A heater with a visual flame display is described. The heater may include a top portion and a base, separated by concentric cylinders. The innermost cylinder houses a flame element, which may be spun into a vortex. The cylinders may be constructed from transparent materials such that the flame element is visible to an observer. The base provides heat at or near ground level for efficient heat distribution.

A display generally comprising a container that contains a source of combustion and a heat exchange assembly positioned above the source of combustion is disclosed. The heat exchange assembly is heated by the source of combustion and air passing through the assembly is heated and directed to the surrounding area around the display.

Disclosed is a decorative gas stove. The decorative gas stove includes a stove body and a viewing platform. A cavity is defined in the stove body. An energy device is provided inside the cavity for storing gaseous fuel. A supply pipe is provided inside the cavity for transporting the gaseous fuel. A water tank is provided on an upper end of the stove body and a bottom of the water tank is defined with a plurality of air outlet holes communicated with the supply pipe. An ignition portion is provided on a side wall of the water tank for igniting the gaseous fuel flowing to a water surface through the air outlet holes when the water tank is stored with water.

A gas burner assembly for an appliance includes a circular inner wall that defines a plurality of inner flame ports. An elongated outer wall extends around the circular inner wall such that the elongated outer wall is spaced from the circular inner wall. The elongated outer wall defines a plurality of outer flame ports. A cap is positioned on the circular inner wall over the plurality of inner flame ports and on the elongated outer wall over the plurality of outer flame ports.

A heater with a visual flame display is described. The heater may include a top portion and a base, separated by concentric cylinders. The innermost cylinder houses a flame element, which may be spun into a vortex. The cylinders may be constructed from transparent materials such that the flame element is visible to an observer. The base provides heat at or near ground level for efficient heat distribution.

A fuel-burning cooking burner includes a base defining an outer periphery and an inner open area. The burner further includes a cap coupled with the base around the outer periphery thereof and extending over the open area to define a distribution cavity on an interior side of the cap. The cap further defines a convex outer surface extending opposite the distribution cavity and a plurality of outlets extending through the cap from the distribution cavity to the exterior surface. The outlets are distributed over the entire exterior surface.

A heater includes a lower supporting unit, an upper supporting unit and a burner. The upper supporting unit includes pillars and two end elements. Each of the end elements includes a disc connected to an end of each of the pillars, positioning recesses for receiving and hence positioning the ends of the pillars, and at least one aperture. The lower supporting unit is connected to the disc of one of the end elements. The burner is connected to the disc of the remaining end element and includes a fuel pipe extending throughout the apertures of the end elements.

A gas cooktop includes a gas burner and a grate for supporting cookware above the gas burner. The grate includes a removable insert having an upper surface and a lower surface and a plurality of tines for supporting the removable insert. When the lower surface of the removable insert is contacting the plurality of tines, the grate supports flat-bottomed cookware on the removable insert at a first height above the gas burner. When the upper surface of the removable insert is contacting the plurality of tines, the grate supports flat-bottomed cookware on the removable insert at a second height above the gas burner, the second height being greater than the first height. When the removable insert is not contacting with the plurality of tines, the grate supports round-bottomed cookware on the plurality of tines.

A heater is provided which has a heating chamber divided into a plurality of heating compartments, each operably to provide heat in a respective heating direction. The heater includes a respective heating element for each heating compartment, and the operation of at least one of the heating elements is independently controllable from the operation of at least one other heating element. There is also provided a gas burner assembly the heat and a control system controlling the operation of the heating element.

A gas burner having a switchable flame includes a combustion chamber having a bottom and a circumferential crenellated wall with a plurality of fuel exit ports disposed in the circumferential crenellated wall. The fuel exit ports are directed generally inwardly toward the combustion chamber and also upwardly from the bottom of the combustion chamber. The gas burner additionally includes a burner base and a swirl spreader disposed above the burner base which defines a top portion of the circumferential crenellated wall of the combustion chamber. An annular burner cap set includes an inner flame burner cap and a vertical flame burner cap where the inner flame burner cap and the vertical flame burner cap are selectively and alternatively positioned on the circumferential crenellated wall to define an inner flame state and a vertical flame state, respectively, of the fuel exit ports.
