Annualized Fuel Utilization Efficiency (AFUE)
The thermal efficiency measurement of combustion equipment, such as your furnace or water heater, is referred to as annual fuel utilization efficiency (AFUE). Pronounced ‘A’-‘Few’ is different than the true thermal efficiency as it is a measurement of season-long, average efficiency as opposed to a steady-state, peak measurement.
