I'm mildly curious why they use direct electrical resistance.
It's not like you can't make heat pumps that operate down past 0F. My mitsubishi mini-split:
1. Can produce it's full BTU load all the way down to 5F, and 75% BTU load down to -13F.
2. Doesn't bother to blow air until it's warm
:) They aren't even that much larger than a resistance based coil system (though I could imagine the model S may not be able to fit them) |
