You are not adding anything to the conversation, but I still love pedantic comments like these.

  Hmm, as somebody who knew a bit about heat pumps but not much, I did find it added to clarify/distinguish between the main mode of operation of heat pump, used to accomplish the actual heat transfer; and what power / mechanism is used to move the mechanical bits. I.e. an internal combustion engine implicitly uses some kind of burning fuel; if on the other hand you want to use electricity as energy source, it needs a different kind of engine entirely. But that, as I understand from the post, is not the case here - heat pump as described here can operate on same principle and look broadly similar in its core parts, whether powered by electricity or something else.
