Abstract
A shroud is used to encompass a space heater ordinarily used within a tent or shelter. The shroud allows the space heater to be used outside the tent or shelter. The shroud is made from a series of components and is readily disassembled to allow compactness for storage or moving. The shroud is positioned over the space heater and ambient air is drawn into the spaces between the shroud and the heater where the air is heated by the heater. The heated air leaves the shroud through a duct when extends to the tent or shelter sought to be heated.
Claims19
A shroud for a space heater used for combusting fuel with the combustion products exiting the heater through a stack and combustion air entering the heater through a heater intake, a casing surrounding the heater which casing is heated by combustion within the heater and which casing radiates heat to the atmosphere, said shroud enclosing a significant portion of said space heater and allowing ambient air to circulate between said casing of said space heater and the inside of said shroud and to therefore become heated ambient air, an exit port formed in one end of said shroud to allow said heated ambient air to exit said shroud and to enter into a duct operable to extend to a tent or shelter and to discharge said heated ambient air into said tent or shelter, said shroud being removably positioned on said heater for facilitated installation or removal thereof, said shroud further having a door which may open or close to allow the commencement of combustion within said heater.
A method of heating a tent or shelter from a location outside said tent or shelter and using a space heater otherwise operable within said tent or shelter, said method comprising positioning said space heater outside said tent or shelter, positioning a removable shroud on said space heater such that said shroud substantially encloses said space heater and leaves air passageways between the outside of said space heater and the inside of said shroud, allowing said ambient outside air to enter said air passageway and to be heated by the outside of said space heater, directing said heated ambient air through a duct to said tent or shelter and releasing said heated ambient air into said tent or shelter.
