For Electric Customers
Heating systems are measured by their efficiency in Annual Fuel Utilization Efficiency (AFUE). This industry standard measures the percentage of heat output against the amount of energy input. Electric furnaces use nearly 100% of the electricity for heat, which means they operating more efficiently than fuel-burning systems because they produce no combustion byproducts. The U.S. Department of Energy rates all-electric systems at 95% to 100% AFUE.
If electricity is the only option for energy, electric heat pumps are preferred in most climates, as they easily cut electricity use by 50% compared to electric resistance baseboard heating.
