Floor Heating Systems for Luxury Vinyl Tile

Our TempZone™ product line is the ideal match for under vinyl floor heating because each of the products are designed to be embedded within a layer of thinset or self-leveling cement. Not only does this process create exceptionally even heating throughout the room, but it also helps provide a flat surface that makes installation easier and prevents thinner vinyl flooring products from conforming to the shape of the heating wire when warm.

Frequently Asked Questions


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 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 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.

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. 

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 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 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.

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 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 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 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.

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.

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 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.
