Abstract: The present invention relates to a thermal accumulation-transmission panel that comprises an improved porcelain stoneware and a manufacturing process thereof, for its use as a thermal accumulator and transmission element in heating devices. The thermal accumulation-transmission panel of porcelain stoneware of the invention is characterised in that it comprises a porcelain stoneware whose chemical composition comprises between 80.0% and 90.0% SiO2 and between 5.0% and 15.0% Al2O3, in that its geometry presents parallelepiped projections on one of its faces that permit the creation of natural convection chimneys and in that it has a thickness of at least 12 mm.

Abstract: The invention relates to an arrangement for the heating of porcelaneous stoneware plates for use as an accumulator and a radiant element for heating, comprising the use of porcelaneous stoneware plates having a rear cover of synthetic metal (1), which enable a heating element (3) to be joined to same in such a way as (i) to heat the stoneware plate through the incorporation of any type of electrical resistors (6) or the adjacent incorporation of a container for a fluid (4), such as water or oil, and (ii) to maintain heat irradiation once the actuation of the heater has been stopped.
