The reason the HTM24-15B heated mat needs to be so durable is so that the ice and snow that accumulates in sidewalks, entryways and walkways are properly melted. Also, these mats can be left out all winter so that your entryways are constantly safe for foot and wheelchair traffic.
The Heat Trak HTM24-15B measures 24 inches x 15 feet and is compatible with 240 volt outlets. It can be directly plugged into a standard 240 volt outlet because it has its own equipment leakage circuit interrupter. Also, if you use calcium chloride, your sidewalk will be eaten away over time but the heated traction mat actually helps preserve sidewalks.
