Two Ways to Install Floor Heating Cable
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.

We've Got Your Back: A Backup Floor Sensor
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.

TempZone™ Floor Heating Cable FAQs
Showing all 5 questions
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.
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.
Many homeowners successfully install electric floor heating as a DIY project, especially with a detailed SmartPlan™. However, the level of professional help needed depends on your skills and project scope:
DIY-Friendly Aspects:
- Layout and installation of heating mats or cables following your SmartPlan™
- Securing cables to subfloor using installation strips or adhesive
- Testing resistance with a multimeter (we provide testing logs)
- Tile or flooring installation if you're experienced with that trade
You'll Need a Licensed Electrician For:
- Thermostat wiring and connection to your electrical panel
- GFCI protection installation (required by code)
- Dedicated circuit installation if needed
- Code compliance and final inspection
Consider Professional Installation For:
- Large or complex room layouts
- Multiple rooms or whole-home installations
- Time-sensitive projects
- Commercial applications
Your SmartPlan™ includes detailed installation instructions that make the mechanical installation straightforward. Our 24/7 tech support is available to answer questions during your project, whether you're DIY or working with a contractor.
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 $0.18/hr per hour, or $1.43/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
- Warmer climates (like California): 5" spacing (9 watts/sq.ft.) for efficient, moderate heating
- Works in any room shape or size
- 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.
