What You Should Know about Furnaces and Energy Efficiency
Not all furnaces are created equal. Some furnaces are much more energy-efficient than others, which can save you money on heating in the long run. To get the most out of your investment, it’s important to understand how a furnace’s efficiency is determined and rated.
A furnace’s heating efficiency is measured by its AFUE, or annual fuel utilization efficiency. Inevitably, some of the heat your furnace provides is going to be lost through its chimney. The AFUE measures the amount of heat your house receives against the amount of fuel the furnace requires. This tells you exactly how much heat is lost, and – most importantly — how much of every dollar you spend on fuel actually goes toward keeping you warm. Let’s say we have a furnace with an 80% AFUE rating. This means that 80 percent of the furnace’s fuel goes toward heating your home, and the other 20 percent is lost.
The higher a furnace’s AFUE rating, the higher its efficiency. As of January 1st, 1992, The US Department of Energy requires that all furnaces sold in the US must have a minimum AFUE of 78 percent. Today, thanks to numerous technological advances, furnaces can have an AFUE rating of as high as 96 percent. A rating this high can make a real difference in your heating bills, and is kinder to the environment.
