Why’s that? What does a heat pump Model 3 do that a “crappy old” Model 3 doesn’t?
I’m reserving judgement until February when the real cold weather hits. I suspect that the heat pump won’t be all that at -5F. Whereas a PTC heater still will do a good job warming the cabin ...
So yeah - I totally agree, the psychosis around every little running change “OMG NEW VALVE STEMS!!!11!! WATCH MY 20 MINUTE VIDEO” is nuts.
At it's worst, a heat pump will be the same efficiency as a resistive heater. At more optimal conditions (>14F) it is much more efficient.
