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.

An Easy, Affordable Solution for Ground Fault Protection Requirements

Warmzone Continues to Listen to Contractors and Serve the Needs of Homeowners

Electric snow melting, roof deicing and outdoor pipe heating systems installed in the United States and Canada require ground fault protection for safe operation. In many cases, when installing a snow melting system, these breakers can be expensive and difficult to find. However, thanks to Warmzone, this is no longer an issue.

In addition to offering contactor panels with ground fault protection, Warmzone also offers separate ground fault protection units with snow melting systems and activation devices. These units provide an inexpensive, easy-to-integrate solution to meet the NEC requirements for ground fault protection equipment.

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, Warmzone’s GF unit maintains a 30mA fault trip point to reduce nuisance tripping. The unit’s unique design allows installation of standard, off-the-shelf overload breakers into the customer load center. Size the breaker and wiring for the system (15A to 60A), 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 unit is housed in a rugged, NEMA 4X/IP65 rated enclosure, suitable for indoor or outdoor installation. The enclosure features a gasket-sealed front access door for easy testing and reset. All internal electronic components are specified for -40°C to +60°C operation. The enclosure can be easily surface mounted near the load center or near the snow melting system, depending on the installer’s preference. Numerous knockout locations on the enclosure provide flexibility for installation and wiring. The enclosure base can accommodate standard ½ and ¾-inch conduit hubs. Four mounting holes outside the enclosure gasket make mounting a breeze while assuring weather-tight performance.

Ground fault protection unit enclosure
Enclosure for ground fault protection equipment

Features

  • Easy installation; convenient access for wiring
  • Works together 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
  • Latching, sealed, hinged front cover for easy testing and reset access
  • No overload rating means just 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 Warmzone’s WS-2C, WS-5C and WS-8C aerial mount snow sensors. They can also be used with 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 the requirement of identifying the customer’s load center type or need to research if a combined overload/GFPE breaker is available and how long it will take to receive.

Including a GF unit completes the snow melting system and makes it 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.

Finding the Right Roof Heating System

Keeping your roof free and clear of ice and snow comes down to proven radiant heating elements, proper system design, and proper installation. A good radiant heat solution is one that addresses all of the potential problem areas of your roof.  Warmzone offers a variety of roof heating solutions designed to not only melt snow and ice, but to keep the runoff flowing from your roof before it has a chance to freeze. Warmzone products are specifically designed to target all aspects of a roof, including gutters, downspouts, roof lines, roof eaves and edges—the places icicles, ice dams, and snow build-up are most likely to occur. To keep your roof free of ice and snow, it’s important to target the typical problem spots.

Heating Gutters, Edges and Problem Areas

Warmzone self-regulating heat cable is an extremely effective and energy efficient way to prevent ice dams and keep water flowing through gutters and downspouts. Comprised of a rugged, durable outer construction and an irradiated conductive core that responds to variations in temperature, this durable cable is the affordable choice for heating problem areas of your roof.

Heating Roof Edges

The single greatest snow and ice problem for roofs is due to ice dams. Snow and ice buildup occurs when runoff reaches the colder roof eaves and refreezes. Over time, the buildup increases, resulting in large dams of ice near the roof’s edge, causing water to pool behind it. As that water seeps under the shingles and refreezes, damage can occur, and may eventually lead to costly water damage inside the home.

Low-voltage roof heating element

Low-voltage RoofHeat STEP systems can be installed discreetly under the shingles to keep roof edges completely free of snow and ice. This advanced system utilizes a thin, semi-conductive polymer heating element that can be nailed or stapled through to make installation quick and easy. The self-regulating heating element is polypropylene fused during fabrication to achieve water proofing and protection from alkaline or salt damage.

Attractive roof deicing panels can also be installed to eliminate the possibility of ice dams. Available in a variety of sizes, these aluminum panels feature channels of self-regulating heat cable that effectively heats the aluminum to keep roof edges free of snow and ice. The panels have an attractive Kynar finish and can be used in new construction and on existing roofs with most types of roofing materials, including asphalt, wood shake shingles, tile, slate or standing seam metal. Visit our roof deicing panel documents page to learn more.

Heating Roof Valleys

Four and six-inch RoofHeat deicing panels are also available to heat roof valleys. Keeping these channels free of snow and ice facilitates runoff and helps to protect your roof by eliminating potential trouble spots. The Valley Panel system will create an open area (up to 10 inches) for water to safely flow from the roof through the valleys without the possibility of water refreezing over unheated portions of the roof. The Valley Panel roof heating system provides an aesthetic look to any structure while keeping a more efficient and cleaner method of eliminating ice dam issues in a valley or dormer.

