We have a mini-split heat pump, they are only considered a 3 season unit. They stop being efficient at about -5C (23F) and pretty well quit working at -8C (17F).
As for heating, old ones are about 8 times more efficient than baseboards and new ones are up to 15 to 20 times more efficient.

Not putting miles on your car is like not having sex with your girlfriend, so she'll be more desirable to her next boyfriend.
