Installation Tips – Installing a Snow Melting System in Concrete

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

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

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

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

Placing Mesh-Ups under cable and remesh

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

* These tips are meant for quick reference. 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.

Installation Tips – Installing a Snow Melting System Under Pavers

Installing Heat Cable under Pavers (Quick Reference Guide – Article 3 in a Series of 3)

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

  1. In the box: Write the values on the warranty card.
  2. After being laid out: Write the values on the warranty card.
  3. After being covered: Write the values on the warranty card.
  4. Record your readings in the installation manual.

When laying out the cable, DO NOT allow heating cables to touch, cross, overlap or get bunched up. Minimum allowable spacing is 2 inches.

Begin installation as close as possible to the electrical source.

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

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

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

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

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

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

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

Verify cable integrity by checking resistance often during installation.

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

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

* 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 Benefits and Custom Options of Heated Driveways and Snow Melting Systems

Radiant Heat Can be Tailored to Your Specific Needs and Budget

Heated driveway systems are surefire ways to enhance safety for businesses located in cold weather climates. From grocery stores to restaurants and car washes, business owners are turning to radiant heat to ensure safety and protect themselves from liability claims.

Warmzone radiant heat systems are fully automated, so there’s no need for business owners to show up at the workplace early to shovel snow. The automated systems activate when an aerial or ground-mount snow sensor detects precipitation and temperatures are below a set point (typically 39°F). The energy efficient snow melting systems operate only when needed, and are also maintenance free – another favorite feature among business owners.

Easy to Customize

Radiant snow melting systems are easy to customize. Electric snowmelt systems can be installed to heat unique shapes and areas, and can be tailored to best meet the client’s budget needs. In addition to heating entire driveways and sidewalks, some other popular layout options for heating driveways include:

Heating tire tracks: Rather than heating an entire driveway, install two 24-inch wide heated tire tracks.

Heated driveway with two heated tire tracks

Heating the Center Strip or High Traffic Areas: Heat only an 8 or 10-foot wide strip up the middle of the driveway. Or install heat cable only in the most trafficked area of your driveway. Heat trouble spots such as inclines or where shade often causes ice buildup. Instead of heating an entire sidewalk, just warm a 3-foot wide strip in the middle; or heat the steps and heavily trafficked areas of entry points and porches. Businesses often install radiant heat to melt snow and ice in parking areas and walkways near the store front as well as in loading docks and ramps.

Custom heated driveways and sidewalks

Heating specific/custom areas: Many consumers install radiant heat only for specific needs. For example, heat dog runs or kennels to keep outdoor pets comfortable, or only heat the sloped areas of a sidewalk or just the steps. The options are virtually limitless when it comes to installing heated driveways.

Power Requirements and Operating Costs of a Heated Driveway

Understanding the Power Requirements for a Heated Driveway

Are you looking to install a radiant heated driveway for your home or business? If so, one of the first questions you need to answer 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, customers must ensure that they do meet the power requirements for heating their driveways and or walks.

So, just how does one go about determining the power requirements for heating a specific area and how does one know whether the necessary power is available? First of all, you don’t have to figure this out by yourself. Warmzone’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 your specific snow melting and budget needs.

But homeowners should be aware of some basic guidelines when shopping for radiant heat. For example, 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.) But the bottom line, in terms of power requirements, is that an electrician is ultimately the one to address all power issues. If you have questions about available power, talk with Warmzone as well as a qualified electrician to make certain there are no issues should you choose to move forward with the installation.

If you’re unsure of the square footage of your driveway, no worries; Warmzone can calculate that for you too. In most areas, using a special state-of-the-art technology, Warmzone 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.

Zoning Your Driveway Heating System

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. Click here for more detailed information about zoning your heated driveway.

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. (The average American home has an 800 square foot driveway.)
  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 kilowatts by the kilowatt rate. This gives you the cost-per-hour of usage for the snow melting system.

EXAMPLE for heating an 800 square foot driveway:
800 (sq.ft.) 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 you 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.

The operating cost of an automated snow melting system is typically less than that of hiring a professional snow removal service. And radiant heat 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. Safety is particularly important for business owners who wish to avoid costly litigation due to personal injuries caused by slick ice.

Timing is Everything

Don’t get Caught Holding the Shovel next Winter — Install a Radiant Snow Melting System and Beat the Rush!

With summer just around the corner, it’s a good time to spring for a new radiant heated driveway or walkway. Buying and installing your radiant heated snow melting system early in the summer puts you at a distinct advantage. In the fall, contractors generally rush to get their projects done before winter, and their availability is limited. Hiring someone now could save you the heartache of putting off that heated driveway or walkway project for another season. Shopping contractors before the fall rush also allows you to take your time interviewing and selecting a professional.

Whether you’re pouring a new concrete or repairing existing pavement, radiant heat installation is an excellent way to enhance, preserve and protect your driveway or walkway from harsh snow melting chemicals or damage from snow removal equipment. It’s a smart home investment that not only preserves and protects your property, but can also prevent slip and fall accidents, as well as injury from shoveling. Snow melting systems can also save you the time, and over time, the added expense of hiring a contractor to plow your driveway. With radiant heated driveways and walkways, you get “on-demand” snow removal, and the opportunity to experience dry pavement all year round. And the systems operate silently on renewable energy and are fully automated.

Heated paver driveway

As you shop, be leery of the contractor who offers limited solutions that come with a high price tag. Radiant heat applications are extremely flexible and adaptable, offering homeowners many options to achieve their goals. You don’t have to tear up your entire driveway to enjoy the benefits of radiant heat. Rolling out pre-configured mats on top of an asphalt driveway and applying a new layer of asphalt over the cable, or cutting grooves in concrete for the heat cable (which are then filled with an epoxy) are just some of the ways to get around a new heated driveway installation.

To help you sort out your options you may also want to consider contacting Warmzone for a free snow melting system estimate. They have the knowledge and the know-how to put together a snow melting solution that will meet or even beat your performance and budgetary requirements.  Partnering with professional installers across the country, Warmzone works diligently to come up with solutions for the most discriminating customers. As they say, knowledge is power, and getting initial estimates from Warmzone before you shop can help you identify all of your options, and the right person for the job, to avoid the “sticker shock” that comes with choosing the wrong one. And remember, a radiant heat system is only as good as its installation, and Warmzone can recommend experienced, reputable installers in your area.

Among the many home improvement projects on your to-do list, a radiant heated snow melting system is the gift that just keeps on giving from the moment you see that first snowflake fall. Winter may seem a long way off, but the window for hiring a contractor to install your snow melting system is small. Whether you lack the motivation or need more information, it’s always a good idea to give Warmzone a call at 888.488.9276 for free professional advice and support.
