Ventless Natural Gas Heater Moisture Problem

Submitted By

We live in mid-Michigan, and a few years back we had an 8’ x 10’ year-round leisure room built onto our home. The house wall was drywalled and painted, and the three outside walls have slider windows and a set of patio doors. We installed a ventless natural gas wall heater and added a wood enclosure to give it a fireplace look. In the winter months, we have a problem with the room “sweating” and dripping onto our furniture from the ceiling. Do you have any suggestions for us?
