All three Warm Tiles® systems provide comfortable electric floor warming, but each offers a different installation approach.

DFT Heating Cable Kits offer excellent flexibility for irregularly shaped rooms. The loose heating cable is secured with installation strapping, making it easy to work around vanities, toilets, kitchen islands, and other fixed obstacles.

DMC Membrane Cable Kits are designed for installations using a compatible uncoupling membrane. The heating cable fits into the membrane's channels, providing a convenient way to combine floor warming with a membrane-based tile installation.

WTE Elite Heating Mats are an excellent choice for straightforward layouts and projects where minimizing floor height is important. The heating cable comes preassembled within a thin fabric mat, making installation especially convenient for rectangular areas.

All three systems are available in 120-volt and 240-volt configurations and are intended primarily to provide supplementary floor warming.

Thermostats are selected separately, allowing you to choose the control features that best suit your needs.

The original SAM heating mat systems have been discontinued and are no longer offered through EZFloorHeat.

Fortunately, there are excellent alternatives.

For rectangular areas, WTE Elite heating mats offer a convenient, low-profile installation. For rooms with irregular shapes or obstacles, DFT heating cable and DMC membrane cable systems provide greater layout flexibility.

If you're replacing an older SAM system or planning a similar installation, we can help you explore the available options.

Our standard WTE Elite heating mats are available in a variety of factory-made rectangular sizes, making them suitable for many common floor layouts.

If your project has an unusual shape, DFT or DMC heating cable may offer a more practical solution because the cable can be routed around fixed obstacles.

Custom WTE configurations may be available by special quotation. Contact us with your project dimensions, and we'll be happy to review the possibilities.

Warm Tiles® systems are designed primarily to make your floors comfortably warm underfoot while supplementing your home's existing heating system.

Although heated floors contribute warmth to the surrounding space, they should not automatically be considered a replacement for conventional room heating.

Actual performance depends on several factors, including floor construction, insulation, heating cable spacing, floor covering, room heat loss, and thermostat settings.

If your goal is to use electric radiant heat as the primary heating source, a qualified professional should evaluate the room's heating requirements and confirm whether a suitable system can meet them.

Warm Tiles® heating kits include the primary heating components, but some installation materials and accessories are purchased separately.

DFT kits include heating cable, installation strapping for a typical rectangular layout, a floor temperature probe, clips, and installation instructions. More complex layouts may require additional strapping.

DMC kits include heating cable and installation instructions. The compatible uncoupling membrane is purchased separately.

WTE Elite kits include the preassembled heating mat, factory-installed cold lead, and installation instructions.

Thermostats, mortar, thinset, membranes, and other flooring materials are generally selected separately. Floor sensors may be supplied with the heating kit or thermostat, depending on the product.

Review the contents of your selected kit before ordering so you have everything needed when installation begins.

Warm Tiles® systems are particularly well suited for ceramic tile, porcelain, natural stone, marble, granite, and other compatible cement-set floor coverings.

Certain laminate, luxury vinyl, and engineered wood flooring products may also be suitable when the flooring manufacturer specifically approves installation over electric radiant heating.

For these materials, it's important to confirm any maximum floor temperature, underlayment requirements, and installation restrictions before selecting your heating system.

Flooring installed with nails or staples is generally unsuitable because fasteners can damage the heating cable. Carpet and certain resilient flooring products are also restricted depending on the heating system.

Regardless of the finished flooring material, the heating cable must be installed and fully embedded or enclosed in the approved assembly as required by EasyHeat®.

Yes, certain luxury vinyl plank and engineered wood flooring products can be installed over electric floor warming systems, provided the flooring manufacturer specifically approves their use with radiant heat.

The heating cable or mat must first be installed within the approved mortar or membrane assembly. It should never be placed loose directly beneath floating flooring.

Before purchasing, confirm the flooring manufacturer's temperature limits and any special installation requirements.

A little planning at this stage helps ensure that your finished floor and heating system work together as intended.

Certain Warm Tiles® heating cable installations may be suitable for tiled showers when the manufacturer's installation requirements and applicable electrical and building codes are satisfied.

The heating cable must remain fully embedded within the approved mortar assembly, with an appropriate waterproofing system above the heating cable to prevent water exposure.

Ground-fault protection is required, and the thermostat must be installed outside the wet location.

