What options are there to put a 100mm pipe horizontally through a slate
The slates are in poor condition. The roof will eventually be replaced. I
don't want to put up scaffolding, but can probably reach round from an
adjacent Velux window. There shouldn't be any flue positioning issues, the
flue would actually continue for some distance before the terminal, away
from the window.
The alternative (which I would prefer) is to shove the flue up the existing
chimney and out of the chimney pot (decommisioning the affected fireplace).
How easy do you think it would be to safely create a sufficiently large hole
in the side of the chimney to manipulate this lot into place? From the party
wall, there is about a length of the brick to play with in depth, excluding
the face of the chimney. The flue would need to enter from the side.
According to our house survey, the chimney is unusual in having the flues
completely one side or other of the party wall, rather than spread out and
shared between the houses.
