Bosch Compress 3000 Heat Pump
Costs less than one dollar a day to run for 3 -4 person family
We are a family of 3 , every other week 4 , persons. Our daughter has a bath every day. The power usage can be tracked on the heat pump itself, so I know for sure my figures are right. We spend about $25 monthly on electricity. Previously we paid $50 monthly on fixed line charges for gas + $25 for usage. The only issue we had was a slowly leaking pipe coupling at bottom of cylinder which is fixed now under warranty.
