I have just had a Vaillant EcoTech pro 24 combi boiler fitted his week, this was in place of my old gravity fed Baxi back boiler set up.
I have askd the engineer back as the hot pressure in all taps is less than half of the cold and when any cold tap is used it kills the pressure in the hot.
Any help would be appreciated so I am not fed too much technical BS on his return
