Plate-shaped heating element, in particular for floor heating

A flat element for floor heating systems, comprising:

• first and second substantially rectangular plates defining therebetween a cavity;
• spacing elements having a transverse dimension parallel to the plane of the plates, arranged in rows, said spacing elements extending perpendicular to the plane of the plates with said cavity and connecting the plates;
• a first row of said spacing elements being arranged on a first straight line, further spacing elements being arranged on further straight lines which are parallel with said first straight line;
• adjacent spacing elements on the further straight lines parallel to said first straight line being displaced to each other in the direction of said straight lines, the spacing elements of said further straight lines being arranged to form additional rows of spacing elements which are parallel to said first straight line;
• first and second fluid connections, at diametrically opposing corners of said heating element, communicating with the cavity, the fluid connections being oriented such that fluid flow through each connection is substantially parallel to the plane of the plates, said first fluid connection lying along said first straight line said fluid connections being located at substantially 45.degree. with respect to respective sides of the plates;
• said spacing elements being so disposed as to preclude an unimpeded straight line flow path between said first and second fluid connection;
• a spacing element closest to said first fluid connection being located on the first straight line.
