DIY wood stove. Is A Double Barrel Stove The Best At Heating?

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.

[@JustinTBraun]

Not the greatest

[@tgvaillancourt]

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

[@garyweber6413]

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.

[@carlduggan4058]

Gary, how did you make your own aircete pipes? I’m looking to start a build like this now an considering best upgrades

[@MrThenry1988]

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.

[@JustinTBraun]

That's awesome to hear!

[@ZippoVarga]

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~

[@JustinTBraun]

That's a good idea. Hey thanks! Tons more to come! 🤘

[@NickMango]

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 👍

[@JustinTBraun]

Heck Yea!

[@AStanton1966]

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.

[@NickMango]

A Stanton1966 pavers? I’m very surprised that those worked better. That’s interesting.

[@AStanton1966]

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.

[@NickMango]

A Stanton1966 I gotcha 👍. Thanks

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!

[@JustinTBraun]

Heck yea!

[@benjamincrooker2533]

Great build. A fan power cut off heat sensor switch at the barrels along with a thermostat 30 ft away from the stove and it’s almost automatic. Just add fuel lumber and stuff. 😊

[@raincoast9010]

[@bradleymaddy7380]

Just an idea, use a barrel with a band/removable top for the top barrel so you have access to bolts etc

[@edwardesty4951]

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.

[@wilbertoaguilar7902]

Do u have a pic of your heater

[@marioarchuleta8723]

Diagram good sir !!!

[@myyesnetnet7285]

Link and pictures or diagram please to where we can actually see what you are recommending .

[@stevenmark8156]

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.

[@JustinTBraun]

That's awesome!

[@1966cambo]

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

[@JustinTBraun]

Most definitely

[@1fluffypie]

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.

[@vaporofdeath37]

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!!!

[@daverigby2577]

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

[@georgebudnick1992]

Use a temp switch to control your fan.

[@JustinTBraun]

That's the plan

[@jaystern2130]

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.

[@slipshaft]

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.

[@jaystern2130]

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.

[@GTNBY2]

Electric dryer temp switch works great for the blower. Kicks on / off at 120*

[@JustinTBraun]

Good to know!

[@kfstreich4787]

Thanks for the details, I can get some open top barrels, now I understand why, just need to replace my current dbl barrel stove.

[@JustinTBraun]

Anytime!

[@jwfinkler388]

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.

[@JustinTBraun]

The paint is coming eventually lol

[@brentfrederick6576]

The barrel feet that go between barrels are for wine and whiskey/ wooden barrels that's why they are tapered.

[@JustinTBraun]

Hmmm interesting 🤔

[@jwfinkler388]

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 KZbin 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.

[@Greenr0]

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.

[@tranquilowey1735]

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.

[@victoryfirst2878]

You guys should insulate the building. The heat will just go up and out your garage. Good luck heating the shop too.

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.

[@JustinTBraun]

We have been scooping it out with a shovel. Been working good

[@jasonbroom7147]

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.

[@wyattsmith8808]

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

[@guinness77100]

I saw another video where the author moved the flue 18" above the top barrel. He said it helped a lot.

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.

[@davekauffman8727]
