Abstract
Abstract An electric radiant heating device is self contained and is mounted on a surface of a room, such as on the studs or joists of a building and has an electrical resistance strip element of predetermined wattage spaced from the edges of and sandwiched between two thin pliable mylar sheets, with colored strengthening strips mounted along each edge of the panel, and a reflective surface mounted on the rear surface overlying the resistance strip.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
146 words
The method of making a radiant heating panel comprising positioning a first thin pliable plastic panel to overlie a pair of narrow plastic strips, each on an opposite edge of said first panel, joining said edge strips to said first panel, positioning a serpentine electrical resistance element on said first panel on the surface opposite said edge strips and positioned between said edge strips, overlying said resistance element with a second thin pliable plastic panel, joining said second panel to said first panel to hold said resistance element in position therebetween, positioning edge strips along opposite side edges of the outer surface of said second panel, joining said edge strips to said second panel, electrically coupling a conductor to opposite ends of said serpentine resistance element, and positioning a reflective surface on the outer surface of one of said outer panels and overlying said resistance element.
Claim 2
Independent Claim
146 words
The method of making a radiant heating panel comprising positioning a first thin pliable plastic panel to overlie a pair of narrow plastic strips, each on an opposite edge of said first panel, joining said edge strips to said first panel, positioning a serpentine electrical resistance element on said first panel on the surface opposite said edge strips and positioned between said edge strips, overlying said resistance element with a second thin pliable plastic panel, joining said second panel to said first panel to hold said resistance element in position therebetween, positioning edge strips along opposite side edges of the outer surface of said second panel, joining said edge strips to said second panel, electrically coupling a conductor to opposite ends of said serpentine resistance element, and positioning a reflective surface on the outer surface of one of said outer panels and overlying said resistance element.
Claim 3
Dependent Claim
37 words
The method of claim 1 wherein said reflective surface is provided by superimposing a third panel on the outer surface of one of said first or second panels, and providing a reflective surface on said third panel.
Claim 4
Dependent Claim
21 words
The method oF claim 1 further including forming the edge strip with a color different from said first and second panels.
Claim 5
Dependent Claim
33 words
The method of claim 1 wherein said heating panel is to be used in a structure containing joists and further including selecting the width of the resistance element to fall between consecutive joists.
