I am looking into solutions for our historic house museum's humidity problem. While dehumidifiers work well-enough in the summer, I am having trouble finding free-standing humidifiers that can handle the capacity I need in the winter. So now I am looking into duct-mounted humidistats. Is anyone using these systems? What has been your experience? Any other options you care to share? Thanks! Chris Christopher M.
