filling a bath takes forever, cold water flow is at approx.20L/min. With temp setting at mid range flow rate at hot water tap is approx 5-6L/min. I realise that combi's have to heat the water, but this seems really low. It has always been like this . Thanks in advance.
after checking the above, try removing the cold feed pipe to the heat exchanger, there you should find another restrictor with an o-ring, remove the o-ring (somtimes swell). this might improve the flow.

First check that the cold water inlet valve is fully open, if so then check if there is an inline filter may be blocked
