TempZone™ Ruler Cable is ultra-low EMF by design and is available in two voltage options and a range of lengths to meet the requirements of any installation.
Features
High-visibility ruler marks at every half-inch, inch and foot for cable layout.
Available in 120V or 240V lengths; 3.7W per linear foot, or 9–15W per square foot depending on spacing.
Install with fixing strips or an uncoupling membrane beneath suitable tile, stone, marble or luxury vinyl floors.
TempZone™ cables can be installed using two different methods, each with distinct advantages.
Choose based on your subfloor condition, project timeline, and whether you need uncoupling protection.
Cable with GripStrips
The traditional installation method. Self-adhesive GripStrips attach to the subfloor, and the cable
snaps into place at your desired spacing (3″, 4″, or 5″). Cost-effective and proven reliable for any room shape.
Best For:
Stable, crack-free subfloors
Budget-conscious projects
Irregular room shapes
Custom heat coverage
Key Details:
Free GripStrips included
Floor sensor included
Requires thinset/SLC to cure before tiling
Cable with Prodeso Membrane
Premium installation using our Prodeso uncoupling membrane. Cable snaps into pre-formed channels at 3.75″ spacing.
Tile can be installed directly over the membrane—no waiting for thinset to cure.
Best For:
Crack-prone subfloors
Tile and stone floors
Faster project timelines
Bathrooms & wet areas
Key Benefits:
Uncoupling & crack isolation
Waterproofing (with accessories)
Direct tile installation
Even load distribution
Still Deciding? Watch Both Methods Side-by-Side
Scott compares both pathways from an engineering perspective—what sits under the tile decides
your heat-up time, your finished floor height, and whether the tile survives.
Three things that catch installers out:
Prodeso needs tile at least 2″ × 2″. Small mosaics and penny tiles flex
into the hollows between the studs under point loads and shear the thinset bond. Choose
fixing strips and SLU for those.
Fixing strips and SLU build the lowest profile—about 3/8″ total—and handle
tight, irregular layouts that a sheet membrane can't follow cleanly.
Prodeso is not a thermal break. It has no R-value, so over concrete a
ThermalSheet underlayment goes down first or heat-up times and running costs both suffer.
The trade-off in short: Prodeso finishes in a single day and adds crack isolation and
waterproofing; SLU takes longer to cure but encases the cable and accepts any tile size.
Cable Installation Accessories
Enhance your cable installation with our underlayment and accessory solutions. Prodeso membrane provides uncoupling protection, ThermalSheet adds insulation over concrete, and GripStrips secure cables at consistent spacing.
A cost-effective alternative to using the Prodeso Cable Installation Membrane, GripStrips Floor Heating Cable Fixing Strips are used for securing TempZone™ floor heating cables in place on floors at predetermined spacing to ensure even heating. These plastic strips enable you to keep the heating cable secured in... (TC-GRIPSTRIP)

Every complete WarmlyYours floor heating system—TempZone™, Environ™, or Slab Heat—ships with two floor sensors: one with the heating mat or cable and one with the thermostat. Install the backup right beside the primary sensor and run both leads to the thermostat box, but connect only the primary; the backup stays disconnected until it is needed.
The floor sensor lives under your tile, wood, carpet, or concrete, where it tells the thermostat how warm the floor really is. If that sensor is ever nicked during installation or fails years down the road, replacing it would normally mean tearing up the finished floor.
With the backup already embedded in the floor, the fix takes minutes: turn off power at the breaker, disconnect the original sensor at the thermostat, connect the backup, and your heat is back on. No torn-up floor, no new flooring, no second installation. Follow your thermostat's instructions, or have a qualified electrician make the swap.
Installer tip: Install both sensors side by side, centered between the heating wires, and test each one for 8–15 kΩ before covering the floor. For Slab Heat, place the sensors in capped 3/4″ rigid metal conduit between cable runs, clear of the heating cable, as the Slab Heat installation manual describes.
Floor Type Compatibility
Floor heating cables are compatible with a variety of flooring types. Choose the right system based on your floor covering.
*1 Slab Heat systems are embedded in the concrete slab; any finished flooring can be installed over the cured slab. *2 Prodeso membrane is designed for tile/stone with thinset. Wood/vinyl/carpet floors use Grip Strips instead. *3 Floating floors and stretch-in carpet require Environ™ mats, or use Slab Heat Cable for in-slab heating. *4 Floating floor can be installed over an embedded TempZone system in 3/8–½" self-leveling cement (SLC), fully cured.
Every floor heating cable needs a compatible thermostat. Our most popular options combine easy
installation with precise temperature control.

Yes. While there are some floor heating systems that can be installed beneath floor joists, most electric radiant floor heating systems will need to be installed beneath the floor itself. This is why the best time to install electric floor heating is during a remodel or as a part of a new construction, when a floor is being installed anyways.
If you’re interested in alternative radiant heating methods, check out our Infrared Heating Panels, which are wall-mounted and use infrared technology to provide supplemental heating.

