It's called Coefficient Of Performance or COP heat pumps are more like 2 or three.I’ve been hearing about these high efficiency heat pumps and they seem to good to be true. I’ve read for $1 of input you can get $7 of energy out of them or something crazy like that. I don’t see how that’s possible. I get how they work, but it just seems to good to be true.
Considering electricity is 100 percent efficient that's pretty good . Most pumps will only be edged out by the most efficient natural gas furnace. That are much better than propane or oil. As far as cost of running one.
