Trane Gas Furnace Efficiency Factors & Fuel Purity
Trane Gas Furnace Efficiency Factors – This is a Trane gas furnace. It is also called a Trane 90 plus gas furnace because it offers efficiency levels up to 90 percent plus AFUE (rating). Gas or oil furnaces generally cannot achieve efficiency at 100% because of impurities in the fuel including moisture. This is the reason why no fossil fuel furnace sold has a rating of up to 100%.
This biggest impurity in many fuels is moisture which is difficult to remove because it is in the distribution and storage places where the fuel is distributed and stored. If these impurities were removed from the fuels before they have been introduced to the furnace the cost of the fuel would be much higher and the cost to benefit ratio would not be effective.
