I have a peculiar problem with my Potterton Combi Boiler (Potterton 28). The system looses preassure, when cold the gauge shows 0 Bar !! .. but when running it is about 2 - 2.5 Bar !!
The Boiler does not seem to cut off even at 0 Bar when it's cold !!
It did have a minor leak about 2 months ago which was fixed and there are no more leaks now.
The tempreature gauge (on the boiler) show that the water temp of 80 - 80+, I am not sure what is happenning. I called a local engineer he suggested a leak and injected Leak Sealer into the system but it still has the same problem.
