Understanding the Power Requirements for a Heated Driveway

Prior to Installing a Snow Melting System

If you’re looking to install a radiant heated driveway for a residential or commercial property, one of the first things you need to confirm is whether you have the necessary power requirements. In most cases, having the power needed to run an efficient radiant snow melting system is not a problem; however, prior to any installation, contractors should work with electricians to determine that the site will have the necessary power for heating the snowmelt area.

Contractors can use the following general information to quickly asses the power needs of a snow melting system. One 30-amp breaker supplies enough power to heat a 170-square foot area. To heat a driveway of 350-square feet, two 30-amp breakers (or one 60-amp breaker) would be needed. Homeowners can check their home’s main breaker panel to see the power coming into the house. (Typical homes feature either two 100 amp panels or two 200 amp breakers. These are located at the top of the main breaker box, above the main breaker panel.)

If you’re unsure of the square footage of your driveway, no worries; ProLine Radiant can calculate that for you too. In most areas, using a special state-of-the-art technology, ProLine can measure the area of your driveway while talking on the phone with you. Our helpful staff will work closely with you to ensure that the square footage of the area is measured correctly and the power requirements are therefore calculated properly.

On rare occasions when there is insufficient power available to operate a large driveway heating system, the radiant heat system can be laid out in zones. Each zone is powered separately. As a storm first hits, zone 1 would power up and melt the snow in that area of the driveway. After zone 1, zone 2 would then activate to melt the snow in that area of the driveway. Talk to a ProLine representative at 866.676.9276 for more detailed information about zoning your heated driveway.

When it comes to determining the power requirements for heating a specific area and what power is available, remember that you don’t have to figure this out by yourself. ProLine’s experienced reps are happy to work with you to not only help you determine the necessary power requirements, but to design a system that best meets the customers’ specific snow melting and budget needs. ProLine provides complete system design services, so prior to any installation, customers will know the exact layout and power requirements of the system.

Determining the Operating Cost of an Electric Heated Driveway

Homeowners are also keen to know the general operating costs of a heated driveway. Because radiant snow melting systems are specially designed for the specific demands of the average temperature and snowfall of their location, no two radiant heat systems are exactly alike. However, there is a formula that can be used to help you determine the approximate operating cost of a snow melting system.

General Guidelines to Determine a Heated Driveway’s Operating Cost

  1. Determine the total square footage of the area that will be heated.
  2. Multiply the square footage by the heat required (37 watts per sq. ft. for residential). This will give you a total for the watts per square footage required.
  3. Divide this number by 1,000 to convert to kilowatts.
  4. Look up the kilowatts-per-hour rate from the local power utility company.
  5. Multiply the total watts-per-square footage by the watts-per-hour. This gives you the cost-per-hour of usage for the snow melting system.
  6. NOTE: Heating cables and mats are rated in total watts. If the snowmelt system is intended for a commercial application, then you would multiply the total square footage by 50 watts to get a total wattage required. (E.g., 5,000 sq. ft. x 50 watts = 250,000 watts required.)

Radiant heat provides a range of benefits for home and business owners. The operating costs of automated snow melting systems are typically less than that of hiring professional snow removal services, and can help to extend the life of concrete driveways and keeps them from being subjected to abrasive snow removal methods or harsh snowmelt chemicals or salt. And since the systems are fully automated, business owners can be assured that walks and parking areas remain free from snow and ice during winter storms, enhancing safety for patrons.

Beat the Fall Rush

Install a Radiant Snow Melting System early in the Summer

As contractors well know, the late season rush to complete projects can be hectic – to say the least. That’s why it’s important to encourage homeowners to begin their radiant heat installation projects as early as possible. Spring and early summer is the ideal time for construction projects, and it makes lives for professional builders a little less stressful as cooler weather looms on the horizon. Completing projects early in the summer also allows contractors to take on more business later in the season, increasing the earning potential for the year.

Completing a project in the spring and early summer is beneficial to home and business owners as well. Having a radiant heat system installed well before the arrival of Old Man Winter allows consumers to get familiar with their systems and troubleshoot any issues if necessary.

Heated paver driveway

Whether your customers are looking to pour new concrete or repair existing pavement, radiant heat installation is an excellent way to increase value and lengthen the lifespan of driveways from harsh snow melting chemicals and snow removal equipment. It’s a smart investment that can also benefit business owners by eliminating slick walkways and parking areas to greatly reduce the chances of injury liabilities from pedestrian “slip-and-fall” accidents. Radiant snow melting systems also eliminate the need for time consuming manual snow removal and the possible injuries and lost work time from shoveling.

