Danfoss GX pavement heating systems operate automatically.  They detect when areas of your driveway or walkways require snow or ice melting, and switch the embedded heating cable on or off as required.  Subsequently, the heated driveway is kept free of ice and snow throughout the winter, making labor intensive snow shoveling or salting unnecessary.  Radiant heated driveway systems also increase the lifespan of the structure by preventing frost and salt damage.
