Fireplace and room heater

Patent ·
OSTI ID:6540922

A fireplace and room heater is disclosed that makes use of both natural air convection and forced air principles to efficiently heat an adjacent room. The fireplace and heater is freestanding and includes a firebox that is enclosed on three sides by a shell. The shell forms an air space between its walls and the firebox that is used for passage of air. A bulkhead separates the space into two distinct plenum chambers, an upper chamber and a lower chamber. A blower is provided at the rear of the unit. An intake of the blower opens into the lower plenum chamber. A discharge of the blower opens into the upper plenum chamber. Air is drawn through the lower plenum chamber by the blower and is forced outwardly through the upper plenum chamber through the blower discharge. The blower is controlled by a rheostat and thermostat to facilitate selective adjustment of air flow through the unit.
