Even if electricity is generated with gas, and with the energy lost in the generation and transmission, with a really good heat pump and optimal conditions, it could outperform a gas furnace, because a heat pump can be more than 100% efficient. https://en.wikipedia.org/wiki/Coefficient_of_performance >The efficiency of air source heat pumps is measured by the coefficient of performance (COP). A COP of 4 means the heat pump produces 4 units of heat energy for every 1 unit of electricity it consumes. Within temperature ranges of −3 °C (27 °F) to 10 °C (50 °F), the COP for many machines is fairly stable. >In mild weather with an outside temperature of 10 °C (50 °F), the COP of efficient air source heat pumps ranges from 4 to 6. https://en.wikipedia.org/wiki/Air_source_heat_pump |
