Yeah, the old one heated the battery through similar tech as heated seats. I think the only problem with the tesla heat pump is that it doesn't function well below 20-30F. I'm not sure if that's all heat pumps.

Well, the problem with the heat pumps in my house, is that near or below freezing temperatures, the outdoor unit has the tendency to freeze over, then either it has to run its resistive heater, or intermittently cut out and blow some cold air inside. It's rather uncomfortable.

I'm not sure you can get away with a design that has to sporadically turn itself off, and melt itself down in an EV.

		Something is wrong with your heat pump. Mine works fine during cold snaps. It doesn't blow cold air during the defrost cycle. Perhaps yours is undersized, or otherwise not designed for cold climates?

		Heat pumps on cars can go well below freezing without any issues.
