hot water temp?

when the combi boiler is heating the hot water for the shower or hot water tap the temp varies between warm and hot and as only started to do this after a plumber drained the system to fit a new water pressure switch.

check that the flow rate is not too high, around 9 - 10 litres per min for most boilers.
