I have a modern woodburning stove, where all the joints are double welded, and a double-glazed door. It does not have bricks, but the firebox is
lined with man-made fireproof panels. The stove itself can burn wood or coal, but the steel chimney cannot take the heat of coal. The chimney is dual walled steel, filled with insulation. It goes up through my bedroom, and the outer shell is just about touchable. In the UK, stoves and chimneys must be installed by HETAS approved installers. You can't do it yourself, although people do, and they also die of carbon-monoxide poisoning. The chimney has to work, and needs to be long enough to work. Installation is heavily regulated.
