A gas cooker and a valve assembly for a gas cooker are provided. The gas cooker may include a case; a top plate that shields an upper surface of the case and on which items to be cooked are seated; a plurality of burners provided inside of the case; an electric valve assembly that controls a gas supply to the plurality of burners; a main pipe connected to the electric valve assembly and that supplies gas; and a plurality of branched pipes, respectively, connected to the electric valve assembly and the plurality of burners. The electric valve assembly may include a main valve connected to the main pipe; a plurality of sub-valves respectively connected to the plurality of branched pipes; and a manifold that connects the main valve and the plurality of sub-valves in parallel and enabling the main valve and the plurality of sub-valves to be consecutively provided and configured in a single assembly form.

In one aspect, an appliance for heating food, in particular a grill, and/or for emitting heat to the surroundings, in particular a heating appliance, includes at least one provision unit for providing hydrogen and at least one reaction unit for generating heat from the hydrogen. In one implementation, the reaction unit is designed as a catalytic unit for the flameless combustion of the hydrogen having at least one catalyst for catalyzing the hydrogen.

A temperature control appliance adapted for installation over an outdoor gathering area provides infrared, radiant heat or evaporative cooling modes. The radiant burner has a semi-cylindrical porous foam metal radiator element mounted in a housing to direct infrared heat to the gathering area. Evaporative cooling is provided by misting nozzles mounted on the burner housing.
