Furnaces and Boilers | Department of Energy

Apr 30, 2021 · The size of the boiler in the context of efficiency is its heat output, measured in kW. The higher the heat output of the boiler, the more energy it will be using when it's switched on. In most cases, larger homes with more radiators and more bathrooms will need a larger heat output than smaller ones.

Boiler Efficiency Testing Objectives

applications, different performance standards are used to rate a boiler's efficiency (refer to Table 1). For example, the DOE's (U.S. Department of Energy) National Test Standard requires boilers with capacities less than 0.3 million Btuh be rated to an Annual Fuel Utilization Efficiency (AFUE) (HI 1999).
