What you really need is a separate exhaut to the OUTSIDE-NOT THE ATTIC.
Excessive moisture in the attic will cause other even more serious
problems. Your attic should have a thermostatically controlled exhaust
fan. For the basement, you also need to provide comubustion air for the
furnace so it doesn't draw inside air to heat, AND VERY IMPORTANTLY DOES
NOT CAUSE EXHAUST BACKFLOW INTO THE HOUSE! THIS COULD BE FATAL!!!!
Simple cure is to close the doors to the basement an open a basement
window just a crack all year round.

Please be carefull!


I also turned off the exhaust. I lose 4 gallons of water per day from
the tanks. That isn't all that terrible. Although the windows are
misted over for a little while in the morning, I don't think there's
real damage. Usually, houses around here suffer from excessive dryness
during the winter, so maybe it's even a good thing. Shouldn't the
installers of the gas system have understood the problem when the
furnace wouldn't work? They saw the downdraft from the chimney and
assumed it was clogged, for which we paid another pro to come out and
tell us it was clean.

Thank you again.