Supplemental heat can be addressed by changing the spacing on cable installs. Floor location in the house is very important when considering adding supplemental heating to a floor. For example: If heating a second story floor, over a heated space, cable at 4" spacing can be used. The same type of heating over an unheated space would probably be done with TempZone Flex Rolls or TempZone Cable at 3" spacing. All heating is considered supplemental unless a heat loss calculation is done.

Electric floor heating works by having an electric heating cable installed underneath the flooring (embedded or floating, depending on the system and floor type), which is then wired to a special thermostat (either one specifically designed for electric radiant floor heating, like a WarmlyYours’ nSpiration Series control, or a third-party thermostat). When turned on, the heating cable emits heat upward through the flooring which is then radiated throughout the room, heating all solid surfaces.

No. Never cut the heating cable. The floor heating cable is designed with a very specific resistance in order to consistently maintain heating at the chosen wattage per square foot. Trimming the heating cable would lower the resistance of the cable causing the system to overheat. Adding heating cable to the system would raise the resistance and the system would not heat properly.

TempZone™ is an electric floor heating system that operates like an electric blanket for your floors. TempZone™ is covered in thin-set or Self-Leveling Underlayment, and is installed over the top of your subfloor and beneath your flooring. The system provides a warm, even temperature across your floor, generating floor-to-ceiling radiant warmth to transform these naturally cold surfaces into warm floors. Ideal for kitchens, bathrooms or any room in your home where you would enjoy radiant warmth and comfort, the TempZone™ floor heating system is easy to install, operate and maintain.

No. You cannot cut or shorten the factory heating cable, and you cannot splice two mats together. The cable is manufactured to a fixed resistance, so trimming it changes the electrical load and voids the warranty. Measure your heatable area first and order the correct length for the space.
Was this helpful?
Never cut, shorten or splice the heating cable itself; cutting it damages the system. Only the non-heating cold lead can be shortened, as your product’s manual allows. Order the size your SmartPlan™ specifies, because unused cable can’t be cut off.
Some mats let you cut the mesh, never the cable, to turn or reposition them: TempZone™ and Environ™ Flex Rolls and Slab Heat mats. TempZone™ Easy Mats and Custom Mats are made to size and must not be shortened or cut. TempZone™ Cable has no mesh: lay all of it at the spacing on your SmartPlan™.

As you install, compare the footage markings printed on the heating cable to the reference footages on your custom SmartPlan™. If they match at each reference point, you’re on track. If the cable reading is higher, too much cable was used in the previous section; if it’s lower, you used less cable than designed.

TempZone™ Flex Rolls, Easy Mats and Shower Mats deliver 15 watts per square foot, and Custom Mats 12 to 15. TempZone™ Cable and Ruler Cable deliver 3.7 watts per linear foot, so their output depends on spacing: about 15 watts per square foot at 3 inches, 11 at 4 and 9 at 5. See TempZone Cable spacing and attachment.

Operating cost depends on your local electricity rate, the size of the heated area, and how long the system runs. A 120-watt-per-square-meter (about 11 watts per sq. ft.) system heating a 100 sq. ft. room draws roughly 1,100 watts — about C$0.16/hr per hour, or C$1.30/day for a typical 8-hour day at the current national average electricity rate. Because floor heating is usually zoned and thermostat-controlled, real-world costs are typically lower than these maximums.

Both TempZone Floor Heating Mats and Cables deliver excellent results—the choice depends on your project size, layout, experience level, and climate needs.TempZone Floor Heating Mats are pre-spaced at a fixed 3" spacing (15 watts/sq.ft.) and come in standard sizes (6–210 sq.ft.). They're ideal for:
DIY homeowners and first-time PRO installers
Straightforward rectangular rooms
Faster installation (no spacing calculations)
Smaller to medium projects
Consistent heat output across all climates
TempZone Floor Heating Cable offers complete flexibility and is preferred by experienced installers:
Adjustable spacing based on local climate conditions — you control the watt density
Colder climates (like New York): 3" spacing (15 watts/sq.ft.) for maximum heat output
Standard climates: 4" spacing (11 watts/sq.ft.) — our default recommendation
Ideal for complex layouts, odd-shaped rooms, or climate-optimized designs
The bottom line: Choose mats for simplicity, DIY projects, and standard applications. Choose cable for customization, climate optimization, complex layouts, and experienced installers. Both systems are compatible with thinset and self-leveling compound, backed by our industry-leading warranties, and supported by 24/7 expert guidance.
Pro Tip: Combining Both Systems
Many projects use a combination of both—mats for large open areas and cables for detailed work around fixtures and in tight spaces. Your free SmartPlan™ will recommend the best approach based on your room layout.

Loose TempZone Cable gives you the most coverage in a kitchen because you can steer it around islands, cabinets and appliances — up to 100% of open floor. TempZone Flex Rolls embed the cable in mesh, so they roll out much faster and deliver 15 watts per square foot, but coverage in a cut-up kitchen is slightly lower. Compare both in the Instant Quote tool.
