I have a newmac forced air furnace. when we get down below 10 degrees or so, i cant keep up. the temp in the house starts falling, but if i go to add wood there are so many coals, and they will melt your face off. but that heat doesnt seen to be transfering to the main trunk on top of the furnace. it gets to the point where i have to shovel the coals out by the bucketful to get enough wood in for a somewhat decent overnight burn (4 hours max below zero temps)
why am i not getting heat transfer from the coals?
