Stop installation, box out a 3"×3" area surrounding the damaged area and call tech support at (800) 875-5285.
Any trade professional is qualified to layout cables and/or mats; electricians must make the electrical connections and test the wire; you can hire a concrete contractor to install the concrete for you.
The cost for material per square foot is approximately $8.00-15.00 per square foot.
You should install the cable 2-3" below the finished surface, and attach it to rebar and/or reinforcing wire mesh to secure the cable in place.
In-stock items will ship the same day if you place your order before 4:00 PM CST.
The requirements are: 20 watts per square foot foot (with 3" spacing) without a floor covering; or 15 watts per square foot (with 5" spacing of cable only) with a floor covering. To calculate your exact power requirements, multiply the square feet by 20 or 15, as listed above and then divide by the voltage (120V or 240V) to arrive at Amps.
The layers for the full installation are as follows:

The TempZone™ Flex Rolls, Easy Mats and Shower Mats are designed to deliver 15 watts per square foot (maximum allowed by the National Electrical Code), with the heating element positioned 3” apart on a serpentine loop attached to a fiber mesh. The TempZone™ Cable yields between 8-12 watts per square foot, variable, based on the cable spacing. TempZone™ Custom Mats are made to order, so the spacing of the heating element throughout the mat varies according to each specific design. The TempZone™ Custom Mats can yield from 12 to 15 watts per square foot.
TempZone™ is an electric floor heating system that operates like an electric blanket for your floors. TempZone™ is covered in thin-set or Self-Leveling Underlayment, and is installed over the top of your subfloor and beneath your flooring. The system provides a warm, even temperature across your floor, generating floor-to-ceiling radiant warmth to transform these naturally cold surfaces into warm floors. Ideal for kitchens, bathrooms or any room in your home where you would enjoy radiant warmth and comfort, the TempZone™ floor heating system is easy to install, operate and maintain.
The actual cost of operating your floor heating system will vary depending upon a number of factors including the cost of electricity in your area and the length of time you run your system. The WarmlyYours TempZone™ Flex Roll electric floor heating system, for example, uses 15 watts per square foot. Based on a national average electricity rate of $.10/kW/hr, the approximate operating cost of an average bathroom using this system, measuring 8' x 10' would be between $.16 - $.21 cents a day. This cost is based on running your system a full 8 hours per day. Try our Operating Cost Calculator for a quick estimate.
The TempZone™ twin conductor cable present in our TempZone™ products is comprised of a double-insulated, coaxial heating cable. The total thickness of the system can be between ⅛” and 5/32” thick and will not noticeably affect the height of your installed flooring.
No. Never cut the heating cable. The floor heating cable is designed with a very specific resistance in order to consistently maintain heating at the chosen wattage per square foot. Trimming the heating cable would lower the resistance of the cable causing the system to overheat. Adding heating cable to the system would raise the resistance and the system would not heat properly.
Yes. The WarmlyYours TempZone™ floor heating system has withstood rigorous safety testing by the Underwriter's Laboratory and has received UL listing for the U.S. as well cUL certification for Canada. WarmlyYours offers thermostats that carry the CSA Mark and the UL listing, which certifies that the product has been tested under extreme conditions and meets applicable standards for safety and/or performance in the U.S. and Canada. All WarmlyYours thermostats contain a Ground Fault Circuit Interrupter (GFCI) which provides fail-safe protection against an electrical shock.
WarmlyYours’ 25-Year No Nonsense™ Warranty is the most comprehensive warranty in the industry. In the event of a defect, we cover not only the repair or replacement of the TempZone™ system, but ALSO any labor AND materials required to perform the repair.
Please keep in mind that you must check your system with a Digital Ohms meter in conjunction with a Circuit Check™. Take an initial reading as soon as you take the product out of the box to verify that it is within -5% / +10% of the values stated on the product’s label. This will give you a basis of comparison for future readings. Take a second reading once you have positioned the system to match your custom installation plan. It is also advisable to take an additional reading in the middle of the tile installation, just to make sure that the Circuit Check™ is doing its job. Then, take a final reading when you are finished with the floor installation and are ready to hook up the thermostat.
The Circuit Check™ is a tool developed by WarmlyYours to give you peace of mind and ensure trouble-free installations. Simply hook up the cold leads to the tool while you position the system to match your custom installation plan.
