How does the heat transfer from the cable to the paver surface?

The Heatizon pedestal paver system uses an custom engineered aluminum insulated pan that sits directly beneath each paver. The Hott-Wire heating cable runs inside the pan, and because the pan is insulated on the underside, heat is directed upward into the paver rather than lost downward. This focused transfer makes the system more energy-efficient than systems without directional insulation, and allows the paver surface itself to act as the melting surface.
