Trying to figure this thing out. Do you guys load your furnace when the wood is burnt down or when your house starts losing heat? I was loading a wheel barrow in my owf every 10-12 hours, I would have little wood left but a large amount of coals. Like a good 8-10 inches of coals. This is with outdoor temps of 15-25. Recently I have been playing with it a little, and found my house will stay warm (70-72) for 18-20 hours even though the water temp in the owf is down to 100-110. It just takes a long time for it to reach 180 when I do load it.
