AFUE Energy Efficiency

BENEFITS OF A NEW FURNACE

Older furnaces have an AFUE range of 56% to 70%, which means that between 35% and 50% of the natural gas goes to waste along with 25-35% of the electricity. New high-efficiency furnace systems typically have AFUE ratings of well over 90% and can be as high as 97%. Because of this great difference in fuel efficiency, these new high-efficiency furnaces can pay for themselves in only a few years.

30 yr old 78% AFUE
Conventional vent furnace

outdated by TSSA, 18% current AFUE

12 yr old 88% AFUE
ABS vent furnace

outdated by TSSA, 64% current AFUE

Brand New 95% AFUE
PVC venting furnace

TSSA mandated, 95% current AFUE

A furnace loses 2% efficiency annually

The analysis is the age with a loss in 2% efficiency is : 2(%) X 30 (age of equipment) = 60% loss in efficiency. So, then you take the efficiency loss subtracted from the standard, which is 78% – 60% = 18% current efficiency rating. Furthermore, an upgrade to high efficiency would mean a 78% boost in savings for the homeowner’s energy bills.Get a Nest Learning Thermostat at no cost.
