Abstract: A radiant heating element is described. The radiant heating element includes: a top layer; a resistive element coupled to the top layer; a conducting element coupled to the resistive layer and the top layer; and a bottom layer coupled to the resistive layer and the conducting element. A peel and stick adhesive radiant floor heating element includes: a top surface; a thermo-resistive element coupled to the top surface and adapted to generate heat in response to an applied voltage; and an adhesive layer coupled to the thermo-resistive element. A method of installing radiant floor heating using a peel and stick adhesive radiant floor heating element is described. The method includes: removing a release liner from an adhesive surface of the heating element; and securing the heating element to a sub-surface.
