Abstract
A wood burner includes a wrapper. A firebox is positioned in the wrapper that defines a combustion chamber. An air inlet is placed in communication with an external air supply. The air inlet includes a conduit to conduct the external air to the combustion chamber and a second conduit. A manifold is positioned above the firebox. The manifold is in communication with the second conduit, and includes one or more manifold chambers for permitting the external air received thereby to become heated. A plurality of air tubes connect to the manifold to receive the heated external air from the manifold, each plurality of air tubes including a plurality of apertures to direct the heated external air into the combustion chamber adjacent an upper inner surface of the firebox.
