Just as the title says, can an Englander 28-2500 burn coal? I have an opportunity to get one and the person is claiming it will burn coal. There is also a metal grate in the firebox above the firebrick/vent base. Is this supposed to be there? I would love to run coal since it costs almost nothing where I am but from what I have read this is a wood only stove. Anyone ever run coal in this one?
