Installing a Heated Driveway

How is a Heated Driveway Installed?

Whether you’re looking to install a radiant snow melting system in concrete, asphalt, or under pavers, it doesn’t take much to make a heated driveway a reality. The important thing to remember is that a radiant snow melting system is only as good as its installation. That’s why Warmzone emphasizes customer support services such as free training and personal installation support. But how is a heated driveway system installed?

First, a Warmzone radiant heat expert will work with you to determine the specs and products that will best meet the specific needs of your custom project. After verifying receipt of the heat cable and system components, prepare the area where the system is being installed. Make sure there are no nails, sharp rocks or other items present that can cause damage to the heating cable.

Heated driveway installation with Mesh-Up supports

If you are installing a concrete heated driveway, install wire remesh in the area to be heated. Once the remesh is laid out, heat cable is then installed and secured to the remesh using zip ties.  This keeps the cable from shifting during the concrete pour. Mesh-Up plastic supports are then installed to lift the remesh and prevent the heat cable from resting on the ground. (The heat cable should be about two inches from the finished surface.)

With the Mesh-Ups installed and the cable secured to the remesh, concrete can now be poured over the heating cable/mats. Take care to not damage the heating cable. A typical slab is 4-inches thick. Follow your concrete contractor’s installation methods and follow all building codes. The heating cable is to be within 2-inches of the finished surface.

Most heated driveway systems utilize an aerial mount snow sensor to activate the system. This is typically installed at the roof’s edge where it has open access to the elements. When precipitation is present and the temperature is below the set point (usually set at 39°F), the sensor signals the contactor panel and power is then sent to the heat cable.

Important Note: For warranty and safety purposes, it is necessary for a qualified electrician to connect the system.

General Tips for Using the ETO2 Controller for Snow Melting Systems


This article is intended as a  general guide to help users of snowmelt systems that utilize the ETO2 and ground sensor. For more detailed information, please refer to the Owner’s and Installation Manual.

The ETO2 is an electronic controller for fully automatic, economical ice and snow melting for outdoor areas. The controller is used for snow melting and roof deicing systems utilizing in-ground sensors.

The ETOG in-ground sensor detects both temperature and moisture and signals the controller when conditions warrant. The ETO2 unit then sends power to the cable, activating the snowmelt system and warming the driveway surface.

The ETO2 features an easily operated encoder button and backlit graphic display to ensure quick and easy configuration and simple indication of temperature, status, etc.

Preparing for Winter’s “Perfect Storm”

Getting the Most out of Your Snowmelt System During Extreme Snow Events

Your Warmzone snow melting system was designed according to ASHRAE standards, meaning it was designed specifically for typical winter conditions in your area – and then some. But every now and then Mother Nature unleashes a furious “perfect storm” of epic proportions that overwhelm even the most hardy winter-weather cities. Snow plows, public transportation and basic city services can be brought to their knees because of unusually low temperatures and record breaking snowfall. Even fully automated radiant snow melting systems are faced with some unique challenges posed by the extreme conditions. Fortunately, Warmzone snowmelt systems include features that allow you to better cope with winter anomalies such as an extreme snow event.

Tips – Preparing for an Extreme Snow Event

If you’re faced with a potential storm of record magnitude, follow the steps outlined below.

Timer: If you purchased a timer with your heated driveway system, use this manual override feature to pre-heat your driveway 2-4 hours before the storm hits. (Once the snow starts to fall, the snow switch will detect precipitation and automatically activate the system.)

Aerial Mount Snow Switch: If you don’t have a timer, you can still manually activate the system using the WS-AUX controller or the aerial-mount snow switch. To activate the system using the snow switch, flip the toggle switch on the side of the unit up so that it is in the ON position. This activates the system and begins pre-heating the driveway. (NOTE: Remember that the system will remain on until you return the toggle switch to AUTOMATIC or STANDBY.)