Because shower construction involves additional waterproofing and electrical considerations, we recommend reviewing the installation with your contractor and local building authority before purchasing or installing the system.

The amount of added height depends on the heating system, installation materials, and finished flooring.

Here are approximate heating-system dimensions before accounting for all mortar and finished flooring layers.

DFT heating cable and strapping: 0.21–0.344 inches.

DMC with a typical uncoupling membrane: 0.387 inches.

WTE Elite assembled mat: 0.211 inches.

WTE Elite is often an excellent choice when keeping floor height to a minimum is especially important.

Be sure to consider the complete finished floor assembly, particularly around doorways, adjoining rooms, and other floor transitions.

The same DFT heating cable can be used in approved installations over wood subfloors and concrete slabs. The primary difference is often the recommended cable spacing.

For floors above heated living spaces, standard 3-inch spacing is commonly used.

For concrete slabs or floors above unheated spaces, alternating 3-inch and 2-inch spacing provides a higher heating output to help compensate for greater heat loss.

Always use the spacing pattern approved for your specific product and floor assembly. Cable spacing should never be reduced beyond the manufacturer's limits.

Not usually. For most installations, the goal is to warm the open floor areas where people stand and walk.

Permanent fixtures such as cabinets, vanities, toilets, bathtubs, and kitchen islands are generally excluded from the heated area.

You also don't need to extend heating cable all the way to every wall. Leaving the manufacturer's required perimeter clearance is a normal part of the layout.

For the most accurate product selection, measure the usable floor area rather than relying on the room's overall square footage.

Our Build My System tool can help you work through these measurements.

Proper spacing helps your heating system distribute warmth evenly and operate safely.

For the applicable Warm Tiles® cable installations, maintain at least 1½ inches between heating cable runs and from walls, vanity kick plates, and other fixed fixtures, subject to the manufacturer's instructions.

Heating cables must never touch, cross, or overlap.

When installing adjacent WTE Elite mats, the outer heating wires should generally remain between 1½ and 3 inches apart to promote consistent warmth across the floor.

Always follow the spacing requirements for your particular product and installation.

Rooms with L-shaped layouts, narrow hallways, kitchen islands, toilets, or other fixed obstacles are often excellent candidates for DFT or DMC heating cable systems.

Unlike fixed rectangular mats, loose heating cable provides the flexibility to route around obstacles while maintaining the required spacing.

WTE Elite mats can also work in rooms with multiple rectangular heating areas by placing compatible mats alongside one another.

The important distinction is that the heating cable itself cannot be cut or shortened to accommodate the room.

Yes. Dividing a room into separate heating zones can give you more control over when and where the floor is warmed.

For example, a large kitchen might have one zone for the main cooking area and another for an adjoining breakfast area.

Each independently controlled zone requires its own thermostat and appropriate floor sensor.

A zone may contain one or more compatible heating kits, provided the electrical load and installation meet the manufacturer's requirements.

Heating products operating at different voltages must not be combined on the same thermostat.

Cable spacing determines how much heating cable is installed within a given floor area and influences the system's heating output.

For DFT systems, standard spacing places adjacent cable runs approximately 3 inches apart. This is commonly used for floors above heated spaces.

Alternating spacing uses a repeating 3-inch, 2-inch pattern. It provides additional heating output and is commonly recommended for concrete slabs and floors above unheated areas.

Current DFT plastic installation strapping has 1-inch notch spacing, making it straightforward to follow either pattern.

Older DFTCK metal strapping uses different hole spacing and corresponding coverage requirements. Be sure to use the sizing information associated with your actual installation components.

The selected spacing pattern should be maintained throughout the zone, and cable should never be concentrated beyond the manufacturer's permitted limits.

DMC heating cable fits into the channels of a compatible uncoupling membrane. The membrane's molded pattern helps establish consistent cable spacing.

Three spacing options are available for suitable installations:

Standard: 12 watts per sq. ft.

Alternating: 15 watts per sq. ft.

Dense: 18 watts per sq. ft.

The appropriate pattern depends on the floor construction and heating requirements.

Because uncoupling membranes can differ in hub spacing and channel dimensions, confirm compatibility before purchasing. The manufacturer's DMC instructions and the membrane manufacturer's requirements should both be followed.

For a consistent installation, select the approved spacing pattern that best suits your floor construction and use it throughout the heating zone.

