I have three heat pumps with 6 outlets, costing $24000, but I have not used them when the temps are 15 F or less, because then it is much less costly/kWh to use my three propane stoves that need no electrical connection.
My total energy savings have not exceeded $200 per year, for each of 5 years
If amortization costs are applied at 6% over 15 years, I lose $2000 per year

I will lose more, if there are maintenance costs
