How Warm Are Heated Floor Systems?

Most wood flooring manufacturers recommend that the heated wood floor temperature be maintained between 80 to 85 degrees. This provides a warmer surface than an unheated floor, even in a well-heated house, but it is not so warm that it would feel hot to the touch.

The warmth of the floor is also dependent on the characteristics of the selected wood flooring. A thinner floor will typically be a few degrees warmer than a floor with thicker boards. Some wood species offer slightly better performance for radiant heating than others. The way that the boards are sawn can also make a difference. Quarter sawn boards are more expensive, but are more stable and less prone to swelling and shrinkage due to humidity changes. It has also been noted that darker woods will be less likely to show gaps and cracks. All of these factors should be considered in choosing the hardwood floor for your home.

Radiant heat has higher levels of energy efficiency than most traditional systems.

Frequently Asked Questions


Can I have one thermostat for my open floor kitchen, dining room and living room?

We usually recommend that you have an individual thermostat for each room. However, if it's an open floor plan and your local electrical code allows you to have one controller for the whole area, then it's definitely possible to have it all controlled from one thermostat.

Can I heat luxury vinyl tile/planks in the kitchen?

Yes, our TempZone Heating Products can be used for heating luxury vinyl tile or luxury vinyl planks in any indoor application.

Can I put electric floor heating in the shower?

Yes, we have TempZone Shower and Bench mats with sizes designed specifically for shower installation and they are wet location listed for for installing electric radiant floor heating to a shower.

Can I put furniture on top of underfloor heating?

Yes, but any furniture that may trap heat, such as pieces with an enclosed bottom, should be avoided. Furniture on legs with a clearance of at least 3" is permissible.

Can I use electric floor heating as a primary heat source?

Yes, in most cases, an electric 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’ electric radiant 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.

Can I use the floor heat with LVT?

Yes, we recommend using the Tempzone system encased in ⅜“-½“ of self-leveling cement followed by LVT.

Can the floor be waterproofed and still have floor heating?

Yes, we offer several options to help make your floor heating system water resistant or waterproof. Our TempZone product line is designed for wet areas - making it completely safe for rooms that will have water on the floor at times or may experience leaks or flooding. We also offer waterproofing bands for our TempZone Cable + Prodeso Uncoupling Membrane system. Allowing you to waterproof all seams and the perimeters of the wall - guaranteeing that your floor heating system stays safe and prevents water from leaking to areas below.

Can the floor heating be set to turn on at certain times when we know we will use those areas and need heating?

Yes, with our programmable thermostats, you can choose which days and times the floor heating turns on for your comfort. With a Smart thermostat, you can also control these options from your phone while away from home.

Can the heating wire be shortened?

It cannot be shortened, all heating cable must be used at appropriate spacing.

Can this be tied in with the floor heating in the rest of the room or will they need to be on separate thermostats?

The shower floor heating kits can be tied into floor heating for the rest of the bathroom - allowing for one thermostat to control both areas as long as both areas are using less than 15 amps. When designing installation plans, we design with only one thermostat by default. If you prefer two separate thermostats, it might be a good idea, since the shower floor application is usually thicker and takes longer to heat. Be sure to let us know when discussing your quote with our team.

Can this floor heating be used on existing hardwood floors?

No, most in-floor heating is designed to be added to new flooring. If you do have existing wood floors you would like to add radiant heating to - it is possible to do so with an under-joist heating system. An example of this type of system can be found here: https://www.warmfloor.com/floor-heating/products-and-applications/step-joists/

Can this heating system be installed over Solid Polymer Core (SPC) floor or a Wood Plastic Composite (WPC) Luxury Vinyl Tile (LVT) floor?

We suggest removing SPC or WPC flooring before installing the floor heating system over it if possible. If that is not practical, use an underlayment designed specifically for covering these types of floors. Radiant heating can be used with many types of these floors, but check with the flooring manufacturer to confirm that it can be paired with these types of systems.

Can you heat under the appliances, fixtures, or furniture in a laundry room, mudroom, or utility room?

No, it is recommended that floor heating only be installed in the areas that you will walk on. Heat can become trapped if installed under objects that do not offer enough clearance for air to circulate (such as a washer or dryer).

