Purchasing Energy-Efficient Residential Gas Boilers

FEMP's acquisition guidance for residential boilers and the associated ENERGY STAR efficiency requirements apply to natural gas boilers with an input rating of less than 300,000 Btu/h. Commercial boilers (i.e., those with an input rating of 300,000 Btu/h or greater) are excluded. This acquisition guidance was updated in June 2021.

What is a Condensing Gas Boiler? | U.S. Boiler Company

Traditional gas boilers burn natural gas or propane to heat the water in a home heating system. These boilers are vented to the outside via a chimney flue or vent pipe. A boiler's efficiency is measured by annual fuel utilization efficiency (AFUE). This is the ratio of the boiler's annual heat output compared to the total annual fossil

Chapter 5: Residential Furnaces and Boilers …

Taking the ratio of a boiler's annual heat output compared to the total annual fossil fuel energy it consumes generates this. An AFUE of 80% means that 80% of the fuel energy becomes heat for your home, and the remaining 20% either escapes through the boiler into the space where the boiler is located, or up through your chimney.
