Meanwhile, generating heat with resistive heating is literally just the cost of wires. And the electric current you need to run through them. Resistive heating has a COP of 1.0 by definition. A modern, cold climate, air source heat pump can achieve a COP of 4.0 or higher at temperatures down to -15C (5F). This means 1/4 the winter heating bill for heat pumps over resistive electric. Where I live (Canada) the winter heating bills are far higher than the summer cooling bills, despite our humid summers with heat waves reaching 30C+ (86F) for weeks at a time.
