My chimney stack has just been taken down below the roof line and covered over (capped) in the loft, when my roof was re tiled. We live in a detetched house with the chimney in question next to the outside wall.
Do I need to vent the chimney? If so I would have to put a vent low down in the fire place at ground floor level, but the thing I am unsure of is where to place another vent to allow air flow.
I dont really want to vent the air into my loft space as I am worried about the warmer air condensing. I cant put an air brick outside near the roof line as access is very difficult. Would there be any benefit of fitting a vent in the upstairs bedroom near the ceiling by drilling through the side of the chimney breast.
