A method and apparatus for providing uniform heating of substrates disposed within a processing chamber is provided. The apparatus includes one or more heating coils disposed in the processing chamber. The one or more heating coils are electrically coupled to a power source using heater rods. The heater rods are coupled to a socket on a distal end opposite the connection to the heating coils. The socket includes a feedthrough and a cooling plate configured to remove contaminants, such as methane, from the area surrounding the heater rod.
