one is obviously for red barrels...
🤣🤣
Thanks for the details, I can get some open top barrels, now I understand why, just need to replace my current dbl barrel stove.
Anytime!
5 gal tank on a shelf with 3/8 copper tube into 1/4 black pipe welded in the center of the bottom drum, you won't hafta pay to get rid of all your waste oil and you won't believe how much heat drip oil puts out.
That is definitely the plan. Hopefully soon we will have it done.
Great design. Nice job. Here’s a thought... how about filling the upper barrel with bricks? That way, the retain and release the heat for a much longer time after the fire burns out.
Bricks? Why not just sand or gravel..and it would fill up all the nooks and crannies. Just leave a channel for the exhaust gases. I like your idea though.
Well, you need chambers for the gasses to escape. And here in Finland, we have these contraflow type fireplaces that retain the heat for 24 hours. I think the sand might choke it out.
Nice job, but I think I would have placed the stove closer to the center of the shop for even heating. Seems like you are going to have a very hot area and a cold area at the other end.
Thats what the fans will help with
@@JustinTBraun Yeah, but by the time the fan pushes the heat to the far side of the shop, it will have risen to the ceiling, leaving a cold area where the people are :)
We have some fans in the ceiling to push the warm air back down. Would be nice to just put a diesel furnace in.
Fabricator: (sees thumbnail) they did good work on that
Not a fabricator: 1:39
Fabricator: well... never mind
Great work guys, gives me an idea for a shop heater for myself.
Oh yea?
It's been 2 years and thinking of this for my 2600 SQ FT shop did it work well?
Is it worth my time?
Intresting idea,but how do you clean the heat exchanger?
Your build was a year ago, how well did your stove heat the garage?
I wanna know aswell
Good video and good information. I wonder if you could turn the top barrel into a masonry like heater if you fill the space between the pipes and the barrel wall with sand. Heat in the sand will release slowly to the room for a long time. Since sand add more weight to the top barrel so you might need to beef up the support more.
So the smaller stove you were using will now go in the opposite corner? Your roof doesn't look very well insulated. Great heat exchanger, probably increased efficiency by a very large margin. Good job.
Still need to get the roof insulated
CUT50 plasma cutter $250 on Amazon it works it’s not a pos I own one it works great. Other guys on RUclips have had there’s for 3+ years and there’s are still going strong
Should have left the fire bricks out for the first burn. Also should have made a small grate for airflow under the wood your burning. I watched a video similar to what you did except he used a fuel oil barrel and had the pipes above the burning wood.
That would have been a good idea.
If you run a long chimney you'll get even more heat from it. That's why you see in pictures of old buildings with the chimney going through them.
Might have to change it around
@@JustinTBraun well see how the current setup works out for you. My not need to put anymore money into it.
The white Chevy in the back ground brings back memories of my 1979 Silverado lifted 7 inch no body lift with 38.5 inch ground hogs.
Heck yea!!
You guys should insulate the building. The heat will just go up and out your garage. Good luck heating the shop too.
Thats the plan for the future.
@@JustinTBraun Good job fella.
👍
Run a small oil line in the front where the air is. Stand back..,thats all you need.
I've sold a ton of drums to make those things
They work good
Have you had any problems with the flue, since it doesn't have much rise to it? It seems like it would be better to go a lot higher up before exiting the side of the building.
I'm sure it rises once through the wall. Has to go up above roof to get a draft. Personally I'd run it NH indoors and get the head from it and exit through the roof but either way works
I saw another video where the author moved the flue 18" above the top barrel. He said it helped a lot.
I got a double barrel wood burner in my garage. Works amazing and I dont have the tubes in my top barrel
Yes they do!
I got mine painted with the black stove paint to. Looks good and works even better
made a double barrel stove out of 30lb propane tanks due to the fact i re-qualify them for a living and thus have an near unlimited supply of them. throws heat like you wouldn't believe. Only problem I have is the smaller fire box runs out rather quick when you pump the shit out of the stove.
That's pretty rad
Have you guys ever used Rivet Nuts, it would make bolting those legs on way easier!!!!
Use them all the time on my vehicle builds. Good stuff for sure
You should put concrete board over the osb.
That's the plan. Hopefully haha
The first thing you should do is to insulate the roof, 8 inch thick insulation atleast. Heat travels upwards and you loose all that heat if the roof is not insulated. With a proper insulated roof you will cut energy loss and could problably heat that garage with a much smaller burner.
It's on the list just no funds to do it yet
Do you have a purchase link for the blower fan and piping used to vent the smoke?
