Abstract:
A method and apparatus for a self-contained heating vessel having enhanced efficiency and safety features. In one embodiment, the vessel includes a chamber for containing fuel; a burner assembly for burning the fuel; a fuel delivery mechanism that delivers the fuel from the chamber to the burner assembly; and a container disposed adjacent to the heat exchanger assembly, the container including an opening to an interior portion of the container. In other aspects, the vessel includes an ignition assembly operatively connected to said burner assembly and a heat exchanger assembly disposed adjacent to the burner assembly. In further aspects, the vessel includes a displacement sensor to prevent operation when displaced from an intended operating position and a pressure regulator that controls delivery of fuel to the burner assembly to maintain a substantially constant heating profile over a varying temperature range.
