Change the thermostat, its only a couple of quid and it got my admittidaly pathetic 90 heater blowing 'warm' air out ( it is the easist componant on a landrover to change, ever), It transformed mine from NO warm air to at least something for under a fiver.
Oddly doing an engine oil and injector flush make the thing get up to temp 3 times as faster, no idea why but I am hoping its just becasue lots of gunk has been cleaned out.
Consider a fertiliser sack on the front rad aka farmer style in freezing weather, this should give a bit of a boost once the thermostat kicks in and starts circulating water around the radiator.
