Too Much humidity

[mike31154]

That's strange, and you have an HRV. One of the colder evenings around here these days (-8C) and there's no sign of moisture on any of my windows this morning. 77 gal sumpless with open top sitting within a few feet of two windows. I do not have an HRV. I guess sometimes having a leaky old house has it's pros. My furnace is not the latest, but not all that old either. There is no humidifier on it and the house feels comfortable humidity wise. I guess my tank is sized almost perfect for winter humidification, it evaporates around a gallon a day, give or take. Hygrometer reads 53 right at the moment, which according to the scale on it, is on the low side of normal.
