I have a Vaillant turbomax boiler and have recently changed a radiator. The problem i have now is that the pressure in the boiler is continually rising from 1bar to 3bar +. If i drain water so that the pressure is back to 1bar, the same happens agin. Any suggestions would be appreciated.
I would suspect that you have not closed you fill loop correctly.
If this is the type with the L shape key at the front underneath the boiler, try closing it as far as you can then take it back very slightly, sometimes they do not stop in the correct position.
