Thanks for the VERY informative information! "Hyper heat" seems to have
become a common label applied to air source heat pumps that can produce
heat down around zero F; other brands than Mitsubishi offer them.

There has to be a catch. How can they efficiently extract heat from
such cold air? I'm eager to learn details and see evaluations.
Here is one explanation:

Just depends on the system involved. 0F is WAY above absolute 0. It's
quite possible to make a heatpump that works with a large temperature
difference. It's not going to get a 20x factor like most, but I'm quite
sure that you can make one that is > 1.
Bingo! :-) I

They can't, I don't care what they say. The laws of physics still apply.
The "heat" that is being discharged might be 60F which is hot compared
to 0F. They would have to circulate thousands of cubic yards of 0F air
to obtain even a tiny amount of "heat".

They can indeed extract heat, but I'm not so sure "efficiently" necessarily
applies.
I have a Mitsubishi Mister Slim M series
