WarmWire floor heating cables are similar in construction and provide heat just like SunTouch mats, but install differently and cost less. Simply place and attach the WarmWire strap to the subfloor and weave the wire back and forth between straps to create your own heated area. Cover with thin-set or self-leveling mortar and finish with almost any floor covering. You weave the wire onto the subfloor while maintaining the spacing of wires.
Nuheat is the easiest way to get a heated floor, since the mats are pre-built for you!
No. All mat voltages must match incoming Line voltage. 240v circuit must be used with only 240v mats. Combining mats of different voltages on a circuit or supplying the incorrect voltage to a mat cannot be done under any circumstances.
Since each mat uses a specific wire size, extending a wire will risk premature failure and provide too little heat to the floor.
No. That will ruin the mat. Each mat uses a different wire size and is built with a specific ohm (resistance) value, so the length must remain as it came from the factory.
If you shorten the heating element you risk premature failure and overheating. You may shorten only the power lead wire or the sensor wire.
Absolutely you can repair your Nuheat floor heating mat.
Yes, but be very careful so as not to damage the mat. See detailed instructions.
Nuheat requires a line voltage thermostat different from an HVAC thermostat, which operates at 24v. There are three thermostat options for controlling your Nuheat electric floor heating system and all include 5mA Class A GFCIs built-in for your safety.
Nuheat is an economical floor heating system. For example, a 25 square foot heated area of Nuheat will use only about the same amount of electricity as three 100-watt light bulbs. You will reduce energy costs even further by using our energy efficient programmable thermostat.
Not as long as you use one of our Thermostat’s with GFCI protection built-in; then a regular circuit breaker of proper amperage with available load is fine. If contactors or relays are used, your installation will require additional protection – check with your electrician to ensure the installation is done according to all applicable codes and all installation instructions are followed.
Ground Fault Circuit Interrupter. This safety device terminates the electrical power to the radiant heat system immediately in the event of damage to a wire or another catastrophe. A GFCI is required by electric code for floor heating applications, just like it’s required in most North American bathroom outlets. We always recommend one of our floor heat sensing Thermostats with its built-in GFCI protection.
There is no up or down. Either side can be up or down, so you cannot do it wrong.
Absolutely! Nuheat Mats are built to ensure your safety. Nuheat’s innovative design encapsulates every wire within the mat in two layers of insulation; the standard plastic insulation that all wires are required to have and an additional outer braid of stainless steel.
The cold lead (aka power lead or cold tail) is 10’ long and can be shortened freely. If you need a LONGER lead it can be extended in 2 ways

Warm tiles can be yours overnight with the Nuheat under floor heating system.
People often ask us if they should be using cork insulation for their heated concrete flooring. We tell them that many contractors & homeowners recommend that you insulate between an existing concrete slab & your new Electric Radiant Floor Heating System. Insulation is not required, but many customers like to install a "thermal break" while they are installing new floor heating. Heat transfers to cold material, meaning warm objects or surfaces transfer heat to cold ones. An Insulating material on top of the slab and under the Electric Radiant Floor Heat elements will slow the transfer of heat from the heating elements into the bottom of the slab and effectively decrease the time it takes your floor warming system to warm the part your floor that matters.
Changing out your ceiling heat for floor heat systems is easy! On the same exact circuit floor heat can heat the same zones that were heated using the ceiling heat! Replacing your old ceiling heat with floor heat prevents your head from overheating and gets the heat to where you need it..your feet! Here at Warm Your Floor, we have had many customers replace their failed or failing ceiling heat with floor heat.
(An example of this would be adding a 1.5 Amp 180 watt Towel Warmer onto a Floor warming circuit of 10 amps / 1200 watts).
The electric radiant floor heating you find in many homes these days has come a long way. Did you know that underfloor warming has been around since nearly 5,000 B.C.? These primitive methods weren’t nearly as advanced as a SunTouch or NuHeat system, but the core concept of radiating heat in the floor hasn’t changed.
The key to heating any structure is providing more heat than is lost through the walls, windows and doors. Adequate insulation is key to preserving the heat generated. Smaller windows are better with energy efficient glass to hold heat in the space than large single-pane glass style. this goes the same with doors – insulated doors are a better choice than non-insulated as well.
This is based on the recommendation of thinset and grout manufacturers. Their products require a curing period before the masonry reaches its full strength. This process cannot be rushed by heating and apparently, the process can be adversely affected by the modest temperatures of the heating wires if they are turned on before 28 days (according to the thinset manufacturers).
Since each WarmWire spool uses a specific wire size, extending a wire will risk premature failure and provide too little heat to the floor.
