Electric snow melting solutions have been around for more than 50 years in North America, and while the technology of the heating element has remained relatively unchanged, the quality and durability of surrounding materials have improved. Installation practices are also very similar, even 50 years later. Where technology has advanced is in the speed and accuracy of controls that instantaneously measure temperature, moisture, and precipitation by quickly activating. This has been key to lowering energy consumption, and now these controls are so accurate they are only energizing the heating cables when necessary.
Before beginning any snow melting project, there are general questions that must be asked so the manufacturer can make its best recommendation based on the needs and requirements of the system.
