A wood-burning heating apparatus, used as a parlor stove, and providing a significant heat output is disclosed. The stove has primary and secondary combustion chambers and a baffling arrangement for directing flue gases along a circuitous path to the exit aperture whereby a significant proportion of the heat of said gases is given up to the apparatus. A vertically oriented downwardly directed baffle separates the combustion chambers. Primary and secondary air paths supply air to the primary and secondary combustion chambers respectively. Each of the supply conduits is pre-heated and the secondary air supply provides oxygen substantially evenly around an opening at a bottom portion of the baffle to increase the efficiency of secondary combustion. The apparatus is further provided with a self-clearing top smoke chamber having a pivotable top cover. A rotatable flue collar is provided for either a horizontal or a vertical connection to the exit flue.
