Low hot water pressure

[CDI]

Hi,
I have a 3 year old Bosch Wocester 28CDI,
The CH works fine but today i have found the hot water flow rate from the taps is greatly reduced, the water is certainly hot but not much of it.
Any help would be greatly appreciated
Tnx
Ian

Could be your diverter valve needs attention. Best to get a Corgi to check it for you.

could also be the dhw heat ex is full of limescale

could be you want free advice, and then use sarcasm when it`s not quick enough . could be you mistook me for someone who cares about your boiler

has your cold water flow rate dropped if its the same as previous then to have a suden drop in flow rate on dhw could be the inlet filter blocked or the flow restrictor blocked the first is a pig to do the second about30mins by the book. can you measure your max cld flow rate at the taps then the hot.the hot should be 10lt per min .no point in pulling the boiler to bits if the present flow rate is corect

Could be i'm glad you are not my local plumber
Also not knowing me why should you care?


Thank you to everyone else for the suggestions, turns out we had a major pipe burst so the overall water pressure was down for a while
All ok now
