Mike Haasl wrote: Looking at the Batchrocket.eu designs, if you wanted an open system without a door, couldn't the bricks just stick out like on Peter's older shop heater? Then you can skip the welded box on the front all together?
Mike Haasl wrote:First off, from your pics above, I didn't realize the steel box went into the barrel, I thought it just stuck out :) Does it continue all the way across the barrel to provide some connection at the far end of the barrel? If so, I'm wondering if there's enough CSA on either side of the U tray to let cooling gasses get past the firebox and down to the exit?
Mike Haasl wrote:If I used split firebricks, does it need insulation around the firebox?
Mike Haasl wrote:It sounds like that design doesn't have a P channel or any sort of secondary air tube. It even sounds like the front is only partially covered. That would make it a lot easier to build...
Mike Haasl wrote:Peter, how did you fit the barrel around the fire brick assembly? It looks like if it has to extend out into that metal box, you'd have to put the brickwork together inside the box and barrel.

Mike Haasl wrote:I had a dream last night about a small batch box that fit inside a stack of two 55 gallon drums. The total footprint of the heater was the drum diameter. It didn't have hardly any mass so the heat all went right into the room. This gave a quick, fast heat but it lasted as long as the wood was still in the firebox. Perfect for a shop or garage that only needs heat for a half a day every once in a while.

david higos wrote:I would like to be sure I understand what Peter means when he says to Aurelio "the core should be lifted at least up to the level of the bench' ceiling". By the core is he referring to the base of the combustion chamber? Is this a general feature or specifically for that design? Does it help to lift it higher?

My (limited) understanding was that a heated seat gives so much more efficient heating than radiating the heat into the room. Will a single bell keep the house warm 24 hours on only one firing?

No thermal mass, no heat storage? Or does it do that another way?

Tuve Lundberg wrote:My house is small, and the space for the burner part is limited, how compact can they be, and how close to a plywood wall?
Tuve Lundberg wrote:I was thinking the thermal mass could replace my current sofa, but due to the geometry of the room and placement of the current chimeny, maybe I should make a corner sofa out of the mass. But then the pipe length would be something like 11 metres. I have no idea if that is too long.

Tuve Lundberg wrote:I read about batch boxes today, and I can see how one anxious teenager in the house is really going to be relieved at having a closeable door. The open hole would freak them out.
