Im glad you are seeing the benefits of coal and the drawback of pellets. The btu of coal vs pellet is much higher. You will like the Kodaik. A freind of mine has it and it is one great stove. Heats his entire house with it. A little over 2500 sqft. He uses anywhere from 3-4 tons. You can easily get 100k btus out of that stove. Something you cant do with any pellet stove. Best of all, no electricity! No augers, blowers etc. The round grate system seems to work really well too.
