The disclosure relates to a wood-burning appliance. The wood-burning appliance comprises a firebox and an airflow apparatus configured to provide a supply of oxygen for efficient primary and secondary fuel combustion within the firebox. An oven may be positioned above the firebox to improve heat exchange from exhaust exiting the wood-burning appliance. The wood-burning appliance may further have a pulley system for operation of a door that reduces gasket wear and allows the door to be at least partially removed from the wood-burning appliance for ease of access and maintenance.

A solid fuel heating apparatus (1) comprising a combustion chamber provided with a glass door (4) opening to the outside, an intake device (11) for the intake of outside combustion air into said chamber, an outlet duct for the burnt gases (2) and a sealed preheating enclosure for preheating the combustion air, conveying said air to the combustion chamber, connected at a first end to the intake device (11) and ending at a second end with a plurality of openings (9) releasing the air preheated by the preheating enclosure into the combustion chamber, characterized in that the preheating enclosure consists of a set of sealed heat exchanging pipes containing the combustion gases and the burnt gases (3, 8, 12, 15, 17, 18, 19), ending with the abovementioned openings (9), which are variable in size and are arranged in such a way as to modulate the flow of preheated air released into the chamber, enclosing the flame and combustion area in the natural conical shape of said chamber.

A fire place enhancer is provided for combusting fuel and for placement into a fireplace within a wall of a room, wherein the fireplace has a chimney. The fire place enhancer includes: a main air shield having a main exhaust port, a main access port an air ingestion port and an air supply port; an inner surface disposed with the main air shield so as to provide a combustion area for combusting the fuel, the inner surface having a rear surface and two side surfaces; and a heat manifold disposed above the combustion area, the heat manifold having a first end and a second end, the heat manifold being operable to pass gasses from the combustion area to the chimney.

A fireplace system can comprise a firebox and a heat exchanger. The heat exchanger may be in fluid communication with ambient air and may comprise an inlet configured to draw air into the front of the heat exchanger. Operation of a fireplace system comprising a heat exchanger may produce airflow through the heat exchanger by natural convection. The airflow through the heat exchanger may reduce heat transmission from the firebox and the fireplace system.
