Take the Road Less Traveled . . . Install Radiant Heat in the Spring

Even though spring is just waking up, now is a great time to purchase and install a radiant heat system. Early bird discounts may apply to roof deicing systems as well as ProLine heated driveways and snow melting systems.

Installing a heated driveway or snow melting system in early spring puts you at a distinct advantage versus installing it later in the year. As you know, during the summer “construction season”, most contractors are frantically trying to complete as many of their projects as possible before the winter weather hits. Consequently, when fall comes, builders compete to purchase the necessary products to complete their projects. Oftentimes, materials are short, and the pressure to finish the open jobs can be stressful, to say the least. And sometimes it’s difficult for general contractors to find qualified radiant heat installers at the last minute. As successful contractors know, doing the job right, the first time is crucial to those serious about staying in business.

The Advantages of Selling ProLine Radiant Heat and Snow Melting Systems

If the steady snowfall we’ve experienced this season is any indication of future winter events, it’s a great time to offer radiant heat solutions to your customers. Radiant heat is a growing trend among home and business owners for top-down heating and snow removal solutions. Efficient, environmentally friendly and very versatile, ProLine residential and commercial radiant heat systems offer you the chance to expand your offerings and win repeat business.

What makes this trend in heating so attractive to home and business owners alike? As you might expect, radiant heat works exactly as it sounds—it radiates through surfaces (think sidewalks, driveways and wood floors) to warm a specific area of a residence or commercial property quickly and efficiently. ProLine offers several choices for radiant heat systems; the two most common being:

  • Electric radiant heat—uses electric heat cable configured beneath a floor or driveway to warm it up
  • Hydronic radiant heat—relies on hot water delivered through a network of pipes underneath an indoor or outdoor surface to heat it

ProLine radiant heat solutions are designed to deliver consistent, even heat and can be easily configured according to client-specific preferences. Indoors, radiant heat generates a feeling comparable to the warm, enveloping heat of a stove or fireplace. These systems depend largely on heat transfer from one object to another, eliminating the draftiness and duct loss associated with traditional forced air, making them much more efficient.

A switch from forced air to radiant heat also improves air quality within a home, eliminating the constant blowing and belching of air ridden with dirt, dust and allergens that can compromise indoor environments. These clean systems are also very green options in more ways than one. Thermostats can be programmed heat to heat an entire home, or timed to heat specific areas, from kitchen, to living room and bedroom, conserving energy for pennies on the dollar. They’re also flexible enough to install under a variety of surfaces, including wood, laminate, tile and carpet.

Of course this same science works wonders outside to keep snow and ice away from residences and commercial properties. ProLine offers several easily-configurable options, from electric cable right off the spool, to preconfigured mats or RauPanels (hydronic systems), depending on client preferences and overall needs. Electric cable, for example, is great for smaller, hard to reach or unusually shaped areas, while the demands of a larger commercial footprint may be better served with hydronics because of the possibility of lower operating costs. Either way, these applications mitigate risk by keeping pavement clear and dry, before snow and ice can accumulate. And they’re equally effective under brick pavers and stone as well as concrete and asphalt pours or overlays.

Fortunately, whatever client demands come your way, ProLine offers radiant heat professionals on-demand installation services, and an extensive inventory of products to match every job. We can walk you through a project from conception to completion. When you do business with ProLine, you’ll appreciate not only access to the pros, but free installation training and our vast library of materials, including articles and schematics to help you along the way.

Snow Melting System Pre-installation Checklist

What NOT to do When Installing Radiant Heat – Tips and Advice from the Pros

Radiant heat is a proven technology that produces impressive results. But like most products, if the system components aren’t installed correctly, the radiant heat system can’t perform as intended, and the customer is left frustrated and disappointed. Despite the advanced technology involved, installing a radiant heat system is not difficult, but there are some key guidelines to follow to ensure that the system performs as intended. While consumers can buy the best snow melting system components from ProLine Radiant, unless they’re installed correctly the system won’t produce the results you’re expecting.

ProLine is a proven and trusted wholesale radiant heat provider offering snow melting, roof deicing, pipe trace and floor heating solutions. But ProLine isn’t content to simply carry the industry’s premier radiant heat products. ProLine has broken away from the pack by offering and following through with the best customer service in the industry.

