You don't live in a real cold climate do you? You can't substitute heated seats for heat because the Windows will often fog up (depends on dew point and number of passengers how often / quickly this will happen).
I tend to leave recirculate On, A/C On and heat at 68F. It's comfortable and windows stay clear. It will use about 50 (give or take) wh/mi though (after things settle). I could run it lower but why be uncomfortable? I hate having a cold nose breathing cool air
There are days I could fiddle with heat to not run A/C but I don't want to have to mess with the heat every day. These settings generally work over a wide range and are comfortable and don't chew up to many watts. If left on Auto it will jump to 100 wh/mi.
No, I dont.. I live in the same climate the OP does though.