The Circuit Check™ will continuously monitor the continuity of the circuit during the installation of your system and during the installation of your flooring. The Circuit Check™ beeps immediately when a short in the system is detected, alerting you to a potentially damaged cable in the area you are working, before you lay the tile over the floor heating system. The WarmlyYours technical support team is available 24/7 to provide assistance if the alarm sounds, or if you would have any questions during your installation.
WarmlyYours nSpiration controls are equipped with an in-floor sensor to precisely control the floor's temperature to comply with the wood manufacturer's temperature recommendation.
The amount of amperage draw depends upon how large the area is that you are heating. For coverage of areas less than 30 square feet, the system will draw less than 3 or 4 amps. If you have a larger area over 120 square feet of heated space, then you may need a larger breaker plus additional controls. No matter what the size of the area you choose to heat, we recommend a dedicated circuit for your system.
While WarmlyYours systems are typically installed by your floor covering contractor, a licensed electrician is recommended for the final thermostat hook-up. With every quote, we provide an Installation Plan layout, together with an electrical plan that has all the info required for the electrician.
These systems work by having an electric heating cable installed underneath the flooring (embedded or floating, depending on the system and floor type), which is then wired to a special thermostat (either one specifically designed for floor heating, like a WarmlyYours’ nSpiration Series control, or a third-party thermostat). When turned on, the heating cable emits heat upward through the flooring which is then radiated throughout the room, heating all solid surfaces.
The answer to this question will depend on a whole host of variables, including, but not limited to, the run time (for supplemental heating, we usually recommend between 4-8 hours per day), the heating system you're using, the total square footage, and your local electrical cost. Typically, the cost is just a few cents a day.
To figure out how much a floor heating system might cost to run for you, make sure to use our interactive Operating Cost Calculator.
The temperature of your floor can range anywhere between 75°F to 95°F. The floor's actual temperature will depend on a number of factors including the amount of heat loss that the room experiences as well as the room’s configuration. For instance, the warmth contained in a two story entry way would likely be less than that of a smaller, more enclosed area such as a bathroom. In a bathroom that is located on the second floor of your home or over another floor in your home that is typically heated, the temperature of your heated floor should easily reach a comfortable temperature of 85 degrees Fahrenheit, if installed correctly. For the heat loss calculation for your specific room, you can access the Heat Loss Calculator or you can call us at (800) 875-5285 and a Customer Service Representative will make the calculation for you.
You can use the Instant Quote Tool, which gives you many options for your floor heating coverage.

The floor heating systems are offered in both 120 volt and 240 volt for the North American market. A 208 volt breaker panel can also accommodate our 240 volt floor heating system. It is important to note that the energy consumption will be the same: a 240 volt system will not cost more to operate than a 120 volt system. You are billed in kilowatts, and the 120 volt and 240 volt systems use the same amount of kilowatts. WarmlyYours often specifies a 120 volt system in smaller projects while a 240 volt system is typically recommended for larger projects (120 square feet of electric floor heating coverage or more). The benefit of switching to a 240 volt system is the reduction in amperage. Our programmable thermostat can control a radiant floor system up to 15 amps. The 120 volt system will reach 15 amps at 120 square feet of electric floor heating coverage. However, the 240 volt system will reach 15 amps at 240 square feet of electric floor heating coverage, allowing a much larger system to be connected to the thermostat. For installations over 240 square feet, a relay contactor or power modules are needed.
WarmlyYours’ TempZone™ product is most commonly installed under tile, stone, and marble flooring, but can also be installed under many other popular floor covering options such as hardwood, vinyl and linoleum. We also have our Environ system, which is an electric floor heating product as well and is specially designed for installation under carpet (in the U.S. only), laminate and floating wood. WarmlyYours can accommodate any flooring type with either of the floor heating products that we offer. If your flooring type isn't listed here, just give us a call at (800) 875-5285 and we will be happy to discuss it with you.
When WarmlyYours floor heating systems are being installed on a concrete slab, we strongly recommend adding a layer of insulation over the slab prior to installing the system. While our systems provide up to 25% more heating power per square foot than many of our competitors, the slab will always act as a "heat sink." Some of the heat that would otherwise be transferred to the flooring surface will remain in the slab, causing the floor’s surface temperature to be considerably lower. This is true with any floor warming system.
