Hot water and central heating Fine!
But Presure increases over period of time.(Not staying at 1 bar and going to 2bar it now goes from 0.5 bar to 2 bar when heating is on and gradualy rises over a week or so until it vents)
Noticed vibration noise when hot water is run at the boiler.
When hot water run for say shower or bath I have noticed central heating pipes get warm (not Hot).
Fitted new external expansion tank not made any real differance.
