Heat pumps can provide an “efficiency” of some 300-400%+. The “trick” is that they use electricity to move heat instead of creating heat, which is why heat pumps stop working well under a certain temperature.

They kinda work like a reverse refrigerator. A fridge takes heat out from the inside and moves it to the outside. A heat pump does the opposite.

You’ve completely failed to answer their actual question, it was the claim of less than 100% efficient heating they were asking about…
No. He was replying to this post:

The intricacies of why a crypto minor is less than 100% efficient when working as a heater are easily deduced, unless you’re precisely the sort of midwit that likes to leave replies such as the one you left.

Heat pumps which use energy to move heat around are more efficient than using energy to generate heat directly.
