Thread: Alloy stove chimney ?

Ah, right you are - it's fat enough in proportion to the fire

Yes 125/150 for domestic sounds right
The outdoor fire thing is just that I helped a mate build his and he had to upgrade from a smaller one to one around 250/300 diam because the smoke was all spilling out the front, but his open face on the fire is pretty tall too.
Those tent stove things look bloody good