Control display panel for automated snow melting system

WS-AUX Controller: Activating the system using the WS-AUX controller is the most convenient method for pre-heating your driveway or walks. Turning the sensor override switch on the WS-AUX to the MANUAL ON position will activate the snowmelt system continuously. Pressing the MANUAL ON button on the WS-AUX will not trigger the sensor to run continuously but will initiate one “drying cycle.” This mode can be used to test the system or clear any remaining un-melted snow. This function allows the user to run a cycle without having to remember to turn the system back off. The sensor will initiate one drying cycle and revert to automatic mode, thereby making it ready for detection of the next storm. The MANUAL ON mode can be activated directly from either AUTOMATIC or STANDBY mode. The user may reset and clear the drying cycle by pressing STANDBY.

The WS-AUX will show the current setting of the manual override switch for the attached snow sensor. The sensor’s override switch will always take precedence over the WS-AUX setting. If, for example, the WS-AUX has placed the sensor into STANDBY mode and the sensor switch is moved to MANUAL ON, the WS-AUX will show a change to MANUAL ON mode. Whenever the sensor’s switch overrides the WS-AUX’s setting, then returns to AUTOMATIC mode, the WS-AUX will also revert to AUTOMATIC mode.

In-Ground Snow Switch: For those utilizing the pavement-mount snow switch, refer to page 6 and 9 of the ETO2 User’s Guide Programming Manual.

Working with the Controller

Pre-heat Your Driveways in Preparation for Record Snowfalls

Main menu of the snow melting system controller

In MAIN MENU of the controller, turn the dial to scroll down to SETUP (as seen on page 6 of the User Manual). After selecting SETUP, scroll down to FORCE HEAT and push the dial in to select. This will then activate the system.

Naturally, you do not want to turn the snow melting system on too late or too early, so follow the local weather reports and make your best guess as to when the storm’s first snow will fall. It is recommended to begin pre-heating your driveway (or sidewalks) 2 to 4 hours before any excessively large storm hits. This gives your system a “head start” that will help it to keep up with the unusually heavy snowfall.

Remember, pre-heating the driveway is not necessary in most other cases. Your automated snow melting system was designed to effectively handle typical winter storms in your area. The steps outlined here are simply offered as suggestions to help you cope with the occasional record-breaking snow storm.

Example of dialogue seen on screen of the snowmelt system controller. The heat will stay on the amount of time the designated in the AFTERRUN mode. Once the FORCE HEAT cycle is complete, the device will default back to AUTOMATIC mode. The falling snow will then keep the system on.

Setting the Afterrun time in the controller menu

Adjusting the AFTERRUNTo adjust the AFTERRUN, remain in the SETUP menu.

Refer to page 10 of the User’s Manual.

Set the time for how long before the snowfall that you want to pre-heat the driveway area. Typical time ranges between 2 and 4 hours, depending on the storm.)

Installing a Radiant Snow Melting System (Part I)

Radiant Heated Driveways can be Installed in a Variety of Applications

Radiant heat snow melting systems can be designed, engineered and installed in any size, shape and type of driveway. From large parking lots to small driveways, steps or sidewalks, radiant snow melting systems can accommodate virtually all your snow melting needs. But the custom options don’t just stop there. You have a variety of options to choose from to fit your budget. You can heat your entire driveway area or just a strip down the middle, or perhaps just two 2-foot wide tire tracks. When you work with a trusted leader like Warmzone, your system will be designed and engineered so that it is the best customized radiant heat solution for your needs.

The ClearZone radiant heat system is one of the most proven snow melting systems on the market, which is why it’s not only a favorite among homeowners, but construction professionals as well. The heat cable can be installed in a variety of applications, including concrete, asphalt, and under pavers.

Concrete Heated Driveways and Sidewalks – New Pour

For years the ClearZone snow melting system has proven itself to be one of the most versatile and reliable radiant snow melting systems on the market. It is installed in numerous mediums, but concrete is the most common application for ClearZone heated driveways. The rugged heat cable is designed to withstand the stress of heavy concrete pours. During the installation, the ClearZone cable is laid out and then zip tied to the wire remesh. The concrete is then poured over the cable.