ProLine Radiant has built its success upon the industry’s most preeminent customer services. Because proper installation of radiant heat systems is vital, ProLine not only includes installation support services, but offers free installation training courses. Installers can attend via WebX or in person at ProLine’s headquarters. Complete system layout and design AutoCADs with specs are also available, so customers will know proper layout and materials, load calculations, breaker sizes, number of breakers, and other technical aspects of the installation prior to any heat cable being installed. It’s this attention to quality customer service that distinguishes ProLine from the competition, and helps to ensure that each system installed performs as intended.

In addition to the personal service and support, ProLine continually posts information and tips for installing radiant heat systems. Top quality products are only part of the complete radiant heat solution. “Our product line has proven itself,” stated Brandon Weaver, Director of National Sales for ProLine. “But it’s vital that installers follow a few simple guidelines to install these systems correctly, so that customers can enjoy the full benefit of our premier products. It’s helpful to read the information we post online, and never hesitate to call our tech support team if you have questions during the installation.”

Some of the most common installation mistakes include:

  1. IMPROPER CABLE SPACING. Take the time necessary to layout and then inspect the heat cable to ensure that it’s spaced properly. Follow the basic cable spacing rules: Keep the cable at a minimum spacing of 2 inches and a maximum of 4 inches (center-to-center).
  2. IMPROPER CABLE DEPTH. Don’t let the heat cable rest on the ground before a concrete pour. Use Mesh-Ups to elevate the cable so that it remains in the center of the slab with the remesh. (Mesh-Ups are plastic support ‘chairs’ that are valuable, yet extremely affordable and they can make all the difference in the world between a successful and an unsuccessful installation.) Mesh-Ups keep the heat cable that is secured to the remesh elevated from resting on the ground as the concrete is poured. It’s a simple, affordable solution to keep the heat cable at the ideal distance from the concrete’s surface, thereby resulting in optimum snow melting performance.
  3. NEGLECTED WARRANTY CARD. Too many installers neglect to fill out the warranty card and mail it to the manufacturer. Don’t let this happen.
  4. FORGETTING TO TEST THE CABLE. Do not forget to test the cable during all phases of the installation. Start by testing the cable out of the box and then throughout each aspect of the installation.
  5. COMPROMISED HEAT CABLE. Never cut or damage the heat cable. If you must use steel rakes and shovels, take extreme caution when using these tools during the concrete pour to avoid damaging the heat cable.

One way to limit mistakes during an installation is not only to avoid the above errors, but to follow the handy checklist below:

Pre-installation Checklist

Before buying and installing a radiant heat system, review the checklist below.

  • Verify the correct voltage of the home or business where the system is being installed (220/240 or 110/120).
  • Verify the available amperage. Do not guess or assume. Because of the importance of this information, we recommend having an electrician come to your location to measure the amperage.
  • Hire a trusted electrician, preferably one you’ve worked with before. Let’s face it, not everyone is competent or ethical, so find one who has been in business for several years. Ask around and talk with those who have personal experience with electricians.
  • Keep in mind that the National Electric Code (NEC) requires that the system has 30mA GFEP (30mA trip protection).

After installing your radiant heat system, fill out and mail your warranty card.

Perhaps the most overlooked tip – and one that can eliminate installation mistakes and unhappy customers – is to take advantage of the free training! Call 801.948.7577 or 866.676.9276 to sign up or learn more.

Installation Tips – Installing a Heated Paver Driveway

Installing a Snowmelt System under Pavers

Always check the element resistance and the insulation resistance of the heating cable upon receipt and during the installation:

  1. Upon receipt: Test the cables out of the box and write the values on the warranty card.
  2. Test the cables after laying them out over the area to be heated. Write the values on the warranty card.
  3. Test the cables after the embedment. Write the values on the warranty card.
  4. Record your readings in the installation manual.

Heating cable installed for heated paver driveway

Prior to laying out the heat cable, lay down thin wire mesh over 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. The mesh is used to secure the cable and help ensure proper cable spacing.

Begin the cable installation as close as possible to the contactor panel / electrical source.

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 while applying the paver sand and pavers.

DO NOT cut or alter the heating cable. The white binding tape of the heating mats may be cut in order to make turns with the mats, but the heat cable must never be cut or altered.

Maintain proper cable spacing
Heating cable being properly spaced and secured to remesh prior to a concrete pour.

When laying out the cable, DO NOT allow the heating cables to touch, cross, overlap or get bunched up. The cable must maintain a minimum spacing of 2 inches and a maximum of 4 inches.

The minimum spacing for the heating cable is no less than 2-inches center-to-center and no more than 4-inches center-to-center. Make sure cable from adjacent mats also follows the proper spacing guidelines. After securing the heat cable, double check the spacing one last time before adding the top surface of paver sand or dust.

