Heated Driveways and Snow Melting Systems - How it Works

The Premier Snow Melting Cable

Snow melting heat cable. As one of the most durable, versatile and long-lasting radiant heat cables on the market, ClearZone heat cable is a trusted radiant snowmelt solution. The cable features a polyolefin outer jacket with fluoropolymer insulation, metal sheathing and twin conductors. Combined with the advanced snow sensor and controller/contactor panel, the rugged snow melting cable can be installed in virtually any snowmelt application, and can even withstand the heat and compression of new asphalt installations.


Industry Leading Warranty

Warmzone offers the premier heat cable that carries one of the industry's most comprehensive 10-year warranties. Warmzone also manufacturers snow melting cable that is designed specifically for hot asphalt installations. Simply put, Warmzone snow melting cable is the trusted heat cable of choice among professional builders, and the inclusive customer services such as free training, installation support, system design, etc., are unparalleled.


Snow Melting System Control Unit

Snow melting system controller. Electric heated driveway systems with a pavement-mount snow sensor utilize a small wall-mounted control unit to power the snow melting system. The master controllers include line and load terminal blocks and operating contactors.


The snowmelt system controller features a built-in, easy-to-use programmable timer and digital operator interface with manual override capability. The unit is compact, durable and efficient, further complementing the overall performance of the ClearZone snowmelt system.


Using readings from temperature and moisture sensors, the controller ensures economical control of power consumption when keeping outdoor areas free of ice and snow. A moisture sensor is installed in the surface of the driveway. As soon as moisture is detected, the controller activates the snow melting system. Once the sensor has dried out, the thermostat immediately switches off the heating system.


Radiant Snowmelt System Activation Device

Snow melting system aerial snow sensor. Most Warmzone radiant heated driveway systems utilize an aerial-mounted snow sensor. This highly sophisticated, yet durable device automatically activates the driveway snowmelt system when certain conditions are met, and has several notable features, including: adjustable temperature trigger point, adjustable delay off cycle, upgrade-able remote activation, and it is smart-system compatible.


Pavement-mounted snow switches are also available, but are more commonly used in commercial applications. These devices allow the radiant snow melting system to be 100 percent automated, activating only when it snows. Manual mode allows you to activate the system in case the wind blows snow on the driveway or ice forms due to wind or shade.


Installation Notes

A certified electrician is required to hook up power to the control unit, but the rest of the system can be installed by any contractor. Cold leads are wired to the master control unit and then run to the radiant heating cable. The cold leads (come pre-spliced) are spliced to the heating cable, and the cable is laid out over the driveway or walkway to be heated.


Technical Specs of ClearZone Heat Cable

ClearZone cable is UL listed and consists of a twin conductor with FEP/XLPE insulation. Its polyolefin jacketing provides flexibility and durability, as well as UV protection. The radiant heating cable is rated at 220° Fahrenheit and is designed to produce 30-50 watts per square foot, providing the quickest response time among snowmelt systems.

Automated Driveway Heating

  Heated driveway systems provide reliable, maintenance-free snow removal.


Heated driveway and snow melting systems feature energy efficient, maintenance-free automated operation. The electric radiant heating systems detect precipitation and automatically switch heat on and off as needed.


ClearZone heating cable is the most durable radiant snow melting cable available and comes with a 10-year manufacturer warranty. The cable distributes heat evenly to the structure, providing a heated driveway and/or sidewalk that is kept free of ice and snow throughout the winter.


The fully programmable snow melting system makes labor-intensive snow shoveling and the use of harsh chemicals and salting a thing of the past.


Radiant heated driveway systems also increase the life span of the driveway by eliminating salt corrosion, frost damage, and potential damage from snow plows and other manual snow removal methods.
