Just had a visit from a plumber to quote for new boiler. He ruled out
the location where I was planning to put it, under a single story
pitched roof with vent through the roof. He said that the latest
regulations say it's got to be 2 metres from a boundary (boiler would
be on party wall so no chance with Worcester 35 Cdi as planned) and
that the window above the roof is too close. 2002 building regs say a
fanned flue doesn't have to be more than 300mm from a boundary or a
window, even 600mm should be achievable so I'm a bit perplexed where
he's got these distances from. Anyone have any ideas? The only real
alternative location is in the loft and I'm a bit concerned about the
noise and long DHW pipe run.


AIUI the 2 metre rule is applied with horizontal discharge flues which
"blow" towards the boundary. The use of high efficiency boilers often gives
rise to pluming (visible water vapour sometimes described as steam) which
can and does upset neighbours. Litigation often results from sensetive
neighbours in these cases which is not one of the plus factors for
condensing boilers of course!
I can't see a vertical discharge flue from a CDi giving rise to complaints
and unless it is really likely to giver rise to products of combustion
entering a window it would be worth further investigation.