With radiant heated driveways and walkways, you get energy-efficient, round-the-clock snow removal to keep areas clear of snow and safe for pedestrians. These automated systems operate silently on renewable energy and are maintenance free.

Radiant heat applications are extremely flexible and adaptable, offering homeowners many options to achieve their goals. ProLine will custom design each system to best meet the specific needs of the customer. Consumers have the option to heat entire areas, a strip in the middle of the driveway, or just two 24-inch wide tire tracks. The layout options are virtually limitless.

Snow melting systems can also be installed in existing concrete or asphalt driveways. Saw cut technology can be used to cut grooves in concrete driveways where the cable is placed. A special epoxy is then placed in the grooves, over the cable. To heat existing asphalt driveways, the heat cable is laid out over the old asphalt and then a new layer of asphalt is applied over the cable. ProLine offers special heat cable that is designed to withstand the extreme temperatures of hot asphalt applications.

To better understand the options available, contact ProLine for free consulting or a free estimate. ProLine has the experience and resources to provide contractors with top tier solutions at preferred pricing, all backed by industry leading customer services. And once you’ve installed one ProLine system, we can refer you for future projects in your area. Call 866.676.9276 today to learn more.

Making Ground Fault Protection Requirements Easy

An Easy, Affordable Solution for Ground Fault Protection

In accordance with the National Electrical Code (NEC), all electric snow melting, roof deicing and outdoor pipe heating systems require ground fault protection for safe operation. This often results in time-consuming and costly delays for installers because these breakers can be expensive and difficult to find. However, ProLine has taken steps to eliminate this issue and facilitate a quick, safe installation.

ProLine not only offers contactor panels with built-in ground fault protection, but also offers separate ground fault protection units with snowmelt systems and activation devices. These affordable units provide an easy-to-integrate solution to meet the NEC requirements for snow melting system ground fault protection.

Ground fault protection equipment enclosure

   Ground fault protection equipment enclosure.

ProLine offers two ground fault units: the GF-1 and GF-2. The GF-1 unit provides single-circuit protection and the GF-2 provides dual-circuit protection (for 120/208/240VAC circuits up to 60A). Unlike highly sensitive GFCI breakers, ProLine’s GF unit maintains a 30mA fault trip point to help prevent nuisance tripping. The unique design of the units allows installation of standard, off-the-shelf overload breakers into the customer load center. Installers simply size the breaker and wiring for the system (15A to 60A), and then install the GF unit between the load center branch circuit and the sensor/controller and heat cable. The overload breaker protects the wiring while the GF unit provides the ground fault protection.

The ground fault unit is housed in a rugged, NEMA 4X/IP65 rated enclosure, making it suitable for indoor or outdoor installation. The enclosure’s gasket-sealed front access door allows for easy testing and reset. All internal electronic components are specified for -40°C to +60°C operation. The enclosure is designed so that it can be easily surface-mounted near the load center or near the snow melting system, depending on the installer’s preference. The enclosure also features several “knockouts” to provide flexibility for installation and wiring. The base of the ground fault unit’s enclosure can accommodate standard ½ and ¾-inch conduit hubs. Four mounting holes outside the enclosure gasket make mounting simple while ensuring weather-tight performance.

Features

  • Easy installation; convenient access for wiring
  • Compatible with inexpensive, off-the-shelf overload circuit breakers
  • Provides true 30mA trip point GFPE protection
  • Meets NEC Article 426.28, 427.22, and CEC 62-300 requirements
  • Protects 120/208/240VAC systems up to 60A (#14-#6 CU-only conductor capacity)
  • Not Compatible With 277VAC or L-N-L 240VAC
  • UL listed (U.S. and Canada) NEMA 4X enclosure for indoor or outdoor installation
  • Sealed, hinged front cover that latches for easy testing and reset access
  • No overload rating means only two part numbers for simple stocking
  • Weatherproof and corrosion resistant enclosure
  • Operating temperature range of -40°F/C to +140°F/+60°C

The GF-1 and GF-2 can be used directly with the WS-2C, WS-5C and WS-8C aerial mount snow sensors. The ground fault units can also be used with ProLine contactor panels, switches, and any system up to 60A. Since the overload protection is provided by the load center breaker, only two GF models are required to cover the full range of 15A to 60A, one or two circuits. This allows ground fault protection with kitted systems without having to identify the customer’s load center type or researching whether a combined overload/GFPE breaker is available and how long it will take to receive.