When installed on top of a concrete slab without insulation, it is generally accepted that a radiant floor heating system will take the chill away from the floor and provide a small amount of warmth. Adding insulation on top of the slab and beneath any floor heating system will allow a greater percentage of the heat generated to transfer to the flooring surface. This results in greater efficiency and therefore faster warm up times, higher expected surface temperatures and lower energy usage. The floor will have the capacity to warm to a comfortable temperature, and in some cases can be employed as the primary heat source for that room.
The recommended types of insulation are natural cork, insulated tile backer boards and insulated underlayment, such as CeraZorb synthetic cork.
Yes. While there are some systems that can be installed beneath floor joists, most radiant heating systems will need to be installed beneath the floor itself. This is why the best time to install floor heating is during a remodel or as a part of a new construction, when a floor is being installed anyways.
If you're interested in alternative radiant heating methods, check out our Radiant Panels, which are wall-mounted and use infrared technology to provide supplemental heating.
Yes, in most cases, a floor heating system can be effective as a primary heat source. However, our TempZone™ and Environ™ systems are most commonly used as a secondary heat source, providing floor-to-ceiling radiant heat to any room in your home where you desire more warmth and comfort.
If you are considering electric floor heating for an addition to your home, such as a sunroom where you have no other source of heat, WarmlyYours offers an innovative online tool which calculates approximate heat loss. This tool can help you to determine if a WarmlyYours’ floor heating system will provide your desired comfort temperature throughout the year. You can access the Heat Loss Calculator or you can call us at (800) 875-5285 and a Customer Service Representative will make the calculation for you.
Our floor heating systems have withstood rigorous safety testing and earned the UL listing. They produce much less EMF than common household appliances like your TV or vacuum cleaner. The EPRI (Electric Power Research Institute) tests all electrical devices and publishes the data. Many common household appliances are tested at a distance of 6 inches. The test results indicate that on average, the EMF emitted for the following appliances, measured in Milligauss (mG) units, is:
Vacuum Cleaner: 300 mG
Microwave: 200 mG
Portable Heater: 100 mG
Dishwasher: 20 mG
Washing Machine: 20 mG
WarmlyYours TempZone™ (Twin): 1.8 mG
Yes. Unlike the heating cable, the cold lead wires can be trimmed or lengthened with additional lead wire which can be purchased from WarmlyYours.
Hydronic systems operate by using heated water pumped through tubing beneath the floor. Electric underfloor heating works with heated cables beneath the floor. Typically, hydronic systems are a good choice for new construction projects and electric systems are better for remodels or single rooms. This is because the high installation costs of hydronic systems (boilers, pumps, etc.) makes them cost-prohibitive for projects like a bathroom or kitchen.

Typically, electric floor heating is used as a supplemental heat source but in some cases, it can be used as a primary heat source. Electric floor heating is more energy efficient, less prone to spreading dust and allergens, and easier to control from room to room. Air-based heating systems can be used for both heating and cooling and can be a good way to control air quality in the home with regular maintenance.

The roll and mat is 1/16" thick, and the cord is 1/4" in diameter.
No, as long as a licensed electrician properly installs it. We suggest setting your nSpiration Series thermostat control at a maximum of 85°F when the system is installed under laminate flooring. See your laminate manufacturer for their requirements regarding their product when used with electric radiant heat.
The Environ™ Flex Rolls and Easy Mats are designed to deliver 12 watts per square foot.
Multiple Environ™ products may be connected in parallel directly to a thermostat or through the junction box. Please ensure the total amperage of all connected mats doesn’t exceed the thermostat’s maximum load.
The actual cost of operating your floor heating system will vary depending upon a number of factors including the cost of electricity in your area and the length of time you run your system. Try our Operating Cost Calculator for a quick estimate.
The height difference and sound is purely dependent on the choice of carpet and padding. Different carpets and carpet pads have different qualities and will be a determining part of height and sound.
For carpet applications, we require 12" around the perimeter of the room so that a carpet stretcher can be used without damaging the Environ roll or mat. With laminate floors, you can install it wall to wall. We do not recommend heating under heavy pieces (100lb/ft2). And, never heat under permanent fixtures.
No. Laminates that have their pad already attached to the laminate are not compatible with the Environ™ Products.
