> I dont understand how heat output from a heat pump vs heat output from a gas / oil / wood burner / resistive heater are at all different. A gas/oil/wood burner are not 100% efficient in creating heat, and release carbon into the atmosphere. A resistive heat is at most 100% efficient: all the electrons go to making the coil glow, like old school light bulbs. So 1 kW of electricity is 1 kW of heat (which has some BTU equivalent for old fashioned folks). A heat pump does not create heat, but moves it from one place to another with refrigerant and pumps. So 1 kW of electrical usage can move 3 kW of heat at times: * https://en.wikipedia.org/wiki/Coefficient_of_performance https://en.wikipedia.org/wiki/Coefficient_of_performance * https://energyeducation.ca/encyclopedia/Coefficient_of_performance https://energyeducation.ca/encyclopedia/Coefficient_of_perfo... So if you input 1 kW of energy, do you want 0.9 kW of heat out (carbon), 1 kW of heat out (resistive), or >2 kW of heat out?
