Furnace AFUE is an energy efficiency rating that measures how efficiently furnaces and boilers can convert fuel to energy. Learn about how a good AFUE furnace rating can affect your heating bills. High-efficiency units are in the 90 – 98.5% AFUE and include features like two heat exchangers and more

The annual fuel utilization efficiency (AFUE; pronounced 'A'-'Few' or 'A'-'F'-'U'-'E') is a thermal efficiency measure of space-heating furnaces and boilers.

AFUE, or annual fuel utilization efficiency, measures how efficiently a furnace converts fuel into energy. A higher AFUE rating means greater efficiency.

Jan 5, 2022 · Annualized Fuel Utilization Efficiency measures your furnace's heating efficiency. Learn what AFUE means, and what a good AFUE rating is for your furnace.

AFUE is a measure of how efficient the appliance is in converting the energy from fuel to heat over the course of a typical year. Specifically, AFUE is the ratio of the furnace's or boiler's annual heat output compared to its total annual fossil fuel energy consumed.

AFUE rating stands for ‘Annual Fuel Utilization Efficiency’. This is a key energy-efficiency rating for furnaces, and it’s most commonly used when evaluating the energy efficiency of gas furnaces.

Sep 12, 2024 · AFUE measures how efficiently heating systems, including furnaces and boilers, convert fuel into heat over the course of an entire heating season. Expressed as a percentage, it represents the ratio of heat output to the total energy consumed.

Feb 2, 2024 · Annual Fuel Utilization Efficiency (AFUE) is a metric that measures how efficiently a furnace transforms fuel into heat for your home, representing the proportion of fuel converted into usable heat.

Sep 18, 2018 · AFUE is a measure of your furnace, boiler, or water heater’s energy efficiency. Keep in mind that electric heat pumps (in heating mode) use Heating Season performance Factor (HSPF) instead. AFUE stands for Annual Fuel Utilization Efficiency and …

Dec 28, 2023 · An AFUE rating above 90% means a furnace has a high efficiency rating. AFUEs between 80% and 89% are considered a mid-tier efficiency rating for furnaces. You can find your furnace’s efficiency rating on the bright yellow tag located on the unit.
