What is an AFUE rating?
The Annual Fuel Utilization Efficiency rating (AFUE), is the standard measure of a gas furnace or boiler’s efficiency in converting fuel to energy. The higher the rating, the more efficient use of fuel, For example, a 90% AFUE rating means that 90% of the fuel used offers warmth for your home and 10% escapes with the exhaust.
