A convection outdoor or indoor gas heater is provided, the heater comprising: a top; a first wall; a combustion chamber which includes a vent cap with a plurality of vents, the vent cap proximate to the top, the combustion chamber housed within the first wall, spaced apart from the first wall to define a first interstitial passageway, the first interstitial passageway in fluid communication with the plurality of vents; a gas burner assembly which is housed in the combustion chamber; a second wall spaced apart from the first wall to define a second interstitial passageway, the second interstitial passageway in fluid communication with the first interstitial passageway; a base which supports the first wall, the second wall and the combustion chamber; a combustion air inlet in fluid communication with the combustion chamber; an ambient air inlet in fluid communication with the second interstitial passageway; and an outlet in fluid communication with the first interstitial passageway.

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.

According to one embodiment, a rack includes a pair of spaced apart inverted U shaped brackets. Each bracket has a top portion coupled in-between a rear leg and a front leg and forming a gap in-between the rear leg and the front leg. The top portion, the rear leg, and front leg of each bracket are disposed in a first plane. The rack further includes one or more horizontal coupling members coupled in-between the pair of brackets. The horizontal coupling members and the front leg of each bracket are disposed in a second plane that is orthogonal to the first plane. The rack also includes one or more first horizontal supporting members coupled to and extending outward from a first bracket of the pair of brackets. The first horizontal supporting members are disposed in a third plane that is orthogonal to the first and second planes.
