One of the problems with wood heat is make up air. People often complain a wood stove dries out the air in a house. What is actually happening is the air the stove requires for combustion is drawn from within the envelope of the house. Air to replace that comes in through cracks, gaps and leaks from outside and, at low temps, that air is quite low in humidity.
The way around this is to have a dedicated air supply for the stove or furnace. That way air for combustion is going straight into the firebox. The humidity level inside the house envelope does not drop with the outside temps.
In this way you are also not using air you have just heated to support combustion.
