Hi,
I suddenly started to have problems with my boiler. At the beginning boiler was slowly dropping pressure, so had to top up once a week.
Recently I have to re-pressurize the boiler every day.
When I get up in the morning bar proudly say 1-1.5bar. When tap is open or central heating is switched on, boiler after making hell of a noise (like it would want to take off) starts, but pressure drops to 0.2bar. After top-up pressure stay as per usual 1-1.5. If central heating is kept longer pressure rises to above 3 bar.
I am I right to assume that the expansion vessel is causing a fault. If so which one domestic hot water or central heating?
