Afue Sentence Examples
This will lower the amount of gas you require to run the furnace, making even a furnace with a slightly lower AFUE rating more efficient.
The measure used to determine how well a furnace was running is known as an Annual Fuel Utilization Efficiency (AFUE) rating.
Today's high efficiency furnaces are available with an AFUE of up to 96.7%, which translates into a serious savings on your gas bill each winter.
And while 78% AFUE is a significant improvement over a 20 year old furnace you may have in your home, it's not classified as high efficiency by the DOE.
You need to see the actual AFUE of the furnace you are considering.
You may find that purchasing a unit with one or two percentage points lower AFUE rating will actually save you more after the installation costs have been taken into consideration.
