Over a week would you expect to see any pressure drop on a Worcester Bosch 28 CDi? I have seen a very small drop over about a week after re-pressurizing the expansion tank and cleaning and re seating the PRV
The gauge read 1.5 bar when I refilled the system. It goes up to 1.9 to 2.0 bar when CH on. When CH off it now drops to about 1.2 bar. So nothing major but is this normal? Or is something wrong.
