A friend asked me about humidifying his new home with wood floors, walls and ceilings. Its located in central Michigan and is about 1000 sq. ft. He is on the road for weeks at a time and can't fill and maintain a room humidifier. He has in-floor heat (no ducts). Is there something he can mount on a wall and hook a water supply line to which can automatically humidify his home while he is gone?
