Rocket stove for large, leaky shop  RSS feed

I have a25 X 30 shop.  It has poorly insulated doors and leaks air.  It had a double barrel stove that was dangerous. I put in a air tight stove that is too small.  I want to replace that with a rocket stove but doubt 1 barrel will provide enough heat.  I need fast heat occasionally, so a rocket stove is the best design.
This has probably been done to death, but I haven't seen an answer.  I think a regular rocket design will work, but wonder if I can add a second barrel to the side of the first barrel with the flue going straight out of the second barrel's top so it doesn't cause a reduction/turbulence in the exhaust.
I think this design would work, but want confirmation or a better alternative before trying it out.
Thanks!

Maybe something along these lines?

This one worked for me in a shop at least as large as yours, complete with leaky doors. That is, when you mean 25 x 30 in feet, when it's meters have a close look at the one above.

In case one of these possibilities seems appealing to you, please plough through the batchrocket theory and so on.

Hi Michael : Welcome to Permies!
My shop is 24 x 32 with tall ceilings and badly leaky doors. Heated it with a double barrel stove for 20 plus years, here in northern Montana . I could have that stove roaring (the wood gobbler)and over by the doors your wrench would stick to your hand. Shop cooled off 30 minutes after the stove died out.
Took that stove out this summer and it is being replaced by my new brick bell rmh shop heater.  (permies.com/t/94980/Brick-Bell-Shop-Heater) It's still under construction ... wish I had started building in May!

It's not a batch box but an 8" J tube.  There is a small possibility that I might change it out a batch box in a year or two, if I am unhappy with its overall performance.

Most brick bell rmh's do not use a barrel . I designed one in because, like you I want instant quick heat I also want that heat stored for more than 30 minutes.

Lots of possibility's with a Rocket, you just need to decide which one is right for you.

Do you have a copy of the Builders Guide ?  I highly recommend one!
