As we used them for heating we have no issue with the actual heating ,, its even in the rooms , responds quickly , etc but I'm not sure about the efficiency heating with these heat pumps .
I,m sure that as the outside temp approaches zero you may want to be swapping over to the oil furnace as the more temp difference the less efficient these get .

I believe SteveO had the "Hyper Heat Pumps" installed which are super efficient well below zero. I believe they offer 100% efficiency at 5°F and 73% capacity at -13°F. The standard heat pump which is what I have (used primarily for cooling) start losing efficiency around 30 degrees.
For my seasonal camp I absolutely love mine and wouldn't be without them!!
