To prevent any melting, ensure that the heating wire is at least 4” from the toilet wax ring.

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.

14 people found this helpful Was this helpful? Yes No

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.

10 people found this helpful Was this helpful? Yes No

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.

3 people found this helpful Was this helpful? Yes No

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.

2 people found this helpful Was this helpful? Yes No

Self-Leveling (SLC) Cement is not recommended for use over Prodeso. Contact WarmlyYours if self-leveling underlayment is required.

2 people found this helpful Was this helpful? Yes No

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.

2 people found this helpful Was this helpful? Yes No

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.)

2 people found this helpful Was this helpful? Yes No

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.

1 person found this helpful Was this helpful? Yes No

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.

1 person found this helpful Was this helpful? Yes No

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.

1 person found this helpful Was this helpful? Yes No

Prodeso installation membrane does not eliminate the need for expansion joints (adhere to local codes).

1 person found this helpful Was this helpful? Yes No

Unroll the membrane the day before installation to flatten it and avoid any potential ‘memory’ due to environmental conditions.

1.25"

The wire spacing in the Prodeso Cable Installation Membrane is 3.75“, or every 3rd peg.

1 person found this helpful Was this helpful? Yes No

Not a good choice for mosaic tile work, Prodeso requires 2“ x 2“ or larger tiles.

Was this helpful? Yes No

Yes, radiant floor heating can be a primary heat source if its heat output exceeds the room's heat loss. For best results, we recommend using a 15-watt system, covering at least 80% of the floor, and ensuring the space is well-insulated. Use our Heat Loss Calculator to verify your specific needs.

Was this helpful? Yes No

Yes, radiant floor heating is an excellent primary heat source for tiny houses in mild to moderate climates. Because tiny houses have small footprints, the 15-watt output of TempZone™ can easily maintain comfort while saving valuable wall space. Ensure the structure is well-insulated and use our Heat Loss Calculator to confirm.

Was this helpful? Yes No

Yes, we strongly recommend installing insulation like ThermalSheet™ over concrete slabs. Concrete acts as a "heat sink," absorbing warmth that should go to your floor. Insulation directs the heat upward, significantly improving efficiency, reducing warm-up times, and allowing the system to function effectively as a primary heat source.

Was this helpful? Yes No

Underlayment is recommended for floating floors (laminate, LVP, wood) and installations over cold subfloors like concrete. It provides thermal insulation to prevent heat loss and improves system efficiency. For tile and stone, the system is typically embedded in thinset, so a separate underlayment is often unnecessary.

Was this helpful? Yes No

WarmlyYours TempZone™ Flex Rolls and Easy Mats deliver 15 watts per square foot, the maximum allowed by the National Electrical Code. This provides 25% more heating power than the 12-watt industry standard. TempZone™ Cable can be spaced to deliver between 8 and 15 watts per square foot depending on your needs.

Was this helpful? Yes No

Yes, electric radiant floor heating is ideal for basements because it warms the cold concrete slab and provides consistent heat from the ground up. In well-insulated finished basements, it can serve as the primary heat source, turning a typically chilly space into a comfortable, year-round living area.

Was this helpful? Yes No

Radiant floor heating can heat a sunroom if the space has high-quality insulation and double-pane glass. Since sunrooms have high heat loss, a 15-watt system is essential. In extremely cold climates or poorly insulated sunrooms, it is best used as a supplemental source to keep the floor comfortable.

Was this helpful? Yes No

When laying Prodeso installation membranes adjacent to each other, align the square relief pegs for the later heating element cable runs.

Was this helpful? Yes No

Most systems provide only 12 watts per square foot, which often lacks the power for primary heating in cold climates. WarmlyYours TempZone™ delivers 15 watts—a 25% increase. This higher output allows the system to overcome heat loss more effectively, providing reliable primary warmth even when outdoor temperatures drop.
