Biography
13 acres in extreme rural Montana 100% off grid since 1983. Solar and micro hydro. Summer time piggy farmer. Restoring 2000-04 Subaru outbacks wagons for fun and a little profit. Not quite old enough to retire YET but closing on it fast... until then I must occasionally leave Paradise "home" and run large construction cranes on union job sites across the inland northwest. I make (Well try) A-2 A-2 cheese, I love cooking with my wood smoker for everything! Would not live anywhere else but rural Montana ! My wife Liz runs "Rocks by liz" a successful Etsy store and we have a summer booth at the Missoula peoples market. We currently breed and raise persian cats but are about to retire all the girls and let them be happy kittys for the remainder of their days.Oh and my biggest thing is... I LOVE MY RMH !

I agree,  treats should help calm the savage beast.  
After all, freshly-baked cookies will change my attitude any day, should work with a lonely donkey.
Hi Matt
All four walls, floor to ceiling, and the ceiling itself are measured.
The core and core door are not measured.

Hi Matt;
The exhaust box is not counted.
It is very small, located at floor level with an opening of apx 8" x 12".
The walls and roof all count inside the box, unless insulated.
The height of the core will change, where the highest heat is concentrated.
It does not affect the output of the Batchbox.
Peter calculated the correct ISA for each Batchbox size's output.

We have two.
A poor man one, for Liz in her art studio, this gets daily heavy use.
And my 1940's WW2 surplus vice, it gets used quite often itself.

Hi Matt;
I like your design with the step out for the exhaust; both my Shorty core build and the Studio Dragon build use one to bring the exhaust stack into proper position.
Your core heat will rise before sinking; you should not have any issues.
A straight stack is always preferable. Be sure to position the pipes so that all moisture stays inside, and I suggest using metal duct tape at each pipe connection.
Shorty core is easy to build, except for the three slabs needing to be poured.
I believe Peter, reduced by ISA 10% from the first-generation Batchbox design.
It does require a bypass pipe to ease cold starts, but with a stepout for the chimney, installing a bypass is pretty easy.

Build a small brick box "manifold" and add a cleanout door, either a stove pipe cap or a cast iron door.

And a big yes on adding the plumber's tape to support it.

Yes, that is the correct primer and glue.  Make sure there is enough, and the glue has not solidified.
A hacksaw will work; a side grinder with a skinny wheel would be faster.
Wear gloves, and if you have one, use a face shield.
If your original pipe has no play, you may find it hard to make all the connections.
When priming and gluing PVC pipe, you need square cuts and complete insertion of each piece to get a water-tite bond.
If you have trouble, they do sell a slip-on repair piece called a compression fitting, no glue needed.

Hi Marta;
Yes, this post is intended as satire.
It is all true that I have twice bought #10 of blank newsprint.
I like it a lot, and now use it exclusively, rather than dealing with printed paper.
The real point here was how little wood you burn with a mass heater.
Paper is cheaper than cords of wood... and USPS drops it off at my door.

Oh my, I have piles of dry bark duff in the wood sheds.
Very little, paper birch nearby, as that is an excellent fire starter, and I would use it. I love the smell!
Pine cones work, but not really well until dry.
I like using newspaper, fast and easy, and it works every time.
Oh, and do I use a propane torch on the paper and kindling in the shop and studio, but just to get them going faster.

I intended this post as a satire.
My point here was not really the cost of the newspaper, as much as how little your RMH is burning.
$50 for paper versus the cost of multiple cords of wood.

It is a win-win when you start heating with bricks instead of wood!
