For those who use a cast-iron woodstove humidifier...
I've been wanting a cast-iron humidifier (similar to this one) to put on my woodstove, and received one for Christmas. But now that I've got it, I'm not sure what to do with it.
I used it for a couple of days, about 2/3 filled with water, and noticed streaks of rust on the inside where the water was. Could this be because the stove wasn't burning very hot? (Temp was 50 outside.) Now it's colder and the stove is hotter.
I assume the water is supposed to boil, but I can see myself filling it often as the water boils away. And I won't want to leave it on the stove if I leave the house for any length of time.
Tips on using this would be appreciated--thanks!
