extract so much heat energy that your exhaust gases will stall in that chimney. It is likely that you will need a little help to get your chimney to draft well
when and if we can cross that bridge when we come to it

Satamax Antone wrote:Well, rereading this, and looking at the pics, there is no way this stove can be retrofited with a rocket without cutting the top.
Way to small for any heat riser.

Glenn Herbert wrote:the first critical question is exactly how tall the space is from base of doors to top of back section of stove.
Glenn Herbert wrote:Subtracting thickness of new materials and top clearance above heat riser will tell what proportional dimensions could be achieved and how those compare to the equivalent diameter of the proposed system (about 6").
Glenn Herbert wrote:A question for an expert with calculations is how much heat can be generated by the size of j-tube feasible here. I would guess it would be less than the current firebox can generate at full throttle.

ronald bush wrote:maybe stack bricks on top of the stove for additional thermal mass. or even bricks stacked behind the stove against the wall.

ronald bush wrote:it seems that just setting that in your stove would only super heat the flue.
Glenn Herbert wrote:Having gone through this trial, do you anticipate trying to further tweak this stove, or building a standard type RMH with bell for next winter?
Glenn Herbert wrote:(How sturdy is the floor under the stove? Can you reinforce the supports if needed?)
Glenn Herbert wrote:I had the feeling space limitations were pretty strict, which is why I suggested a masonry bell instead of the long cob bench.
