efficiency (AFUE) rating. AFUE, the most widely used measure of seasonal thermal efficiency for residential-sized heating equipment, is defined as the amount of useful heat delivered from a unit into a heating system for distribution, compared to the amount of fuel supplied to the unit on an annual basis. Units with efficiency levels in excess of 90% generally rely on extracting