Including a ground fault unit gives installers all the components necessary to complete the snow melting system so that it is ready to install. And the GF unit provides a ready-made solution when installing or retrofitting a snow melting system in an older facility that was wired well before the term “GFPE” was coined. It’s an easy upgrade to help bring an existing system into compliance with modern code requirements. As your radiant heat partner, ProLine makes the process of installing a snowmelt system as easy as possible.

How is a Heated Driveway Installed?

Tips for Installing a Radiant Snow Melting System

Radiant driveway heating systems can be installed in a variety of applications, including concrete, asphalt, or under pavers. While ProLine Radiant offers industry leading products and preeminent customer service, perhaps the most important thing to remember is that a radiant snow melting system is only as good as its installation. For this reason, ProLine emphasizes its free installation training and personal installation support services. These services help to ensure a successful installation and satisfied customers. But just how are heated driveway systems installed?

Snow melting system and components overview.

Click on image to enlarge the illustration.

After receiving the heat cable and system components, verify the shipment and make sure all the correct materials have been received. Next, prepare the area where the system is being installed by making sure there are no nails, sharp rocks or other items present that can damage the heating cable.

For concrete heated driveways, install wire remesh over the area that will be heated. After laying out the remesh, place the heat cable over the remesh and use zip ties to secure it to the remesh. This keeps the cable from shifting during the concrete pour. Then place plastic Mesh-Up supports under the remesh (the remesh “clicks” into the slots cut out in the top of the Mesh-Up) to prevent the heat cable from resting on the ground. (The heat cable should be about two inches from the finished surface.)

Heated paver sidewalk

Use a Megger to repeatedly check the heat cable during the installation. Do this again, just prior to pouring the concrete. If the readings look good, begin pouring the concrete over the heating cable/mats. Be very careful when using shovels and rakes during this process. These metal tools can damage the heat cable, so care must be taken.

A typical concrete slab is 4-inches thick. Follow your concrete contractor’s installation methods and adhere to all building codes. (Again, the heating cable should be approximately 2-inches from the finished surface.)

Most automated driveway heating 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 adjustable set point (usually set at 39°F), the sensor signals the contactor panel and power is then sent to the heat cable.

Snow Melting Systems – Reliable and Easy to Customize

Versatile Snow Melting Systems

While many contractors have not installed or worked with radiant heat systems, those who have installed these systems have discovered the relative ease of installation and improvement to their bottom line. And whether you’re installing a heated driveway, heated floors or a roof deicing system, these advanced systems can be easily customized to meet the specific needs of your project. And radiant snow melting heat cables can be installed in just about any medium, including concrete, hot asphalt, or under pavers.

Because of their versatility, radiant snow melting systems are not only ideal for new construction projects, but also for increasing the comfort, convenience and value of existing homes. ProLine can design systems that best meet the unique demands of your clients, whether it’s a retrofit or new construction application.

ProLine snow melting systems are designed for use in a wide variety of mediums and applications, including concrete, asphalt and pavers. The snowmelt systems can be installed to accommodate budgets as well as custom layouts. Snow melting systems can be used to heat entire driveways, tire track layouts, steps, ramps, sidewalks or porches, etc.

Installing Radiant Heat in Asphalt

One of the most popular, affordable, and easy to install mediums for radiant heat is asphalt. Where asphalt gives and flexes according to a wide-range of seasonal temperature changes, the durable, specially designed ProLine heat cable ensures consistent performance to effectively keep driveways clear of snow and ice. The automated systems also feature manual override capability to deal with snow drifts of areas where water may have pooled and refrozen.

Retrofitting asphalt driveway with radiant heat

The cable’s external jacket is designed specifically for installation in hot asphalt applications, so ProLine’s asphalt heat cable is rated up to 460 degrees for up to 10 minutes. (For additional technical specs and installation information, please refer to the Snow Melting Cable and Mats Data Sheet or Installation Manual.)

ProLine snow melting heat cable is available off the spool or pre-spaced in mats. The mats can be rolled out for quick and easy placement over the area to be heated. Cable off the spool allows greater flexibility for custom shapes and hard-to-reach areas of snow melting systems. In the case of a retrofitting an asphalt driveway with radiant heat, the cable is simply laid out over the existing asphalt and then asphalt is applied over the cable. A compacted layer of 2 inches is recommended. For detailed installation and compacting instructions, please refer to the installation manual.

