Customer Concern, Dry Air

in THE MAIN WALL
I have a customer who thought a hydronic heat fan coil
would rob less moisture from the air than a gas fired forced air furnace. The house is pretty tight, I would think that moisture goes in , moisture goes out on either one. Right?

    Neither

    will remove humidity so you are correct. The only way a warm air system can change the absolute or "specific" humidity in a house is by pressure imbalance whereby it draws in more dry outside air than normal infiltration would allow.

    ANY house or space which is heated by any means from a cooler state will experience a drop in relative humidity as the air is able to hold more at warmer temperatures.

    But either process in itself, going through a furnace or a hot water coil will not remove humidity, just "give it more room".
