My house is heated by a combi which is installed in the downstairs

adjacent lobby to the outside (it's boxed in, about two metres long
altogether). A visiting builder has told me that when I come to
replace it (hopefully a good few years off) new rules mean I'll have
to get building control in from the local council who will tell me
where I'm allowed to put my new boiler, and it's current location will
not be an option. I think he's suggesting that it has to be installed
on an external wall.

Is this right? It will be a pain in the arse to put it anywhere else
and could involve some major dispution to the plumbing. If this is
true I'm thinking of relocating it now while I've got some work going
on to save disruption in the future.


With a flue that length, you must have a fan flued boiler. You will
have to replace it with a condensing boiler but unless the external flue
is in a position which contravenes current regs this should not be a
problem

Where does the flue exit? With a condensing boiler the plume of mist it
produces may be a nuisance and make the present location undesirable.

(If it discharges towards a public highway or neighbour's property less
than 1.2 metres(IIRC) away it shouldn't be there anyway.)
