I have been using a Johnsons stove I bought used for five years. I burn it 24-7 all winter. It is plumbed into my heater ducts. If it has a handle that goes onto a square nut in the fire door that shakes the grate it is setup to burn coal too. I burn about 5 cords of wood a year and two tons of soft coal a year with it even though I do not have the coal grate. It has been a great stove for me my dad has one of the smaller Johnsons and he has not had a problem either. Actually the only problem that I have had with it is if the power goes out it will smoke the paint off of it and stink up the house bad. When the power goes out I have to choke it down and pull the ducts off so the heat will come out of the jackets. It does use std fire brick if you need it I got mine from TSC. I leave one of the heat pipes cracked to put more heat into the basement.
