A vertically storable combustion heater having a fuel tank having a generally-cylindrical passage formed in the fuel-tank housing through which an axle extends to support one or more wheels; a heating conduit that is coupled to the fuel tank and includes an outermost shell that is substantially concentric with an inner shell that has a smaller diameter than the outermost shell; a control panel that is connected to the combustion heater to interface with an operator and allows the operator to input instructions governing the operation of the combustion heater; a frame that at least partially encases the heating conduit and fuel tank; a hose having a return curve and nozzle; and a combustion chamber that is defined by the interior periphery of the inner shell.

What is claimed is: 1. A vertically storable combustion heater, said heater comprising: a tank adapted to contain fuel, said tank fluidly engaged with a fuel conduit at a connection point, said fuel tank adapted to siphon fuel from said fuel conduit when said heater is transitioned from a first orientation for operation, to a second orientation for storage, wherein said first orientation is horizontal and said second orientation is vertical; a heating conduit that is coupled to the fuel tank and includes an outermost shell that is substantially concentric with an inner shell that has a smaller diameter than the outermost shell; a control panel that is connected to the combustion heater to interface with an operator and allows the operator to input instructions governing the operation of the combustion heater; a frame that at least partially encases the heating conduit and fuel tank, the frame extending beyond opposite ends of the tank and the heating conduit such that the combustion heater rests on an end of the frame in the second orientation; and a combustion chamber that is defined by the interior periphery of the inner shell wherein in said second orientation, said fuel conduit comprises an upright U-shaped section forming a return curve wherein liquid fuel can pool when the combustion chamber is in the second orientation. 2. The vertically storable combustion heater of claim 1, further comprising one or more wheels each positioned within a wheel well that is formed in the fuel tank and recessed inwardly toward the center of the fuel tank, said one or more wheels each having an internal side oriented substantially toward the heater and an external side oriented substantially away from the heater. 3. The vertically storable combustion heater of claim 1, wherein the control panel has a lock, on/off switch, ignition switch, a temperature controller, and a fuel controller. 4. The vertically storable combustion heater of claim 1, wherein the fuel-tank is molded as a single piece entirely from plastic. 5. The vertically storable combustion heater of claim 4, wherein the plastic is high-density polyethylene. 6. The vertically storable combustion heater of claim 1, wherein the inner shell is spaced radially inward of the outer shell to provide thermal insulation therebetween. 7. The vertically storable combustion heater of claim 1, wherein the frame includes a proximate end and a distal end separated by longitudinally extending members. 8. The vertically storable combustion heater of claim 7, wherein the frame further comprises a cross member serving as a handle at the proximate end that allows an operator to grasp the combustion heater and maneuver it as desired. 9. The vertically storable combustion heater of claim 7, further comprising a member that extends longitudinally along each side of the combustion heater externally of the one or more wheels, and adjacent to the external side of the one or more wheels, the member protecting the one or more wheels from impacting nearby objects while the combustion heater is being maneuvered. 10. The vertically storable combustion heater of claim 7, wherein the distal end has a suitably-wide footprint that can maintain the combustion heater in a substantially vertical orientation. 11. The vertically storable combustion heater of claim 1, wherein the combustion heater can be transported in a somewhat vertical orientation without leaking any fuel from the fuel tank. 12. The vertically storable combustion heater of claim 1, wherein the combustion heater further comprises a rain shield positioned adjacent to and offset from, an air intake of the heating conduit, said rain shield adapted to prevent the penetration of rain therethrough, and to interfere with the entry of falling objects or other debris into the heating conduit. 13. The vertically storable combustion heater of claim 12, wherein the rain shield is a substantially flat planar sheet of metal or other rigid material. 14. The vertically storable combustion heater of claim 1, further comprising a fuel outlet that is adjacent to the lowermost portion of the fuel tank while the combustion heater is in orientation for operation. 15. The vertically storable combustion heater of claim 14, comprising a hose or other fluid conduit adapted to provide fluid communication between the fuel outlet and a nozzle adapted to convey fuel into the combustion chamber. 16. The vertically storable combustion heater of claim 1, further comprising a fuel inlet through which fuel can be inserted into the fuel tank and also limits the amount of fuel that can be placed in the fuel tank. 17. A vertically storable combustion heater, said heater comprising: a fuel tank adapted to contain a liquid fuel, said fuel tank fluidly engaged with a fuel conduit at a connection point, said fuel tank molded as a single piece; wherein said heater is transitionable from a first orientation for operation, to a second orientation for storage said first orientation being horizontal and said second orientation being vertical; said heater further comprising, an adaptation to siphon liquid fuel from the fuel conduit when the heater is transitioned from said first orientation for operation to said second orientation for storage; a heating conduit that is coupled to the fuel tank and comprises an outermost shell, and an inner shell substantially concentric with said outer shell, said inner shell being of smaller diameter than the outermost shell, and spaced radially inward of the outer shell to provide thermal insulation therebetween; a hose or other fluid conduit comprising an upright U-shaped return curve adapted to function as a region wherein liquid fuel can pool when the combustion heater is in the second orientation for storage; a control panel that is connected to the combustion heater to interface with an operator and allows the operator to input instructions governing the operation of the combustion heater; a frame that at least partially encases the heating conduit and fuel tank, the frame comprising, a proximate end and a distal end separated by longitudinally extending members, said distal end comprising members between the longitudinally extending members suitably-wide footprint to maintain the combustion heater in a substantially vertical orientation, and a cross member serving as a handle at the proximate end that allows an operator to grasp the combustion heater and maneuver it as desired; a combustion chamber that is defined by the interior periphery of the inner shell; a plurality of wheels; a fuel outlet adjacent to the lowermost portion of the fuel tank when the combustion heater is in orientation for operation; and a fluid conduit adapted to provide fluid communication between the fuel outlet and a nozzle adapted to convey fuel into the combustion chamber.
