Heat pump can also use main gas (cheaper than electricity) when the heat pump would be ineffective/unavailable.It will just not use the resistive coils much to save power. A home heat pump is the same.
It's not necessary to have a dedicated PTC heater anymore. Tesla uses one or both drive units stators to generate heat by "stalling" them. Combined they can output 7+kW of power. Here's a good video that explains it:All should have resistive coil heat since the Heat Pump is slower and less effective in extreme cold. It will just not use the resistive coils much to save power. A home heat pump is the same.
Which heats up faster and hotter?
I have nothing valuable to contribute here other than to say I wish I had the heat pump. Over the last two months I’ve been consistently driving in temps averaging between 20s and 30s and my efficiency is approx. 370 Wh/Mile. In fact, TeslaFi only knows me to drive in temps like this, and it thinks my battery capacity is significantly lower than rated on my seven month old 3.
My assumption is that would be improved greatly with the pump, tho I understand other threads dive more deeply into the comparison.
To the original question, it heats up real fast, zero issues there. I thought I’d miss the heated steering wheel when I moved from the S, but with pre conditioning I am very comfortable. The biggest heat issue for me is when temps get down into single digits while driving, the car doesn’t seem to be insulated very well, have to really keep that heat cranking if I’m wearing a t shirt.
You are wearing a t-shirt in the car in the middle of the cold winter weather and have to "really keep that heat cranking" to say comfortable? I think that I have found the explanation for your "370 Wh/Mile" energy usage.

isn't a heat pump just the AC compressor in reverse? More wear and tear on one component vs two?
