A radiant heating assembly including a burner for heating a heat exchanger and a reflector generally disposed about the heat exchanger. The reflector comprising a base defining a first air chamber. The reflector may also comprise one or more wings removably coupled to the base. The wings may be configured to define a second air chamber. The radiant heating assembly may also comprise an air circulation pump configured to draw air through the air chamber of the base and/or wing and provide the air to the burner to improve the efficiency of the combustion process.

A heater includes: a body that includes a furnace body and a mesh cover assembly; a burner assembly that is installed on the body; a gas tank that is arranged in the body and directly below the burner assembly; and a reflecting plate that is installed in the body and located between the burner assembly and the gas tank. The gas tank has an interface end connected to a fuel inlet end of the burner assembly via a valve. The mesh cover assembly and the burner assembly are detachably connected to the furnace body.

An infrared radiation heater includes: a combustion chamber having a combustion space that is open on one side; a combustion device provided in the combustion chamber to combust air-fuel mixture made by mixing fuel with air; and a radiator configured to be heated by heat generated from the combustion device and including a radiation plane configured to emit infrared radiation. The combustion device includes: a nozzle provided in a flow path of the air to inject the fuel; a tubular body including a side surface that faces a direction with a predetermined angle with respect to the radiation plane, and a plurality of voids being formed on the side surface; and an ignition device provided outside of the tubular body and configured to ignite the air-fuel mixture. The air-fuel mixture flows into the tubular body, and the tubular body releases the air-fuel mixture from the voids into the combustion chamber.

Systems and methods for radiative heat transfer are disclosed. In an exemplary embodiment, an infrared heater comprises infrared heating elements and a controller. The infrared heating elements correspond to respective heating zones. The controller causes the infrared heating elements to turn on at different time in succession such that respective heating zones are radiatively heated at different times. In some instances, the respective heating zones correspond to different heating zones of a user, and the user feels a heating wave effect as the infrared heating elements are turned on and off at different times.

A heater includes a body, a burner assembly, a gas tank, and a reflecting plate. The burner assembly is installed on the body. The gas tank is arranged in the body and directly below the burner assembly, and has an interface end connected to a fuel inlet end of the burner assembly via a valve. The reflecting plate is installed in the body and located between the burner assembly and the gas tank. The reflecting plate prevents heat coming from a bottom portion of a burner of the burner assembly from being radiated directly to the interface end of the gas tank and allows heat coming from around the burner to be radiated to a periphery of the interface end of the gas tank and heat the gas tank.

A radiant heating assembly including a burner for heating a heat exchanger and a reflector generally disposed about the heat exchanger. The reflector comprising a base defining a first air chamber. The reflector may also comprise one or more wings removably coupled to the base. The wings may be configured to define a second air chamber. The radiant heating assembly may also comprise an air circulation pump configured to draw air through the air chamber of the base and/or wing and provide the air to the burner to improve the efficiency of the combustion process.

A plaque for a radiant heating system can include a main body defining an outer surface and a plurality of pores defined within the main body, wherein at least some of the plurality of pores are disposed in a non-parallel relationship with at least some others of the plurality of pores, or wherein at least some of the pores are parallel with each other. A burner assembly including a plurality of adjacently arranged plaques reduces the ignition time and delay for adjacent plaques after the central plaque has been ignited.

A kiln includes a stove, a combustion device, and an exhaust pipe, wherein the stove includes a cavity, an entry, and an air outlet. The cavity includes a front section and a rear section, and a top wall surface of the front section is tilt. The air outlet is disposed between a top of the front section of the cavity and the entry. The combustion device is disposed in the rear section. The combustion device includes at least one burner, a supporting assembly, and an infrared ray generation assembly. The supporting assembly includes a cover plate having a hollow portion. The infrared ray generation assembly is mounted to the supporting assembly and located above the cover plate. The infrared ray generation assembly could be heated by the flames of the burner to generate infrared ray which passes through the hollow portion. The exhaust pipe communicates with the air outlet.

A portable heater includes a housing enclosing a combustion region, a first connector for connecting with a fuel source, a first supply line in fluid connection with the first connector for supplying fuel to the combustion region when the fuel source is connected with the first connector, a second supply line in fluid connection with a second connector for supplying fuel to a fuel-fired accessory when the fuel source is connected with the first connector and the fuel-fired accessory is connected with the second connector, and a valve arrangement operable to selectively supply fuel to the first and second supply lines when the fuel source is connected with the first connector.

An outdoor, free standing area heater comprises a vertically extending housing defining an interior and a heat producing source for producing a flame that heats air and at least one glass tube directing at least a portion of the heated air upwardly inside the housing. An upper hood is located above the housing at a position for the heated air conducted by the at least one glass tube to impinge on the upper hood, the upper hood being shaped to redirect the heated air in a direction away from the housing and in a general downward direction from the upper hood. The glass tube is substantially surrounded by side panels that are provided with a plurality of cutouts in a wall defining each of said side panels, wherein the cutouts leave a percentage closure of the wall in the range from 1 to 65 percent.
