I put a rotorvent (dunno really what there name is in english ..) on the cheminy and now the Rocket works insanely good. I've been dancing about the house for 3 days with a big smile on my face.
Since the rotorvent I also have burned the Rocket several days in a row and it is really unbelievable it uses so little wood.
During the night I've covered the bench with a couple of woolen blankets and some sheep skins and I just about could touch the bench next morning/
I don't find theses all that amazing myself, but, what do i know
how did you make the thumbnail photo on this thread?

Max, I remember you used an electric fan in your exhaust path and it helped. Did you try a rotorvent/turbine vent first?
Yes i did, but, since it was against a wall, it didn't work well at all, hence the electric fan.
Steve Farmer wrote:is this a mythical perpetual motion machine that uses the exhaust flow to power itself into increasing the exhaust flow. I've never seen such a vent used or marketed so cant judge the device in question, but it reminds me of a scam product that is sold to motorists who are told they can enhance their engine intake airflow with it. Or is it powered by wind outside?
Not at all. It is supposed to act a bit like an H cowl. If it's not windy, it doesn't turn with the exhaust gases. When the wind makes it turn, also pushing the gases back in the chimney, the downwind fins create a depression, counteracting the overpresure which could cause smokeback.
At least, this is how i understand it. Theses are pretty common in France.
What is your chimney like? How tall, and how big inside? What materials? Is it mostly inside or outside the house?
And yes there very common in France.
My chimney is 15cm/5.9 inches.
Anyway in my case this rotor thing made my rocket work like a charm !!
And I wish it can be the solution for others too, the only reason of this post.
