I have a combi boiler Saber 24 (I gather this is a Vokera) - the gauge reads 1bar - and is steady. But recently my hot water (from the tap) does not seem to have the same pressure (takes twice as long to fill the bath/sink). The boiler is around 3 years old. My central heating is fine and my cold water pressure is as good as it always been even when I change the temp of the water it seems not make a difference to the pressure.
Sorry if this not enough info - don't know much about these things.
