An oven appliance includes a cabinet with a chamber is defined within the cabinet for receipt of food items for cooking. The oven appliance also includes a gas burner positioned proximate to a bottom portion and/or a back wall of the chamber. A natural convection flow path is defined through the chamber. The natural convection flow path extends from an origin at the gas burner to a top wall of the chamber. The oven appliance further includes a convection fan positioned along the natural convection flow path above the gas burner and below the top wall. The convection fan is positioned and configured to divert combustion products generated by the gas burner from the natural convection flow path along a forced convection flow path towards a center of the chamber when the convection fan is activated.

An oven appliance includes a cabinet defining a vertical direction, a lateral direction, and a transverse direction. The vertical, lateral, and transverse directions are mutually perpendicular. The cabinet comprising a front portion spaced apart from a back portion along the transverse direction and a left side spaced apart from a right side along the lateral direction. The oven appliance also includes a chamber defined within the cabinet for receipt of food items for cooking. A broil heating element is positioned proximate to a bottom portion of the chamber.

The present disclosure is directed to a multi-heat source apparatus. The multi heat source may include a fire pit and is configured to provide ambient heating with both convection heat transfer and radiation heat transfer. The multi-heat source apparatus comprises an infrared emitter for generating infrared radiation. The multi-heat source apparatus comprises a shielding member between a heat source for the convection heat transfer and another heat source for radiation heat transfer.

An oven appliance may include a cabinet, a plurality of chamber walls, a cooking surface, a top heating element, a temperature sensor, and a controller. The cooking surface may be defined in a cooking chamber. The top heating element may be mounted above the cooking surface to heat the cooking chamber. The temperature sensor may be disposed within the cabinet. The controller may be configured to initiate a cooking operation that includes initiating preheat activation of the top heating element, receiving temperature signals from the temperature sensor during the preheat activation, determining a preheat threshold is met based on the received temperature signals, and initiating cooking activation of the top heating element based on a cooking cycle having a predetermined time interval subsequent to determining the preheat threshold is met. Initiating cooking activation may include directing the top heating element based on the cooking cycle for the predetermined time interval.

Systems and methods of a pellet-fired heating include a system having a combustion chamber in which combustion gas is generated from fuel pellets. The combustion chamber includes a fuel inlet for receiving fuel pellets into the combustion chamber, an air inlet for receiving air into the combustion chamber, and a combustion gas outlet for discharging combustion gas from the combustion chamber. The system further includes a first radiator extending into a space to be heated having an internal passage in fluid communication with the combustion chamber, via the combustion gas outlet, and one or more discharge outlets for discharging the combustion gas from the internal passage into the space. A blower of the system is configured to push air into the combustion chamber via the air inlet and push the combustion gas from the combustion chamber into the internal passage of the first radiator.
