A fireplace stove that is quickly and easily installed in a conventional fireplace with little or no modification of the fireplace or chimney comprises a firebox that is shaped and dimensioned to be at least partly received in a fireplace but with clearance between it and at least some of the walls of the fireplace to facilitate heat transfer by convection. A flue leading from the top of the firebox extends a short distance up into the chimney flue. Oxygen to support combustion in the firebox is supplied by a duct that leads from the chimney flue into the firebox, the inlet opening to the duct being located some distance below the outlet from the stove flue. The space between the stove flue and duct and the chimney flue is closed off so that there is no communication between the fireplace, and thus the living space, and the chimney flue, thereby eliminating loss of heat from the living space by natural draft up the chimney flue and providing for delivery of heat by radiation, convection and conduction from the stove to the room efficiently.
