Carbon Neutral – Renewable. A Woodburning Stove is a heating appliance capable of burning wood fuel and wood-derived biomass fuel, such as sawdust bricks. Generally the appliance consists of a solid metal closed firebox, often lined by fire brick. The first wood burning stove was patented in Strasbourg in 1557, two centuries before the Industrial Revolution. Such stoves were high end consumer items and only gradually spread in use.

The stove is connected by ventilating stove pipe to a suitable flue. This will fill with hot combustion gases once the fuel is ignited. The chimney or flue gases must be hotter than the outside temperature. This is  to ensure combustion gases are drawn out of the fire chamber and up the chimney.

The environmental impact of using wood as a fuel depends on how it is burnt. … Some may regard the burning of wood from a sustainable source as carbonneutral. A tree, over the course of its lifetime, absorbs as much carbon (or carbondioxide) as it releases when burnt.
