Replaced my electric resistance water heater with heat pump, dramatic reduction in energy usage

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.
Got one last September and works really well. Used about 2000 kwh over the winter for central heating for a big house, central Europe. Thats nothing compared to previous use of wood pellets and/or oil.
We also have solar water heating (via vacuum tubes) so water heating is practically free in the summer. Though you do need a large tank to store it.