New Asphalt Construction Heated Driveways

Hot asphalt can damage some lower quality heat cables, but ClearZone cable is designed to withstand both the extreme temperatures and stress (from the compression) of newly poured asphalt. The radiant heating cable is laid out on the base surface (usually compacted sand), and the asphalt is then hand shoveled on top of the cable and then compacted.

For asphalt applications, it is recommended (but not required) to install 1-inch rigid insulation underneath the base surface. The insulation can be installed underneath the base surface or it can be laid on top of the base surface and the snow melting cable can then be secured on top of the insulation.

Brick Paver Driveways – Installation

Large heated paver driveway

ClearZone radiant snow melting systems are the most effective systems for heating under pavers. Installing a radiant snow melting system under brick pavers is also one of the easiest radiant heat installation methods. The heating cable is laid out on the base surface and the pavers are installed as normal, directly over the cables. Because the ClearZone cable has been tested and approved for wet conditions, the cable can come in contact with moisture without its performance being affected.

Repaving and Retrofitting Asphalt Driveway with Radiant Heat

Continued from Installing a Radiant Snow Melting System (Part I).

The ClearZone snow melting system is unique because it isn’t limited to new construction applications and can withstand the rigors of concrete pours and hot asphalt. If you have an existing asphalt driveway and intend to re-pave it, you can retrofit your driveway with a ClearZone snow melting system. The heat cable is secured to the existing asphalt with clips and nails and only needs to be embedded under just ½-inch of asphalt. The new asphalt is hand shoveled onto the cable and then compacted. ClearZone cable is simple to install and provides the best performance for heating asphalt driveways.

Fully Automated

The heat cable is wired to the master controller, which is usually mounted on a wall in the garage. An aerial or pavement mounted snow sensor is wired to the controller. When the sensor detects precipitation and the temperature is below a set point (usually 39°F.), it signals the controller, which then sends power to the heat cable to warm the driveway. While the system is fully automated, the controller also features manual override capability for times when you may need to melt a snow drift or ice that formed in a shady spot.

Tips for Successful Radiant Heat Installations

Installing a Radiant Snow Melting System

A radiant heated driveway is only as good as its installation, which is why it’s important to carefully follow best practices. As long as you remember a few simple tips, your snow melting system will be up and running in no time, and in good working order for years to come.

Installing heating cable in mats for heated driveway and sidewalk

This may seem like a no brainer, but it’s important to make sure you have the right products for your installation before you lay one foot of cable. Before every job, remember to check the voltage and the wattage of the heating cable (usually indicated on the box). If you’re unsure, you can always contact Warmzone for confirmation and/or recommendations.

A key to successful installations is to use a megohmmeter to perform OHM tests of the heat cable before removal from the box, during, and after the installation. This can save you some headaches in the long run and help to ensure a successful install. Be sure to document the results in order to establish the manufacturer’s warranty.

You have everything you need to construct the driveway of your dreams. Before you roll out any cable, here are a few rules to remember at installation time to prevent cable damage and get the most out of your system:

  • Never cut, cross or overlap the heating cable. Heat cable should not be altered under any circumstances, as it may cause overheating, resulting in damage to the cable.
  • Always embed the cable completely. Leave no air around the cable.
  • Make sure to embed the factory splice (where the heating cable and power lead meet).
  • Using a megohmmeter, perform OHM tests of the heat cable before removing the cable from the box, during the installation, and after the cable has been laid out.
  • Always run the cold lead in conduit (power lead for the heating cable) – it is not direct burial.

For asphalt applications, snow melting cables are normally covered by two inches of asphalt. To prevent heat damage, the asphalt should be allowed to cool to 220°F. (105°C.) before pouring directly onto the mats or cables. Ground sensors/tubes should not be exposed to temperatures above 176°F. (80°C.).

And, for a proper sensor installation, both ground and aerial activation devices require a clear, 360-degree “view” of the sky to allow snow to fall onto the sensor plate. If drifting is an issue where the snowmelt system is being installed, it’s best to install a ground sensor.

Of course, you should always read the Installation Manual and follow instructions. Or you can always call Warmzone at 888.488.9276 for on-the-job installation support and service.

