Abstract: A heating panel system comprises a cylindrical hot water pipe. The pipe is in a linear configuration. A plurality of rigid fins is provided. The fins have apertures. The apertures allow the fins to be positioned over the pipe. In this manner inlet openings are formed. The inlet openings are of an enlarged size beneath the pipe and outlet openings. The pipe and outlet openings are of a reduced size above the pipes. In this manner the flow of heated air between the fins and across the pipe is increased due to venturi configuration of the design.

Abstract: The heat recovery reflector has a channel-like extrusion comprising a web and flanges bordering the web. The web has a heat reflective surface thereon and the flanges have a substantial depth relative to the thickness of the web. The distances between the flanges is similar to the height of the back surface of a baseboard heat convector. The channel-like extrusion is mountable behind a baseboard heat convector for defining with the back surface of the baseboard heat convector a closed space for maintaining the heat reflective surface in a dust free environment. In another aspect of the invention, each flange has serrations of the inside surface thereof. A pair of caps is provided for covering the ends of the channel-like extrusion. Each cap has tabs extending therefrom and each of the tabs has at least one notch which is engagedly mountable in one of the serrations on the flanges.

Abstract: An extreme infra-red rays air conditioning apparatus have a rear face plate installed on the rear face of the apparatus, a casing of square-box shape having an opening at its front face, heat radiation glass plate each made of heat-resisting reinforced glass having a plurality of small dents continuously formed or its whole face and a flat rear face. The size of glass plate is smaller than the opening of the casing and fixed to both side portions at the front face side by means of side portions of the glass plate. The air conditioning apparatus further has a number of linear shape heat generator made by melting metal alloy powder consisting of aluminum, copper, iron and the like on the flat rear face of the heat radiation glass plate in shape of printed circuit, reflex plate respectively fixed to the casing leaving gap at rear face sides of the glass plate, and extension members opening outwardly and expanded and extended to the front side end edge portions of the casing leaving distribution openings.

Abstract: An electric baseboard heater includes a ceramic glass block within which a steel wire electric heating element is insert molded. The ceramic glass block is mounted in a heater housing which includes a lower draft opening below the ceramic glass block and an upper air outlet above the ceramic glass block. When a voltage is applied to the steel wire, heat is generated by the wire and is absorbed and radiated by the ceramic glass block. Cool air is drawn into the draft opening in the housing and up past the ceramic glass block whereupon it exits the air outlet heated by the ceramic glass block. The heater is efficient because the ceramic glass heats very quickly and continues to radiate heat for a period of time after the voltage is removed from the steel wire. It is safe because the hot electric heating element is contained within the ceramic glass where it cannot contact flammable items.

Abstract: An electric baseboard heater includes a ceramic glass block within which a steel wire electric heating element is insert molded and which is provided with several through holes for convective movement of air through the block. The ceramic glass block is mounted in a heater housing which includes a lower draft opening below the ceramic glass block and an upper air outlet above the ceramic glass block. The glass block is preferably mounted so that one of its faces is exposed by the housing. When a voltage is applied to the steel wire, heat is generated by the wire and is absorbed and radiated by the ceramic glass block. Cool air is drawn into the draft opening in the housing and up through the through holes in the ceramic glass block whereupon it exits the air outlet heated by the ceramic glass block. The ceramic glass block is advantageously mounted at an angle in the housing to provide an aesthetically pleasing appearance while at the same time increasing the convective movement of air through the heater.

Abstract: Electric heating apparatus having at least one electrical heating resistor (24) arranged in a body (1) of sheet metal provided with an air inlet in its lower part and an air outlet in its upper part. The body (1) is formed by a double-walled hollow element in the form of a trough (2, 3) provided with end walls (14, 15) and at least one opening (12) for the entry of air and defining a first space (20) for the admission of air. The electrical resistor (24) is mounted on the concave part of the double-walled element in the form of a trough (2, 3) on the exterior of the latter. A perforated panel (30) is arranged on the concave wall and defines with the latter a second space (33) for the heating of the air by convection and for the direct radiation of the heat by the resistor through the perforations in the perforated panel.
