Concerning Health issues you Relative Humidity should be around 50-60%
And yes when is cold outside "demand" for Humidity will be greater then if
is warm.
Because your furnace is displacing RH or taking it out through your smoke
stock.

I'd say 50% is the upper limit when it's moderate temps outside.
When it's below zero, like Philo has, I'd say 30% or so is tops,
unless you want water condensing at windows, inside walls, etc.



The recommended settings are


-20F 15% humidity
0F 25%
+20F 35%


Exactly. It needs to back off the lower the outside temps.
And I presume you have the outside temp sensor that
automatically adjusts it? That is a great feature.



I don't have an outside temp. sensor, but that's OK I like to fiddle
with things.


First off, I've improved things quite a bit because I did not have the
water supply stop-cock opened all the way so now with the extra water
flow, the humidity is up almost to normal.

I've been reading up and see that I have a "flow-through" type
humidifier which is not efficient in that more water goes down the drain
than into the air.

If I decide to replace it, the "drum" type is supposed to actually put
all of the water into the air.


Also: a few years back I replaced the motor and am pretty sure I put the
fan on correctly but now I wonder which way the air is supposed to flow.

Will have to double check but I think I have it set to blow directly
into the hot air plenum. I can't imagine reversing the air flow would
make a difference???