Can you install a floor heating system in a shower?

Yes, our TempZone™ Shower Floor Mats are designed and listed for installation in wet locations under tile and stone.

Can you use a sunroom in the winter?

Yes, sunrooms can be used in the winter, just activate your floor heating or radiant panel and turn your sunroom into a 4-season room. You will notice a tremendous difference in the room comfort, especially with the thermostat set to maintain a desired ambient temperature. WarmlyYours thermostats will do the work for you by energizing the floor for longer cycles.

Can you use glue-down Luxury Vinyl Tile products with this floor heating system?

Yes, if the flooring manufacturer recommends this installation method. In most cases, the heating element will still need to be embedded in self-leveling cement before the flooring is installed.

Does the heat cause any shrinkage, expansion, or warping of the vinyl flooring?

If the flooring manufacturer has a warranty for electric floor heating, it should not be adversely affected by shrinkage, expansion, or warping. Again, it will depend on the brand and construction of the product. Some manufacturers may place limitations on the maximum floor heating temperature. To minimize expansion and contraction, some Luxury Vinyl Tile companies require heating the flooring to a continuous heating level with "setback" temperatures (lower temperature settings during the day and overnight) kept to a minimum.

While radiant heating can affect the expansion and contraction of the floor, the most overlooked and important factor is the relative humidity in the space, so a humidifier or dehumidifier may be needed.

Do I need insulation when installing an electric floor heating system over a concrete slab?

When WarmlyYours electric 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 electric floor heating provides 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 electric radiant floor heating system.

When installed on top of a concrete slab without insulation, it is generally accepted that electric floor heating 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 electric radiant 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.

Do I need to apply a layer of thinset over the subfloor first?

Yes, using a square-notch trowel (1/4” x 1/4” or larger), apply a layer of thinset to the subfloor area which will later be covered by the WarmlyYours TempZone™ Flex Roll, Easy Mat or Custom Mat.

Do I need to cut and/or trim the TempZone™ Custom Mats to fit into my room shape?

No, TempZone™ Custom Mats provide the easiest installation with no cut and turns required as they are specifically designed and built based on the dimensions of your project that you've provided to us. Prior to installation, dry-fit your mat to make sure it fits correctly. If there are any issues, call WarmlyYours at 1-800-875-5285. 

Do you have a separate thermostat for the shower?

Bathrooms designed with shower and floor heating will include only one thermostat by default. But it is possible to design with a thermostat for each zone if desired. Installing a separate thermostat for the shower area can help reduce cost and energy usage. This also allows you to heat the bathroom floor alone for everyday use and only heat the shower area when needed.

How can I make my living room feel warmer?

Simply set your floor heating thermostat to a comfortable temperature to maintain a nice warm floor. Your room will feel warmer and, typically, your furnace will cycle less often.

How can I make my room warmer without a heater?

Floor heating will typically add the most heat to supplement an existing heating source and it will not take any extra space since it is embedded in the floor. If you are not remodeling your floors but have some open wall space, you should mount a radiant panel. For the most effective results, install the panel so that it points toward the area where you will spend most of the time.

How do I prepare my living room for extreme cold?

Having floor heating installed and set to a higher temperature during particularly cold days will help to maintain a comfortable temperature level by providing supplemental heat.

How do I test the Bench or Shower mat product?

Test the product using a digital ohm meter as shown here.

And here is a video showing how to do the test.

How do I test the product?

How do I work with my electrician to install WarmlyYours electric floor heating?

While WarmlyYours electric radiant floor heating 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.

How do you keep a sunroom warm in the winter?

Sunrooms can be very cold during the winter months. While a furnace may push some warm air into the room, the large number of windows, exterior walls, and other causes of heat loss in a sunroom will typically keep it from having a comfortable temperature level. Floor heating and radiant panels will add radiant heat, which the human body absorbs faster than other forms of heat, to the room so that it feels warm even at lower temperatures.

How do you waterproof a curbless shower?

When waterproofing a curbless shower, most guidelines require a continuous surface, created by a bonded waterproof membrane, on the floor and walls of the shower itself. The waterproofing should extend outside the shower enclosure for at least one foot beyond the highest point of the floor. Additional waterproofing outside the shower is suggested as a consideration, but is not required.

