When air is cooled it can't hold as much and that is why condensation is formed. On a hot day your favorite cold beverage container sweats. That is because the air surrounding the can is cooled and can't hold as much water. It then condenses on the container.

Now that finally made sense to me. So if I understand correctly; say the humidity in my house to start is around 60% at 65° and swmbo tends the fire all day. She keeps the main floor over 100° cause she refuses to open a window because its 30° outside, and the fire being as hot as it is 900° +/-. The air being heated so much makes it so there has to be drastically more moisture to maintain the same humidity in the house.

So if I were to run a humidifier on top of the 10 gallons of water being heated on the stove a day. The humidity should be more reasonable.

I think that you got the general idea but I would ignore the stove temp itself unless you were measuring the 800 degree air 1 inch from the stove.