WarmWire cannot be installed below built-ins, cabinets or walls, but rugs, hampers, scales and waste cans are OK when your finished floor is stone or ceramic. The area under the rug or other objects will get warmer, but will not cause any damage to the heating element or masonry floors. If you use any other type of flooring other than ceramic however, check with the floor manufacturer to make sure their product is suitable for a radiant floor and the objects commonly found on them.
We offer an Industry Leading 25 year warranty that is unusual in our industry. We think the product will last a great deal longer because of several design decisions we made years ago. The great danger to any heating cable in a bathroom floor is oxidation caused by moisture. So, we use a very expensive wire insulation called Tefzel by DuPont. The physical properties of this polymer are unmatched for the application, notably its water resistance, dielectric properties and long-term temperature aging. We also use oxygen-free alloys in our heating elements to give them greater longevity. No one builds a better heating element wire than WarmWire. Compare our wire construction to other systems - your choice will be clear. Furthermore, Watts is a 135 year old USA manufacturer, with $1.4 Billion in sales. So there's a Real USA manufacturer standing behind the warranty. Not an importer or offshore manufacturer. WarmWire is made in America, by Americans, for American homes. Several competitors produce their products offshore, but not WarmWire.
Radiant floors should not exceed 85 degrees F at the surface. 85 degrees is our skin temperature, so anything warmer starts too feel too warm. Floor coverings other than stone or tile REQUIRE a maximum temperature below 85 F. Most people are very comfortable between 75-80 degrees F.
We recommend using a 3/8 inch x 1/4 inch trowel to apply the thinset over the wire and by the time you have finished, you will be approximately 1/4 inch over the backerboard which is usually 1/4 to 1/2 inch thick. For perimeter areas where there is no WarmWire, you will simply apply a slightly thicker layer of thinset.
Start with a good quality latex-modified thinset. Use the flat edge of a 3/8 inch x 1/4 inch notched trowel to push the thinset over and into the wire. Then reverse the trowel and use the “comb” side to rake the mortar over the wire in straight parallel lines. Work in small areas.
WarmWire is the ONLY manufacturer that has undergone INDEPENDENT testing for EMF or Electro Magnetic Field emission. The results of this testing shows WarmWire Floor warming to be the SAFEST with the LOWEST emissions. See the results don't just take a website's claims as truth or believe everything you read - look To WarmWire for Safety and testing to support our statements.
EMF stands for Electro Magnetic Field and is a byproduct of alternating electric current passing through wires and appliances. Human exposure to ambient levels ofEMF is the subject of continuing scientific scrutiny and the results are a matter of public record. For those who are concerned, the Federal Government recommends minimizing exposure to EMF in the home and workplace. Elevated EMF levels can also interfere with electronic devices including computer screens and audio equipment and is usually included on lists of causes for “sick building syndrome” and sources of interference.
There is no practical technology to completely shield an electric heating element in order to minimize EMF. The only viable approach is to spiral two wires side by side so the fields cancel each other. Watts Radiant innovated this approach years ago and was granted U.S. patent number 6,303,905. The EMF generated at floor level by radiant floor heating systems that use only one wire is many times normal ambient levels. Using dual wires for EMF cancellation is more expensive, but it is the safest choice. Any single wire heating element used in radiant floor heating is a compromise and should, in our opinion, be avoided.
Safer electronic emission practices have been adopted by manufacturers of microwave ovens, video monitors and cell phones to name a few. WarmWire has already taken this important step and is another reason why it is your safest and best choice for Floor Warming. Other Manufacturers minimize the importance of EMF…Could this be because they do NOT meet the same superior standard WarmWire meets? Is it worth the risk to you and your family? We do not think so.
This space next to walls reduces the chance of damage to the wire by in new construction or future remodeling. If these issues are not relevant in your case, it is OK to put wires within 3 inches of the wall. Definitely stay at least 4" from the toilet ring. Another good reason for the gap is to save you money. In most cases, you do not stand closer than 6” to a wall so you can use less wire by leaving a space.
If you shorten the heating element you risk premature failure and overheating. You may shorten ONLY the power lead wire or the sensor wire.
Yes. Install & attach Radiant Floor heat such as, WarmWire or Nuheat Cable to your subfloor and cover with a thin layer of self leveling mortar on top. This will add only slightly more than a quarter inch rise to your floor. The mortar spreads the heat evenly and helps protect the heating wires from sharp objects that might penetrate the floor. This installation is UL Approved. Be wary of systems that install directly under carpet - check for a UL Listing and assess their ability to withstand furniture placement and safety in the event the carpet gets wet by a spill or accident.
