That was the mock up stage. Burned it last night. I just spent a hr wire wheeling it. Shiny as a new penny now.

Running my propane flame thrower in it now, to dry up the core and burn off any smells. So far no stink @300f at the top of barrel.

Thanks for stopping by.

I've run it a few times to speed the drying up. The suction/draft is strong from the start. I assume it will keep getting better as it dries up.

We're getting the rain from the hurricane over the next few days. Here among the tumbleweeds So I'm using a propane flame thrower to dry it up a little faster.

The sound is like a blast furnace when I crank the fuel up.

Thanks for looking.

The mix I'm using is a sand, chipped rock and clay slip.

Then river rock as a fill/ heat sink in the mix.

Dan, my opinion, make a brick bell against that brick wall protection, you don't have nowhere near enough pipe for exctracting heat imho.

Sumthing like this.

Thanks for the link. (interesting) First thing I thought of was Pink Floyd. LoL

I for see a lot of feeding to keep the beast hot.

A batch box might be required.

On good thing about this. It might have taken a few weeks to build. I can reclaim all it's parts in under a day.

Well I tore it down to rebuild it correctly. Due to getting in a hurry, I skipped a crucial thing.

The insulation under the burn chamber. This heater is on a wood floor. A concrete board then brick pavers.(it was all ready here for a wood stove). Then the RMH on top of that.. Knowing the burn chamber temps could get the wood flooring hot. Don't think it would get to combustion temp but not going to take the chance.

This is what I did to hopefully remedy this potential problem.

I found 6 red mexican 3 hole block. I filled two of the holes in each block with perlite and clay mix. Leaving one hole open. This open hole will be out side of the burn chamber line. On the back end a channel was cut to allow air to flow around the insulated part of the block.

it took 8 hrs. by my self to take it down. The cob mix I'm using need a rock hammer to bust it up. Every thing was reused. I like this mud. If you screw up it can be fixed with out getting more supplies.

The 2nd build took 10 hrs. to build it back in the 2nd pic.

First one is what it looked like. The 2nd what it looks like now.

Third pick it of the first test burn. Even wet it has a great rocket sound.

Three year update. Still haven't put a finish coat on it.

Only have one small crack in the seat area.

Last season here in SE NM. only used 100 pallets.

This season with a record warm winter only used 40.(so far)

Haven't had to do any maintenance other that cleaning fly ash out of the pipe.
The steel 6"x6"x3/16"riser I think will last another season. Seen some flaking but nothing to worry about.

Barrel is well cured, black like a cast iron skillet.

Overall It was the best thing I have done to cut down on the wood consumption and still stay warm. Sometimes to warm LOL

What I find that is cool about it, is the smell of the wood burning out side. Not a smoke smell but a sweet like smell you get from smoked meat.

Dan,

Just wanted to say not to take it personally that few people are replying. The real measure is how many people are reading your post, which as I write this is 4375 views! Lots of us are interested in multiple ideas and read lots of articles, but don't think we have specific input.

For instance, I read your posts, but you are way more advanced than I am. Any question I would have at this point would probably come from an actual build just like yours. But I still learned from your post, and maybe some of your points saves me a week of rebuilding!

I want you to know you are adding value even if there are not reply posts in between your posts. Your posts are very good and the pictures mean we don't need to ask lots of questions...

Yes, Dan, thank you for posting such a comprehensive series of process photos and description, including the changes you made. Especially, thank you for giving an update after years of experience with the system. I wasn't around here when you started your build, though I remember seeing it shortly afterward.

Max had a good point when he suggested a bell for heat extraction vs. the short duct run, though as far south as you are, maximum effectiveness and flywheel effect is a bit less important than in the frozen north. Your setup obviously works well.
