We have an old Glenwood cabinet stove I got at a garage sale 24 years ago for $15.00. I burned wood in it the first couple years but with the price of wood and all the work, that ended. Just used it for power outages. This year I got a half ton of bagged nut coal to try. We have electric heat in our 1000 sq ft cape and the bill from mid Nov to mid Dec was $376. After that bill I got going and used the stove full time. Our mid Dec to mid Jan bill was $109. Mid Jan to mid Feb was $125. So half a ton of coal per month at $150 per half and being warm is working out for us. At first I had trouble keeping the fire going for more than three days but reading this forum I've finally got the hang of filling the box up to the bottom of the door and the fires being going for two weeks now. I know our stove is nothing fancy but it works great. I remember a few below zero nights I had to crack a couple windows because it was so warm in here. The dogs wouldn't even sleep in the livingroom,lol. BTW I use Blaschak coal and have no complaints about it.
Besides being an interesting read this forum has been a great help and I just wanted to say thanks.
