Just want to update. I only burned the coal for 1 week and went through 750 lbs. The temps were only cold for the first 4 days and it was pretty warm the last few days...warm enough the fire eventually went out due to not loading it up full. I feel that is a LOT of coal to use in a week especially when it wasn't as cold as it had been a good portion of the winter. At that rate I feel I would use well over 6 tons and it just isn't economically feasible for next year. That would cost me over $1500 unless I wanted to make a couple trips into PA to haul my own. We will eventually switch to a stoker as I like the coal heat but don't like the extra mess involved with shaking this thing 2 times a day. I am also very concerned with the grates themselves as they have been replaced and this is the 3rd new set. Luckily the first replacement set was warrantied. These are a very weak design. I placed my order for a load of logs to be delivered soon and will get it cut, split and stacked asap. It will be a lot more labor intensive. There is also another reason for the decision...I won't have to put anything on the credit card this way.
I will be looking at getting better air flow through the furnace to make it more efficient. There are lots of great tips and ideas on this so that will help. I will post updated pics as I progress over the summer and into fall when we start burning wood again. Thanks for all the help and awesome tips!
