Abstract
Abstract A heater usable for indoor and outdoor use including a body having an upper and a lower portion. The two portions are separated by a grate adapted to support a solid fuel within the upper portion. The lower portion is operable to receive a receptacle for a lighted semi-solid fuel. The heater can be used in two modes, in a high heat output mode in which the solid fuel is first lit by the semi-solid fuel that is then removed or in a lower heat output mode in which the upper solid fuel is dispensed with and the heat is given off by the lower portion semi-solid fuel receptacle only. The upper portion of the heater is selectively closed or opened by a lid to allow heating operation or to provide damping operation when the lid is in its lowered position.