Good job I’m excited to start mine
if you put isolation on the roof, it do much more to keep the heat in AND keep the heat OUT in the summer too.
Thats the plan. He is just saving up
Looks like it should be an efficient stove. I'm wondering though, is there any way to clean it? Won't creosote build up on the heat exchanger? Maybe it doesn't last long enough to worry about.
That is a problem we are having right now.
@@JustinTBraun
You ever find a solution to the creosote buildup? That was a concern I wondered about - there's no way to get inside the heat exchange to clean out the creosote....
I have had a double barrel set up in my 25x30 foot shop for over a decade and recently added a heat reclaimer for the flu that scavenges the exhaust heat as well as the neat from the heat exchanger (top barrel). You should totally check them out. My shop would take about an hour to warm up before hand and now it's 30 minutes to comfortable temps in the coldest of days. I DO need to install pipe into the exchanger on mine though. Cheers! Zip~
I'll have to check that out!
So how has it performed so far? Is it holding up well and do you see anything weakening on it yet? I've wondered how long these things last over time.
might be a good idea to put a small hatch in the bottom of the burn barrel that you can open to scoop the ashes out
welding a row of sheetmetal plates like cooling ribs in between the top and bottom barrel in the same direction as the pipes might help disperse the heat from the bottom barrel along the the heat going through the top barrel
Its has good access from the front door to get the ashes out.
Use self tapper screws for the upper barrel
Most definitely
What is the average temperature in your shop with that stove burning? Just wondering how things are in your work area in the middle to opposite end of your shop from where the stove sits. Thank you.
Loved this! Great job!
Thanks!
I need to build a 2 barrel stove once my new shop is done. 2400 sqft just like yours.
It's been working awesome!
Good video. Next time put the top barrel vertical next to the burn barrel and the heat will rise through your tubes without a fan.
Thanks
Would this work if I change the bottom barrel to a ticker pipe and not a thin barrel
You can add a compressed air nozzle to the flame barrel if it don't produce like you want just turn on the air compression and turn it into a super stove!!
Haha I bet that would rip
It does, I saw it used at an auto body shop like the size of urs, sounds like a blow torch.
I imagine!!
How did the smoke draw out running the pipe like that was it smokey at all?
Are you gonna do an update on this stove how it’s held up over time whet else y’all have done to it
I would like to
You guys should have used a hole saw for the pipes
We did but it was no good and didn't want to go buy a new one
Hey, thanks for sharing!
Pretty crappy castings, huh? Forty years ago a US company sold a kit made entirely of heavy gauge stampings. The stove I built with that kit is still in service, original barrels and all.
@2:39 I see what you did there! HAHA
🤣🤣🤣
Did you make a follow up video?
Negative
@@JustinTBraun how did it do? Was it worth it? Still using it?
I have that same wood stove next to your barrel heater.
It's a good stove.
I am looking to build something like this, 2 questions i am putting this in my 2 car garage turned shop/man cave. Do i need a double burner set up and can i place it outside with a vent coming into the garage?
If the 2 car garage isn't to big you probably wouldn't need a double barrel setup
I wanna know hows it doing so far. I have tje same kit but just single barrel. I warped my front door from getting roo hot i think
We are going to do an update video soon. It will be on Cory's channel Low Range Garage
What are you going to do about the eves vent it is a big gap were the warm air will escape.
Also, looks like a pain to clean the ashes.
The entire roof is getting spray foam insulated
You got a horizontal flue, that ain't the best, you need it to slope upwards.
It's been changed with the new stove.
Amazing what lengths we will go to to waste heat rather than save it. Insulate the shop!
Its coming!
The door turned white because it has non-heat tolerant, carcinogenic Chinese paint.
Probably
When are you going to do a follow up?
I'm not sure. Maybe in the near future.
another lucky backyard mechanic your lucky you not get blown into little bits of flesh
🤔
Your stove heat output BTU is limited by the vent pipe size and the dryness of the wood you are burning.
yes
Big ceiling fan would help as well
We are going to add a couple
So how's it been working so far? I have a 40x60 barn also, and am wondering about a double barrel stove. Is it the best for heating like your title says?
It has been working fairly decent. I personally have a diesel furnace in my shop and would not go any other route. I absolutely love how efficient it is.
Great video! Have you thought about putting a duct from the fan down to the hole below the vent so when the fan is on it give even more heat?
Have not gave it to much thought
Need to get that dog a bed to lay on ...Good vid
Every time I do he wont lay on it lol
Very nice job on the stove 👍
Thanks
