Abstract
Abstract In a hydronic heating system including a heating element that is a length of tubing that conducts water and is against a radiating metal plate, all mounted in a floor, wall or ceiling, the element being held by two spaced apart providing an elongated space for holding the tubing adjacent the plate, the metal plate is in two separate pieces that are attached to an edges of the spaced apart boards and combine when they abut each other at installation to provide a metal groove into which the tubing is inserted and held snugly with a substantial part of the tubing in direct intimate thermal contact with the metal.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
163 words
In a hydronic heating system including a heating element that is a length of tubing that conducts water mounted in a wall, floor or ceiling of an area heated by said system against a radiating metal plate, two spaced apart boards for holding said metal plate and providing an elongated space for holding said length of tubing adjacent said plate, said tubing being inserted into said space against said plate, the improvement comprising: (a) said metal plate is provided in two separate pieces, each of which is attached to an edge of one of said spaced apart boards, (b) said two separate pieces provide a metal groove that projects into said elongated space and (c) said metal groove accommodates the insertion therein of said tubing from one side thereof so that the tubing is held therein in intimate thermal contact with said plate metal, (d) whereby said plate is heated by conduction of heat from said tubing and radiates heat to said area.
Claim 2
Dependent Claim

In a hydronic heating system including a heating element that is a length of tubing that conducts water mounted in a wall, floor or ceiling of an area heated by said system against a radiating metal plate, two spaced apart boards for holding said metal plate and providing an elongated space for holding said length of tubing adjacent said plate, said tubing being inserted into said space against said plate, the improvement comprising: (a) said metal plate is provided in two separate pieces, each of which is attached to an edge of one of said spaced apart boards, (b) said two separate pieces provide a metal groove that projects into said elongated space and (c) said metal groove accommodates the insertion therein of said tubing from one side thereof so that the tubing is held therein in intimate thermal contact with said plate metal, (d) whereby said plate is heated by conduction of heat from said tubing and radiates heat to said area.
Claim 3
Dependent Claim
56 words
A hydronic heating system as in claim 1 wherein: (a) said plate has length, width and thickness and said length and width define a radiating surface of said plate and (b) said plate is mounted in said floor, wall or ceiling oriented with said radiation surface thereof parallel to said floor or wall surface adjacent thereto.
Claim 4
Dependent Claim
28 words

Dependent Claim
25 words
A hydronic heating system as in claim 3 wherein: (a) said two separate pieces each has a uniform cross-section shape transverse to the length thereof.
Claim 6
Dependent Claim
26 words
A hydronic heating system as in claim 4 wherein: (a) said two separate pieces each has the same uniform cross-section shape transverse to the length thereof.
Claim 7
Dependent Claim
18 words
A hydronic heating system as in claim 5 wherein: (a) said two separate pieces are substantially the same.
Claim 8
Dependent Claim
16 words

Claim 9
Dependent Claim
23 words
A hydronic heating system as in claim 3 wherein: (a) said two separate pieces are each made of a unitary sheet of metal.
Claim 10
Dependent Claim
33 words
A hydronic heating system as in claim 3 wherein: (a) said two separate pieces each also provides means for securing said radiating plate part thereof against said board to which it is attached.
Claim 11
Dependent Claim
46 words
A hydronic heating system as in claim 9 wherein: (a) for said two separate pieces, said means for securing said radiating plate part thereof against said board acts as a spring to compel said radiating plate part against said board to which said piece is attached.
Claim 12
Dependent Claim
35 words
A hydronic heating system as in claim 10 wherein: (a) for said two separate pieces, the area of said radiating plate part thereof is substantially greater than the area of said means for securing thereof.
Claim 13
Dependent Claim
28 words
A hydronic heating system as in claim 10 wherein: (a) said two spaced apart boards each has length, width and thickness and said boards are the same thickness.
Claim 14
Dependent Claim
45 words
A hydronic heating system as in claim 12 wherein: (a) for each of said two separate pieces, said means for securing said radiating plate part thereof against said board and said radiating plate part are spaced apart evenly to match the thickness of said boards.
Claim 15
Dependent Claim
32 words
A hydronic heating system as in claim 9 wherein: (a) said two separate pieces each provide said part of said metal groove, said radiating plate part and said means for securing part.
Claim 16
Dependent Claim
29 words
A hydronic heating system as in claim 14 wherein: (a) all of said parts of each of said two separate pieces is made of a unitary sheet of metal.
Claim 17
Dependent Claim
19 words

Claim 18
Dependent Claim
56 words
A hydronic heating system as in claim 9 wherein: (a) said two separate pieces are so formed that when attached to the edges of said spaced apart boards and laid on a surface with the separate pieces abutting, said metal groove is provided for holding said tubing in intimate thermal contact with said radiating metal plate.
Claim 19
Dependent Claim
27 words
A hydronic heating system as in claim 2 wherein: (a) said boards hold said plate radiating surface on the opposite side thereof from said length of tubing.
Claim 20
Dependent Claim
27 words
A hydronic heating system as in claim 2 wherein: (a) said boards hold said plate radiating surface on the same side thereof as said length of tubing.
Claim 21
Dependent Claim
33 words
A hydronic heating system as in claim 12 wherein: (a) said boards thickness is substantially greater than the outside diameter of said tubing and said boards are made of highly thermally insulating material.
