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.
