Installation Tips – Installing a Snow Melting System in Asphalt

Installation Tips for Installing Snow Melting Heat Cable in Asphalt (Quick Reference Guide – Article 1 in a Series of 3)

Remember to check the element resistance and the insulation resistance of the heating cable/mat at the recommended intervals:

  1. In the box: Write the values on the warranty card.
  2. After being laid out: Write the values on the warranty card.
  3. After being covered: Write the values on the warranty card.
  4. Record your readings in the installation manual.
  • When laying out the cable, DO NOT allow heating cables to touch, cross, overlap or get bunched up. Minimum allowable spacing is 2 inches.
  • Do NOT place asphalt that is higher in temperature than the cable’s maximum rated temperature on the heating cables.
  • Heating cables should be securely fastened so they do not move or shift during the embedment process.

Applying hot asphalt over heat cable mats

  • Do NOT use a track application machine on the asphalt. Rubber tire applicators are okay as long as the asphalt temperature is below the maximum rated temperature for the heating cables.
  • The operating weight of the asphalt roller should not exceed 1,000 pounds. (The heat cable is designed to handle 8.9kN before the insulation is damaged, which will cause the cable to fail.) NOTE: A walk-behind roller imparts a force of between 5-18 kN.
    • Use a small power roller to compact asphalt over cable on sand, concrete, or ½-inch aggregate. A smaller roller will take more time, but decreases the chance of damaging the heating cable.
    • A roller with 30 kN or less is allowable when heating cable is in concrete and the concrete is then covered is asphalt.
    • When compacting/rolling on a grade, do not stop the roller. Stopping and resuming the roller may stretch and break the heat cable.
  • Do NOT dump large quantities of asphalt on small sections of the heating cables. Doing this may cause damage to the cable because of excessive, focused heat. Ideally, the asphalt should be applied by hand.

Installing a heated asphalt driveway

  • Do NOT cut or alter the heating cable. Mat tape may be cut, but the heating cable must never be cut.
  • Embed all of the heating cable and the splice in the asphalt. Allow asphalt to cool to a temperature of approx 212°F (100°C) before applying directly over the cable and splice.

Installing the cable splice in asphalt.

  • Manually lay the asphalt and spread the material evenly around and over the heating cables.
  • Heating cables are normally covered by 2-inches of asphalt. Leave a buffer of 4 to 6 inches of unheated asphalt around the edge of the heated area. This allows for adjustment of paving surface edges without damaging the heating cable.
  • Handle heating cables carefully – use extreme care with tools such as shovels, rakes and wheel barrels to avoid damaging the cables.
  • Verify cable integrity by checking resistance often during installation.
  • It is important that the snow melting system be wired by a licensed, qualified electrician and in accordance with local laws, codes, regulations, and NEC guidelines.
  • Ground sensors/cups should not be exposed to temperatures above 80°C (176°F).
  • A perimeter of a maximum of 12 inches of asphalt should exist around the embedded cables. This allows for adjustment of the paving surface edge without damaging the heating cable.

Installation Tips for Installing a Snow Melting System in Concrete (Quick Reference Guide – Article 2 in a Series of 3)

Remember to check the element resistance and the insulation resistance of the heating cable/mat at the recommended intervals:

  1. In the box: Write the values on the warranty card.
  2. After being laid out: Write the values on the warranty card.
  3. After being covered: Write the values on the warranty card.
  4. Record your readings in the installation manual.
  • Ensure that all sharp stones and debris are removed from the area where the heating cable will be installed.
  • Place the remesh in preparation of the concrete pour.
  • Lay the cables/mats according to the plan and fasten them to the remesh or rebar (using plastic zip-lock ties) so that they do not move during the concrete pouring.
  • Do NOT allow heating cables to touch, cross, overlap or get bunched up.

  • Do NOT cut or alter the heating cable. Mat tape may be cut, but the heating cable must never be cut. View the video How to Make Turns with mats.
  • Heating cable/mats should be spaced at no less than 2-inches center-to-center and no more than 4-inches center-to-center. This also applies to adjacent heating mats.
  • Secure the heating cable to the wire mesh or grid using plastic zip ties. Make sure that the cable/mats and the wire mesh are secure so that they will not move or shift when the concrete is being poured.
  • The heating cable will need to be positioned 2-inches from the surface of the concrete. Use wire remesh and Mesh-Ups or concrete dobies/chairs to position the heating cable within 2-inches of the surface. The heating cable/mat should never rest on the ground.

