The energy savings below are estimates only that serve as guidance in a homeowner’s furnace purchase
- Select the efficiency of your current furnace. (See help below.)
- Enter your exact or estimated yearly gas costs*
*Rather than guessing, we recommend taking your current yearly heating bills to determine your estimated future operating cost savings
Need help determining your current efficiency? Check the flue pipe coming off your furnace. (This is a 2-5″ diameter pipe exiting your furnace that vents waste gas.)
If the flue pipe is metal your furnace is 80% or below. If the flue pipe is white PVC plastic your furnace is 90% or greater.
The chart below helps determine your likely efficiency if you have a metal flue.
What does the ‘%’ mean? A furnaces efficiency has an AFUE rating which is measured in a percentage.
The higher the percentage, the more efficient the furnace is. A more efficient furnace costs less to operate as shown in the table above.
