Dodgy thermostat will also cause this, partially blocked heater core, heater control valves, low coolant - lots of things.
I don't think the amount of anti-freeze has anything to do with it, antifreeze (and the pressure cap) just increase the boiling point of the coolant, the coolant will still absorb all the heat possible from the engine, it will just reach boiling point well above 212dF or whatever.
Although is is a known fact that straight water will absorb and dissipate heat quicker than an anti-freeze mix.

You can also put in a davies/craig booster pump that'll shoot more hot coolant into your heater core. I got one (havn't put in in yet) because my AU does the same but thats only because i've got a davies/craig water pump in as well running the engine temp very very cool.

what about the vacumn controlled heater valve?? is that looking rusty/corroded..it might not be opening up all the way...its located in the inlet hose going to the heater core..and has a green vacumn line going to it...
My XF has a new one..and the heater works 100%..
although id also do what others said and check/replace the thermostat too..

can;t offer anything constructive apart from saying i don't think it's an EA problem - my heater (used for the first time ever last week) blows hotter than hell - much better than my parent's AU Forte/NF Fairlane...

Thermostat and heater tap in the engine bay will be contributing factors. Flush ur system out with a good radiator flush, with the heater on. After 15mins of idling...turn the car off, drop the hose or drain valve, whichever, and replace thermostat with 92C if your having problems with hot air.
Make sure the heater tap vacuum hose isnt perished so it opens the tap all the way.
