I have checked the flow valve by stripping it, found the impeller was sticking, gave it a good clean, re assembled, worked ok for a few weeks then back to no HW.
If there is something causing this problems, any suggestions.
Would not want to buy a new FV if there is something else causing problem. Central heating OK
By the way my friend is a registered gas fitter.
