There’s a massive difference in capability and efficiency and usability of heat pumps. The crappy ones don’t even work below freezing. The good ones can operate even down to -20F efficiently, even air source. And ground source ones don’t have a hard limit at all (although they face a similar wide difference in capability).
Low effort cheap heat pumps are gonna do more harm than good in that they’ll convince people that heat pumps suck.
It’s like the difference between a Tesla and a lead acid golf cart. Both are “electric” “cars”, but there’s vastly different capability.
