I recently installed an Emporia Vue with monitoring for the individual circuit my water heater is on. It captured the very significant difference in energy usage from replacing resistive heat with heat pump.

Yeah, I seem to be mistaken and you are right, -25 is accurate for heat pumps for room heating. But the Nibe F110 is a heat pump water heater that works down to -10C, and Indol have a few models that says down to -12C. Still quite good!
