Abstract
Abstract A radiant heater with a panel forming corrugations and having at least one heating element mounted on one of the corrugations. The panel is mounted at a distance from a surface partially defining a space to be heated for permitting fluid circulation between the panel and the space. The heating element is arranged in a groove defined at the apex of a convex surface defined by the corrugation, and is arranged facing the space defining surface. When a plurality of heating elements are provided, a thermostat having a set of contacts for each heating element is provided for actuating at least a portion of the elements at a predetermined temperature different from that for the other heating elements.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
118 words
A radiant heating panel for mounting on a wall surface of a space to be heated, comprising, in combination: a. a corrugated, heat radiating panel; b. means for mounting said panel adjacent to and spaced from a wall surface for permitting fluid circulation between the panel and wall surface, the corrugations of said panel including alternate concave and convex surfaces arranged facing a space to be heated partially defined by the wall surface, an apex of at least one of the concave surfaces being provided with means for defining a shallow, elongated groove open toward the wall surface; and c. an elongated heating element mounted in the groove and arranged facing and radiating directly onto the wall surface.
Claim 2
Dependent Claim
118 words
A radiant heating panel for mounting on a wall surface of a space to be heated, comprising, in combination: a. a corrugated, heat radiating panel; b. means for mounting said panel adjacent to and spaced from a wall surface for permitting fluid circulation between the panel and wall surface, the corrugations of said panel including alternate concave and convex surfaces arranged facing a space to be heated partially defined by the wall surface, an apex of at least one of the concave surfaces being provided with means for defining a shallow, elongated groove open toward the wall surface; and c. an elongated heating element mounted in the groove and arranged facing and radiating directly onto the wall surface.
Claim 3
Dependent Claim
32 words
Structure as defined in claim 1, wherein there are a plurality of heating elements, and at least an equal number of corrugations defining grooves, each heating element mounted in a respective groove.
Claim 4
Dependent Claim
31 words
Structure as defined in claim 2, wherein means are included for actuating at least one of the heating elements at a predetermined temperature different from that for the other heating elements.
Claim 5
Dependent Claim
50 words
Structure as defined in claim 2, wherein said panel includes a plurality of sections having edges arranged side-by-side, each section having associated therewith at least one heating element, and means including clamp means forming a guide channel connecting said sections together at said edges for permitting independent thermal expansion thereof.
Claim 6
Dependent Claim
44 words
Structure as defined in claim 2, wherein the space defining wall surface is a ceiling, and said means for mounting includes at least two longitudinal elements, each having a pair of spaced ends connected to said panel for suspending said panel from the ceiling.
Claim 7
Dependent Claim
52 words
Structure as defined in claim 1, wherein said panel includes a plurality of sections having edges arranged side-by-side, each section having associated therewith at least one heating element, and means including clamp means forming a guide channel provided for connecting said sections together at said edges for permitting independent thermal expansion thereof.
Claim 8
Dependent Claim
44 words
Structure as defined in claim 1, wherein the space defining surface is a ceiling, and said means for mounting is at least two longitudinally extending elements, each having a pair of spaced ends connected to said panel for suspending said panel from the ceiling.
