i heat with wood, and solved my humidity probs with a add on whole house humidifier for my furnace.
if you have a forced air furnace, a $70 add on humidifier will do wonders. it has a hose that you tap into your water supply with, so you never need to fill it, it fills itself. it works kinda like a carburator float bowl.
about 4 hrs. of sheet metal cutting, measuring, some screws, and some patience is all thats required to install the thing, along with an electrical outlet.
i just run the furnace fan during the day, and the house stays plenty comfortable, along with the cigars.
hope that helps.
