0805 Maximizing Temperature Differences - Heating - Condensing Furnaces -

Image Text: In most high efficiency furnaces, heat is transferred from the coolest exhaust products to the coolest house air > this maximizes the temperature differential from beginning to end of the heat exchanger for the best flow of exhaust gases and also maximizes heat transfer to the house air > supply plenum > combustion air > hot house air > primary heat exchanger > exhaust gases > secondary heat exchanger > house air blower > cool house air > induced draft fan > exhaust vent
