In the last entry I made I looked at how not to find cracks in a heat exchanger. There are ways to find cracks in heat exchangers that do work and can be learned with a little bit of skill and knowledge of where to look. Without a doubt, the only surefire and 100% best way to find a crack is visually. This way there can be no doubt. Although I don’t condone sticking your face in front of a furnace to watch the flame for disturbances, there are other ways to determine this.