Combining standard and alternating spacing within the same zone can produce uneven heating and may create areas where the cable spacing falls outside the product's approved installation requirements.

If different parts of your project have substantially different heating needs, separate zones may be worth considering.

This is a common situation, and choosing the right kit is important.

Each heating cable kit has a specified coverage range based on its approved installation spacing. Small adjustments to the layout and perimeter clearances may help accommodate the available kit sizes.

The goal is to select a cable or combination of kits that provides appropriate coverage without leaving excess heating cable.

Because heating cable cannot be shortened, purchasing a kit that's too large can create an installation problem.

If your measurements fall between sizes, contact us before ordering. We're happy to help you compare your options.

No. The heating portion of a Warm Tiles® cable or mat must never be cut, shortened, or modified.

Each heating cable is manufactured to a specific length and electrical resistance. Altering that length can affect its electrical characteristics and create a safety hazard.

Only the nonheating cold lead may be shortened where permitted by the manufacturer's instructions, while maintaining the required lead length and identification information.

If a cable is too long for your intended layout, the correct solution is to select a more appropriate kit size.

Manufacturer-authorized repairs to damaged cable are a separate procedure and should never be used simply to reduce cable length.

Both voltage options provide effective floor warming when properly matched to the installation.

The correct choice depends primarily on the electrical circuit available and the total heating load.

120-volt systems are commonly convenient for smaller areas, while 240-volt systems can accommodate larger heating loads with lower current for the same wattage.

Neither voltage is inherently better at warming the floor. What matters is selecting the correct product for your circuit and project.

Your electrician should verify the available voltage, circuit capacity, and connected load before installation.

Never connect a heating product to a voltage other than the one specified on its label.

Warm Tiles® FGS, ES, and ESW thermostats are rated to switch up to 15 amps at either 120 or 240 volts, subject to the manufacturer's installation requirements.

When multiple heating cables or mats are connected to one thermostat, their combined electrical load must be considered.

For larger installations, an appropriately selected RK-1 or RK-2 relay can allow additional heating loads to be controlled while keeping the thermostat within its rated capacity.

A qualified electrician should confirm the circuit and relay configuration, including any required continuous-load derating.

You may notice a 10-amp reference in certain DFT manufacturer warranty or installation documentation.

This relates to the manufacturer's requirement for qualified electrical installation when certain cable combinations exceed 10 amps. It does not replace the thermostat's published 15-amp switching rating.

For larger installations, your electrician should review the total connected load, circuit protection, thermostat rating, and applicable installation requirements.

Yes. Multiple compatible heating cables or mats can often share a thermostat when they are installed within the same heating zone.

The products must operate at the same voltage, and the total connected load must remain within the capacity of the thermostat and any properly installed relay system.

Multiple heating products are connected electrically in parallel, not end to end.

A properly positioned floor sensor allows the thermostat to monitor and regulate the zone.

For larger or more complex installations, have your electrician confirm the electrical arrangement before connecting the system.

Choosing a thermostat comes down to how you'd like to control your heated floor.

FGS Programmable Thermostat: A practical choice for customers who want reliable, scheduled floor warming. It features a digital display and flexible 5/2-day or 7-day programming.

ES ColorTouch Thermostat: Offers an easy-to-use 3.5-inch color touchscreen, with programmable schedules and options for monitoring floor temperature, room temperature, or both.

ESW Wi-Fi ColorTouch Thermostat: Provides the touchscreen features of the ES, plus Wi-Fi connectivity so you can manage your floor warming schedule remotely using a compatible phone or web browser.

All three are designed for compatible 120-volt and 240-volt Warm Tiles® systems and include ground-fault protection.

The older FG dial thermostat has been discontinued. For most new installations, we recommend selecting the FGS, ES, or ESW based on your preferred features.

Not necessarily. All compatible Warm Tiles® thermostats are designed to provide reliable floor temperature control.

A Wi-Fi thermostat simply adds the convenience of managing your floor warming system remotely.

With the ESW ColorTouch thermostat, you can adjust settings or schedules from your phone or a compatible web browser, making it especially convenient when you're away from home or your daily routine changes.

If you prefer to control everything directly from the wall, the FGS or ES may be all you need.

Yes. The FGS, ES, and ESW thermostats include built-in ground-fault circuit interrupter (GFCI) protection designed to help protect against electrical faults.

