Heat pumps generally come with an electrical resistive backup in case it's too cold outside, so even at arbitrarily low temperatures a heat pump can only drop to 100%

    At that point, the heat pump is off and you're using a resistive heater. You can't just glue an LED to an incandescent lightbulb and call it a 50% efficient incandescent lightbulb.

    True. You know, the moment I left that comment, I thought that was pedantic, I shouldn't have said it, but by that point if I had deleted it it would just sit there saying deleted forever and that would bother me even more
