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.
