Question: What Is The Difference Between An 80% Efficient Furnace And A 90% Efficient Furnace?

Should I buy 80 or 95% efficiency furnace?

A standard efficiency furnace provides 80% annual fuel utilization efficiency (AFUE).

In this type of furnace, 20% of the energy produced by natural gas is expelled as exhaust.

High efficiency furnaces offer 90% or more AFUE.

So a 95% furnace is more efficient than an 80% furnace..
