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.

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 heating elements are using less than 15 amps:

TempZone™ will cover aprx. 120 sq. ft. for 120V systems and 240 sq. ft. for 240V systems on one thermostat.

Environ™ will cover aprx. 150 sq. ft. for 120V systems and 300 sq. ft. for 240V systems on one thermostat.

Slab Heat will cover aprx. 90 sq. ft. for 120V systems and 180 sq. ft. for 240V systems on one thermostat.

Would the TempZone 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.

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.

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.

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.

What is the difference between crack isolation and a decoupling membrane?

A decoupling membrane protects the installation from differential expansion/contraction between the substrate and the flooring, relieving almost all shear stresses. Crack isolation protects the installation by isolating the flooring from minor in-plane substrate cracking.

How do I install tiles over the Prodeso membrane?

Install membrane over entire floor first, then heating cable, then do the tiles 1 or 2 at a time. Never cover the Prodeso entirely with thin-set first. Only apply as much thin-set as needed to lay a couple of tiles at a time.

How do I flatten the Prodeso membrane when it arrives in a roll?

Is Prodeso membrane waterproof?

Waterproofing is recommended under and around tubs/showers. It’s also recommended wherever the tile could possibly be exposed to considerable amounts of water. Prodeso is naturally waterproof, but the corners and seams need to be treated with waterproofing tape and thin-set. (Use Pro WP Waterproofing Band 5“ - Soft polyethylene tape – to seal seams.)