The FGS includes Class A protection, while the ES and ESW provide 5 mA ground-fault protection.

Because additional GFCI devices on the same heating circuit can sometimes cause unwanted tripping, your electrician should follow the thermostat manufacturer's wiring instructions and applicable electrical codes when selecting circuit protection.

Never bypass a GFCI or repeatedly reset one that continues to trip. A persistent trip should be evaluated by a qualified professional.

Warm Tiles® thermostats are designed for installation in a suitable electrical wall box in a dry indoor location.

Choose a convenient, accessible location away from direct water exposure. Thermostats should not be installed inside showers or other prohibited wet locations.

Also consider the distance between the heated floor and the thermostat. The heating system's factory-installed cold lead and floor temperature sensor must reach the electrical box in accordance with the manufacturer's requirements.

DFT and DMC systems typically include 10-foot cold leads, while WTE Elite mats have 15-foot cold leads.

Planning the thermostat location before installing the floor helps avoid unnecessary complications later.

The floor temperature sensor allows your thermostat to monitor the heated floor and maintain your selected comfort setting.

For accurate readings, install the sensor within the heated area, approximately halfway between two adjacent heating cable runs.

Position it away from cable return loops, fixed cabinets, unheated borders, and locations exposed to unusual temperature conditions, such as direct sunlight.

The sensor should be embedded within the approved mortar assembly without touching or crossing a heating cable.

Follow the placement dimensions in your product's installation instructions. For applicable DFT installations, the sensor is positioned at least 6 inches from the cable return loop.

A replacement floor sensor is available under catalog number 10739001.

The Detecto™ DT-1 is a helpful installation accessory designed to provide an early warning if heating cable is damaged while you're working.

During installation, the monitor connects to the heating cable's cold leads and sounds an alarm if it detects certain changes indicating possible damage.

This can be especially valuable while positioning the cable, applying mortar, or installing flooring, when accidental damage may otherwise go unnoticed.

The DT-1 is not a substitute for the required electrical resistance and insulation tests, and it is not designed to locate faults beneath an already finished floor.

Disconnect the monitor before energizing the heating system.

The DFTRK is a specialized repair kit intended for certain damaged Warm Tiles® heating cables when repair is authorized and performed according to EasyHeat®'s instructions.

It's designed to address eligible cable damage, not to shorten an oversized heating cable or change its original heating capacity.

If you suspect your heating cable has been damaged, contact us or EasyHeat® technical support before attempting a repair.

Proper testing and manufacturer guidance are particularly important when the heating cable has already been covered by finished flooring.

The accessories you need depend on your heating system and the shape of your installation.

DFT heating cable kits include installation strapping for a typical rectangular layout. Rooms with hallways, islands, or other irregular features may require additional DFTS plastic strapping.

DMC membrane cable installations use the membrane's channels to position the heating cable. Additional DMCS components may be needed for certain layouts.

Other accessories, including approved concrete installation tape, are available for applications that require them.

Always use compatible installation materials. Improper substitutes, particularly sharp metal materials, can damage heating cable insulation.

RK-1 and RK-2 relays are used when a floor warming installation requires additional electrical switching capacity beyond what a single thermostat can directly handle.

The RK-1 is designed for 120-volt applications, while the RK-2 is designed for 240-volt applications.

In a properly designed installation, the thermostat controls the relay, allowing additional heating loads to operate through the appropriate electrical circuits.

These accessories are especially useful for larger heated areas.

Your electrician should determine whether a relay is needed and confirm the appropriate circuit, enclosure, wiring, and load ratings.

Yes. The entire heating portion of the cable must be properly embedded in the manufacturer-approved mortar or installation assembly for safe operation.

This includes any heating cable that travels between separate heated areas. For example, if one continuous cable warms both a bathroom and an adjoining dressing area, the cable connecting those areas must also remain fully embedded in mortar.

Heating cable must never be left exposed, routed through wall cavities, or installed loose beneath flooring.

The factory cold-lead splice and cable termination must also be positioned and embedded as required by EasyHeat®. The thicker splice may need to be recessed into the subfloor to maintain a smooth finished surface.

Only the designated nonheating cold lead should be routed to the electrical connection point.

For DMC installations, follow the specific membrane and encapsulation requirements approved by the manufacturer.

Ideally, there shouldn't be any extra heating cable.

