Century old churches were never heated. The attendees kept their winter coats on and everything was fine.Forced air heating does dry air and reduce humidity. Radiant no.
Dealing with humidity is a ***** in the north. Above 30 causes windows and doors to freeze shut, locks freeze, and a lot of mold issues in older houses. I have to dehumidify my place to keep things manageable.
Then they added heat and the rise in temperature lowered the relative humidity. Wooden objects warped and split. The snow melted off the roof and caused eaves and downspout issues. Leaky downspouts saturated walls causing deterioration.
