I would think that the heat itself would dehumidify the air somewhat but with all the moisture on the ground up that way maybe not. I heat my shop, 12' x 24' with one of those dual panel jobs from Coleman that fastens to the top of a propane cylinder. Will heat the place to over 90 degrees if necessary as the shop is insulated with R11. If your firewall is stripped you may want to warm it up before painting with one of your heat sources. Just remember not to spray with a source of ignition anywhere in the room.