Placing Mesh-Ups under cable and remesh

  • Do not allow heating cable to cross an expansion joint. Control joints are allowable under the following conditions:
    • The joint is tooled or cut NO deeper than 1¼-inches.
    • A 6-inch piece of ¼-inch angle iron is recommended to protect the cable any place where a control joint will pass over it. The heating cable is tightly strapped to the angle iron with plastic zip ties.
    • Mark the forms where the angle irons are located to accurately place the control joints.
    • The cable must be ¾ to 1-inch below the bottom of the joint. (Do NOT tool joints deeper than 1½ inches. Stay above heating cables.)
  • Embed all of the heating cable and the splice. The cold lead on the heat cable and mats is not rated for direct burial in earth and must be run through a conduit. (The first 6-inches of the cold lead and splice must be embedded in the heated surface.) See the illustration showing the installation of the heat cable and power lead.
  • Handle heating cables carefully. Use extreme care with tools such as shovels, rakes and wheel barrels to avoid damaging the cables.
  • Verify cable integrity by checking resistance often during installation.
  • It is important that wiring of the system is completed by a licensed and qualified electrician and in accordance with local laws, codes, regulations, and NEC guidelines.

To secure the cable, lay down a piece of thin wire mesh that fits the area to be heated. The wire mesh should be secured to the ground (with landscaping staples or pins) so it will not move during the embedment process.

Roll out the heating cable or mat and secure it to the wire mesh or grid using plastic zip ties. Heating cables should be securely fastened so they do not move or shift during embedment.

Heating cable should be spaced at no less than 2-inches center-to-center and no more than 4-inches center-to-center. This also applies to the cables in adjacent heating mats.

Contact paver or block manufacturer for total sand or dust depth needed for proper paver/block installation.

Sideview of heat cable installed under pavers

Embed all of the heating cable and the splice in a minimum of 1-inch (½-inch above and ½-inch below) of compacted material such as paver sand or stone dust. Cable and splice must be completely embedded. No air gaps around the cable or splice are allowable. Gauge of paver sand, stone dust or base material must be fine enough to completely encapsulate cable.

Do NOT drop pavers directly on the cable. (This can damage the cable insulation.)  If this occurs, stop installation and check cable integrity via ohm reading.

Handle heating cables carefully – use extreme care with tools such as shovels, rakes and wheel barrels to avoid damaging the cables.

Verify cable integrity by checking resistance often during installation.

It is important that this equipment be installed by a licensed and qualified electrician and in accordance with local laws, codes, regulation and in accordance with NEC guidelines.

If installing in permeable pavers or with pavers or blocks greater than 3-inches thick, contact Warmzone BEFORE installing.

ClearZone Heated Driveways

The Convenience of Fully Automated Snow Melting

Say goodbye to your snow shovel. Forget about that expensive snow removal service. A ClearZone heated driveway is a great way to stay ahead of inclement weather. With a radiant heated snow melting system, you’ll never have to worry about timing. Energy-efficient ClearZone systems are fully automated, maintenance free, easy to install and can be customized to meet the needs of just about any driveway or budget.

Paver heated sidewalk

Electric heated driveways use a high-tech snow sensor that signals the system’s controller to activate the radiant snow melting system when it detects precipitation and temperatures are below a set point (usually 39 degrees Fahrenheit). System response times are fast. Once activated, the electric heating cables generate instant heat to prevent snow and ice accumulation before it happens, keeping driveways and walkways clear and dry. Imagine waking up the morning after a snow storm to a clear, dry walkway and driveway. With an automated radiant heated driveway, it’s possible to see pavement all winter long, regardless of the conditions!
ClearZone’s super snow-clearing power renders the task of planning for snow removal obsolete. While there is a cost for the initial installation, it’s relatively insignificant when you compare it to the dollars you’ll save when you permanently dismiss your snow removal service. There are no contracts to sign, no flat fees, no wasted dollars and low returns during mild winters. Fully-automated electric radiant heat systems activate only when the conditions for snow are present, so you only pay for the resources (electricity) you need, when you need them. No more waiting for your service to show up, or stooping to shovel snow.

