I am sure lots of you have experience of these but I have a few
questions.

You get what you pay for to an extent. So go with decent brands and at
the higher end of the power specs on the boiler and it will do what you
want.

At present I have a 20 year old Wickes boiler 45k btu(works fine apart
from replacing the pilot stat every few years) on a Y plan system,
this is hung on the wall in the kitchen, would a combi be a fairly
straight forward replacement.

The procedure needs a little planning, but is not that difficult. When I
did mine it went something like:

http://www.internode.co.uk/loft/boiler.htm

The present shower over the bath is a pumped system, can the pump be
dispensed with when using a combi (understand combi's use mains
pressure, mine is ok but with hard water)

Yup, you can't generally pump mains water, and the hot will be at mains
pressure.

The loft tank only feeds the hot water cylinder and the power shower,
all cold taps, appliances and WC's are mains fed

Which makes life simpler. If you are replacing the shower anyway you
don't even need to worry about the shower feed particularly.

Combi(condensing) boilers used to have a bad reputation for failing,
has this improved on recent models?

See Ed'd boiler choice FAQ,

Have you got a link for this?

he spells out many of the details that tend
to influence the reliability etc. Also remember to compare like with
like - you can't buy a basic cast iron lump with minimal electronics any
more so there is no point comparing a combi with that.

A modern condensing boiler designed to be one from the outset (rather
than a old design that has been reworked to be a condenser later) will
tend to be better.

Any recommendations

Reasonable starting point with links to the other FAQs etc:

Thanks John for your input, as the new boiler will have to last for the
next 20 years+? I will do a proper job and not go with the cheapest
available.
Useful information

I have not posted much in this thread as the usual flame war has arisen.
link to FAQs below.

The boiler one is 20 years out of date.

So (only) you say. Unless you can provide better, it hardly matters.

You can't pump mains water, unless you have special permission.
