Frequently Asked Questions

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 significantly less EMF than common household appliances like your TV or vacuum cleaner. For more information on the subject, please view our EMF Frequently Asked Questions.

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 SmartStat™ is equipped with an in-floor sensor to precisely control the floor's temperature to comply with the wood manufacturer's temperature recommendation. For more information, please visit our floor heating under hardwood page, where you will find detailed information and industry research performed by WarmlyYours and Launstein about heated hardwood floors.
Yes. Unlike the heating cable, the cold lead wires can be trimmed or lengthened with additional lead wire which can be purchased from WarmlyYours.
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.
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.
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.
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.
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.

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.

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.
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.
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 Energy Use Calculator for a quick estimate.
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.
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.
The roll and mat is 1/16" thick, and the cord is 1/4" in diameter.
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.
No, as long as a licensed electrician properly installs it. We suggest setting the SmartStat™ or EasyStat™ thermostat control at a maximum of 85°F when it is installed under laminate flooring. See your laminate manufacturer for their requirements regarding their product when used with electric radiant heat.
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.
The Environ™ Flex Rolls and Easy Mats are designed to deliver 12 watts per square foot.
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 Energy Use Calculator for a quick estimate.
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.
The cost for material per square foot is approximately $8.00-15.00 per square foot.
The layers for the full installation are as follows:
  • Bottom: 8-10" of compressed crushed rock aggregate (may already exist)
  • 4-12” layer of sand (may already exist)
  • 2" polystyrene insulation
  • 2-3" layer of concrete
  • Rebar and/or reinforcing mesh and attach the cable or mat
  • Top: Pour a 2-3" layer of concrete as the final flooring surface
Call tech support at (800) 875-5285 to customize this to your unique application.
You can control your slab heating system with a thermostat, our SmartStat™ or EasyStat™, and you may also need to add a relay and/or power module.
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.

In-stock items will ship the same day if you place your order before 4:00 PM CST.
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.
Electromagnetic Fields (EMF) are part of our everyday life and are present in such things such as power lines, home wiring, televisions, computer screens, microwave ovens, cell phones, and other common electrical devices. These invisible lines of force are generated by the presence of electric charges and surround any electrical wire or device. They consist of two related components - the electric field, which is the result of voltage, and the magnetic field, which is the result of current flow. Typically, an electromagnetic field is considered to be that space limited to a local area around an object. The strength of the field decreases rapidly with distance from the source.
Electromagnetic fields are measured in Gauss (G) which is the standard unit of measurement for electromagnetic flux – the strength of an electromagnetic field. Often times, the EMF emitted from an object is much less than a Gauss. This lesser unit of measure is referred to as a Milligauss (mG) which is the equivalent of 1/1000th of a Gauss.
While some debate still exists over the heath hazards associated with residential exposure, the prevailing opinion of the scientific community, to include the National Research Council and the National Institute of Health, is that there is no strong evidence that exposure to EMF poses any significant health risk.

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 is:

Vacuum Cleaners 300mG
Microwave Ovens 200mG
Portable Heater 100mG
Dishwashers 20mG
Washing Machine 20mG
Electric Dryer 3mG
WarmlyYours TempZone™ 1.8mG

The TempZone™ Twin heating cable has shown compliance with the requirements in EN50366:2003 + Amendment 1:2006, as tested by Intertek ETL Semko, a Nationally Recognized Testing Laboratory. Report number 815973/M1. The tested value is extremely low at 0.5% of the allowed value.

EMF testing protocol is an international value, as there is no test protocol for the United States. This is a European Standard that deals with electromagnetic fields and defines methods for evaluating the electric field and the magnetic field for frequencies up to 300 GHz around household and similar electrical appliances.

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.
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.
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.
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.
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.

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.

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.
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.
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 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).
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.
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.
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.
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.
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 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.
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.
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.
