Because I am cynical and don't believe everything I am told;)
No, if this is true then I am wandering how the current high output
broken boiler ever got installed in there in the first place(it's not
that old). When I bought the flat (two years ago) shouldn't the survey
have indicated that this is a problem? The full run from the gas
supply to the boiler is around 25 feet. It runs under my nice
laminated glued down living room floor, thru to the kithcen to service
the gas hob and then carries on to the boiler at the back of the
house. I don't want to have to dig up my floor unless really
necessary. But it looks like I will have to.
Thanks for all the replies,

Yep, Agree. The better surveys usually cover themselves with "if you are
uncertain of the condition of the gas/heating/plumbing installation" you
should obtain a report from a specialist.
Then it would depend on how thorough a specialist you got in.

Right, I've currently got a combi boiler with 93,00 ish BTUs. I have 5
rads, three small, one medium and one large (sorry I am not up on any
special technical names for raditor sizes;)
I'm replacing the boiler, question is, is the current output adequate?
Do I need more? Can it cope with less?
All help appreciated in advance.
No, yes. Even if your radiators are all running on maximum, you're
probably not going to exceed say 25,000 BTU. However, you are a
much more demanding user than your radiators because you want hot
water now, not in a minute's time. So the question you should be
asking is if you're happy with your domestic hot water output - i.e.
is shower etcetera acceptable.
Combi boilers are sized for the hot water usage. Unless you live in a
converted 20 room hotel with holes where the windows should be, any combi
boiler will have enough power for the heating. Your main concern with
heating is how low the boiler can modulate down to, to avoid short cycling.
This can be a concern with the 35+kW boilers, which often don't modulate as
low as 24/28kW models.
