How to improve the energy efficiency of boiler systems

Jan 08, 2016 · New boilers under 300,000 BTUH are required to display an annual fuel utilization efficiency (AFUE) rating. This is essentially a ratio of heat output to the fuel used to power the boiler. For example, a rating of 85% means 15% of the energy in the fuel wasn't used for generating heat. This is also thought of as fuel-to-steam efficiency.