Best of all, you don’t need to build a new home to enjoy the convenience of radiant heat during the winter months. ClearZone radiant heat solutions are fully customizable to fit your requirements, and your budget. Some customers choose to install ClearZone radiant heating cable under the entire paved surfaces of their sidewalks and driveways to keep them free and clear from snow. Others choose to heat tire tracks or an 8-foot strip in the center of their driveway. ClearZone systems are also commonly installed in sidewalks, patios and steps, and other well-traveled areas around the outside of homes and businesses. The cable works equally well in new concrete pours, asphalt, pea gravel and stone pavers, and can even be retrofitted to your existing driveway and walkways, without compromising performance.

Warmzone snow melting systems include installation support and complete system design/layout services. Free installation training courses are also offered by Warmzone. Installers can complete courses on site at Warmzone’s corporate office or online.

Driveway Snow Melting Cable

Automated, Maintenance Free Heated Driveway Systems

We’re getting close to the time of year when we can put away the snow shovels and snow blowers. Or, were you one of the lucky ones who enjoyed the services of a radiant heated driveway this year?

Electric snow melting systems have proven their value in cold climates throughout the country, particularly during the brutal winter of 2009-2010. Designed for convenience and rugged reliability, these automated snowmelt systems lie in wait to ambush the white flakes as they silently descend from the gloomy sky. Okay, maybe I’m being a little dramatic and falling into my romance novel writing mode, but you get the point. The system melts the snow before it even has a chance to stick.

Driveway with heated tire tracks

Heated driveway systems include an aerial or pavement mounted snow sensor that detects the impending snow barrage and signals the control unit, which then sends power to the ClearZone heat cable, heating the driveway. After the storm, the driveway remains warm for a period of time, ensuring that it is clear of ice before it automatically shuts off. More often than not, this all takes place before you’ve even slipped on your Daffy Duck slippers or poured your first cup of Joe. Isn’t technology great?

In addition to the convenience (as if that wasn’t enough), heated driveway systems increase the value of your property and are friendly to the environment. Using renewable energy, electric heated driveways eliminate the need for abrasive, and often damaging, snow removal methods as well as the use of harsh snowmelt chemicals that harm nearby grass and other vegetation. So naturally, there’s no salty runoff from your driveway filling your street gutters. Ya gotta love that!

ClearZone heat cable is the preeminent snow melting cable on the market, and features the most impressive manufacturer warranty in the industry. Whether embedded in concrete, asphalt or underpavers, ClearZone cable has a proven track record for a wide variety of applications, and is a favorite among contractors and professional builders.

Homeowners from coast to coast are discovering the many advantages and enhanced safety from installing a radiant heated driveway and/or sidewalk.

Heated driveways can be customized to fit your driveway surface and shape as well as your budget. While most homeowners install radiant heat throughout their driveway surface, you can also choose more affordable options, such as installing heat cable in tire tracks. Or, simply heat only the areas that you use. Warmzone professionals will evaluate your needs and provide several options and a detailed drawing of your radiant heat system. If you are going down the radiant heat road, make sure you deal with respected industry leaders who will guide you along the way.

How Much Wood Could a Woodchuck Chuck in a Pile of Snow?

Could the Woodchuck Chuck More Snow than ClearZone Heat Cable?

Sure, it will probably never happen, but it is kind of fun to think about. Picture a beefed-up, squirrely little woodchuck taking on a snow storm versus the melting power of ClearZone heat cables. His furry little arms would be fast and furious tiny windmills as they scooped at the endless mounds of snow surrounding him. All the while the ClearZone heat cable would use the smart principles of radiant heat to work far less with far better snow melting results. The poor little woodchuck would perspire, breathe heavy, and wear out faster than a hippo running a marathon. Yet the ClearZone heat cable would sit calmly beneath the surface working silently to melt the snow above.

Maybe this scenario is proof that winter has been too long for me and my mind has started to wander to far off places because of the snow blindness and cabin fever. However, crazy or not, the idea of anything or anyone or any animal (poor little woodchuck) beating out the power of an automatic snow melting system when it comes to snow removal is frivolous. The snow melting systems that utilize ClearZone heat cables allow you, the user (or the woodchuck if he gets a good job to pay for it) to enjoy winter without the hassle of constant snow removal. It would give you and that wood chucking varmint a much needed rest.
