Abstract
Abstract The invention adds liquid solar heating to conventional house construction without altering the plans. Sections of moulded polyester resin embedding p.v.c. pipes connect together to provide a continuous liquid pathway which is hidden from view. The sections are artistically styled, obviating the unsightly appearance of present day solar equipped homes. The arrangement is very inexpensive, yet durable, and not subject to glass panels and its attendant breakage or the use of expensive copper tubing. The entire roof is a collector and different parts of the roof are exposed to the direct sunlight at all times of the day. The solar sections actually replace the shingles, tile or other outer coating of the conventional roof for new construction. Hence, the solar section is integral with the house, making it more stormproof, yet workmen may walk over the roof.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
147 words
A solar heat collector roof unit of a type adapted to have liquid circulated therethrough comprising, in combination, an exterior roof surface module having an exterior roof facing positioned outwardly to receive directly thereon solar heat energy and shaped to rest side by side and interconnect with adjacent similar modules on exterior roof surfaces, said modules constructed of an outer darkened surface material disposed to receive solar energy and positioned adjacent and integral with a non-metallic body of a resin material capable of receiving from the surface material and transmitting solar heat energy therethrough to liquid, and piping passageways embedded in the resin material to provide a liquid flow path surrounded by said resin material extending through the interior of the body whereby solar heated liquid may be circulated to transfer efficiently solar generated heat collected by the darkened surface material to a building underlying said roof.
Claim 2
Dependent Claim
147 words
A solar heat collector roof unit of a type adapted to have liquid circulated therethrough comprising, in combination, an exterior roof surface module having an exterior roof facing positioned outwardly to receive directly thereon solar heat energy and shaped to rest side by side and interconnect with adjacent similar modules on exterior roof surfaces, said modules constructed of an outer darkened surface material disposed to receive solar energy and positioned adjacent and integral with a non-metallic body of a resin material capable of receiving from the surface material and transmitting solar heat energy therethrough to liquid, and piping passageways embedded in the resin material to provide a liquid flow path surrounded by said resin material extending through the interior of the body whereby solar heated liquid may be circulated to transfer efficiently solar generated heat collected by the darkened surface material to a building underlying said roof.
Claim 3
Dependent Claim
22 words
The unit of claim 1 wherein said roof module is moulded with pipes of different material than said non-metallic body embedded therein.
Claim 4
Dependent Claim
37 words
The unit of claim 2 wherein the modules are shaped with triangular cross section with the exterior facing of a plurality of side-by-side modules being stepped to present as said facing two surfaces with said surface material.
Claim 5
Dependent Claim
41 words
The unit of claim 2 wherein the module includes adjacent pipes connected together at one set of ends accessible from the module and the opposite ends of said pipes being recessed within the module and sealed inside said body of material.
Claim 6
Dependent Claim
26 words
A module as defined in claim 1 wherein the said body of material comprises polyester resin and said piping comprises p.v.c. pipes embedded in said resin.
Claim 7
Dependent Claim
16 words
A module as defined in claim 1 including glass bubble additives in the polyester resin body.
Claim 8
Dependent Claim
14 words
A module as defined in claim 1 with said exterior facing colored dark gray.
