Getting to Know Your AFUE

Every one is talking about energy efficiency these days and that too can relate to your furnace. How do you measure the efficiency of your furnace? With an AFUE rating. As defined by TRANE, “The Annual Fuel Utilization Efficiency (AFUE) is a measure of a gas furnace’s efficiency in converting fuel to energy, by projecting the average thermal efficiency for a complete heating season. A higher AFUE rating means greater energy efficiency.”

Since the FTC requires new furnaces and boilers to display their AFUE, as a consumer you will always be able to compare the efficiency of different models when shopping for a new furnace. As of right now, the minimum AFUE available is 78%, with the exception of those designed for mobile homes.

How is the AFUE calculated? The percent of fuel that becomes heat in your home is the AFUE rating compared to the remaining percentage which escapes from your home through the chimney or other outlets. In laymen terms, the more energy productively used to heat your home the better. Makes sense, right?
