A mirror reflective element system includes a fourth surface electrically conductive element disposed at the fourth surface and in conductive continuity with a second or third surface electrically conductive coating of the second or third surface, respectively. A heating element at the fourth surface comprises a heating element substrate, which has first and second electrically conductive elements established thereat, with the conductive elements being electrically isolated from one another. The first conductive element generates heat to heat a portion of the heating element when powered. The second conductive element connects to the fourth surface electrically conductive element at the fourth surface of the rear substrate to establish conductive continuity between the second electrically conductive element and the fourth surface electrically conductive element when the heating element is attached to the fourth surface. The first and second conductive elements are accessible at the rear surface of the heating element substrate.