We know of one manufacturer of a wire for directly under carpet; but we will not sell it. We simply do NOT believe it is safe. It has a short warranty and is made offshore. What happens if you put a heavy piece of furniture right on a wire with this wire? We'll stick with our quality products that get encased in a thin layer of mortar for YOUR protection.
Here are a few rules of thumb:
1. 1/8 inch to 1/4 inch of thinset over the plywood
2. Then, 1/4 inch or 1/2 inch backerboard.
3. Then, the WarmWire wire.
4. Then 1/4 inch to 3/8 inch thinset over the WarmWire.
5. Finally, 1/4 to 5/16 inch tile.
So, the overall thickness of your completed WarmWire tile floor will be about 7/8" - 1" thick. This is only about 1/8 to 1/4 inch thicker than a cold floor without heat.
Your WarmWire will be embedded in latex modified thin set mortar. The heating element will not be affected by the residual glue.
14 gauge AWG electrical wire is appropriate for a load of 15 amps in most city electrical codes, but in all cases, follow your local code.
SunTouch radiant mats are UL Listed for use with any type of finished floor if you embed it in at least a quarter inch of masonry. As always, start with a strong subfloor, secure the SunTouch, and cover with a self leveling mortar of your choice. Once this mortar is in place, follow the manufacturer instructions for cure time and then cover with laminate or carpet. Our Favorite Self Leveling manufacturer is ARDEX. Other Manufacturers are Custom Building Products and Mapei.
No. The mat may go through a doorway but never through a wall. UL requires the heating wire to ALWAYS be embedded in mortar.
Yes. Check instruction manual to see how to connect up to three mats together in series to the LoudMouth. Remember to disconnect them before connecting to the FloorStat.
All slab-type radiant systems work best if you do not use an “on or off” strategy to control the temperature. Instead, use a modern, programmable, floor sensing control that turns the temperature down (called a “setback”) to a preset temperature when the floor is satisfied, but keeps residual heat in the slab to respond quickly when the floor starts to cool off. Each home is different, but start with a 5 degree F setback to see if the room responds the way you want. If not, you can adjust the floor temperature, setback temperature and lead time features of the programmable thermostat to get the performance you want. Try the SunTouch Programmable FloorStat and we think you will be very pleased. For smaller areas, say under 30 square feet, you might just want to install a non-programmable control and leave it on throughout the heating season.
Yes. We recommend using our double-sided tape to hold the SunTouch mat to the membrane, then thin-set as you normally would. Many customers have had success with our Premium Cork underlayment or WEDI board as well.
You can connect up to 3 mats totalling 150 Sq Ft of 120V and 300 Sq Feet of 240V SunTouch mat to one SunStat (15 Amp Load). More than 3 mats makes for an unsafe wire connection in the electrical box and violates most electric codes. So, keep it to 3 mats or less — simply choose larger mats from our selection of 67 sizes in 4 widths. You could also use a series of junction boxes to connect more mats to one SunStat, but this is seldom necessary or cost effective when you can simply choose the right mats for your project. Or, let us help you choose the correct mats.
Our mat is Underwriter Laboratory (UL) Listed for interior floor heating. We are not UL Listed for snow melting because the wire is not designed to give off enough heat for that purpose. SunTouch mats do work great for heating steps around spas and tubs. You simply need more wattage to melt snow. If you want to melt snow or heat outside areas, consider Nexans cables.
No. This also is dangerous and should never be done. The mat voltage must match the Line voltage supplied to the thermostat.
Yes, if you are using the SunStat Controls (500670 or 500675) since these superior controls use a Class 1 sensor wire, which is approved for use in the same conduit as the power lead. If you are using any other control, you must run the sensor and power leads separately.
We do not recommend it because the heat transfer will be poor below the tub. If it is a Claw foot or other free standing tub, it is acceptable to use up extra mat under this open type of tub.
SunTouch radiant mats are UL listed for use with any type of finished floor if you embed it in at least a quarter inch of masonry. But, first make sure the vinyl flooring manufacturer rates their product for use with a radiant floor. The #1 & #2 manufacturers of Resilient Flooring, Mannington & Armstrong approve radiant heat under their products, as long as the Surface temperature is 85 Degrees F or below. Please check with the manufacturers instructions.
We do not recommend the use of flooring adhesives with SunTouch. They are not designed to withstand the operating temperatures of a radiant floor. Self leveling mortars or latex modified mortars are the preferred bonding coat. Check with the manufacturer of your vinyl floor to see if the product is temperature rated for use with a radiant floor before you begin installing.
Normally, we recommend you consider a “crack isolation membrane” when installing SunTouch over an old floor, especially if the old tile is broken, cracked, or has other symptoms of slab or tile failure. If the old floor looks good (and has been there for several years), then make sure the mortar you use is recommended by the manufacturer for bonding to existing tile.
