Tony just an observation but how is it possible for that flue to be so close to the external of the corner if the walls are 900mm thick, that returning corner wall will be 900mm also, so on the inside the internal corner where the boiler is would be 900mm back in from the external corner, that flue centre looks to be about 200mm. There must be bends hidden in the wall.
What's that sticking out on the floor above about 600mm back from the corner. Looks like a flue on the angle.
Pity too see the way theyve knocked those holes out for the soil and waste pipes, shame on a nice sandstone old building like that.
Hi Davey, that's an old telephone cable bracket mate, regarding the wall no the brick wall is only 9" engineering brick and the gable end of the tenement (where the boiler is hanging on) will normally about 18" but the boiler is in a cupboard and the wall behind must only be about 6" at that point , there's no other bends apart from the flue bend on top of the boiler and a 45 degree bend fitted to that boiler bend to take the flue back to the wall, the boiler is on the gable wall inside a cupboard which used to be where the gas cooker would have been installed, the boiler is now in a bedroom but that would have been the original kitchen with a bed recess and the lounge had a bed recess too but now there's an internal kitchen and a shower room where the two recesses were.
Normally the back wall of a tenement is about 27" but because the boiler is in that cubboard then it's now 36", inside the bedroom at the window there's a return wall of about 12" then the cupboard so that's why the flue is so long.
Btw it's a pig of a job to core that length of hole,you have to keep withdrawing the core bit and removing the extensions each time to get out the cored sandstone from the core bit.
Hence the reason I'm not too keen to make another hole.
