If your house leaks a lot your house can become a better chimney than your chimney.
Tell me more. Was that comment in response to my 'no smoke' at the top of the chimney....I was just
thinking my fire was very hot and efficient, so I didn't see any smoke but you could see rarifraction of
the air surrounding the chimney cap. During the burn, once established well, I opened the door quickly
and fully to see if any smoke would come into the room and it did not.
Continuing with your thought process of house being better chimney than the chimney; that's why I made
the comment that my chimney cap is higher than the conditioned air envelope of the house....me thinking
that had something to do with when a house becomes a better chimney than the chimney.
Also, for the last 3 weeks I've been working in the Cape Cod style knee walls, on the sloped ceiling, and on the
collared/flat ceiling making sure we are as sealed as we can be.....me thinking (maybe wrong again, I'm still learning)
that any leak prevented in the attic/upper most ceiling/wall penetrations minimizes the stack effect and the pulling
of air down thru the chimney and into the house.
Do I have this all wrong?
Yesterday with that first burn I was really happy because-
1. the good draft/quick start/little time needed to establish the fire with the door closed.
2. no backdrafting/puffing of smoke into the house when I quickly opened the door
But I know I'm not there yet......something I'm not thinking of yet?
