The engineers at Heat Trak, LLC have taken great care to develop a durable, safe and effective snow and ice melting system. The HeatTrak® products are made of an electrically operated heating element sandwiched between two protective surfaces of non-slip rubber, making them as durable as automobile tires and allowing them to endure harsh wear. The HeatTrak® products plug directly into any standard 120V or 240V outlet using its own equipment leakage circuit interrupter (ELCI).
