What Is The Furnace Heat Exchanger?
The non-technical definition is that the heat exchanger is a series of tubes or ribbons inside your furnace that form a chamber of sorts, designed to separate the hot gases and flames of the heating system from the forced air passing over it, and being spread throughout your home. When you furnace ignites, a flame is generated. That flame and the hot gases are routed into the heat exchanger, and eventually out the flue, or exhaust system. The tubes or ribbons naturally heat up as the unit runs. When the blower turns on, the air is forced to pass through or over the heat exchanger, thus warming the air and sending it through your home in the form of heat!
