My wife feels the cold badly and the other night she cranked the dial all the way round to full hot. OMG! I thought my shoes were melting and my eyeballs felt like they were on fire. The driver's side vent conveniently points straight at your left hand on the wheel and I think my wedding ring liquified. Surely Land Rover have used some type of plastic developed by NASA to cope with the nuclear heat it produces.
Yes, three clicks from cold is sufficient warmth in my opinion.
