ThermoTile® Electric Floor Heating Cable with Schluter DITRA HEAT® Membrane

ThermoTile® floor heating cable, when paired with Schluter® DITRA-HEAT membranes, creates a reliable and efficient heated floor system for ceramic and stone tile installations in bathrooms, basements, kitchens, hallways, and other living spaces. ThermoTile® cable delivers comfortable radiant heat through the floor surface, while the DITRA-HEAT membrane securely holds the heating cable in place and simplifies installation. In addition to cable management, the membrane provides uncoupling, waterproofing, vapor management, and load distribution, helping to protect tile installations and enhance long-term performance.

What is ThermoTile® electric floor heating cable?
ThermoTile® Heating Cable is an electric radiant floor heating cable designed for embedding in mortar thin set. It is installed under porcelain, ceramic and tile, stone tiles, in any part of your house including bathrooms, kitchens, hallways, basements and four-season rooms. Loose heating cable construction allows flexible spacing and custom layouts when embedded in mortar, thin set, or self-leveling cement.
Is ThermoTile® electric floor heating cable safe for my home or business?
Yes. ThermoTile® electric floor heating cable is designed and tested for reliable electric floor heating in residential and commercial spaces. All ThermoTile® heating products are UL approved and listed. ThermoTile® floor heating cables are constructed to emit virtually zero Electro Magnetic Fields (EMF).
What floor types can ThermoTile® electric floor heating cable be used with?
ThermoTile® electric floor heating cable is most often used under ceramic tile and natural stone, but it can also be embedded in thin set, mortar, or self-leveling cement under many other compatible floor coverings. For wood, laminate, vinyl, or carpet projects, WarmStep® Electric Heating Mats or ThermoFloor® Electric Heating Mats may be easier options.
How is ThermoTile® electric floor heating cable installed?
ThermoTile® electric floor heating cables are laid out across the heated area and secured with FixFast cable holding strips. Alternatively, ThermoTile® heating cables can be laid out across Schluter, Prodeso or Prova uncoupling membranes in the recommended pattern and spacings, and then embedded in mortar or self-leveling cement. Final electrical connections should be made by a licensed electrician according to the ThermoSoft installation manual.
Will ThermoTile® electric floor heating cable and Ditra-Heat Uncoupling Membrane add height to my floor?
ThermoTile® electric floor heating cable and Ditra-Heat Uncoupling Membrane will add 1/4" to your already planned tiling project.
Can I use more than one ThermoTile® electric floor heating cable in a room?
Yes. Many projects use more than one ThermoTile® electric floor heating cable. Multiple heating cables are electrically wired in parallel to the thermostat. They should not be daisy chained or connected in series.
Can I cut ThermoTile® heating cable?
No. The ThermoTile® electric floor heating cable must never be cut, shortened, or altered. Cutting the heating cable will damage the system and void the warranty. Contact ThermoSoft to help choose the right cable length.
Can I shorten the cold lead wires?
The ThermoTile® cold lead wires do not produce heat and may be shortened or extended by a qualified electrician according to the installation manual and local code requirements.
What happens in areas not covered by ThermoTile® electric floor heating cable?
It is normal for some areas of room to remain unheated. The installer should create a level mortar or self-leveling compound bed across both heated and non-heated areas.
When should I choose ThermoTile® floor heating cable instead of ThermoTile® floor heating mats?
Choose ThermoTile® electric floor heating cable when the room has an irregular shape, tight turns, custom spacing needs, or areas where a pre-spaced ThermoTile® heating mat may not fit cleanly. ThermoTile® heating Mats are often easier for installation in open areas, while ThermoTile® heated cable offers more layout flexibility.
What is a Ditra-Heat Uncoupling Membrane, and why would I use it with ThermoTile® electric floor heating cable?
A Ditra-Heat Uncoupling Membrane is a plastic uncoupling membrane used in tile floor installations. When paired with ThermoSoft ThermoTile® electric floor heating cable, it helps hold the cable in a consistent pattern, supports the tile assembly, and helps reduce the risk of tile cracking caused by minor movement in the subfloor.
How many Watts per square foot does ThermoTile® electric floor heating cable produce?
ThermoTile® electric floor heating cable produces about 10 to 12 Watts per square foot, depending on cable spacing.
How much does ThermoTile® electric floor heating cable cost to operate?
Operating costs depend on the heated area, cable spacing, local electricity rates, floor and the whole house insulation, thermostat temperature settings, and how often the system runs. For a specific project estimate, contact ThermoSoft’s US experts.
How warm will ThermoTile® electric floor heating cable make the floor?
A properly installed ThermoTile® electric floor heating cable system can typically raise the floor temperature by about 10 to 15 degrees Fahrenheit above the room’s ambient temperature. A thermostat with a floor sensor helps manage comfort, energy savings, and floor protection.
How long will ThermoTile® electric floor heating cable last?
ThermoTile® electric floor heating cables are very durable and reliable. They do not have any moving or wearable parts requiring regular maintenance once installed correctly and left undisturbed. ThermoTile® floor heating cables have a Lifetime Limited Warranty. Thermostats are warrantied separately.
Who can help me choose the right ThermoTile® electric floor heating cable?
ThermoSoft’s US experts can help confirm cable size, layout, voltage, thermostat needs, and installation approach before you order.

Combine cables as needed to fit open walkable space, avoiding areas covered by cabinets, vanities or other permanent fixtures. The heating cable cannot be shortened, so avoid over-filling. Each cable will connect to the thermostat, so larger cables will reduce required connections. At 3 stud spacing on a sole thermostat, 120V cables cover up to 175 ft²; 240V cables cover up to 350 ft². DO NOT MIX VOLTAGES. Contact us for project assistance or help finding a local dealer/installer.

A floor heating thermostat is necessary to control your radiant heat system. Most of our floor heating thermostats are dual-voltage and include a 5ma GFCI, unlike models from online warehouse retailers. A thermostat is capable of a 15-Amp load; adding a power module or relay will increase system load capacity. Each includes a floor sensor, but a backup is recommended. Select 1 thermostat for each zone desired. Contact an expert for guidance.
