Before asking this, I confirm I have read the FAQ's, but haven't spotted the information I need.
My Worcester Bosch boiler recently had its annual service by British Gas. As it's in the loft I don't have the opportunity to see it often. However about two weeks after it was serviced I noticed it's running at higher pressure than normal, as low as 2 bar but often just under 3 bar. The filling key hasn't been left in by the way.
Am I right to think that it should be running at 1 bar ish?
What damage will be done running at the higher pressure?
Do I reduce pressure just by emptying water from a radiator?
The heating system doesn't seem to be heating radiators so good lately. Is this relevant?
