Cracked heat exchanger leads to modern furnace
Until last winter, I had never given much thought to how the furnace operated or the importance of the heat exchanger.
I didn’t realize exactly what a heat exchanger is.
I’ve since learned that it is made up of coiled tubes that contain the tepid gasses produced by the combustion process. When the blower starts up plus cool air flows over the heat exchanger, the air becomes warmer without coming into contact with dangerous gasses. The heated air then rises into the plenum, which is a box made out of sheet metal that links to the supply ducts. From the supply ducts, the air gets spread throughout the house. The combustion byproducts get sent through the flue pipe plus safely delivered outside by way of the chimney. The heat exchanger is the barrier between the breathing air plus carbon monoxide, carbon dioxide, nitrogen dioxide, sulfur, VOCs plus more. A correctly operating heat exchanger plus ventilation system ensure that none of those combustion gasses ever get circulated into the living space. Because I failed to keep up with regular professional maintenance for the furnace, the accumulation of dust on the filters, blowers, coils plus heat exchanger made it hard for air to pass through the system. The heat exchanger hot plus developed a small crack. Finding a heat exchanger to match my particular furnace proved impossible, plus I had no option but to update the entire heating unit, neglecting annual upkeep ended up costing me a good deal. I now have a brand modern furnace, plus I’m taking unquestionably good care of it.
