I paid $350 for coal ... and cut my own firewood. My ceiling fan runs year round in two different modes.
How much coal do you normal use in a winter?
How many cords of wood per winter?
I use the coal stove primarily for back up for my wood stove ... or to supplement it through the very cold days of winter.
When the temps settle down into the single digets, the wood stove cannot keep it warm enough upstairs for comfort. Nothing will freeze up, but, unless I want to deal with 45 degrees in the main living areas and my third floor loft/bedroom/bath ... I have to burn coal to back up the wood burner.
The coal stove is in the main living room on the 2nd floor.
I have a Stoker Coal Burner. So I can fill the hopper and leave for 3 to 5 days, depending on the setting and the outside temps. The colder outside, the higher the setting and so the more coal I must use for the heat to keep up.
It will be cold inside, but will not be freezing.
I bought a ton of coal from Holden, in Ovid this year ... and still have 800 pounds left over. So far.
Wood takes me all summer to gather, zipped into 18" lengths, and split using a hand mall and wedges.
I started with 7 rows of split hardwood. Each row measured 6 feet high, 18 inches wide and 25 feet long.
As needed, I fill the wood room in the finished basement. This room has a concrete floor, concrete block walls, is unfinished and directly adjacent to the wood stove.
I built a trap door under my deck that leads directly into the wood room. Thereby keeping the debris from firewood inside the house restricted to that room, and around the wood stove.
It's a constant cleaning of both the stove to prevent chimney fires and to keep up with the wood debris.
The dust from both the coal and the wood is killer. It's a filthy way to heat ... but saves me thousands on oil or gas heat.
I would guesstimate I use ten to 15 full cord a year. A cord is what? 4' wide X 4' high X 8' long? So that sounds about right.
I start stacking wood in the late spring and do wood all summer long; as soil conditions allow me into my woods to retrieve downed trees.
I have yet to had have to cut down a live tree for firewood.
With about 30 acres of wood lot, enough dies off, or is downed by storms, that there is always an abundance of hard wood like black cherry, oak, silver maple and, mostly, ash either standing dead or downed to be harvested to burn.
But living alone, it's a lot of work ... worth it for the savings but you cannot NOT get up and toss a couple logs on the fire if you expect to make it through the winter without the pipes freezing up. I have lived here for ten winters now and have yet to freeze my plumbing.
I have, however, had to deal with several chimney fires over the years. I put them out by firing 200 grains of black powder in my .50 caliber TC Fire muzzle loader UP the chimney through the plug in the bottom under the main deck.
It not only puts the fire out instantly, it cleans ALL the creosote out from top to bottom.
Since the wood stove is in the basement, and the chimney is 25 feet of triple wall that runs up through the roof, I repeat the procedure two or three times a winter to keep the chimney clean while burning.
( I let the wood stove go out for maitanance - unless there's fire at the top of the chimney ... and then it's "git r done" time.)
Short answer ... I use about a ton of coal and 12 to 15 full cord of mixed hardwoods from early September to mid-May each year.