How effective are radiant electric floor under 3/4" wood flooring?

For best results, we recommend a 1”- 1.5” maximum distance between the heating cable and the top of the floor. Nailed down hardwood will require sleepers to run the cable safely between board nails. Be sure to use 3/8" to 3/4" of self-leveling cement to embed the heating element.

How far does the heat spread laterally from the embedded TempZone Easy Mat?

Heat will spread laterally about 1" to 1.5" from the end of the heating elements. 

How long is the shower or bench mat lead wire and the sensor wire?

The cold lead is 22‘ long and the sensor(included with the thermostat) wire length is 15‘.

How long is the Tempzone lead wire and the sensor wire?

Both are 15 feet long.

How many square feet of floor heating can be connected to one thermostat?

One thermostat can control multiple heating mats/cables as long as all the elements are using less than 15 amps. For TempZone™ Flex Roll systems for example that would be maximum of 120 sq.ft. for 120V systems and 240 sq.ft. for 240V.

How many watts per square foot does TempZone™ deliver?

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.

How much does it cost to install a heated floor in a shower?

WarmlyYours' Shower Waterproofing Kits start at $537, adding a TempZone Shower Floor Heating Kit will bring the total to $846.

How much does it cost to run an electric floor heating system?

The answer to this question will depend on a whole host of variables related to electric floor heating, including, but not limited to, the run time (for supplemental heating, we usually recommend between 4-8 hours per day), the electric radiant floor 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 electric floor heating might cost to run for you, make sure to use our interactive Operating Cost Calculator. 

How will electric floor heating affect my wood floor?

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.

If I have extra cold lead wire, can I trim off what I don't need for my installation?

Yes. Unlike the heating cable for electric floor heating, the cold lead wires can be trimmed or lengthened with additional lead wire which can be purchased from WarmlyYours.

I have too much / too little of the TempZone™ product for the space I want to heat. Can I trim or add more heating cable?

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.

Is a filler needed on the rest of the floor to space the flooring up to the same level?

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 heating system is encased in 3/8" of modified thinset or Self leveling underlayment. You simply use that 3/8" layer throughout the space, eliminating any need for fillers.

Is electric floor heating safe and what about EMF?

Our electric radiant 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

Is installing a floor heating system for LVT the same as for ceramic or porcelain tile?

Yes, Luxury Vinyl Tile (LVT) is typically installed over the embedded heating element using self-leveling cement (SLC). Many people choose to use SLC when installing tile over floor heating.

We do not suggest using thinset to encase the heating wires with LVT, as it is very difficult to get thinset completely flat.

Is the heating element waterproof?

Our TempZone electric floor heating products are waterproof and wet location listed.

Is there a way to heat vinyl flooring without embedding the heating system, such as a floating floor heating system?

There are heating systems designed for floating floors, such as our Environ system. However, the flooring must be rigid enough so it does not mold itself to the heating cables over time.

Check the flooring manufacturer's floor heating recommendations. In most cases, the heating system will need to be embedded beneath the flooring. Check for all "flatness" requirements for the flooring you choose. The flattest floors utilize self-leveling cement when installed correctly.

Is the TempZone™ floor heating system safe?

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.

Is the waterproofing above or below the heating wire?

Waterproofing for the room is in the layer above the floor heating system. The layers for waterproofing this type of floor are:

  • subfloor
  • thinset
  • uncoupling membrane
  • tempzone heating cable
  • waterproofing tape for seams and corners
  • thinset or self leveling cement
  • tile floor

My Ohms are X but the label says they should be Y?

A variance of +/- 15% is acceptable.

Should I be concerned about electric floor heating melting the toilet connection's wax ring?

To prevent any overheating, we recommend that you do not install any electric radiant floor heating elements closer than 4" from the wax ring.

Should you leave underfloor heating on all the time?

An electric underfloor heating system doesn't need to be left on all the time. The system can be completely turned off or set back to a lower temperature when not in use. If you have a programmable floor heating thermostat, then the system can also be set to operate only during specific times.

What does an Ohm (Ω) reading below 15% of the label value indicate?

