What is ThermoTile Cable?
ThermoTile Cable is a loose heating cable system designed for ceramic and stone tile installations. ThermoTile uses FiberThermic heating elements, or high quality heat cables to apply gentle radiant heat to your flooring. ThermoTile gives you the greatest flexibility by arranging in any pattern with an uncoupling membrane. Pairing loose cable with a Ditra-Heat membrane gives you all the benefits of an uncoupling membrane and also makes the layout of your loose cable easy. Uncoupling membranes add stability to your tile floor, and in certain applications provide a thermal break. The studs in the Ditra-Heat membrane give you a guide for spacing your loose Thermotile Cable.
Is this a safe product to put in my home or business? What about Electromagnetic Field/EMF?
Yes. All our floor heating solutions endure rigorous development and in-house US quality control testing to ensure that your floor heating system is reliable and safe. Due to the shielding used in ThermoSoft products, our radiant heat systems add virtually zero EMF.
Can I use ThermoTile Cable with my floor material?
ThermoTile cable with Ditra-Heat membrane is only compatible with tile floors. If you are heating another type of floor, be sure to check out our floor materials pages that will give you guidance for selecting the right system for your floor covering.
How do I install ThermoTile Cable? How does it all get connected?
ThermoTile Cable is embedded in mortar or self-levelling cement under your chosen floor material. Just have an electrician make final connections to the thermostat and to your home’s electrical system. Explore our installation guides and resources for more information! ThermoTile Cables are wired to a floor heating thermostat in parallel. The number of cables and layout of the room will affect the exact process of how to wire things together. Please see the Installation Manual for explicit directions, or contact our experts for assistance.
Will this add height to my floor?
Minimal, ThermoTile cable and DITRA-Heat Membrane will add 1/4" to your already planned tiling project. Remember, ThermoSoft does offer ThermoFloor and WarmStep as options that do not need to be embedded in cement to be installed under a wood, vinyl, or laminate floor.
Can I combine more than one ThermoTile Cable to fit a space?
Many projects involve using more than one heating cable, but this means that multiple cables are wired in parallel to the thermostat. The thing to remember is that you are not daisy-chaining heating cables, but rather the cables are working together to cover the appropriate square footage of your heated area.
Can I cut, shorten, or reshape the system?
You CANNOT cut the heating cable as this will damage the heating cable preventing it from heating up and void your warranty. In some applications, reducing the spacing used as you run the cable through the Ditra-Heat membrane can allow you to fit a cable into a slightly smaller space than is our standard estimation. Consult with us or a qualified professional before deciding to pursue this method. If you need additional answers to the questions about cutting, shortening, and reshaping ThermoTile, just give us a call so we can match the right length of cable to suit your needs!
Can I shorten the lead wires?
The lead wires, also known as cold leads because they do not produce heat, can be cut, shortened, or spliced with additional cold lead cable to lengthen them.
Is this Ditra-Heat membrane something that I really want in my floor?
Absolutely. Ditra-Heat membrane paired with our superior heating cables adds a number of benefits to a standard tile floor.
How many watts per square foot does ThermoTile Cable output?
The standard output is about 12 watt per square foot at 3 inches average on center spacing. But his figure can vary if the cable spacing deviates.
How much will it cost to run this system?
The cost to operate is a complicated question to answer, as electrical rates vary by area, the home's insulation, and even by time of day. Additionally, a cost-to-operate is further complicated because the money spent on your radiant heat can result in a net savings on total utilities cost due to reduced use of your traditional HVAC, which is added to by the fact that you will spend less on HVAC system maintenance by relying on electric radiant heat. So, keeping in mind the nuances of describing the operating costs of an electric radiant heat system, just contact us to discuss this as it would relate to your specific project.
How hot does ThermoTile get?
Sometimes, we have to answer a question with a follow-up question. Usually, we are asked about “how hot” a system gets for a couple of reasons, so it is important to know why do you ask? Are you concerned about providing enough heat to adequately warm your space? If so, a properly installed ThermoTile Cable can provide about 10-15 degrees Fahrenheit of temperature difference above the ambient temperature of the room. In practice, this is more than enough, even in extremely cold climates. We are positive that you will be entirely satisfied with the heat produced by ThermoTile. Are you concerned about applying too much heat to your chosen floor material? If so, fear not! ThermoTile is designed to have a gentle, reliable, and consistent delivery of heat to your floor material. Just give us a call if you need some guidance. Lastly, we highly recommend choosing a thermostat that includes a temperature limiter if this is one of your concerns!
How long will ThermoTile Cable last? How long is the warranty?
ThermoTile has a lifetime limited warranty and we have yet to see a ThermoTile Heating Cable fail due to old age. ThermoTile requires no regular maintenance once installed correctly and if left undisturbed (remember your radiant system is installed under your floor covering when planning a remodel!). The thermostats that we offer are warrantied for 3 years because we only use thermostats with GFCI protection which, per national electric code, is recommended to be replaced every 3 years. Replacing a thermostat is simple, easy, and inexpensive.

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.
