So what you do then, is choose a charge pressure, eg 1 bar (as you stated earlier and I disagreed with)! then work out the static pressure (system pressure) and round up, ie 1.2M to 1.5 - then choose that constant figure next to that, ie 0.152 then times it by the system volume and then choose the next sized expansion vessel up?!!!
no as i stated earlier you work out the system volume first
you pre charge the system to 1.2 whigh allows for the head
not the bleeding expansion vessel

kev-a final question please mate: for a domestic house (3 beds semi) - will a 12 L vessel charged to 1 bar be sufficient and operate correctly, even if it is slightly oversized and over-pressurised, from your experience??

The answer to that question depends on the system volume, and the initial system pressure.
Most manufacturers give you the pre-charge pressure, you can work it out from there.
The only thing to remember is the pre-charge pressure must not be less than Hydrostatic head.