Environ™ Floor Heating Systems are backed by WarmlyYours 5 and 10 year “No Nonsense™ Warranty* and WarmlyYours highly recognized lifetime 24/7 technical support. Due to the fact that we will also cover not only the cost of labor, but also the cost of the floor itself, our warranty is renowned for being an industry best. Our “No Nonsense™ Warranty” for Environ covers 5 years for under carpet applications and 10 years for under laminate or floating wood floors.
Any type of underlayment/padding may be used as long as it has a density of 6-8 pounds per cubic foot. Certain underlayment, such as ¼” (6mm) thick cork, or 5mm CeraZorb are recommended for Environ™ Flex Rolls. It is also acceptable to place a vapor barrier, such as a plastic sheet, under the underlayment. Underlayment papers are not compatible with Environ™ Flex Rolls. Underlayment is necessary to prevent Environ™ Flex Rolls from damage from the weight of the floor, furniture, and people. Unavoidable wooden floor movements will not harm Environ™ Flex Rolls. Wooden floors expand and contract with temperature and moisture change. The wooden floor “moves” on top of Environ™ Flex Rolls. This movement will not damage Environ™ Flex Rolls when the installation is done correctly and the underside of the final floor covering is installed evenly. Some underlayment materials also have a noise reducing and insulating effect. When installing over concrete, a ¼” underlayment is mandatory. Any underlayment available in ¼” size is acceptable in most cases. CeraZorb, cork, or ¼” to 3/8” of expanded polystyrene (EPS) with a density of 2 pounds per cubic foot or more, are recommended for installation under Environ™ Flex Rolls. When installing over a concrete slab, choose the underlayment with the highest R-Value.
Verify that your laminate is warranted for use with radiant heat. Most modern wood laminate floors are compatible with Environ™ Flex Rolls, but the maximum thickness of the timber / laminate / wooden flooring should not exceed 5/8” (15mm). Flooring that has metallic strips as part of its locking system is NOT compatible, as these metallic strips may damage the Environ™ Flex Rolls. Also laminates that have their pad already attached to the laminate are not compatible with the Environ™ Flex Rolls.
A snow melting system typically costs between $7.00 and $15.00 per square foot, not including a control. Control packages range from $250.00 and $1,500.00 per system.
The electrician may shorten the cold lead wires during the installation. Any lead wire extensions/splices must be made in a junction box in accordance with the installation instructions, and must comply with all national and local electrical codes. Never cut the heating cable.
If a cable is damaged during installation, recheck the system for continuity and confirm the integrity of the insulation with a megohmmeter, or "megger" tester, referring to the installation and testing instructions. If the cable fails any of these tests, take the following actions: clear a 3 foot square working area around the damaged section of cable, and record the cable part number from the UL tag and the location where you purchased the product. Call WarmlyYours with the above information. WarmlyYours will provide further assistance and supply a splice kit suitable for repairing the particular cable.
Each heating cable comes with a factory installed cold lead wire that must be routed through the rigid metal 3/4" conduit to a outdoor rated junction box where a simple wire nut connection can be made for the electrical hook-up.
All of our automatic controllers have a Hold-on time feature after the initial warming up of the snow melt system. This feature ensures that all the snow is melted from the surface, and also that the system continues to operate and evaporate the surface water without it refreezing.
The material costs are similar. However, electric systems are easier to install, with fewer components and significantly lower maintenance costs. Electric systems will run for a shorter period of time to give the same level of performance but with much higher energy efficiency (typically 95%-98% efficient). Controls and sensors required for the two types of systems are very similar. Electric systems do not usually require slab insulation and do not create the concerns typically associated with hydronic systems. These concerns include, but are not limited to, return temperatures, flue gas venting, waterway shrinkage and property damage caused by leaking pipes or tubes.
Never cut the heating cable. A heating cable will not work if it has been cut. If the heating cable is too long, call WarmlyYours to consult with a technician who will guide you in utilizing the additional length of cable.
Never cross, overlap, or allow the heating cables to touch each other. Doing so will quickly cause a circuit failure due to excessive heat build up. Always follow the product instructions and/or design layout plan to ensure the cable is installed with the correct spacing required for proper operation.
Power requirements are measured in Amps and based on three factors: the watts per sq. ft. of the snow melting cable or mat, the area powered and the voltage used for the application. Our product is rated at 50 watts per sq. ft., so that is a constant factor. Most snowmelt projects are powered with 240V AC – not all, but most. The one factor that is always variable is the area to be heated/powered. That is based on your project. For a point of reference, let’s use the example above of a 350 sq. ft. concrete patio.
