No, the heat production on any coal stove is controlled by the amount of air being drawn from under the fire. You control that air by the vent on the lower front of the stove. The size of the coal only plays to the ease and length of burn. The larger the coal, the bigger the space between the pieces of coal for air to flow, more air passing through the coal, the faster the burn. If you want a long burning coal fire go with a smaller size of coal because the coal bed is tighter with less air moving through it. If you want that fire hotter open the air vent. Any sized coal will burn, the question is what size will give you the most heat at the level of effort you desire, i.e. how often do you want to tend the fire? I'm with Fred, start with nut.
How do the grates shake? Most of the "laundry stoves" I've seen have a special tool you insert above the front air vent that you slide left and right to shake the grates but there could be a handle somewhere else on the stove.

You are right, this little stove should have no problem heating your hunting shack. I bet you could even cook a decent meal on it. It was designed to hot water fast. Good luck, Lisa
