"Still has a COP of 1.0" implies it is still doing something is all.
It would be clearer to just say that it works down to 5.
I'm not in the coldest regions and would be using resistive heat many nights of 3 months with that performance.
- PaulDavisThe1st 4y agoMitsubishi's approach is to avoid resistive heating, and instead drop COP to 0.85 at -13F If the unit is sized correctly, this will provide adequate heat, albeit less efficiently than resistive heating would. If you live in an area where most of the heating hours are at 5F or below, yes, resistive would make more sense. But where is that?
