Patent ID: 8893706

Claim:
A heating device comprising: a housing assembly having a combustion region disposed therein; a support attached to the housing assembly, the support having an interior chamber adjacent to the combustion region; a motor operatively connected to a fan blade, wherein operation of the motor causes the rotation of the fan blade to draw ambient air through an air intake end of the housing assembly and at least a portion of the ambient air is directed into the combustion region; a fuel assembly comprising: a fuel tank suitable for containing a liquid fuel; a burner assembly, wherein the burner assembly is in fluid communication with the fuel tank and allows the liquid fuel to be communicated from the fuel tank and mixed with air to form an air/fuel mixture and the air/fuel mixture is communicated through the burner assembly and into the combustion region; an ignition system, wherein operation of the ignition system causes the combustion of the air/fuel mixture within the combustion chamber resulting in a heated air and the rotation of the fan blade to direct at least a portion of the ambient air into the combustion region results in the heated air being expelled out of a discharge end of the housing assembly; a control assembly comprising: a control unit for controlling the operation of the heating device; and, a power supply, wherein the power supply comprises: a first power source in electrical communication with the control unit, wherein the control unit controls the operation of the first power source to selectively supply electrical power to at least a portion of the heating device, wherein the first power source comprises a selectively removable rechargeable battery; a second power source in electrical communication with the control unit, wherein the control unit controls the operation of the second power source to selectively supply electrical power to at least a portion of the heating device; a recharging unit, wherein the rechargeable battery can be selectively placed in electrical communication with the recharging unit to cause the recharging of the rechargeable battery; wherein the control unit and the first power supply are located within the interior chamber adjacent to the combustion region.
