We have a GE geospring WH. Got it on a closeout ($700) at Lowes 2 years ago, and the POCO 'rebate' paid for 100% of it (I still got stuck with sales tax though, but the federal tax credit just about covered the sales tax, so close to 'free')
Best I can tell it is just 1/2 TON HP. 550W, 3.2 COP.
Only the 2 of us at home now, we run it in HP mode only.
Installed about 2 years ago, have a separate wh meter on the WH.
Installed just under 2 years ago in Sept, it has used 723 kW-hrs in 2 years, average of about 11 cents a day for hot water. Installed in the 'unheated*' basement where temperature is in the low 60s most the year.
2 or 3 times a year when we have overnight guests we do set it for 'demand', otherwise the resistance heaters are never on.
*WSHP compressor is in the basement as are only partially insulated ducts, so there is some basement heat.
I did build a box around the tank area and added R-22 insulation.
