But besides the level of efficiency another key difference between the 80 afue and 95 afue furnaces is that they operate a little differently.
80 percent afue gas 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.
So a 95 furnace is more efficient than an 80 furnace.
A standard efficiency furnace provides 80 annual fuel utilization efficiency afue.
For now you can buy an 80 efficient gas furnace.
For a 80 percent afue furnace the gas burner is designed to run at optimal speed throughout the heating process.
While this doesn t matter on the coldest days it isn t the most efficient process on milder days.
In this type of furnace 20 of the energy produced by natural gas is expelled as exhaust.
These days 95 afue is a common rating among new gas powered furnaces.
A solid reliable performer.
That means a 95 afue furnace will cost less to run than an 80 afue furnace.
This makes sense because consumers are demanding greater efficiency to fight high fuel costs and to be more ecofriendly in heating their homes.
An afue of 80 means 80 cents of every dollar spent on gas goes directly toward heating your home.
For a 90 percent afue furnace it operates using multistage burners that sense the heating needs of a home and operate accordingly.
That can mean potential savings of hundreds of dollars per year when compared to an older furnace.
High efficiency furnaces offer 90 or more afue.
A standard efficiency furnace has an afue of.
