Hi all, hope someone can help.
I am having trouble with my combi boiler. First it was low pressure in a morning so would have to top up and press reset. During the day the pressure would then go past 4 bar and down to the bottom of the gauge. A plumber told me it was low pressure in the pressure vessel. I have added air and now the pressure seems fine. The problem now is I have water that flows hot then warm then hot then warm. The heating is only warming the tops of the radiators then turning off. Again our local plumber said it was the PCB. This has been changed with no effect. Any ideas anyone???????
