the boiler is set at 1.5 bar and when the heating is turned on, for the first hour or so the boiler goes to above 3 bar and drips out the pipe outside(between say 50ml - 100ml).it then settles down to normal.
in the morning the pressure is down to 1 bar (the heating has been off).
when i then use hot water, without the heating being on,the pressure goes back up to 1.3 bar.this has happened for a few days now.i thought it was the expansion vessel, now i'm not so sure.
