Vaillant Combi boiler, no hot water through taps when central heating is on?

Hi There,
We have a vaillant combi boiler which, for some reason, when we have our central heating on, no hot water comes through the taps, however when the central heating is off, the taps are fine and give hot water as they should, why can't i get hot water through my taps when the central heating is on?