In addition to offering industry leading heat cable and system components, ProLine also includes unparalleled customer services, including free installation training, installation support, system design and layout, and a wealth of instructional resources online, including “how to” videos. Whatever your goals, you’ll find a range of versatile, affordable radiant snow melting systems flexible enough to meet your goals.

A Few Helpful Installation Tips:

  • Heating cables should never touch, cross, overlap or get bunched up. Always allow 2 inches of spacing between each cable
  • For asphalt applications, check the maximum rated heat temperature of the heating cables before you apply hot asphalt and confirm that the asphalt does not exceed this temperature.
  • If you’re installing mats, but need to make individual runs of heat cable, simply cut the tape backing of the cable mats and then layout the cable accordingly. BUT DO NOT CUT THE HEAT CABLE.
  • Manually pour small quantities of asphalt on the heating cables and spread it evenly around and over the cables. Repeatedly applying small quantities of asphalt on the heating cables during installation helps to prevent any potential damage to the cable.
  • Always handle heating cables with care—especially when using tools such as shovels, rakes and wheel barrels to avoid damaging the cables. When using wheelbarrows to dump asphalt, lay down sheets of plywood over the cable to avoid damaging the cable’s outer jacket.
  • Using a Megger, repeatedly check the cable resistance during the various stages of the installation (as outlined in the installation manual).

A snow melting system is only as good as its installation; therefore, an understanding of the proper installation procedures and local laws, codes and regulations is vital. Call us toll-free at 866-676-9276 to learn more. Our professionals are always happy to answer any questions you may have.

Feedback from the Field

What Separates ProLine Radiant from the Competition? Ask Our Customers:

To all potential ProLine customers,

I am a landscape designer, located on the seacoast of New Hampshire. We get plenty of snow in the winter, and I truly believe that heated driveways and walkways are the next big thing for our area, as in some of the more dense residential areas there is often no place to put the snow. However, before recommending radiant heat to my clients, I needed to try it and live with it myself.

This fall, we installed ProLine heating cables in our driveway. So far we have had two storms, one mainly snow, and the other rain and ice. The driveway performed beautifully. During the snow storm, it melted the snow effortlessly. We had forgotten to put it on automatic so it was off during the first part of the storm. After realizing this, we turned the system on, but not before a couple of inches had already fallen, but it still managed to make up for lost time.

During the ice storm, the driveway was DRY, while everything else was covered in a skin of ice. Great success! I’m not much of a snow lover, but I’m actually looking forward to the next storm!

Heated driveway with brick pavers

Although I am thus far completely sold on the product, the purpose of this letter is really to rave about ProLine’s customer service and support. These days, good customer service is rare, and great customer service is almost nonexistent. ProLine’s service is in the “great” category. For a new customer, with limited experience in outdoor heating, their technical support was crucial. Having a video web chat with Jim and looking at the schematic of the job before we began was one of the reasons for the success of the project. But the step-by-step instruction was only a part of the support that ProLine provided. Throughout the process they were always in touch. Larry, the account manager, was always there to answer questions, even when he was on vacation!

Brandon visited the site twice to answer questions and offer support, and Jim was always on the other end of the phone to talk to my electrician when it was necessary. They seemed to anticipate our needs and fulfill them before we even knew what they were ourselves.

In my years as a homeowner and landscape designer I have dealt with all sorts of people on all sorts of projects, and the service and support that we experienced from ProLine was among the best. It was a breath of fresh air, and I look forward to hopefully doing a lot of business with them in the future.

Snow Melting Systems – Installation Tips

Premier Snowmelt Systems Backed by Unmatched Customer Service
Electric heated driveways continue to gain popularity among professional builders and homeowners alike as they discover the benefits of these maintenance-free snow melting systems. Featuring easy installation, reliable and energy efficient performance, electric snow melting systems offer environmentally friendly operation for clearing driveways, ramps, steps, parking lots and more of snow and ice.

ProLine Radiant’s fully automated snowmelt systems feature an advanced aerial-mount or in-ground snow sensor. When the sensor detects precipitation and the temperature is below the adjustable set point (typically set at 39°F), it sends a signal to the master controller that is usually installed on a wall in the garage. The controller then sends power to the embedded heat cable to warm the surface.

ProLine controllers for in-ground sensors are small (6×3½-inch), NEMA 1, wall-mount control panels that provide UL listed snow melting for large commercial and custom residential and applications. The controller also offers a feature allowing it to be controlled from an external signal (day/week timer, GSM-module or other signal source). The unit features a manual off/on switch (standby) so the heating system can be manually activated to melt snow or ice that occurs because of wind or shade, further enhancing safety.

