Terry asks,
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?
I’ve heard of some people needing to use a dehumidifier in the winter to keep some of the moisture down.
A dehumidifier will remove the moisture, but keep in mind that the other combustion byproducts will saturate the room. For example, should the gas burners malfunction, they could produce a toxic level of carbon monoxide. If you keep using this ventless fireplace (which I do not recommend) I’d also recommend installing a plug-in carbon monoxide detector.
We can’t afford to replace our ventless gas wall heaters so what is another solution?
Tim’s reply is right on. Use a dehumidifier. That will solve the problem. I had the same problem. Dehumidifier done the trick.
Just dont use it.
