80 Percent Afue Gas Furnace

A standard efficiency furnace provides 80 annual fuel utilization efficiency afue.

80 percent afue gas furnace.

These days 95 afue is a common rating among new gas powered furnaces. In this type of furnace 20 of the energy produced by natural gas is expelled as exhaust. This gas furnace has an afue rating of 80 which means that 80 cents of every 1 00 of heating energy expense warms your home. That means a 95 afue furnace will cost less to run than an 80 afue furnace.

For a 90 percent afue furnace it operates using multistage burners that sense the heating needs of a home and operate accordingly. High efficiency furnaces offer 90 or more afue.

But besides the level of efficiency another key difference between the 80 afue and 95 afue furnaces is that they operate a little differently. So a 95 furnace is more efficient than an 80 furnace. The higher the afue percentage the more efficient a furnace is at converting gas into heating energy. Two stage convertible multi speed ecm gas furnace 80 afue heating input.

It s likely that they will scale back production of 80 afue gas furnaces and start building more furnaces with a higher efficiency rating.
