thanks for all the info.


to answer somes questions:

a) yes we did have a booster pump - but i was told that these pump will
not be as strong pressure as the mains?

I was told mains pressure - 7~8 bars by local corgi registered boiler
guy and boosters won't be as strong as that?

b) don't think the British Gas guy was quoting us for putting a new
shower - he just said we will need to change the shower in en-suite if
we get combi so not sure if he was getting anything out of it.

So Lurch, are you saying we can stay with the shower we have? your
reply stated what my shower can do - 1 control for flow and 1 control
of temp. so that means it will work with combi?
