Abstract
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.
Claims19
A radiant area heater comprising:
- a columnar base that includes a hollow compartment;
- a heating column disposed on the columnar base, the heating column comprising:
- a control portion that comprises at least one controller, a burner, and a sparker;
- a flame portion that comprises a combustion chamber, the combustion chamber being disposed on a cylindrical member, the cylindrical member comprising at least one vent allowing air to circulate to the burner and within the combustion chamber;
- and
- an upper heat emitting screen and a lower heat emitting screen disposed above the flame portion, the upper heat emitting screen and the lower heat emitting screen radiating heat outwards from the heater, the upper heat emitting screen having a width that is greater than a width of the lower heat emitting screen;
- a wire cage disposed to surround the combustion chamber, the upper heat emitting screen and the lower heat emitting screen;
- and
- a cover disposed over the heating column, the cover being configured to direct heat outwards and away from the heater.
A radiant area heater comprising:
- a cylindrical columnar base, the columnar base comprising:
- a base flange at a bottom of the columnar base, the base flange comprising at least one wheel;
- and
- a hollow compartment configured to house a fuel tank therein;
- a middle flange disposed above the columnar base;
- a cylindrical control portion, the control portion comprising at least one controller, a burner, and a sparker;
- a cylindrical flame portion disposed above the middle flange, the flame portion comprising:
- a transparent cylindrical combustion chamber disposed above said burner;
- a cylindrical supporting member configured to hold the combustion chamber, the supporting member comprising at least one vent allowing air to circulate to the burner and within the combustion chamber;
- an upper heat emitting screen and a lower heat emitting screen disposed above of the combustion chamber, the upper heat emitting screen having a diameter that is greater than a diameter of the lower heat emitting screen;
- a wire cage disposed to surround the combustion chamber and the upper heat emitting screen and the lower heat emitting screen;
- and
- a cover disposed above the upper heat emitting screen and the lower heat emitting screen, the cover configured to direct heat outward from the heater.
A heater comprising:
- a base configured to support the heater;
- a burner located in or above the base, the burner in gaseous communication with a source of combustible gas;
- a combustion area extending upward from the base and located above the burner, the combustion area having cross sectional area of greater than 706 square centimeters;
- air vents adjacent or below the combustion area, the air vents having an area greater than an area of the burner to allow air flow into the combustion area to complete combustion of the combustible gas;
- an upper heat emitting screen and a lower heat emitting screen disposed above the combustion area, the upper heat emitting screen having a width that is greater than a width of the lower heat emitting screen;
- and
- a top cover above the combustion area configured radiate heat downward and outward;
- further comprising a wire cage disposed to surround the combustion area, the upper heat emitting screen, and the lower heat emitting screen.
