A radiant area heater includes a columnar base with a hollow compartment and a heating column disposed on the columnar base. The heating column includes a control portion with at least one controller, a burner, and a sparker and a flame portion that includes a combustion chamber. The combustion chamber is disposed on a cylindrical member that has at least one vent allowing air to circulate to the burner and within the combustion chamber. The heating column further includes at least one heat emitting screen disposed above the flame portion that radiates heat outwards from the heater. A cover is disposed over the heating column to direct heat outwards and away from the heater.

The present invention comprises an assembly patio heater (PH) base at the bottom, a gas combination valve, a reducing bushing unit, a PH perforated cylinder, a tubing unit along with the pilot assembly, PH pan head, a gas combination control assembly, a gas lighter unit, a burner assembly and an assembly PH emitter grid assembly. A reflector is mounted at the top of the assembly PH emitter grid assembly. The present invention provides an automatic ignition system along with ON/OFF switch and the device also has an inbuilt transformer which provides the safety to the user(s). Hence, the present invention is very easy to operate and user friendly.

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.

An accessory for a patio heater includes a bracket to secure to a pole of the patio heater; two arms attached to and extending away from the bracket in an upward direction; and two concave shields attached to the arms to bend around a heating element of the patio heater; the concave shields reflect heat in a desired direction.

A Patio Heater Double Dome Infrared Heat Reflector/Converter is disclosed. The patio heater dome attachment is attachable to a conventional patio heater so that the dome attachment covers the heater's heat shield, while maintaining an air gap therebetween. There are preferably standoff ridges or other features built into the dome attachment to maintain this air gap and to prevent air from flowing freely between the heat shield and the dome attachment. The dome attachment embodies a very low heat load so that very little heat conduction occurs between the heat shield and the dome attachment, such that more of the heater's energy is reflected towards the usage area. Finally, the perimeter edge of the dome attachment extends downwardly at least until it is essentially horizontally planar with the perimeter edge of the patio heater heat shield.

The present invention provides a safer all-around radiation heating assembly than similar traditional heaters. As typical with traditional heaters, a shroud is used to surroundably cover a portable liquid propane tank. To replace the portable liquid propane tank, the shroud must be continuously raised to a predetermined height while a service person accesses the propane tank. There is a danger that if and when the shroud drops, a spark could be created resulting in igniting highly flammable escaped propane gas. The present invention overcomes dangers associated with the traditional heaters by eliminating the spark creation danger and by introducing a ventilation system to allow any leaked propane gas to escape away from the heater.
