A patio heater, has: a base to be supported on a ground; a stem protruding upwardly away from the base; and a heat generating device secured to the stem, the heat generating device having: a burner fluidly connected to a source of a fuel to be burned; a diffusion sheet enclosing a combustion chamber, the burner located inside the combustion chamber and surrounded by the diffusion sheet; a reflective shield located above the diffusion sheet; and at least one reflective fin mounted to the diffusion sheet and extending away therefrom.

A portable heater shield assembly for directing heat laterally away from a heat source includes a plurality of panels that removably engaging each other to form a disk. Each of the panels is comprised of a heat resistant material. A plurality of brackets is each removably coupled to a heat source having the brackets being vertically oriented. The disk is positionable on top of the brackets when the brackets are removably coupled to the heat source having the disk spaced upwardly from the heat source. In this way the disk directs heat laterally away from the heat source for warming users sitting around the heat source.

A heating device includes a base member and a gas burner mounted in or on the base member. An upper housing located above the base member and a tabletop mounted above the upper housing. A hollow heat shield having a proximal end located on or near the base member, and a distal end located within the upper housing, and a support member extending between the base member and the upper housing or tabletop. The distal end of the heat shield extends beyond a proximal end of the upper housing, defining a region of vertical overlap between the heat shield and the upper housing.

A cooking appliance, as provided herein, may include a cabinet, a plurality of electric heating elements, a heat shield, and a vapor catalyst. The cabinet may define a cooking chamber and an exhaust path downstream therefrom to direct vapor from the cabinet through an exhaust outlet. The plurality of electric heating elements may be mounted within the cabinet. The heat shield may be mounted within the cabinet. The heat shield may extend along a shield plane from a first end to a second end. The vapor catalyst may be mounted within the exhaust path above the heat shield and rearward from the exhaust outlet to receive and clean vapor from the cooking chamber upstream from the exhaust outlet.

The invention relates to an electrical heating apparatus for arranging under a table, the heating apparatus comprising a housing, at least one electrically powered heat source arranged inside said housing, and heat shielding means comprised in the housing and having a plurality of through holes configured for allowing heat radiation from the electrically powered heat source to pass, wherein the heat shielding means comprises a layer of a material with a thermal conductivity lower than 2 [W.Math.m.sup.1.Math.K.sup.1], and wherein the inner surface of the heat shielding means is applied with a layer of heat radiation reflecting material configured for reflecting the heat radiated from the heat source back against the inner part of the housing.

A base supports a fire platform with a burner. A tabletop defines an opening with a contour matching a contour of a top rim of the fire platform and is selectively fitted to the base to create a table surface around the fire platform. A fire column selectively fits to the fire platform such that flame from the burner travels into the fire column.
