the stove was placed in the middle of the classes of students...
then the pipe went horizontally, a little higher than the height of a man, towards the wall...
then, it passed through a fireplace located "in" the house (and not hidden in the walls), to provide a little heat on the upper floor when there was one...
I knew that, my father during a very cold winter (maybe 1956?) had installed a Godin in the middle of the living room with a vertical pipe outlet then a 90°C elbow then a long horizontal length slightly rising then a 2nd bend at 90°C and a pipe entering the final vertical chimney flue.
My memory: it heated the whole room enormously (better than a central heating radiator) because the pipe was very hot over its entire length....and it represented a hell of a heating surface.........but the smoke was still heading upwards (despite a false flat rising several meters throughout the crossing of the room).
It was the same at school with the stove at the back of the class...and the dunces right next to it
I think that at the time we weren't rolling on gold, so the slightest source of heat was good to take, which means that I don't believe in this very dangerous system for human life proposed by jaf (and animal too by the way) because
carbon monoxide CO = DEAD.As well as the reinjection of tars
and creosote in the combustion chamber of the stove, this will allow
to globally reduce carbon emissions since the
combustion will be more efficient
.
Well, it's funny, it reminds me of the very famous EGR valve which recycles unburned diesel fuel and causes the well-known problems now (see topics on this EGR valve in this forum).....I will not elaborate.
