We've been having some very cold weather in my area over the past few weeks, so I've been working my wood stove pretty hard. What I'm finding though is that the wood I'm burning is producing a huge quantity of coals and those coals are now taking up about half the space in the stove. I keep opening the door to stoke them and try to let them burn down, but then the house gets cold. I've tried to just let them burn down for a while with the door closed too, but still, the house gets cold when I'm not feeding the fire with new wood. As long as I see a flame in the stove, I feel good heat coming from it, but when the flame goes out and the wood turns to coals, no more good heat. I'm wondering what's going on. Why is my firewood producing so many coals and what can I do to reduce the amount? Has anyone else gone through this? It seems like it only happens when it's super cold outside. On warmer days, it's fine.