Resistance below this value may result in no heating or cold spots in the floor. This may be caused by exposure to moisture or other conductive material that penetrates the core insulation.

What does an Ohm (Ω) reading greater than 15% of the label value indicate?

Resistance greater than this value may result in overheating or even total failure of the floor heating system. This may be caused by a crimping or other damage to the wire.

What if I have cracks in my concrete slab? Will that affect the floor heating installation?

Make sure any cracks or raised edges are sanded down before installation. Seal and patch cracks where possible. If needed, pour a layer of self-leveling cement to make sure surface is level and flat. Then proceed with instructions to install desired floor heating system and flooring.


It is strongly recommended that an insulating underlayment be installed between the slab and heating element to prevent heat loss.

What is a good choice, or watt density, for supplemental heat?

Supplemental heat can be addressed by changing the spacing on cable installs. Floor location in the house is very important when considering adding supplemental heating to a floor. For example: If heating a second story floor, over a heated space, cable at 4" spacing can be used. The same type of heating over an unheated space would probably be done with TempZone Flex Rolls or TempZone Cable at 3" spacing. All heating is considered supplemental unless a heat loss calculation is done.

What is spot heating?

Spot heating is a method of floor heating where you only install heating elements under the most highly used portions of a floor (for example: the area in front of a vanity in a bathroom or in front of the stove in a kitchen). Spot heating allows you to enjoy all of the comfort of full coverage floor heating but for only a fraction of the material and operational costs.

What is the BTU output of these systems?

For Tempzone it is 51 BTU’s per square foot per hour and for Environ, it is 41. Take the wattage of the product (shown on the product’s label) and multiply that by 3.41. That is the BTU value for that product.

What is the cost of a heating system?

Heating systems run at approximately $10 per square foot.

What is the maximum temperature for Luxury Vinyl Tile (LVT) when it comes to in-floor heating?

This is stated in the Installation Manual of the LVT product when purchased. On average, this maximum temperature will fall between 80°F and 83°F. This number can then be used to program the thermostat during setup to set the floor's maximum temperature.

What is the polarity of this radiant heating product?

Electric-resistance heating cables and systems have no polarity. This includes all current WarmlyYours heating elements.

What is the recommended temperature for a heated kitchen floor?

Everyone has their own comfortable temperature setting, but we typically find that our customers use their thermostats to set the "floor temperature" of the system in the 78°F - 84°F range.

What is the smallest size TempZone Easy Mat available?

The smallest TempZone Easy Mat is 3' x 2', which is great for heating the area in front of a toilet or shower.

What is the spacing of wire for Tempzone?

At least 3“ from wire to wire.

What is the total power/amperage that the electric floor heating system draws and does this system need a dedicated circuit?

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 electric radiant floor heating system.

What is the typical operating cost of a TempZone™ floor heating system?

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.

What is the WarmlyYours TempZone™ floor heating system?

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.

What is the warranty for the TempZone™ floor heating system? Do you warrant the cost of replacing the flooring installed on top of the system? What if there was a surge that damaged the system?

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 costs AND flooring materials required to perform the repair. We do not cover the cost of flooring that needs to be replaced in the event of a repair necessitated due to damage. If a product is damaged by a power surge, that would not be covered by our warranty

What is wattage output/density of TempZone™ Custom Mats?

The mats provide between 12 and 15 watts per sq. ft. (depending on room size). They are designed to distribute heat evenly for full room coverage. 

What Ohms meter should I buy?

A digital meter with a 0-200 Ohms scale ( Ω ) to measure the heating wire's resistance, and a 20K scale to measure the sensor's resistance.

What should I consider if I want to heat a vinyl or composite material floor?

We recommend verifying 3 things with the manufacturer of the flooring product to be heated;

1.) Is the flooring product compatible with electric floor heating?

2.) What is the maximum temperature the flooring product can withstand?

3.) What is the temperature set back recommendation of the flooring product?

What size breaker do I need?

For systems below 12 Amps, a 15 Amp, Non-GFI breaker is fine. For systems 12 to 16 Amps, a 20 Amp, non-GFI breaker is needed. Breaker sizes are noted on the installation plan that ships with many orders.