The formula is (50 W/sq. ft. x area of 350 sq. ft.) / V (240V) = Amps, so 17,500 / 240V = 72.9 Amps
Always confirm the power requirements with the electrician. Large snow melting systems usually require a new electrical panel or electrical service. Contact WarmlyYours for a quotation, indicating the actual power capacity available, and to obtain recommendations for reducing the power consumption. For example, opting for tire track coverage rather than installing the snow melting system over the entire driveway can dramatically reduce power requirements.
Our systems can handle low temperatures, but most controls come equipped with a Low Temperature Lockout Feature. This feature prevents the system from running by default in temperatures below 17F. At temperatures this low it becomes difficult for the system to effectively melt the snow. It is however possible to turn off this feature should you need the system to keep running during such low temperatures.
These systems are designed to melt 1" - 3" of snow per hour on average. Anything above 3" per hour is typically considered blizzard conditions.
To calculate the system's approximate operating costs, multiply the total kilowatts of the system by the cost per kilowatt in your area. Let's use the example of a 350 sq. ft. of concrete patio (residential application), with 240 VAC.
Total Watts: multiply area in sq. ft. x 50 Watts
350 x 50 = 17,500 Total Watts
Kilowatts: (the unit in we purchase electricity) take the Total Watts and divide by 1000
17,500 Total Watts / 1000 = 17.5 Kilowatts.
Kilowatt Rate: use the national average of .12 cents per Kilowatt-hours so how much do we pay for 17.5 kWatts?
17.5 kW x .12 = $2.10 for every full hour of operation.
Hours of Operation: We use a typical 6 hour snowfall for our example.
$2.10 x 6 hours = $12.60 for that snowfall.
All of this will vary due to "after-run time". "After run time" is where the system remains on extra hours after the snow has completed falling, to ensure complete pavement snow melting and drying.
Weights vary based on design but typically range from 9 to 29 pounds. Even larger Towel Warmers will not be a problem when attaching to the wall. As indicated in the instruction manual, you just need to make sure that at least two of the four brackets are attached to a stud.
The Towel Warmer will heat up to between 100 and 140 degrees Fahrenheit. It will not produce sufficient heat to injure you if you touch or brush up against it, though you should still exercise caution around the device. The Towel Warmers have a three to nine inch offset from the wall depending on which model you purrchased; the offset provides sufficient clearance to prevent any damage to the wall. You should also maintain a distance of four inches between the Towel Warmer and surrounding fixtures.
If you are unhappy with your Towel Warmer, please contact WarmlyYours Customer Service at (800) 875-5285 for assistance between the hours of 8:00am and 5:30pm CST, Monday through Friday. Please return your Towel Warmer in the original packaging.
The average cost to operate the Towel Warmer is about fifteen cents per day, though this can vary according to the cost of electricity in your area. The quoted operational cost amount is based on the national average of ten cents per kilowatt hour.
Each Towel Warmer comes with an instruction manual which fully explains how to install the device from start to finish. If you can hang a picture, you can probably install a Towel Warmer. However, you will need a licensed professional who is certified to do electrical wiring for the final hook-up.
The WarmlyYours Towel Warmer is designed for everyday use. The programmable timer can be used to accommodate your lifestyle. If you want to have a warm, dry towel anytime, just program the timer to your desired "on" and "off" times. You can also use the manual function to turn the towel warmer on! There will always be a towel ready for your bath or shower. If you prefer to use the Towel Warmer only occasionally, just bear in mind that the Towel Warmer is designed to gradually warm towels over the course of a day and does work best when towels are left to hang for about 3 hours.
The package includes all the hardware that you will need to install the Towel Warmer. All you will need to provide are the actual tools necessary to install such as a drill and screw driver.
No. The Towel Warmer is not only designed to keep your towels warm and dry but also to withstand the high moisture level in your bathroom.
The Towel Warmer is designed as a stand alone product and will add some warmth to the room. It is, however, the perfect compliment to your floor heating system as they will work together to transform your bathroom into a spa like retreat.
