Hi
Just had a combi (worcester bosch) boiler fitted and all seems to work
great.

Pressure of main bathroom seems good and the shower of the bath (mixer
one) also seems fine.

My question is, in the en-suite, we have hansgrohe croma (3 litre
normal) and i was told by the british gas man who came around to quote
us originally on boiler replacement that we will have to change the
en-suite shower - can't remember why but i do remember him saying that
some types of shower does not work with combi boilers because the mains
pressure coming is now too strong and may start leaking??

The shower has an exposed bit from the wall, where i can control the
water flow on left hand side and temp control on right handside.

questions:

1) what are these shower types called that can't work with combi
boilers?
2) And is my Hansgrohe Croma one of those?

Some background info:

We used to have a shower pump - so our en-suite shower pressure was
pretty good.

After getting the combi, the pressure seems the same to me but then
that's just me saying without any specific test.

No immediate/obvious leaks that i can see from the en-suite shower so
far.

Looked on hansgrohe website and can't seem to find this info.

many thanks

If the pressure is similar - you used a booster pump, then it's not an
issue.
Would the BG person have liked to have been employed to fix the shower one
wonders.

He's on commission then for selling new showers.

The flow and pressure can both be adjusted per appliance with specific
devices. A non-ripping-off type of plumber would advise you of this.

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?

If it's excessive pressure that is a problem then a pressure reducing
device can be utilised for the shower feed. Not knowing the ins and
outs of the particular shower I'm unsure of exactly what the specs are
but it shouldn't be neccesary to change it.

There may be some truth in what he said if the shower was previously
connected to the low pressure feeds directly from the header tanks.
