An electric radiant heating system for heating building interior living and working space. The system comprises an electric resistance heating cable embedded in a cementitious thermal mass for transferring thermal energy to the thermal mass when an electric current is applied to the cable. The system utilizes a wall-mountable line voltage thermostat control to detect the temperature of the surrounding air, compare it to a selectable reference temperature, and perform a number of functions automatically depending on the results of the temperature comparison. High limit sensors, composed of bimetal strips, detect the temperature of the electric heating cable, sending a signal to the control means to interrupt power to the electric heating system when the electric resistance heating cable reaches a predetermined temperature. Cable-retaining hardware secures the electric resistance heating cable at regularly spaced intervals to the subfloor. The hardware holds portions of the cable above the subfloor to help suspend the cable in the cementitious underlayment layer. The cable is entirely suspended and surrounded by the underlayment during pouring of the cementitious slurry so that the cable does not contact the subfloor.
