Therma Products are available in 110 Volt and 220 Volt. ThermaWalk is designed to be installed in the fall and picked up in the spring. Just turn it on. Your mat will heat up and then start to melt the ice and snow. If you want your mat clear for the morning business, put it on a timer to come on 2-3 hours before sidewalk traffic starts.
Timers are available.
Therma products weigh 3.5 lbs. This will prevent any blowing and discourage any would be thieves. Therma products are strong enough to withstand the weight of 18 wheeler trucks. This will void the warrantee if damage occurs. In the off season it is suggested that you roll your Therma mats back up on the cardboard core that it was shipped with and store in a cool dry place.