Check with the paver or block manufacturer to determine the proper depth of sand or dust needed for ideal paver installation.

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 dust or sand. (This may vary depending on the pavers used. Make sure you follow the manufacturer’s guidelines for proper embedment depth.) The cable and splice to the cold lead must be completely embedded. Make sure there are no air gaps around the cable or splice. IMPORTANT NOTE: The gauge of the paver sand, stone dust or base material must be fine enough to completely encapsulate the cable.

Be careful handling the pavers after the cable is laid out. Do NOT drop a brick or stone paver directly on the cable. This can damage the insulation and cause the cable to fail. If a paver is dropped onto a cable, immediately stop the installation and check the integrity of the cable with an ohm reading.

Handle the heating cables carefully. Exercise caution when using tools such as shovels, rakes and wheel barrels so that you do not damage the cables.

Consistently verify the cable integrity by checking the resistance during various stages of the installation.

Heated paver driveway

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 ProLine BEFORE installing.

* This list is intended as a general quick reference guide. It is NOT a substitution for proper training and following the installation manual. Always read and follow the installation manual. Web-based training is available on request.

The Many Responsibilities of General Contractors

Helping to Ease the Load for General Contractors

The duties and responsibilities of a general contractor (GC) are enormous, to say the least. The necessary expertise includes reviewing and producing project-specific documents and architectural drawings as well as hands-on construction and project management skills. The GC is responsible for all aspects of a construction project and coordinates all the facets of a wide range of commercial and residential construction projects.

After reviewing upcoming projects, the GC begins the complex process of preparing the proposal and other necessary documents for the client while determining the material needs and hiring the appropriate subcontractors to successfully complete specialized aspects of the project in the time frame provided.

The success of the contractor’s business is dependent on acquiring the building materials that best meet the quality demands and client’s budget criteria as well as hiring competent subcontractors who have proven to deliver quality work in a timely manner. It is the general contractor who is ultimately responsible for every aspect of a construction project, so teaming up with the right material suppliers and subcontractors is vital to the success of the project, the satisfaction of the customer, and reputation of the contractor.

Finding the right suppliers and subcontractors can be a time consuming venture, so most contractors stick to using those whom they’ve worked with before and have proven track records. Still, the most successful contractors always keep an eye open for better prices, workmanship and turnaround.

In the construction industry, word of mouth carries a lot weight, and many contractors benefit by asking other building professionals about their experiences with suppliers or subcontractors. Looking for ways to continually improve one’s business is the hallmark of successful companies. In today’s competitive market, the businesses that survive – and flourish – are those that explore options and consistently seek to optimize efficiency or save money and time without sacrificing quality. And most builders agree that the most effective way to explore options is through word of mouth recommendations.

While most contractors utilize familiar subcontractors for the standard construction needs of a project (framing, roofing, plumbing, etc.), the “less-routine” aspects of some construction jobs require expertise in which some GCs are less familiar. For example, not all contractors are experienced with radiant heat installations, so finding a proven supplier of radiant heat products may pose some unique challenges. As simple as it may sound to find a provider of radiant heat products, the discrepancies between companies can be dramatic, and oftentimes those discrepancies are not discovered until after the contract is signed, or after installation. And who takes the heat for an installation gone wrong?  The general contractor. Fortunately however, there are some telling indicators when it comes to comparing radiant heat companies, and it is this set of indicators that contractors should familiarize themselves with. In addition to word of mouth, use these criteria when evaluating various radiant heat providers.

Installation Support Services by a Dedicated Staff of Technical Experts – Many companies tout their technical services, when in fact, if installers are fortunate enough to talk to someone for technical support during the installation process, they’re likely speaking with a salesperson and not an electrical expert or seasoned installation professional.

ProLine backs up its products with a dedicated support staff. These technical experts understand all the layout and electrical aspects of a radiant heat installation and will take the time necessary to walk you through any issues you may have during the installation.

Detailed System Design and Layout – The top radiant heat companies provide customers with comprehensive system design drawings. These professional layouts are computer assisted drawings (CADs) that should contain a detailed layout of the heat cable, cold lead and contactor panel. The document should also identify the proper layout and materials, load calculations, breaker sizes, and number of breakers. Essentially, all the technical specs and installation information should be contained in the document. When working with an industry leader, customers will understand how the automated system works and how it is expected to perform prior to any installation taking place.

Wide Selection of Products – Check the product lines to make sure that products are available from more than just one manufacturer. You want to be able to select the best solution for your specific radiant heat needs.

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.