For snow melting systems to perform as intended, they must be properly installed. Here are a few basic tips for the proper installation of radiant snow melting system heat cable.

Installing snow melting mats

Heating Cable – General Installation Tips:

 ► Maintain proper cable spacing. (Minimum spacing is 2 inches (center-to-center) and maximum cable spacing is 4 inches, center-to-center.)
 ► Do not allow the heat cables to touch each other.
 ► Never cut the heating cable.
 ► Make sure the heating cable is not resting on the ground prior to a concrete or asphalt pour. Secure the cable to remesh that is supported by Mesh-Ups or something similar. The installed heating cable should be 2 inches from the finished surface.
 ► In concrete applications, avoid running the heat cable through expansion joints. (The joint should be tooled or cut NO deeper than 1¼-inches, and the cable must be ¾ to 1-inch below the bottom of the joint.)
 ► Do not 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
 ► Do not bend the cable sharply. This may cause the insulation to pull away from the cable and eventually cause the cable to fail.
 ► 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 Radiant Heat Operating Costs

How Much will it Cost to Operate a Radiant Heat System?

A common question among homeowners looking to install radiant heat is “How much will it cost to run the system?” Of course, each snow melting or floor heating system is unique, and local utility rates vary throughout the country. However, there is a formula that can be used to give potential buyers a good idea of what the operating cost of their snow melting system will be.

Each ProLine Radiant snowmelt system is custom designed. To ensure optimum performance, each radiant heat system is designed specifically for the conditions of the area in which it is being installed. Everything from the altitude and average snowfall is considered as well as average winter temperatures. The experts at ProLine understand that a radiant heating system is only as good as its installation, which is why ProLine commits so much of its expertise to professional system design, as well as installation support and training. When it comes to complete service, you won’t find a more reliable provider than ProLine Radiant.

Heated driveway with brick pavers

To calculate the operating cost of your snow melting system, you’ll first need to obtain the kilowatt-per-hour rate from your local power utility company. These rates vary from region to region, so the rate shown here in the following formula uses the national average kilowatt per hour rate (12 cents) for the formula below.

  1. Determine the total square footage of the area to be heated. (The average American home has an 800-square-foot driveway.)
  2. Multiply the square footage by the heat required (37 watts per square foot for residential). This will give you a total for the watts per square footage required.
  3. Divide this number by 1,000 to convert to kilowatts.

Example (for heating an 800-square-foot driveway): 800 (square feet) x 37 (watts) = 29,600 (total watts).

29,600 divided by 1,000 = 29.6 kw per hour (This is what the power company will charge per one hour of operation.) The average utility rate is 12 cents, therefore: 29.6 x .12 = 3.55. The cost of operation would be $3.55 per hour.

ProLine Radiant’s professional designers configure your snow melting system to best meet your snowmelt needs in the most efficient manner possible. ProLine’s snow melting heat cable is a longtime, proven industry leader that has been installed in commercial and residential applications throughout Northern America. The heat cable is available on spools or pre-spaced in mats (with strips of tape backing) that can be rolled out on site, providing quick and easy “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.

ProLine’s radiant design team provides AutoCAD drawings of each system that includes all the power requirements and technical specs. Customers will know all the information you need prior to any installation taking place, including load calculations, number of breakers, breaker sizes, and so on. ProLine is committed to your success.

Troubleshooting Tips for Roofing Installers

Tips for Troubleshooting ProLine Low-voltage Roof Heating Systems

ProLine Radiant’s low-voltage,  roof deicing system has proven to be one of the most effective roof heating systems available. This efficient system is ideal for heating roof edges and valleys, as well as gutters and downspouts.

The thin, semi-conductive polymer heating element is self-regulating and can be discreetly secured under metal, shingles or other roofing surface. The flexible heating element can also be nailed or stapled through, further making installation quick and easy, and is polypropylene fused during fabrication to achieve water proofing and protection from alkaline or salt damage.

Low-voltage heating element

If your system is not powering up as it should after installation, try these simple steps to diagnose the problem.

Remove outer casing of the power pack.

Is the system getting power? (Measure the voltage on the supply side of the power pack.)

Is your snow controller or activation device triggered? (Do you have contact closure across the trigger and 24-volt terminals at the top of the regulator board? This will provide the contact closure for the trigger and 24-volt terminals mentioned above.)

