Hi Bill!
Well, I never had theese problems. I use to keep my wood, cut in 1 metre bulks out in the woods for about 1,5 year. Later on I bring them home and cut them to 0,25 - 0,40 metre. Then I store them in a pretty dry place with where they can exhaust.
I don´t use a "Chimney-ofen" I use a "Sweden-ofen". The wood is cast in the ofen itself and the heat goes out through the fire-safe-glass and the steel around the ofen. Just right now, the ofen is heated. It´s got about 28° Celsius inside my house and outside there are about - 18 ° Celsius. So pretty cold.
I always use to fire Pine, Bir, Spruce and other "needle-woods" as it´s translated word-by-word from german to english. It gives a good heat and can be taken out in the woods. You and me seem to work on the same base. Just the ofen is another one. Cutting darr trees or getting the rest of what the Harvester left behind is good enough to me for a warm home. I takes a lot of work, but I like that work. It´s best and most healthy thing anyone can do.
About the fire-danger, I don´t have the problem because of the glass which keeps the flames inside the ofen.
Kind regards
Andi
