Abstract
A heating element construction for a mesh mat used in an underfloor heating system. The heating element includes a heater wire having one or more conductors spirally wound around a center strand and an insulating jacket surrounding the conductor. The heater wire is doubled back on itself to provide two counterflow portions which are spirally wrapped around each other. The electric current flows in opposite directions in the two counterflow portions to cancel the electromagnetic field. A braided metal ground shield surrounds the heater wire. A protective outer cover surrounding the ground shield resists abrasion and water.