Yes. Simply tape the mat to the mortar with the double sided tape in our installation kit and lay your tile or stone as you normally would. When in doubt, apply more tape. Thinset spreads easier when the mat is thoroughly attached. You can also use a hot glue gun and put drops onto the mesh joints and masonry from above.
No, you can not cut the blue wire in SunTouch Mats, that will ruin the mat. Each mat uses a different wire size and is built with a specific ohm (resistance) value, so the length must remain as it came from the factory.
Yes. Some tile installers would rather work over very flat surfaces and they prefer this two step method. First they cover the SunTouch mat with a self leveling mortar or they apply a level skim coat of thinset over the mat. Once dry, they spread thinset while applying tile. Many installers secure the mat to the backerboard and immediately apply thinset and tile. This is a one-step method. Both work fine, so it's a matter of personal preference. In both cases, we recommend using the Loudmouth monitor during the entire installation.
Yes. Ideally, get a licensed electrician to make the repair. Call us toll free and we'll send your electrician a repair kit. A detailed instruction sheet is also available for direct download. If the mat has not been installed, return it to Warm Your Floor for replacement. If the mat is damaged after installation and it is not feasible to take it up and return it, it can be repaired in the field with a SunTouch Repair Kit.
If a break in the wire is suspected after the tile is installed, it will be necessary to obtain a “Fault Finder” detector, which can help determine the location of a break, typically within 2 SF. A good tile setter can carefully remove the tile and expose the wire. Once you find the break, the electrician will separate the elements of the wire and splice the two sections back together again. The connections are tested and then covered with a section of shrink tube that provides waterproofing. Then an ohm reading is taken again. The repaired assembly is then re-embedded below the tile in fresh thinset. Call our toll free number with any questions you have at any part of the process: 866-558-3369 or the factory @ 888-432-8932.
Mudrooms and Sunrooms are excellent choices for floor warming. Warm floors help moisture dry and sunrooms are often added after the primary heating systems have been completed, so adding radiant floor heat can be a major improvement. We hear frequent stories from people who have bathrooms over garages. Regardless of the insulation level in the floor, the temperature in the room is going to approach the temperature in the garage. While that might be OK for a car, your feet will be ice cold. Similarly, any room that is cantilevered over an open area or illuminated with big north facing windows is going to be a comfort problem. SunTouch mats can make a wonderful improvement in those rooms. Warm bathroom floors of any size - and SunTouch Radiant Floor Heat is not just for the bathroom - use it almost anywhere - its even UL approved for use in the shower floor.
SunTouch is not made in custom sizes, because our 67 different standard mats can fit ANY space. Start with the right sized mat (We will help if you want!) and then cut the orange weave to make right or left turns, 90 degree turns and U-turns. You can install around any obstacle in your room - a column, heat vent, kitchen island, etc. but, never cut the blue heating wire. By making these turns, and sometimes pulling out the blue heating wire from the orange mat to fill small, curved or angled areas, you can precisely heat any size or shape room. You can see hundreds of example room drawings in our Design Library. The Design library can help you choose a layout that closely matches your floor plan, and you can order right away!
Glass, ceramic, porcelain, stone, marble, granite and slate floors are all excellent choices with radiant floor heat. 1”x1” Mosaic to 4' x 4' slabs of Limestone You’re only limited by your creativity – see our complete installation instructions for details on tiles smaller than 6”. If you're not sure – call us toll free 866-558-3369.
We have Mat Sizes For the Smallest to Largest spaces. Need to warm a small 10 Sq Ft. area? We have 3 mats choices to help! If you have a little mat left over, you can always use up a square foot of mat by pulling out the blue wire and laying it along the side and behind the toilet. But, you can Never cut the blue wire to shorten the mat. We stock all sizes to help you fit any shape or size room - that is how flexible SunTouch is. Our largest job is almost 8,000 Sq feet UNDER CARPET right here in Sunny Southern Calif! And we have helped do thousands in between - Let yours be next!
No. Both have the same efficiency and both mats use 12 watts per square foot. 240 volt mats operate with half the amperage (current) of 120 volt models. The 240 volt models are more popular for larger installations of over 150 Sq Ft, for rooms where you want a lower amperage service, or for rooms where 240V is already in place. Once again, SunTouch has thought of all the options!
An emerging issue in the electric radiant heat industry is EMF (electromagnetic frequency) radiation. Some electric radiant floor heating companies sell only single-wire systems that release very high levels of EMF. Other radiant heat flooring companies have pioneered and sell only dual wire EMF-canceling technology. Electromagnetic fields (EMF) come from all electrical appliances, but studies show
