I havn't known that to be a problem. The condensate does tend to be strongly
acidic. I put in a 90 percenter in my own home, I think it was year 2004. It
has been repaired once since then. The draft inducer fan went dead, and I
had to go buy another one.

Flue gas exhaust from a furnace contains water

Condensing furnaces (with their extra heat exchanger, sensors,
electronics, condensate handler, etc) isin't much more expensive than a
regular efficiency furnace?


What's condensing in a furnace?? Never heard of that before.
