   i think so.

   The ERV will be adding a little heat to the incoming air then you can add humidity downstream.

   Make sure you monitor the RH in the building so it stays 30-50% i'd say.

   Does the ERV run on a timer or humidistat? If run on humidistat turning on the humidifier might make it run too often. That might be fun to see which would win. Let us know.

   It runs on a timer. My ERV guy just replaced the motor on the new system. He's thinking about it, too. If it'd work, would be nice.

   Look for a humidifier that can be fed hot water. (Most AprilAire units can accept hot water, other brands vary.) Hot water increases the effectiveness of the unit at low air temps.

   You'll have a little trouble deciding where to place the humidistat. Probably on the exhaust duct is the theoretically best place.
