In a heat pump, the heat does not come from the electricity but from an environmental source. The electricity moves and compresses but does not heat anything.

Your usage of dollars indicates you live in the US. I hate to tell you but your definition of "economic" is probably not sustainable. Your price of electricity would probably double or even triple when switching to (cheap) renewables.

Finally someone who recognized that renewables are a magnitude more expensive instead of the usual "muh, renewables are cheaper!" fallacy. Look at the typical price per kWh in Germany (around 32ct/kWh) and tell me again how that is cheap...
