The Lennox 99W41 Aluminum Heat Exchanger 150K is the workhorse behind your furnace's heating power. Crafted from durable aluminum, this essential component efficiently transfers heat from combustion gases to the air circulated throughout your home. Its impressive 150,000 BTU capacity makes it ideal for larger heating systems. Imagine a river of hot air flowing through a network of tubes. That's essentially how the 99W41 operates. Hot combustion gases travel through one set of tubes, while cool air passes through another. Heat is transferred through the thin aluminum walls, warming the air without mixing the two streams, ensuring safety and efficiency.