What spacing is used for the wire with Prodeso?

3.75“ or every 3rd peg.

What temperature should I set my heated floor to?

The perfect room or floor temperature is always going to be a personal preference. However, we do see that our customers will usually set their floor temperature to somewhere in the 80°F to 84°F range.

What thickness is required for self-leveling cement when installing floor heating for Luxury Vinyl Tile?

We suggest the heating product be embedded in a minimum of 3/8" of self-leveling cement (SLC). Always check with the manufacturer for specific recommendations.

What type of floor preparation is required for Luxury Vinyl Tile (LVT) and radiant heating?

The subfloor will need to be prepared as per the instructions of the self-leveling cement (SLC) used. Please note that most self-leveling products require the use of a primer as specified by the SLC company.

What voltage does a Warmly Yours shower or bench mat utilize?

The shower and bench heating systems are offered in 120 voltage.

What wood species are recommended or not for floor heating? Is Engineered or solid better? Nailed down or floating?

The most important factor for the wood floor chosen is structural stability.

According to the USDA Forest Service, this list shows most dimensionally stable to least: 

  • Mesquite 
  • Australian Cypress 
  • Teak 
  • Santos Mahogany
  • American Cherry
  • South Yellow Pine 
  • Douglas Fir 
  • American Walnut 
  • Brazilian Cherry 
  • Hard Maple 
  • Red Oak 
  • True Hickory
  • American Beech

Engineered is the most structurally stable compared to natural hardwood, so it will work the best with floor heating.
If you do want to go with Hardwood, quartersawn or riftsawn narrow planks are the most structurally stable and would work best for this application.

Overall the most important factor for the room is relative humidity. Keeping a consistent humidity and temperature in the home will help wood floors last for many years to come.

    Which LVT, WPC or Solid Core product can be paired with radiant heating? Is there a list of manufacturers who still provide a warranty when pairing with radiant floor heating?

    LVT (Luxury Vinyl Tile), WPC (Wood Plastic Composite), and Solid Core all fall into the category of "vinyl flooring." These flooring types can be rated for floor heating, but will completely depend on the manufacturer's guidelines.
    Please look in the installation manual and warranty documents of the product you're interested in to see if and what types of heating are allowed.

    As for a list of manufacturers - many do provide a warranty for their products when properly installed with floor heating. The list of these is ever-changing, so please be sure to check with the flooring manufacturer for current recommendations.

    Why does my Ohm (Ω) reading vary slightly from the label?

    Temperature affects core resistance - lower temperatures decrease resistance and higher temperatures increase resistance. Another consideration is the test equipment, sometimes switching test units, adjusting the calibration, or allowing for the verified differential may be necessary.

    Will the flooring manufacturer still warrant with electric floor heating underneath?

    Always check with the flooring manufacturer to see what they will cover when it comes to floor heating. In most cases there will be a floor temperature limit - this can be programmed into a programmable or smart thermostat. Check for installation instructions and requirements before adding floor heating.

    Will the installation of a TempZone™ floor heating system affect the height of my floor?

    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.

    Will the other sections of the floor without TempZone Easy Mats installed directly underneath be cold?

    Yes, the areas without heating elements installed directly under them will be largely the same temperature as they would be if there was no heating system at all. So you'll want to keep that in mind when you're looking to use spot heating in your floor heating project. You can always choose to have multiple TempZone Easy Mats incorporated into your project to created several heated "spots".

    Will the radiant heat affect the attached rubber or cork backing on Luxury Vinyl Tile? Does the attached backing have any effect on the floor heating system?

    Since most Luxury Vinyl Tile (LVT) manufacturer's set a maximum temperature for radiant floor heating, the system should have little to no effect on the rubber/cork backing.

    Pre-attached backing can act as an insulating layer though, meaning it can prevent the radiant heating from efficiently directing heat up through the floor. Please check with the manufacturer for the r-value of the product. Look for an assembled plank with an r-value of less than 1. The lower the r-value, the better!

    Would the installation process be different if Luxury Vinyl Tile was installed in a bathroom?

    No. A bathroom floor would be installed in the same way. Our TempZone floor heating systems are wet-location listed and ideal for bathroom floors.