The Towel Warmers are designed to stay on at a relatively constant temperature to keep your bathrobes and towels fresh, warm, and dry. The programmable timer provided with the Towel Warmer allows you to program specific "on" and "off" times. However, should you need to turn the unit off for any reason, the timer features a main on/off switch. The Infinity Towel Warmer is designed with an on/off switch located at the bottom of the left rail (when facing the unit).
Warranty lengths vary depending on the model of the towel warmer, please refer to the Warranty card for more information. If the Towel Warmer is defective or damaged and it was not a result of misuse or misapplication, WarmlyYours will replace the Towel Warmer. The warranty registration card can be accessed from the individual Towel Warmer's Warranty Page and must be completed and submitted online to qualify for warranty coverage.
WarmlyYours Towel Warmers require no more power than is generated from your standard 120V wall outlet. The Towel Warmer is a 'hard wired' device and all wiring is done through the wall. A separate power source is not required; power can be pulled from the nearest available source. The Infinity plug-in model requires that it be plugged into a properly grounded outlet located within 6 feet (1.8m) of the unit.
This heating cable can be used to protect aboveground water pipes, which are insulated and weatherproofed, from freezing—weatherproofing is particularly important for any cable installed outdoors.
No. They are not designed to be powered by DC voltage. They must be used with AC voltage.
There is no built-in thermostat, but we do have recommended WarmlyYours controls which will activate the system for continuous operation at 40°F or below.
We recommend using a fiberglass-based tape, which is available from WarmlyYours.
The amount of cable needed depends on the size and type of pipe, and on the lowest expected temperature. Once you know the type of pipe (metal or plastic), pipe diameter, length of pipe, and the minimum expected temperature, you can use this form to request a quote. Just follow the instructions on the form to get it back to us.
Yes, insulation is highly recommended for use with a pipe freeze protection system for the following reasons:
· It helps cut down on heat loss from the heated water pipe.
· Properly installed insulation helps keep the cable in good contact with the water pipe so that maximum surface area contact is achieved.
· While the cable is wet location approved, weatherproofed insulation adds an extra layer of protection. Ideally, the insulation will be nonflammable and waterproofed.
We sell three different max power outputs: 10W/ft. 8W/ft., and 5W/ft. Because these cables are self-regulating, the actual power output will depend on the temperature (i.e. the lower the temperature, the higher the power output).
Yes. Because the cable is a parallel electrical device, it can be cut to length without affecting its power output per foot. Because we also sell this product by the foot, you can ensure minimal waste on the job-site.
Yes, this depends on the cable type, voltage, and starting temperature. Refer to the Maximum Length vs. Circuit Breaker Size chart found in the manual.
Self-regulating heating cables, like PRO-Tect: Pipe Freeze Protection cables, use a conductive polymer core, which continually adjusts its heat output.
This is why this type of cable, unlike some heat tapes, won’t burn out if it is wrapped closely together, overlapped, or overinsulated. This also means lower operating costs and increased energy efficiency.
At a minimum: a PRO-Tect Pipe Freeze Protection Self-Regulating Cable, an End Seal kit, and a Power Connection Kit. However, we also strongly recommend a control. All of these components are directly available from WarmlyYours (along with other accessories).
Use of another manufacturer’s components will void the warranty.
The Deicing Cable Kit includes a constant wattage heating element that cannot be shortened or altered in any way.
To avoid overheating of the cable, do not operate the cable in warm weather (above 50° F or 10° C).
It is not recommended to install this product to remove ice dams that have already formed or for the purpose of clearing the roof of existing ice and snow.
No, this Deicing Cable Kit is rated for 120V. It should be grounded and ground fault protected in compliance with local electrical codes.
To do the test, uncoil the deicing cable completely so that it does not touch, cross-over or overlap on itself. Do not plug in the cable until it has been completely uncoiled. Plug the cable in, and in approximately 5 minutes, it should feel slightly warm to the touch. Then unplug the cable. Also, a resistance test can be done with a digital multimeter.
Cable length needed depends on the sizes and areas of the roof that need to be deiced (roof with gutter, downspouts, valleys, and/or dormers). Please measure the dimensions of the above areas and see Appendix A of the Installation Manual.
The Deicing Cable Kit doesn't require a thermostat/controller and can be connected to an outlet throughout an entire winter, during a single snow event, or manually when de-icing is needed.
To avoid overheating of the cable, do not allow the heated portion of an operating heating cable to touch or overlap itself or to touch another heating and/or deicing cable.