Eliminating Icicles

For areas of your roof where gutters are not present heated roof edges can be used to channel water away from the structure. Heated Drip Edge systems are extremely effective in battling icicle build-up while maintaining the aesthetic look of the original roof. This is a common, reliable solution for businesses to ensure the safety and convenience of pedestrian traffic. These Kylar-finished edge lines are offered in a wide variety of materials, including steel, copper, aluminum and more, so they’re great for concealing wiring along the drip line to create a more attractive, polished appearance.  An existing metal roof can also be retrofitted with roof heating panels, which can be laid on top of the old metal roof, in direct contact with the self-regulating heat cable to prevent icicle formation.

Still not sure what you need for your roof? Our radiant heat experts work with customers to evaluate project challenges and determine an affordable roof deicing system that is best for your unique circumstances. Warmzone roof heating experts are also available to walk you through the process, from system selection to installation. Call 888.488.9276 for more information today.

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?

Snow melting system overview

Click image to enlarge.

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.

Mesh-Ups under remesh, supporting heat cable

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.

View additional “How to” Videos from Warmzone.

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

The Versatility of Snow Melting Systems

The Versatility of Radiant Snow melting Systems

Because of the reliability and versatility of radiant heat snow melting systems, these solutions are proving to be popular home improvement and new construction projects. And because radiant heat systems are so easy to customize, homeowners can flex their creative muscles when it comes to installing these systems.

Warmzone radiant heat systems are easily configurable to use in a variety of applications, whether you want to heat an entire driveway, tire tracks, steps, sidewalk or porch, etc. The cables can also be installed under a variety of mediums, such as brick/stone pavers, concrete and asphalt, providing you with endless possibilities when it comes to enhancing your home’s curb appeal.  Whatever your goals and budget, you’ll find a range of versatile, affordable radiant snow melting systems flexible enough to conform to your specific needs.

Snow melting heat cable laid out for asphalt heated driveway.

One of the most popular, affordable, and easy to install applications for radiant heat is asphalt. Where asphalt gives and flexes according to a wide-range of seasonal temperature changes, the specially designed Warmzone heat cable ensures consistent, effective performance to keep driveways clear of snow and ice in all the conditions. Designed specifically for installation in hot asphalt applications, ClearZone heat cable is rated up to 460 degrees for up to 10 minutes. For additional technical specs and installation information, please refer to the ClearZone installation manual.

ClearZone 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 placed on the existing asphalt and new asphalt is then applied on top. A compacted layer of 2 inches is recommended. Refer to the installation manual for compacting instructions. (In addition to the benefits of heating asphalt applications, snow melting systems can also prolong the life of concrete driveways and pavers as well.)

If you’re seriously considering heating an asphalt driveway or ramp, be sure to take advantage of Warmzone’s unparalleled customer services, including free installation training, installation support, system design and layout, and online installation tips and guides.

A Few Helpful Installation Tips:

  • Heating cables should never touch, cross, overlap or get bunched up. A minimum cable spacing of 2 inches is required.
  • Check the maximum rated heat temperature of the heating cables before you apply hot asphalt. The asphalt must not exceed this temperature.
  • Pouring small quantities of asphalt on the heating cables helps to ensure a safe installation and prevent damage to the cables.
  • Never cut or alter heating cable. To accommodate your layout needs, cut the tape backing of the cable mats, but do not cut the heat cable.
  • Manually lay the asphalt, and be sure to spread it evenly around and over the heating cables.
  • 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, lay down sheets of plywood over the cable to avoid damaging the cable’s outer jacket.
  • Use a Megger to consistently check the cable resistance during installation.

Among construction professionals, one of the most valued Warmzone services is the free installation training. Installers can attend courses in person or online via WebEx. In many cases, installers can even arrange to have an instructor provide training on location or supervise the installation in person. After successfully finishing the course, installers receive a certificate of completion. Warmzone can then refer future projects to the “certified” installer as other installation opportunities arise in the area.

Knowing that the proper installation of a radiant heat system is crucial to its success, Warmzone also offers a comprehensive online resource of “how-to” videos on its website. Being able to see the procedures and proper installation techniques in videos has proven to be extremely valuable to contractors and installers. Warmzone strives to make the installation process as seamless as possible for professional builders, and continues to produce informative videos for its popular “Warmzone University” online training and video section.

General Tips for Using the ETO2 Controller for Snow Melting Systems

Introduction

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.)
