On a typical winter day for those living in cold climates, how much
water (condensation) is produced by a high-efficiency furnace per day?
I've heard ranges from barely anything to 5 gallons per day.

And would this amount to more or less than what is produced by a
central air conditioner?


This from personal recollections. I would guess about a quart per day. Ours
discharged over the driveway and I never saw a ice stalagmite over a foot
tall after several below freezing days in a row.

The AC output will vary greatly with humidity but something around 5 gallons
per day would be realistic here and now.

Thanks for the input. Have you noticed any discoloration of your
driveway? I've read that the water run-off from condensation of a gas
furnace is acidic, with a pH roughly the same as orange juice.