Installing Radiant Heat in Asphalt

Asphalt Heated Driveways
When you combine the durability of asphalt with the automated snow removal capabilities of a radiant heated driveway, you get a winner. Asphalt heated driveways feature energy efficient, maintenance-free operation to keep your driveway safe and clear of snow and ice. If you’re considering a new asphalt driveway, a refresh, or even if you’re already enjoying the benefits of asphalt, there’s still time to include a radiant heated driveway in your plans.

Radiant heated driveway in Denver, Colorado. Asphalt and heated driveway systems go together for several reasons. First, they are durable, and engineered to withstand extreme heat, freezing and thawing. They also adapt easily to the environment. Asphalt pavements flex and “give” with significant settlements of frost heave, while Warmzone snow melting systems respond to the weather, operating only when conditions indicate that snow is on the way.

Applying hot asphalt over heat cable mats

ClearZone heat cable is specifically designed to withstand the hot temperatures of new asphalt construction jobs. In the case of a new driveway install, the asphalt is spread directly over the rugged ClearZone heat cable and then compacted. In one day, you can have a new driveway and a fully operational snow melting system. The embedded, fully automated, radiant heat snow melting system provides a discreet, reliable snowmelt solution for your driveway.

If you’ve already got an asphalt driveway, but it’s in sore need of repair, placing an overlay on the existing surface can be easily accomplished. As with the new pour, ClearZone snow melting cable can be installed just before the overlay. After a quick patch, a surface of about 2 inches is all you’ll really need for your driveway, and your new snow melting system installation.

If you’re not in the market for an asphalt refresh, no worries. Your existing driveway can be retrofitted with radiant heat. Grooves are cut in the existing asphalt, using asphalt saw-cut technology, and the heat cable is then placed in the freshly cut grooves. An epoxy topcoat is then applied as a sealant over the newly embedded cable. For additional traction and safety, a sand broadcast can be applied to the surface before the epoxy.

Fitted with a ClearZone snow melting system, an asphalt driveway is a cost-effective option for your home, and will last for years with only minimal maintenance. With radiant heat in the mix, you can also factor in all of the money you’ll save on snow removal services, snow melting chemicals and gas for your snow blower. And of course, there’s the gift of time. While your neighbors are out shoveling, snow blowing or tapping their watches waiting on their snow removal service, you’ll be in your car and on your way.

Don’t Get Spooked by Winter Weather

Meet Winter Head on with a Radiant Snow Melting System

You’ve no doubt heard about El Niño this year and the predictions of all the so called “weather experts”. Well, the truth is, we can never fully know what Mother Nature will bring us each year. Sure, we make the most educated guess possible, but it’s still just that – a guess.

So don’t let the doomsday sayers intimidate you into believing you’ll be lucky to escape winter alive this year. Halloween may be coming, but there’s no reason to be spooked by winter too. Certainly, it’s good to be prepared and keep some important items on hand for those times when you can’t make it to the store for a day or two, but chances are that winter will come and go, and spring will greet you with a smile – just like it did last year, and the year before.

But how you choose to deal with winter is up to you. For homeowners with steep driveways or business owners with outdoor steps, ramps and busy customer access points, installing a heated driveway or snow melting system is a pretty obvious solution. Radiant snow melting systems are fully automated and operate only when needed. That means that regardless what day or time the snow falls, the systems will respond to keep your driveway or walks clear of ice and snow during all of winter’s cold assaults.

Using salt to melt snow damages lawns and nearby shrubs.

Many consumers have opted to forego stocking up on salt and other snow melting chemicals prior to winter. Some have even been swayed not only by the convenience and effectiveness of radiant heat, but because of the added benefit to the environment. Salt and snow melting chemicals, while somewhat convenient in melting snow, are not so friendly on the surrounding landscape. The adverse environmental effects of salt and snowmelt chemicals leave scars year round. When spring arrives, the bordering grass and shrubs often reveal the ugly scars from the repeated use of snow melting chemicals during the winter.

But the greatest advantages of radiant snow melting systems are their convenience, clean, silent operation and round-the-clock reliability. And electric snow melting systems are maintenance free, saving your back from shoveling and your head from aching.

