I have a vokera combi boiler and it has low hot water presure, the hot water was at a fair presure when we moved in , can you help ?
there does not seem to be a pump on it and the cold water is very high presure.
Flow restrictor is the problem, take it out,try it with none in, if its warm enough youve cracked if not replace it there is 3 differant sizes or modifi it by drilling it out

there is a flow restrictor on the hw side that will be causing the problem, look in the manual to find where it is depending if its an he boiler or standard efficiency, hope this helps.
