AFUE - Annual Fuel Utilization Efficiency
This is the rating that all heating systems are given by the federal government, and rates the efficiency of each manufacturers system. It is similar to the EPA ratings for gas mileage on your car. The higher the AFUE rating, the higher the efficiency, and therefore, the lower your heating bill. Gas systems run as high as 94% and oil as high as 86% AFUE.
