My little 1.2 Corsa (my commuter) has an absolutely awesome heater. Can only manage minutes on 'full' heat,

Been doing some research and it seems most vehicles with the Ford Xflow engine in seem to suffer from poor heating. Even with all the upgrades I've done, I would only describe the heat output as 'luke warm'.
