Why Is a High AFUE Rating a Good Thing?

Why Is a High AFUE Rating a Good Thing?

Why Is a High AFUE Rating a Good Thing?

If you’ve shopped for a furnace, you’ve probably heard the term “AFUE” tossed around as a measurement of how good a given model is. A higher AFUE rating often means a higher price, and you might naturally wonder what exactly you’re getting for that additional cost. Here in Mesa, AZ, heating repair services can discuss the matter in detail with you, but we have a short version right here. Why is a high AFUE rating a good thing? Read on for the answers.

AFUE stands for Annual Fuel Utilization Efficiency, and it’s a means of measuring your heater’s overall efficiency. To obtain the number, you divide the amount of energy the heater takes in to do its job by the amount that actually goes into heating the home. You’re left with a percentage rating, representing how much of the heater’s energy it actually uses for heat. The rest is lost to waste and inefficiency: energy that you have to pay for even though you don’t end up using it.

That’s why a high AFUE rating is a good thing. It speaks to the quality of the furnace you’re buying and can constitute real savings from month to month on your home energy bills. Say you have a unit that has an AFUE rating of 50% and another one with an AFUE rating of 90%. You need 50,000 BTUs to heat your home. With the first heater, you would need to generate 100,000 BTUs of energy for that 50,000 BTUs, while with the second heater, you’d only have to generate 55,555 BTUs. That’s a difference of almost 45,000 BTUs: almost double the amount of energy you needed to heat the home in the first place!

Apply that from month to month and you begin to see why a high AFUE rating is a good thing. You should ask about the AFUE rating any time you’re considering adding a new heater, or look for the EnergyStar logo which indicates ah ANFUE of 90% or greater in gas furnaces and 85% or greater in oil furnaces.
