Did You Know?
Whether gas or oil, ENERGY STAR qualified boilers use about 6% less energy than a standard boiler.
Overview

ENERGY STAR qualified boilers have an annual fuel utilization efficiency (AFUE) rating of 85% or greater. They achieve greater efficiency with improved features, including:
- electric ignition, which eliminates the need to have the pilot light burning all the time
- new combustion technologies that extract more heat from the same amount of fuel
- sealed combustion that uses outside air to fuel the burner, reducing draft and improving safety
