I've recently replaced the expansion vessel on a Worcester 24si combi.
I've charged the vessel at 0.5bar as per manual while the boiler had been drained. Then I filled the boiler up to 1.3bar.
Would the pressure on the expansion vessel be the same with the pressure of the boiler when the boiler is cold...i.e when it has not worked for a few days or would the pressure on the EV stay on 0.5bar even after filling the boiler?