Avoid These Common Installation Mistakes!

Important Do’s and Dont’s when Installing Radiant Heat

Record Resistance Values in Warranty Card – First and foremost, keep your warranty valid by following the installation instructions and using a megohmmeter to measure the cable readings before, during and after the installation process as outlined. (The megohmmeter is a special type of ohmmeter used to measure the electrical resistance of insulators.) Measuring the cable’s ohm reading during the installation process provides the required warranty information and can reveal if any cable has been damaged during the install.

 ► Upon receiving the heat cable, check the ohm value shown on the cable tag. Write this figure in the space provided on the warranty card.
 ► Measure the ohm reading of the cable and record the results in the space provided on the warranty card.
 ► Lay the cable out and secure it so that it is ready to be embedded (under concrete, asphalt or pavers). Measure the cable’s ohm reading prior to being embedded. Record this value in the space provided on the warranty card.
 ► Apply the top layer and measure the ohm reading. Record the results in the space provided on the warranty card.
Cable Installation Tips
 ► Always maintain proper cable spacing. (Cables should be spaced no less than 2 inches apart (center-to-center) and no more than 4 inches, center to center. Minimum spacing is 2 inches. Maximum cable spacing is 4 inches.)
 ► Never allow the cables to cross or touch each other.
 ► Never cut the heating cable.
 ► In concrete and asphalt applications, the installed heating cable should be 2 inches from the finished surface. (The heating cable should never be resting on the ground prior to the pour.)
 ► Never run heating cable through an expansion joint. (Make sure the joint is tooled or cut NO deeper than 1¼-inches. The cable must be ¾ to 1-inch below the bottom of the joint.)
 ► Do not flex or strain the cable splice by pulling on the cable. All of the cable must be embedded, including the entire splice and 6-inches of cold lead.
 ► Avoid kinking or bending the cable sharply (which causes the insulation to “bubble” and pull away from the cable).
 ► When installing heat cable in paver applications, make certain that there is ½-inch of compacted paver sand or stone dust on top of the heating cables or mats. (Cables must be completely encased with no air gaps.)

Calculating the Operating Costs

Estimating the Cost of a Radiant Heat System

One of the most common questions among prospective buyers of radiant heat systems is: “How much will it cost to run the system?” While there are many factors that contribute to the answer of this question, we still can offer a formula that will help you determine what you can expect in terms of operating costs.

Keep in mind that the operating cost of a snow melting system will depend on the specifics of the system. Warmzone custom designs each snow melting system to ensure peak performance and energy efficiency. Radiant snow melting systems are designed specifically for the winter conditions in your area. Everything from altitude and average snowfall is considered as well as average winter temperatures. Before using the formula shown here to calculate the operating cost of your snow melting system, you’ll first need to know the kilowatt per hour rates of your local power utility company. These rates vary from region to region, so we used the average kilowatt per hour rate for the formula attached.

Warmzone’s experienced design team configures your snow melting system to best meet your snowmelt needs in the most efficient manner possible. The ClearZone snow melting heat cable is a proven industry leader that is available on spools or pre-spaced in mats for simple “roll-out” installation.

While systems vary, residential snow melting systems typically operate at 37 watts per square foot while commercial snow melting systems operate at 50 watts per square foot. The formula shown here would therefore change accordingly and you would multiply the square footage by 50.

Estimating the Cost for Operating an Electric Snow Melting System

 ❶ Determine the total square footage of the area that will be affected.
 ❷ Multiply the square footage by the heat required (e.g., 37 watts per square foot for residential). This will give you a total for the watts per square footage required.
 ❸ Divide this number by 1,000 to convert to kilowatts.
 ❹ Look up the kilowatts-per-hour rate from the local power utility company.
 ❺ Multiply the total watts-per-square-foot by the watts-per-hour.
 ❻ This gives you the cost per hour of usage for the snow melting system.

Warmzone to Release Instructional Videos

On Tap – Online Resource for Instructional Radiant Heat Videos

If a picture is worth a thousand words – as the saying goes – how much is a video worth?

