Rinchen, The manifold as you've built it, looks very much like a bell. The entry is higher up, the exit is (almost?) at floor level. The heat will be trapped in this way, only to be solved by building the bench level with the barrel exit.

Yes the exit is 2 inch of the floor and a lot of heat is extracted in this transition area, but I still manage to stay above the condensation point in the flue.... just

Thanks for posting the photos. Is that 8" galvanised pipe you are using for the bench?

Yes it is. It is ventilation duct.

Hi everybody!
Well, i have a building question.
According to my calcs, my tube being six inch (15CM), that's 176 square cm, retracted from the 660cm² from my nearly 12 inch barrel (29cm diameter) i get 484cm² for the heat riser.
484x4/Π=616.24
Square root of 616.24=24.83.
I'm left with only 2cm each side.
And i'm woried with laminar flow etc!
Any opinion?
Thanks a lot.
Max.

Making more progress. A couple pics to show how I'm dealing with the transition area. In order to try to avoid the outlet being lower than the inlet, like peterburg talks about above in this thread, I've introduced a couple elbows to get things where I want them. Today I will finish putting the top on and firing it up again.

Nice job, I am sure that will put more heat into your bench, albeit with some more flow resistance due to the elbows. A higher chimney temperature should make up for that. Dont forget that if you don't have a (dry) bench build onto the ducting you will loose to much heat and you will end up with condensation even before it reaches your chimney.
