Ever since we moved into our house a couple of years ago, our heating
has been a little noiser than i would have expected. There is a
banging or rattling when the pump is on as it moves the water around
the house. Its only in one place. Also, the actual pilot light is
starting to play around, as is the overall maintenance of the beast.
[Its a Baxi Bermuda, around 20years old]

so the question here is, i want to get this replaced with something a
little more modern and efficient. I don't want anything too fancy for
the front unit, more interested in the back boiler.

What prices am i expecting to be paying for a CORGI engineer to come
and replace it? Whats the procedure? Do i purchase the fire system
and then ask them to replace it? I have asked British Gas
(home.co.uk) to come around and give me a quote, again, what price
should i be expecting?

Any advice here would be helpful. thanks

Baxi Bermudas were great in their day - I've owned two of the things - but
they're very inefficient by modern standards. I would be very surprised if
you could get a back-boiler replacement. When my second Bermuda died, I
replaced it with a wall-hung boiler located elsewhere, and installed a more
elaborate coal-effect gas fire in the fireplace.

You may need to consider doing something similar. Some boilers can even be
installed in attics if there isn't another convenient location. If you go
for a sealed system, you will free up the attic space currently occupied by
the F&E tank. Maybe your new boiler could go there?

Aaah interesting SetSquare, you know i never even considered that. So
basically a boiler in the garage of the 'white-box-hung-on-wall' would
be acceptable. I have to admit the 1970's look of the fire place was
definitely getting on all our nerves and to see it go won't be causing
any tears whatsoever.

Our gas mains supply actually comes into the garage and then through
to the house, so this may not be as a big a job as one would have maybe
have thought.

With that in mind, what sort of price are we talking about here? ball
park figure?

The garage will be fine, provided the boiler's on an outside wall for the
flue.

Don't really know about cost - mine was done 12 years ago. At the time, it
cost me about 1200 quid (excluding the gas fire). I guess that you'd have to
multiply that by a factor of several!

With a modern efficient - probably condensing - boiler, you'll save a
dramatic amount of gas. You'll need to overhaul the control strategy at the
same time - making sure that there is a boiler interlock to turn the boiler
off when CH and HW demands are both satisfied. This will require zone
valves, room and tank thermostats - and probably TRVs on all but one
radiator. The new setup will also be fully pumped - whereas you've probably
got a gravity (convection) hot water circuit at the moment, with little
control over the DHW temperature.

If the old system is around 30 years old, you'd be better off replacing the
complete system, rather than try and modify the old.
For a complete system with a decent make condencing boiler, you'd probably
be looking at under £3500 but not from British Gas, get quotes from local
independant plumbers as well.

A reasonable guess might be about 4 man days of work + the cost of
boiler and materials (say at least 1200 for those)

Cost recently for combi Baxi 105e boiler in a three bed house with 7 rads
was £3500. That was in Essex. Dont know about ur circumstances as you havent
mentioned how many rads or how many beds you have but theres a figure for
you to compare against. I wouldnt bother with BG one of the quotes with them
was pushing 6k for exactly the same specs as our local fitter
