Yes, vents are fine, humidifier is off and disconnected. Furnace is HE, so direct vented outside. Same with on demand HW). I re-did the insulation, siding, some of the house wrap and closed up loads of massive holes all over. After that my humidity went way up. I've watched the water meter and it doesn't run unnecessarily, so I can't find any source other than humans and cooking(and my wife buying too many plants, but that isn't going to change). From my understanding, most new houses are so well sealed they have humidity issues without an ERV/HRV. So I figured that's where I am at now. I could be wrong. Perhaps going form HW tank venting up the chimney to direct also reduced a path for humidity to escape?
