I have a Baxi 105e instant, noticed when the heating was on the pressure reached 3.0 Bar, then the relief valve opened and it dropped to 2.5Bar, it was suggested I repressurise the expansion vessel.
So I set it to 1Bar and the operating pressure remained rock solid, and I observed it over the next seven days, although the operating pressure remained steady each day it had increased until by the end of the week it had reached 3Bar,over the same period the cold pressure decreased and I had to top up with water.
I suspect the expansion vessel may need replacing, any idea how much this would cost or can anyone suggest another resolution.
