Luxury Vinyl Tiles Design Guide

Follow our detailed guide and learn how to install electric floor heating under luxury vinyl tiles.

What is Floor Heating?

All radiant heating systems rely on a thermal mass. The heat moves from the source (Heating Element) into a thermal mass (thin-set) and spreads out and warms the floor without creating any excessive hot spots. In the WarmlyYours Floor Heating System, the thin-set and/or self-leveling cement acts as a thermal mass. It is important to follow the installation guidelines to create a proper thermal mass.

Radiant floor heating is also a very clean heat source since it doesn’t rely on forced air, which can circulate dust and other allergens. All of our electric floor heating products have been rigorously tested and are cULus or cCSAus listed.

WarmlyYours Floor Heating Systems

Our electric underfloor heating systems are available in a wide range of heating elements including rolls, cables, and heated floor mats. Any room in the home can utilize radiant heat providing comfort wherever you are.

Due to it’s flexibility, luxury vinyl flooring should almost always be installed over an embedded heating system, such as TempZone™ Flex Rolls or TempZone™ Cables. In most cases, LVF cannot be paired with our Environ floor heating system.

This guide will walk you through a single heated floor installation under luxury vinyl tile using our TempZone™ Flex Roll or TempZone™ Cable heating system.

 

Start Smart with a Free SmartPlan

Perhaps the most important stage in installing a floor heating system is getting a good installation plan.

WarmlyYours provides a free, no-obligation SmartPlan that includes an installation plan, an electrical plan, and an itemized quote, all of which is prepared by a highly skilled team of engineers.

All you have to do to take advantage of this service is to provide WarmlyYours with a sketch of the project that includes dimensions and other relevant information, like where power will be most readily accessible.

Within typically one day of providing this information, you'll receive your free SmartPlan. The itemized quote included in your SmartPlan will also include MSRP pricing so that you can properly budget for your project.

When to Install a Floor Heating System

Because the electric floor heating system is installed under the flooring itself, the best time to install is either during new construction or remodeling.

Since the floor heating system is electric, it can easily be added on to in the future if these homeowners replace the original flooring at some point.

How to Choose LVF for Radiant Heat

Here's a few things to consider when choosing luxury vinyl flooring for your project:

  • Try to find LVF with no or minimal backing
  • If there is a foam/rubber/cork backing, you may want to remove this to improve the efficiency of your floor heating system
  • Look for an assembled plank with an R-value of less than 1
  • Check the warranty of your flooring choice: Is it compatible with radiant floor heat? What is the maximum temperature?

Installing the Floor Heating System

Be as specific as possible when working with a sales rep or our online quote builder to describe the type of flooring being used for the project. When adding radiant heating, always check with your manufacturer to confirm whether it will affect the flooring warranty. The following steps will illustrate how to best install radiant floor heating beneath luxury vinyl flooring.

Verify dimensions on plan match the location’s actual dimensions. Make sure to check the luxury vinyl flooring for which subfloor it is designed for. Primer should be used on wood subfloors to help self-leveling cement bond with the surface. Prepare the subfloor to be clean and free of debris.

If you're installing using a TempZone™ Flex Roll system, use the included custom design or cut & turn sheet to plot your path beginning closest to the thermostat location and utilizing a wire down/mesh up configuration as much as possible. Following the design, cut the fiberglass mesh with scissors to create “panels”. Position the panels around fixtures using cuts and turns to accommodate the system design layout and proper room coverage. NEVER cut the heating wires, cut the mesh only.

Once the roll(s) is fitted into the space, it needs to be secured to the subfloor to prevent movement during the installation of the floor covering. Staple, hot glue, or tape the mat panels and cold leads to the sub floor every 6-8 inches. Staples should never cross, pierce or nick the Heating Element, and never be used to secure the cold lead.

TempZone Cable on Plywood Subfloor with Fixing Strips

If you're installing using a TempZone™ Cable system, you should attach the included fixing strips to the subfloor using concrete nails, double-sided tape, hot glue or strong spray adhesive. The cable then should be wrapped around the strips in a serpentine pattern. Make note of the halfway point on your SmartPlan with the white mark on the cable.

Never fold or position the cable so that it overlaps itself or other wires. The heating portion of the product should never touch, cross over, or overlap itself. This will cause dangerous overheating.

Tempzone Flex Roll with floor heating sensor

Install the floor sensor 6” into the mat directly centered between the heating wires using tape. NEVER staple the heating wires or floor sensor wire.

Tip: Always test a floor sensor and verify 8-15 kOhm resistance. A secondary backup sensor may be installed, but only one can be connected to a thermostat at a time.

Luxury Vinyl Tile LVT with TempZone Flex Roll and Self Leveling Cement

Once you have everything in place, you’re ready for self leveling cement. If you're using TempZone™ Cable, make sure it does not lift up while pouring, you may need to tape across the rows of cable every few feet.

The self-leveling cement should be a 3/8 – 1/2” layer on top of the floor heating elements or as required by the manufacturer.

Making Sure the Manufacturer’s Splice is Embedded in Concrete

The power lead (D) is 15-feet in length. The lead is spliced to the Heating Element (E) at the factory. If necessary, this lead wire may be shortened or even extended.

Please note the thickness of the factory splice and cold lead and plan accordingly. The factory splices must be completely embedded in thinset or self-leveling underlayment.

120 Cold Lead In Gang Box

The system should be attached to the thermostat and then the thermostat is wired to the home electrical system and installed in a wall box by a licensed, certified electrician.

Ensure supplied voltage to thermostat matches heating system’s.

Tip: Dedicated non-GFI circuit is typically needed for the heating system to avoid any nuisance tripping or interference. The GFCI feature is incorporated in the thermostat.

Layout for Snow Melting Mats

After the SLC has dried to the approved manufacturer spec, you can begin installing your LVT/LVP flooring. We recommend following directions provided by the flooring manufacturer concerning subfloor moisture levels and flooring acclimation schedules.

Commissioning The System

Allow proper thinset cure time as recommended by the manufacturer (typically 7-28 days) before powering up the WarmlyYours electric radiant heat system.

Tip: When commissioning the system or adjusting the temperature setpoint, follow flooring manufacturer temperature restrictions/recommendations. Temperature limits can be set under ”Floor Protection” setting on the thermostat.

Floor Heating Thermostats

A great thermostat is the secret to any great heating system. Not only is it the way you control the temperature, it’s also how you customize your comfort.

Our nSpiration Series of controls offers a wide variety of options — from programmable models, to controls that will allow you to easily monitor and manage your home comfort remotely from any device. All of our controls are designed to help you get the most out of your floor heating system.
