Abstract
Abstract In a solar water heater a heat absorbing collector panel is made to inverted box rib or corrugated shape to match other roofing panels. Conduits are secured to the flanks of box ribs or the crests of corrugations. A translucent cover of complemental box rib or corrugated shape rests on the metal sheet in register with it on strips of insulating material all around the area of the heater.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
97 words
A solar heat collecting panel of the kind comprising a collector plate, conduits, for conveying liquid, fixed to the collector plate and a solar radiation transmitting cover spaced from the collector plate, characterised in that the collector plate is made of metallic sheet formed to box rib or corrugated shape, the conduits are fixed to the underside of upwardly projecting ribs or corrugations and the cover to the panel is continuous over the panel, is shaped to be complemental to the collector plate, and has its ribs or corrugations in register with those of the collector plate.
Claim 2
Dependent Claim
97 words
A solar heat collecting panel of the kind comprising a collector plate, conduits, for conveying liquid, fixed to the collector plate and a solar radiation transmitting cover spaced from the collector plate, characterised in that the collector plate is made of metallic sheet formed to box rib or corrugated shape, the conduits are fixed to the underside of upwardly projecting ribs or corrugations and the cover to the panel is continuous over the panel, is shaped to be complemental to the collector plate, and has its ribs or corrugations in register with those of the collector plate.
Claim 3
Dependent Claim
31 words
The collecting panel claimed in claim 1 in which the collector plate and the cover are shaped to conform to the shape and pattern of the roof covering of a building.
Claim 4
Dependent Claim
25 words
The solar heat collecting panel as claimed in claim 1 in which the top surface of the metal sheet is treated to absorb solar radiation.
Claim 5
Dependent Claim
100 words
A solar heat collecting panel comprising a sheet of metal formed as a roofing panel with inverted box ribs, conduits secured to the inside of the flanks of box ribs in heat conducting relationship, a solar radiation transmitting cover spaced from and continuous over the metal sheet and also formed to inverted box rib shape and so positioned that surfaces on the metal sheet are parallel to surfaces on the cover, insulating means sandwiched between the cover and the metal sheet around the area underlain by the conduits, and manifolds for feeding fluid to and leading fluid from the conduits.
Claim 6
Dependent Claim
100 words
A solar heat collecting panel comprising a sheet of metal formed as a roofing panel with inverted box ribs, conduits secured to the inside of the flanks of box ribs in heat conducting relationship, a solar radiation transmitting cover spaced from and continuous over the metal sheet and also formed to inverted box rib shape and so positioned that surfaces on the metal sheet are parallel to surfaces on the cover, insulating means sandwiched between the cover and the metal sheet around the area underlain by the conduits, and manifolds for feeding fluid to and leading fluid from the conduits.
Claim 7
Dependent Claim
95 words
A solar heat collecting panel comprising a sheet of metal formed as a roofing panel with sinusoidal corrugations, conduits secured to the underside of crests in the sheet in heat conducting relationship, a solar radiation transmitting cover also of sinusoidal shape spaced from and continuous over the metal sheet and so positioned that surfaces on the metal sheet are parallel to the surfaces on the cover, insulating means sandwiched between the cover and the metal sheet around the area underlain by the conduits, and manifolds for feeding fluid to and leading fluid from the conduits.
Claim 8
Dependent Claim
95 words
A solar heat collecting panel comprising a sheet of metal formed as a roofing panel with sinusoidal corrugations, conduits secured to the underside of crests in the sheet in heat conducting relationship, a solar radiation transmitting cover also of sinusoidal shape spaced from and continuous over the metal sheet and so positioned that surfaces on the metal sheet are parallel to the surfaces on the cover, insulating means sandwiched between the cover and the metal sheet around the area underlain by the conduits, and manifolds for feeding fluid to and leading fluid from the conduits.
