What is an AFUE Rating and How is It Measured?

“What is an AUFE rating and how is it measured?” That’s perhaps the most important question you can ask when installing a new heater. Spring is here and with it comes an ample opportunity to replace your old, inefficient furnace with a new one.  If you’re looking for a new furnace, Nashville, TN has plenty of qualified heating system services to help. But it’s beneficial if you understand the variables involved in a new purchase, especially the AFUE rating, which could save you a great deal on monthly costs.

AFUE stands for Annual Fuel Utilization Efficiency ratio. It’s measured as a simple percentage, determined by dividing the amount of energy the heater uses with the amount that actually goes into heating the home. (The rest of it is wasted in inefficiency.) So a heater with an AFUE rating of 90% spends 90% of its energy on heating the home, and so forth.

The equation is simple enough, and as you may have expected, furnaces with a higher AFUE rating tend to cost more than those with a lower rating. That’s because more efficient furnaces will do the job with less energy, which will save you money on monthly heating bills when you use it. Older furnaces tend to lose a lot of their efficiency as they age. Parts become worn out and the system as a whole won’t do the job quite as well as it once did. In addition, furnace technology makes steps forward all the time, and new furnaces are apt to be more efficient than older models by default.

All of which is a roundabout way of saying that if you purchase a new furnace, make sure it has a higher AFUE rating than your old one if you can help it. It will save you plenty of money on your monthly bills and help recoup the cost of the initial installment.
