What are ThermoTile mats?
ThermoTile Mats are the main heating component of a complete electric in-floor heating system for tile, stone and other floor coverings. ThermoTile is available as either a mat system or loose cable. In either form, ThermoTile uses FiberThermic 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. As a ThermoTile mat, your project is even easier to lay out because we have spaced and arranged the cable for you, and your floor is strengthened by the fiberglass mesh used to create our mat!
Are ThermoTile mats safe for 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.
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, because it uses a fiberglass mesh to add strength and durability to a tile floor installation. This doesn’t mean it is only for tile, as ThermoTile can be embedded in a thin-set or self-levelling cement and laid under almost any material. 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 mats? 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 mats or cables are then wired to a floor heating thermostat wired in parallel. The number of mats and layout of the room will affect the exact process of how to wire things together. Please see the full ThermoTile Installation Guidelines for explicit directions.Shop Now
Will ThermoTile mats 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 wood, vinyl, or laminate floor.
Can I combine more than one ThermoTile mat to fit a space?
Many projects involve using more than one mat or cable, but this means that multiple mats are wired in parallel to the thermostat. The thing to remember is that you are not daisy-chaining cables or extending the mats, but rather the mats are working together to cover the appropriate square footage.
Can I cut, shorten, or reshape the system?
Yes, not really (no cutting heating elements!), and yes. The fiberglass mesh that is used in ThermoTile mats is meant to be cut in order to reshape the mats in a “cut and turn” method. You CANNOT cut the heating wire as this will alter the performance of the heating element and void your warranty. This “cut and turn” method might end up effectively shortening the mat system and depending on the number of mesh cuts and turns, you may “shrink” the coverage area of loose cable. However, and we know we sound like a broken record here, but you CANNOT cut the heating elements and maintain performance and warranty coverage. The best answer to the questions about cutting, shortening, and reshaping ThermoTile? Just give us a call so we can match the right size mat or 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.
What do I do with areas not covered by the heating system?
ThermoTile mats or cable allows for almost complete coverage of most room sizes and shapes because of the flexibility of arranging loose cable or cutting and turning the mat system. 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.
Is this mesh on ThermoTile mats something that I really want in my floor?
We see a lot of our competitors use mesh that is just barely “good enough” to achieve a mat layout. That wasn’t something that we were comfortable doing, so we selected a high quality, exceptionally strong, anti-fracture fiberglass mesh that adds strength and durability to your floor. As always, consult with a qualified building professional in your area to make your decisions about your building materials, but we are confident they will be satisfied with the components of ThermoTile.
How many watts per square foot does ThermoTile 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, 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 long will ThermoTile last? How long is the warranty for ThermoTile mats?
ThermoTile requires no regular maintenance once installed correctly and if left undisturbed (remember your radiant system is down there when planning a remodel!). ThermoTile mats and cable have a lifetime limited warranty and we have yet to see a mat 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.
