John Larkin is a gullible sucker for all the propaganda spread by the fossil carbon extrraction industry.

The point about a heat pump is that it delivers more heat energy than the electrical energy it consumes when operating across a small temperature difference. As the input to output temperature difference gets larger, the advantage gets less. -- Bill Sloman, Sydney
