An airtight wood burning stove is a heating appliance capable of burning wood fuel and wood derived biomass. Generally the stove consists of solid metal, either cast iron or steel, a closed firebox lined by bricks with an air diffuser and a damper.

Although wood burning fireplaces do not offer significant heat output for the entire home, they are designed to provide the nostalgia, comfort and ambience of a traditional fireplace.

Catalytic wood burning inserts are designed to fit into an existing fireplace and chimney. In a catalytic wood burning insert, the combustion gases are passed through a catalytic converter inside the unit where they are burned thus reducing harmful emissions. They are engineered to produce the longest & most even heat output.
