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.
It’s great for hot water. It’s not so great for clothes. They’re much more prevalent in Europe as you can use the chilled side of the circuit to condense moist area, eliminating the need for venting, and they use less energy. They also take hours to dry clothes, and those clothes often still need to be hung to dry for awhile afterwards. We had one, we now just hang our clothes to dry.
