Hi,

I have a bosch worchester boiler 24i juniror installed installed about 8
months ago, recently it has started to act oddly with its pressure. Normally
sits at 1 bar but is bouncing between 1 bar right up to 2 bar but still in
the green of the guage and its losing water on the kitchen counter.

As its under warranty to I called them and amazingly they came out next day
change a part called the expansion veselle? connecting hose, and the valve
doodah it connects to.. the engineer came to the conclucion from the trail
of water that the diaphram in the veselle had burst causing this. So off he
proceeded to remove the boiler from the wall alone and changed it all inside
an hour! which I thought was good.

Today is day 2 of this work being done and so far no leaks, but I have
noticed the pressure guage flutuates slightly. Basically when not in action
it sits at 1 bar when in action this pressure raises to 1.2-1.3 I know very
little but I was wondering if this is acceptable an normal or a problem as
my old boiler say at 1.5 bar and didn't move at all. I only ask as while its
under warranty I want to make sure its all working efficiently.

On a side note for anyone else, its a good boiler despite this problem, only
niggle is the hot water is set at a non changeable setting, I think 55oc not
a problem for me but her in doors likes steamy hot baths. hat scald pfft.

Thanks

It would be unusual if the pressure did not increase when the
boiler is in heating mode!
