Compare the fuel cost of gas, resistance and heat-pump heating.
Gas is measured in therms at furnace efficiency, while electric resistance converts the BTU load to kilowatt-hours. A heat pump divides that electricity by its COP. Gas prices and electric rates vary, so a side-by-side comparison reveals whether a heat pump actually beats the local gas bill.
Gas vs Electric Heat
Gas = therms / efficiency x price; electric = kWh x rate (/ COP for heat pump)
Gas = therms / efficiency x price; electric = kWh x rate (/ COP for heat pump) Gas is measured in therms at furnace efficiency, while electric resistance converts the BTU load to kilowatt-hours. A heat pump divides that electricity by its COP.