“Invaluable”, said Troy Lindsay, general contractor and owner of PAE construction in Denver, Colorado.

While installing a radiant heat system is a not an extremely difficult task, it is still crucial to follow the correct procedures to ensure the system performs as intended. Considering the importance of proper installation, Warmzone extends the industry’s most extensive customer services. These customer offerings include personal installation support, detailed system design / layout services, and free installation training courses. These valuable services give professional builders distinct advantages when it comes to purchasing and installing radiant heat. The addition of an extensive online resource of instructional videos will further benefit contractors and simplify the installation process.

A veteran installer of commercial and residential radiant heat projects, Lindsay understands the value of instructional videos. “Having access to training videos will be an asset to installers everywhere,” he added. “It’s great being able to talk with electricians and designers at Warmzone during the installation process, but sometimes it really helps to be able to SEE what is being explained. Videos help to make things clear and can help keep Warmzone and installers on the same page and on track during the installation. Ultimately, the videos can save us time and money in the long run, and every contractor likes the sound of that!” he concluded.

How to videos for installing radiant heat from Warmzone

Warmzone senior training and support specialist, Jim Sage, reiterates the value of the soon-to-be-released video library.

“Many installers take advantage of our free installation training program, and after they complete our course and receive a certificate of completion, we can refer additional business to them. But sometimes we work with construction personnel who have not completed one of our training sessions. It’s one thing to explain a process over the phone, but going over the procedure and then having them view it online clarifies things and gives installers the knowhow to proceed with confidence. And the videos are not only advantageous to us and installers, they can also protect homeowners by providing clear methods and procedures that can help ensure the proper installation of their radiant heat systems.”

Watch for Warmzone’s new online video library launch, and take advantage of the information provided by Warmzone.

Before installing any heat cable, it’s important to know the ins and outs of radiant heat installation to maximize the performance of your system and ensure that the warranty remains valid. In addition to Warmzone’s free consultation and installation support, a wealth of information is also available online in Warmzone’s radiant resource center, where you can find articles, installation manuals and related information.

Basic Tips for Installing Snow Melting System
Cable Care – Extreme care must be used to ensure the cables/mats are not damaged when using sharp tools, wheelbarrows, shovels, rakes or heavy machinery.

Check Supply Voltage – Make sure that the supply voltage matches the voltage required for your specific snowmelt product.

Measure Cable Resistance – Remember to always measure, verify and record the actual resistance of the heating element throughout the installation process:
1.  Out of the box
2.  After laying the cable out
3.  After applying the surface material

Never cut the Heat CableHeat cable is resistance cable. When it is shortened it increases the wattage per foot of the cable. Altering the cable in this way can void the warranty and cause the heat cable to fail due to over-temperature.

Laying out Heating Mats – Unroll the heating mat on to the area you want to heat. Fasten the heating mat to the mesh reinforcement using tie-wraps, zip ties or cable strapping. Do not cause the heating cable of the mat to be compressed or strained.

Do not let Cables Touch – Never allow the heating elements to cross, overlap or touch.

Embed the Cable – Whether you’re installing in concrete, asphalt or pavers, make sure that the cable is completely embedded under the surface. If uncovered, it can malfunction in the area of exposure.

Embed the Power Lead – The power lead/heating cable splice and at least 6 inches of the power lead must also be embedded in the paved surface. The remaining power lead should be run through a conduit.

Making Turns with MatsHeating mats can be altered to accommodate drains, obstructions or bends in the layout. To make turns or alter the spacing of the heating cables in mats, only cut the tape – NOT the heating cable.

Ground Sensor Placement – The ground sensor must be placed between the heating cables within the heated area at least 3.3 feet (1 m) from the edge of the area. A minimum distance of 0.41 inches (1 cm) should be maintained between the sensor tube and the heating cable.

Aerial Snow Sensor PlacementAerial sensors should not be placed under eaves but where there is direct exposure to the open sky. Avoid areas that will have delayed or false readings.

Remember, Warmzone includes free installation support with your heated driveway system, so if you have any questions, call a radiant heat expert at 801.948.7577.