Warm Tiles® cables are manufactured in fixed lengths, so choosing the appropriate kit size and planning the layout beforehand are essential.

All heating cable must remain within the approved floor installation at the required spacing.

Never coil excess cable, place it inside a wall cavity, tuck it beneath a cabinet, or leave it outside the approved mortar assembly.

If your layout cannot accommodate the full cable length, stop and review the kit selection before proceeding.

DFT and DMC heating cables are designed to accommodate changes in direction, making them suitable for a variety of room layouts.

However, the cable must never be sharply kinked, crushed, or bent more tightly than the manufacturer's permitted minimum bend radius.

For applicable DFT and DMC products, the minimum bend radius is approximately ¾ inch.

Use the recommended strapping or membrane channels to hold the cable in place. Never drive staples, nails, or screws through the heating cable itself.

You'll need to allow the installation materials to cure before operating your new floor warming system.

Although WTE Elite mats can accommodate tile installation during the same installation session, that doesn't mean the heating system can be energized immediately.

Thinset, mortar, grout, and other setting materials require adequate curing time. Turning on the heat too soon may interfere with the curing process.

Follow the setting-material manufacturer's curing instructions and EasyHeat®'s startup requirements before operating your system.

Once everything has properly cured, you'll be ready to enjoy your new heated floor.

Testing your heating cable at several stages is one of the most important ways to protect your investment.

EasyHeat® requires electrical checks before, during, and after installation to help identify potential damage before the finished flooring is completed.

The recommended testing stages are:

Before installing the cable, while it's still on the spool or in its original packaging.

After positioning and securing the heating cable, before covering it.

After completing the flooring installation, before energizing the system.

The required tests include heating conductor resistance, insulation or ground-braid checks, and floor sensor resistance. Additional insulation testing may be specified.

For applicable products, conductor resistance should fall within the manufacturer's stated tolerance relative to the factory label. The referenced DFT guidance specifies -5% to +10%, with additional insulation and sensor resistance requirements.

Record your measurements and keep them with your installation documents. These records can be extremely helpful if troubleshooting or warranty service is ever needed.

Electrical testing should be performed with the circuit de-energized and by someone qualified to perform the required measurements.

If your electrical resistance readings change unexpectedly after installation, don't energize the heating system until the cause has been investigated.

Compare the latest measurements with those recorded before and during installation.

A significant change may indicate damage to the heating cable, a connection problem, or another issue requiring further testing.

Contact EZFloorHeat with your product catalog number and recorded measurements. We can help you determine the appropriate next step and connect you with EasyHeat® technical support if necessary.

Avoid removing finished flooring or attempting a repair before receiving manufacturer guidance, as unauthorized work may affect warranty eligibility.

There are several common reasons a heated floor may not feel warm, and many are related to thermostat settings or electrical controls rather than the heating cable itself.

Start by checking that the circuit breaker is on and the thermostat has power.

Next, confirm that the thermostat's GFCI protection hasn't tripped and that the thermostat is set to operate the floor heating system.

If your thermostat offers different sensing modes, verify that the floor sensor is being used as intended. Set the desired floor temperature a few degrees above the current reading and allow time for the system to respond.

Concrete slabs and other substantial floor assemblies can take several hours to noticeably warm.

If the floor still doesn't respond, consult our Troubleshooting resources or contact us for additional guidance. Electrical faults and repeated GFCI trips should be evaluated by a qualified professional.

A GFCI is an important safety feature that helps protect against electrical ground faults.

If your thermostat's GFCI repeatedly trips or won't reset, the system may have an electrical problem that requires attention.

Possible causes include damage to the heating cable, cold lead, connections, or another component of the installation.

For your safety, don't bypass the GFCI or repeatedly reset it without identifying the cause.

A qualified electrician can review the electrical connections and required test measurements. If the results suggest heating cable damage, EasyHeat® technical support can provide further direction.

A cooler area doesn't necessarily mean your heating system has failed.

Floor temperature can vary because of cable spacing, floor construction, heat loss, and the location of the heating elements.

For example, a wider-than-recommended gap between adjacent mats or cable runs may create a noticeable cooler strip.

Areas near walls, fixtures, or unheated borders may also feel different from the center of the heated floor.

If the temperature difference seems excessive, review the installation layout and thermostat sensor location. Increasing the thermostat to its maximum setting generally won't correct an area that wasn't properly covered by heating cable.
