      Electric heat is not always 99.9% efficient, resistive heating is.

      Heat pumps are more than 100% efficient(compared to resistive heating)

      It’s not bs, because we are moving heat, not creating it. You thinking it is bullshit will not change the laws of thermodynamics. Try to think about it this way.

      “Cold” is a made up human concept, it really is a lack of heat energy. The coldest is 0K, but even a Midwest winter is waaaaaay above that. Heat pumps (and all refrigerant-based systems) work by changing the phase of the refrigerant from liquid to gas to cool, or by compressing a gas to a liquid. This phase change takes energy from the surrounding air (think about computer duster, the can gets cold) and then pipes it inside, where it can be compressed to release the heat it just picked up from outside. In the summer you flip the reverse switch to cool your house.

      Here is an explanation from someone much more eloquent than myself:https://youtu.be/7J52mDjZzto?si=sYlNlpvGnJs16lwk

      So you’d rather trust your feelings? Just loon into it if you’re that skeptical.

      “at those temperatures”

      well, to a heat pump even -40° is still 230K, which is plenty of energy to move around and work with. It may be cold to you, but to a heat pump it’s not.
