An apparatus for extracting heat from the waste gases of a stove to heat the air in the room. The apparatus is mounted on the stove and includes a central chamber in which an inner core, having a plurality of passageways, is positioned. Waste gases from the stove enter the central chamber, pass through the passageways of the inner core so as to heat the air surrounding the inner core, and then exit from the central chamber. A removably mounted closure is mounted on the top end of the central chamber to enable cleaning of the insides of the passageways. A heat shield which extends below the bottom end of the central chamber so as to surround the back and sides of the stove is provided to protect adjacent walls from the heat radiated by the stove.
