5 Factors Killing Your Industrial Boiler Efficiency & What

Jan 08, 2016 · Understanding Residential Boiler Efficiency Ratings. Boiler efficiency is measured by annual fuel utilization efficiency (AFUE), for units under 300,000 BTUH input. The Federal Trade Commission requires new boilers to display their AFUE so consumers can compare heating efficiencies of various models.
