vaillant combi boiler?

when we have the heating on the pressure gauge is the normal 1.2 to 1.5 but as we have had no heating on the gauge is on zero and when we run a bath the hot water is constant but the gauge stays on zero is this normal or should the pressure always be on 1.2 even if heating not on or water not running

the pressure guage should be reading 1.2 cold this will increase as it gets hotter due to expansion.
re-pressurize your system
