Abstract: An interconnected heated patio stone and system are disclosed, the stone consisting of a durable, heat-transmitting upper layer, and an insulating lower layer, a heating cable running within the stone, and having two interconnections at the edge of the stone. The interconnection has a bracket to connect with the cable, a receptacle for joining electrically to a bridging connector, and an electrical linkage making an electrical connection available. Each stone is connected with another by a bridging connector, which contains an articulated wire, and has a basin and cap at each end for electrically joining, in a sealed manner, with the receptacle. The system consists of two or more stones interconnected using bridging connectors, the whole system also connected to a power source.

Abstract: The present invention is a radiant heating tile system for installation on a supporting surface. The system utilizes a plurality of modular heating tiles, the modular heating tiles each being substantially flat and having a substantially equal thickness. Each of the heating tiles have parallel top and bottom surfaces, a plurality of sides and an electrical heating element. The heating tiles each also have an insulator layer covering the bottom surface of the tile. The electrical heating element of each of the heating tiles is electrically coupled to a male electrical coupling contained in a notch formed on a first side of said tile. The electrical heating element of each of the heating tiles is also electrically coupled to a female electrical coupling contained in a notch formed on a second side of said tile opposite the first side.
