I've had an Aprilaire humidifier on my furnace for quite some time and
it does work. but recently I got a hygrometer to check the actual
humidity in here, and see that when it gets below zero the humidity in
the house is only about 12%. In warmer weather the humidity is up where
it should be,,,in the 25% to 35% range.

I suppose I could just get a stand-alone unit but was wondering if my
on-furnace unit could be improved any. The fan is working, the water
flow is fine and I put a new element in it.



I've found that in cold weather I have a limit on the amount of
humidity because above that limit (which varies with outside temp),
the humidifier just causes condensation on windows.
