This is the heat exchanger on a 90% efficiency furnace and understanding how it works matters 🔍 When the flame ignites, it travels through the exchanger while the exhaust system pulls combustion gases safely out of the home. That process is what keeps carbon monoxide from entering your living space. What we’re pointing out here is heat stress. That discoloration you see shows where cracks are most likely to form over time. Once cracking starts, safety becomes the concern, not just performance.
