What is ThermoTile?
ThermoTile is an electric floor heater designed primarily for ceramic and stone tile installations. It is available as either a mat system or loose cable. In either form, ThermoTile uses FiberThermic conductive fiber heating elements, or high quality heat cables to apply gentle radiant heat to your flooring. In loose cable, ThermoTile give you the greatest flexibility by arranging in any pattern with either FixFast strips or an uncoupling membrane.
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 quality control testing in our US manufacturing center 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.Shop Now
Can I use ThermoTile with my floor material?
ThermoTile is one of our most universally applicable floor heating systems. Obviously, it is most frequently used under tile, however, ThermoTile can be embedded in a thin-set or self-levelling cement and laid under almost any floor covering including vinyl or concrete. Almost any floor covering you would like to heat can be heated by ThermoTile, just keep in mind that for materials like wood, vinyl, or laminate, we might have an easier-to-install system available rather than ThermoTile.
How do I install ThermoTile? How does it all get connected?
ThermoTile 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 heating 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 call us anytime.
Will this add height to my floor?
No, tile installation projects will not see any added floor height. However, if you are deciding to apply ThermoTile under a vinyl floor, for example, the need for self-levelling cement poured over the heating mats will cause an addition to the floor height that you would need to plan around. Remember, ThermoSoft does offer ThermoFloor and WarmStep as options that do not need to be embedded in cement to be installed under a solid or engineered wood, vinyl, or laminate floor.
Can I combine more than one cable to fit a space?
Many projects involve using more than one 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 cables in series connections, but rather the heating cables are working together to cover the appropriate square footage of heated area.
Can I cut, shorten, or reshape the system?
You CANNOT cut the heating cable as this will alter the performance of the heating element and void your warranty. The best answer 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 cable to lengthen them.Shop Now
What do I do with areas not covered by heating system?
ThermoTile Cable allows for almost complete coverage of most room sizes and shapes because of the flexibility of arranging loose cable in any shape. However, almost every project will result in some areas that are not heated. This is entirely normal, and any competent floor installer will be able to achieve a fully level bed of mortar or self-levelling compound throughout the heated and non-heated areas.
How many watts per square foot does ThermoTile Cable output?
This figure can vary if the cable spacing deviates from the 3 inches on center spacing, but the standard output is about 12 watts per square foot.
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, insulation of the home, 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, we recommend talking to one of our experts about the operating cost of your individual 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. ThermoTile Cable is most frequently applied under tile, which is a floor material that can handle a high variation in temperatures. If you are heating a more temperature sensitive floor material, you can ensure a healthy floor with appropriate use of your thermostat. Just give us a call if you need some guidance. Lastly, we highly recommend choosing a floor heating thermostat that includes a temperature limiter if this is one of your concerns!
How long will ThermoTile last? How long is the warranty?
ThermoTile requires no regular maintenance once installed correctly and if left undisturbed (remember your radiant system is down there when planning a remodel!). ThermoTile has a lifetime limited warranty and we have yet to see a heating cable fail due to old age. The thermostats that we offer are warrantied for 3 years because we only use thermostats with GFCI protection which, per national electric code, should be replaced every 3 years. Replacing a thermostat is simple, easy, and inexpensive.
