Thankyou for all your help. i've managed to raise the pressure as suggested
using the filling loop and it's now just below 1.5. We'll keep an eye on it
to check it stays there.

Hi, I wonder if anyone can help. We had a new boiler fitted a couple of
months ago (an ariston combi boiler). ON the front of the boiler there is
a
pressure gauge and we have noticed that the pressure is down lower than
the
manual says it should be. The manual says between 1 and 1.5 bars and ours
is
showing about 0.5. This stays the same when hot water is used but rises
when
the central heating is turned on to about 1.5. However, despite this it's
working perfectly ok and gives us hot water and heats the radiators.
The plumber who fitted it seemed to do a good job when he did the boiler
so
we had him fit a new bathroom after and we werent happy with his work. He
promised to come back and sort out the bits we werent happy with (we
hadnt
paid him the full amount) but he has never turned up to do this. As we
hadn't paid him everything we were quite happy to leave it like this as
we
can finish off the other bits ourselves, but because of this its put us
in
an awkward position with the boiler.\We don't want to have to ring him
unless we really have to so if anyone here can give us any pointers we'd
be
really grateful!
Is this lack of pressure anything to worry about and is there anything
simple we can do to rectify it? We've bled all the radiators and the
actual
water pressure through the taps is very high if thats any help.

Please read the Sealed CH FAQ.
If you have more than about 10 radiators then it's possible that you
should have had an extra expansion vessel fitted.
