Natural stone panel with an integrated heating system and manufacturing method thereof

A method for manufacturing a natural stone panel with an integrated heating system for placing as a radiant heating flooring or facade, in direct contact with ground or wall, said method comprising:

• providing a stone tile;
• printing a heating layer on said tile, comprising a plurality of heating tracks;
• curing of the heating layer pattern and/or carbon film and/or carbon composite material at temperatures comprised between 100° C. and 150° C., for 10 minutes to 20 minutes;
• printing a second printed heating layer on said tile, comprising a plurality of distributing tracks;, wherein the distributing tracks comprise silver, copper, or other metallic elements;
• curing of the distributing tracks at temperatures comprised between 100° C. and 150° C., for 10 minutes to 20 minutes;
• and
• applying an insulating layer for providing thermal and electrical insulation between the printed heating layer and the ground or wall,
• wherein the heating tracks have been printed using a first ink, and the distributing tracks have been printed using a second ink, wherein electrical conductivity of the first ink is lower than electrical conductivity of the second ink, and
• wherein the printed heating layer has two distributing tracks for each heating track perpendicularly positioned in relation to said two distributing tracks to define bus bars by said distributing tracks.
