Consumer question:
When installed, should the unit attached to the cold air side of the furnace or on the warm air side? It does not make sense to add water vapor on the cold air side, then heating the air and burning off some of the humidity.
Aprilaires' response:
It does not matter if the 700 is mounted on the hot air side, or the cold air side. The only requirement is... if installed on the cold air side, you have to run hot water to the humidifier.
Having humidified air put into the cold air return, then into the furnace to be reheated and put out to the home, will not hurt the humidity level. It will not burn off any of the moisture.
