Vocaro Combi Boiler - hot water pressure drop

I have a combi boiler - the gauge reads 1bar - and is steady. But recently my hot water does not seem to have the same presure. The boiler is around 3 years old. My central heating is fine and my cold water pressure is as good as it always been. Sorry if this not anough info - don't know much about these things - I work in IT and not as skilled as a plummer/heating engineer.

All help welcome

i suspect you mean the flow out of the taps is less.

i also suspect the boiler is a vokera compact. confirm the boiler model and we should be able to tell you what is wrong.

Yes - hot water tap pressure is down - I had a look at it - it is not a vokera (my father told me that was the type) - it is a sabre 24 - the water is still hot - but when I change the temp of the water it seems not make a difference to the pressure.

Thanks

Dave