With the casing of the power pack removed, verify that you have power reaching each run of the RoofHeat material:

  1. Check each output’s indicator LED (should be lit when triggered and off when not).
  2. Clamp on the amp probe to one output lead at a time to verify that there is current in each output load. (The amount of power will be determined by the length of the heating material in the circuits and the ambient temperature.) At 70°F the current should be approximately 18.5 amps for a 30-foot run of material.

In addition to designing radiant heat systems, ProLine also provides installation support and free installation training. Contact a ProLine representative today to learn more, at 866.676.9276.

ProLine Radiant Installation Tips

Important Guidelines for Preparing and Installing Radiant Snow and Ice Melting Systems

Although ProLine Radiant offers the industry’s premier radiant heat products and system components, it is important to remember that a radiant heat system is only as good as its installation. That’s why it’s so important to work with a radiant heat provider that offers complete radiant heat services, including professional system design and expert installation support services.

While many radiant heat providers claim to offer installation support, the fact is that most do not have a dedicated support staff of electrical and installation experts. Some unscrupulous businesses can be very persuasive to get consumers to buy, but after the purchase, the customer’s nightmare often begins. When you work with ProLine, you can count on having access to experienced pros to help you through the installation process.

Here are some important tips for installing radiant heat systems:

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.

 ► Check the ohm value shown on the cable tag as soon as you receive the cable. Write the value 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) and then measure the cable’s ohm reading. Record this value in the space provided on the warranty card.
 ► Apply the top layer (concrete, asphalt or pavers) 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. (Keep a cable spacing of at least 2 inches.)
 ► Never cut the heating cable.
 ► In concrete and asphalt applications, the heating cable should be 2 inches from the finished surface. (The heating cable should never be resting on the ground prior to the pour.)
 ► DO NOT 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 heat cable splice by pulling on the cable. Be sure to embed all of the cable, including the entire splice and 6-inches of cold lead.
 ► Do not kink or bend the cable sharply. Doing so can cause the insulation to “bubble” and pull away from the cable.
 ► When installing under pavers, 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.)

ProLine Radiant Floor Heating Solutions

A Wide Variety of Trusted Products

The cooling temperatures are a great incentive to continue to grow your business by installing ProLine radiant heated floors. Loyalty and word of mouth can drive your business, and ProLine products will give you just the reputation you need to continue to build on yours. ProLine floor heating systems are compatible with all standard sub-flooring materials, and offer the premium performance you’d expect from an industry leader. Installation is easy, and once complete, the systems deliver comfortable, even floor heat. And good performance is good for business. (ProLine also offers free installation training.)

Each radiant floor heating job you take on is as unique as the customers you serve. Available on spools or pre-spaced on an adhesive-backed fiberglass mesh, ProLine cable is flexible to meet these demands. Either product can be rolled and cut on site for quick installation, allowing you to tackle challenging, custom-shaped floor-heating projects for your customers with ease.

ProLine floor heating cable can be fitted under just about any flooring surface, and all adjustments of cable spacing (and coverage) can be made onsite. ProLine twin conductor design is matched with premium materials designed to withstand the harshest conditions. It also includes built in ground fault (GFCI) protection and emits no measurable electromagnetic fields (EMF).

ProLine systems also come with a GFCI protected thermostat and strapping to secure and properly space the heating cable. To simplify installation and final hookup, the cable is harnessed with a single lead. And all ProLine cable is UL/CSA approved and is covered by a 10-year manufacturer warranty.

ProLine floor heating mats are simply pre-configured ProLine cable that is pre-spaced in mats for easy installation. They’re compatible with all standard sub-flooring materials, and can be installed directly under tile, natural stone and a variety of hard surfaces. Their low 3/16-inch (3 mm) profile makes these mats great for renovations. They’re also pre-terminated for use with 120V and 240V, and available in various lengths (heating a width of 24-inches).

ProLine thermostats are specifically designed to control electric radiant floor heating systems for maximum comfort and minimum energy consumption. Like spool cable and flooring mats, ProLine thermostats include a Class A GFCI. During conditions that trigger a snow event, an external sensor communicates with the thermostat to turn the cables on or off. Or the thermostat can be configured for control of the floor temperature and regulator without a sensor. The thermostat and GFCI are dual voltage models suitable for 120/240V, 50/60Hz power supplies.

Flexibility and convenience are the hallmark of the ProLine product line. These systems are also matched by outstanding customer support and education available online, and over the phone. ProLine floor heating systems include.
