Radiant mat grid

1. An apparatus for heating or cooling structures comprised of:

(a) a plurality of radiant mat grid tiles forming a contiguous matrix of radiant mat grid tiles, each tile being square shaped with an upper surface and a lower surface;

(b) each tile having a plurality of protuberances affixed to the perimeter of each respective tile;

(c) each protuberance affixed by an attachment means for anchoring the protuberance to its respective tile so that each protuberance extends outside the perimeter of the tile;

(d) each tile also having a plurality of protuberance receptacles placed along the interior of the circumference of the tile juxtaposed in a position such that each can lock onto the protuberance of a neighboring tile;

(e) each tile having a plurality of weight bearing support knobs on its upper surface;

(f) each weight bearing support knob having a recess at the upper end;

(g) each recess containing a screw guide opening in its center;

(h) each tile having a plurality of tube cradles protruding vertically from the upper surface of the tile to support tubing;

(i) each tube cradle being immediately adjacent to one or more weight bearing support knobs;

(j) each weight bearing support knob adjacent to a tube cradle having an indented undercut notch in its vertical surface on each side adjacent to each tube cradle so as to allow tubing to snap into each tube cradle and hold the tubing in place;

(k) the contiguous matrix of radiant mat grid tiles for covering a desired part of the floors, walls, sides or ceiling of a structure to be heated or cooled;

(l) a length of tubing inserted into a plurality of tube cradles on each tile comprising the matrix of radiant mat grid tiles;

(m) the tubing being snapped into the indented undercut notch in the vertical surface of each weight bearing support knob adjacent to each tube cradle the tubing is placed on;

(n) the tubing connected to a pumping manifold means for pumping a liquid to enable the circulation of a heated or cooled liquid through the tubing;

(o) the matrix of tiles covered with an over-pour material.

2. The apparatus in claim 1 wherein the over-pour material is instead covered by an upper surface comprised of an efficient heat diffusion material.

3. The apparatus in claim 2 wherein the upper surface comprised of an efficient heat diffusion material contains dimples and recesses on its bottom surface which mate to the knobs and seat into the recesses of the underlying radiant mat grid tiles.

4. The apparatus in claim 2 wherein the efficient heat diffusion material comprising the upper surface placed over the radiant mat grid tiles is affixed to the radiant mat grid tiles by an attachment means for affixing them extending through a plurality of available screw guides in knobs extending from the upper surface of radiant mat grid tiles which have not already been used to attach the radiant mat grid tiles themselves to the underlying surface to which the radiant mat grid tiles are affixed.

5. The apparatus in claim 2 wherein the attachment means for anchoring the efficient heat diffusion material comprising the upper surface placed over the radiant mat grid tile is also used to penetrate through the same screw guide units used to anchor the radiant mat grid tile itself onto the underlying surface to which the Radiant Mat Grid tiles are affixed.

6. The apparatus in claim 2 wherein the radiant mat grid tiles comprising the matrix can be un-assembled and re-assembled as necessary.

7. The apparatus in claim 1 wherein each tile is of a polygonal shape.

8. The apparatus in claim 2 wherein each tile is of a polygonal shape.
