I heard that when one has a humidifier installed directly into one's
furnace, the humidifier will cause the heat exchanger to corrode much
faster
than without a humidifier. Is this true?

If the humidifier is an atomizing type and the water sprays on the HX, it
will rust the HX out fast.

If it's a vapor type humidifier, like an AprilAir, it won't cause faster
rusting.


I'm not sure a guy who sells furnaces is going to give an honest answer.


Most of us do give honest answers. Even Davey (HVAC Fella) gives honest
answers, but they are honest to him only. The answers are honest, but not
correct.
