Description
The Lennox 11X38 Heat Exchanger Assembly is an essential part that is used to ensure the heat exchange within Lennox brand of gas furnaces. This 2-stage heat exchanger is built from aluminized steel and ensures high heating efficiency and pleasant climate. The hot combustion gasses from the furnace combustion chamber pass through the aluminized steel tubes of this assembly. This warmed air is then distributed throughout your home using ducting systems that may also be zoned. The innovative 2-stage operation means that during moderate ambient temperatures, the furnace can work in low output mode, which might bring enhanced efficiency and comfort compared to a furnace with only one stage.
