In summer, I do plan to do a mod to disable this (put it on a switch) to increase fuel economy. The electric heater kicks in under set conditions, but one of them is until the coolant temp is up to 167F! By then you should have very hot heat coming out of the vents.
Have you looked to see how it's programmed? My car only allows it under certain conditions:
temp below 50/ coolant under xxx/Eco mode/ max heat/ low vent. How they're programmed they seem to really only work when there just isn't any heat coming from the heater.

Also fantastic mileage for -1F. Thats some thick air for that mileage.
