Description

ABSTRACT:
A wood burning stove for providing heated air to a room or similar area includes a fire chamber, a hearth in the forward portion of the fire chamber, draft inlet means at the front of the fire chamber and a flue at the rear of the fire chamber. Between the hearth and the flue is an enclosed air chamber having front and rear walls; the air chamber communicates at its bottom with the ambient air and at its top with one or more air pipes which extend to the front of the stove and there open to the ambient air. A baffle plate is positioned between and spaced from the air chamber and the flue. Ambient air is heated by passing it through the air chamber and air pipes after they have been heated by hot gases rising from a fire burning on the hearth; the hot gases contact the air pipes and the front wall of the air chamber and, because their normal path of travel to the flue is altered by the baffle plate, contact the rear wall of the air chamber as well.
