Patent ID: 7823579

Claim:
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.
