Ah, I see. I figured they'd keep the input energy constant because otherwise you're not saying much at all (you could figure that the efficiency plummets and you'd be better off with a space heater).
- mlyle 4y agoIt's possible. Also possible it's barely outperforming the space heater at the lower temperature and input power has increased. They've not told us enough.
- coryrc 4y agoThe energy input goes down because it physically can't run a differential high enough to get full heating output. They could choose the lowest temperature, find it's power input, then fix it at that amount. But at low temperatures the concern is usually less "efficiency" and more "am I going to freeze to death", because in most of the cold areas temperatures aren't usually that cold for that long (though in others it definitely is, and if you're running at 1.6 COP for a significant amount of time, you're better off with more insulation than a heat pump).
