Abstract
Abstract The present radiant ceiling heating unit consists of two heating panels to a unit with the panels of each unit electrically connected by nonheating jumper leads which permits the panels of a unit to be mounted on a ceiling lengthwise between a pair of the ceiling joists or installed side-by-side each on an opposite side of one of such ceiling joists and includes a clip for each pair of nonheating leads at an end of a panel to prevent the leads from being pulled from the panel end.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
160 words
An electrical radiant heating panel unit comprising a pair of flat electrically insulating panels of good thermal conductivity, a pair of electrical resistance-heating cables positioned entirely within one of said panels with one of said cables extending throughout one-half of said one of said panels and the other cable extending throughout the other one-half of said one of said panels, a third electrical resistance-heating cable positioned entirely within the other of said panels and extending throughout said other of said panels, a pair of nonheating lead wires extending from an end of said one of said panels and each connected to an end of one of said pair of heating cables and a second pair of nonheating lead wires extending from the other end of said one of said panels and an end of the other of said panels and each connected to a second end of said pair of heating cables and an end of said third heating cable.
Claim 2
Dependent Claim
160 words
An electrical radiant heating panel unit comprising a pair of flat electrically insulating panels of good thermal conductivity, a pair of electrical resistance-heating cables positioned entirely within one of said panels with one of said cables extending throughout one-half of said one of said panels and the other cable extending throughout the other one-half of said one of said panels, a third electrical resistance-heating cable positioned entirely within the other of said panels and extending throughout said other of said panels, a pair of nonheating lead wires extending from an end of said one of said panels and each connected to an end of one of said pair of heating cables and a second pair of nonheating lead wires extending from the other end of said one of said panels and an end of the other of said panels and each connected to a second end of said pair of heating cables and an end of said third heating cable.
Claim 3
Dependent Claim
92 words
An electrical radiant heating panel unit as claimed in claim 1 including a plurality of U-shaped insulating clips each having an opening, a pair of said clips each have one of said ends of said one of said panels inserted in said clip with the nonheating lead wires from that panel end extending through the clip opening, and a further one of said clips has said end of the other of said panels inserted therein and the nonheating lead wires from said other panel extending through the opening in said further clip.
