Floor Heating Cables
Maximum Flexibility for Custom Installations
Floor heating cables offer the ultimate flexibility for custom installations. Unlike pre-spaced mats, cables can be routed around any obstacle and adjusted for precise heat output.
Ideal for irregular room shapes, complex layouts, and professional installers who demand maximum control. Our TempZone™ cables work with tile, stone, marble, and hardwood flooring.
Whether you're heating a curved bathroom, an L-shaped kitchen, or a room with many fixtures, floor heating cable gives you the freedom to create the perfect layout.
Why Choose Floor Heating Cable?
Maximum Flexibility
Route cable around any obstacle—toilets, vanities, islands, columns. Perfect for irregular room shapes and complex layouts.
Adjustable Heat Output
Control heat intensity by adjusting cable spacing. Closer spacing = more heat per square foot for cold zones.
Any Room Shape
L-shaped rooms, curved walls, bay windows—cable adapts to layouts that mats simply can't cover efficiently.
Professional Preferred
Experienced installers often prefer cable for its precision and ability to maximize heated area in complex spaces.
Full Coverage
Get closer to walls and fixtures than pre-spaced mats allow. Heat every usable square foot of floor space.
Safe & Certified
All our floor heating cables are UL/cUL listed and backed by our 25-year No-Nonsense Warranty.
Cost-Effective
Cables often cost less than mats for the same square footage, especially in larger installations.
30+ Year Lifespan
Quality construction means your floor heating cable will provide reliable warmth for decades.
Floor Heating Cable vs Mat: Which Should You Choose?
Floor Heating Cables
Best for irregular rooms, custom layouts, or when you need maximum flexibility around obstacles.
- Maximum layout flexibility
- Works around any obstacle
- Adjustable heat output (via spacing)
- Preferred by professional installers
Heated Floor Mats
Best for rectangular rooms with minimal obstacles. Pre-spaced heating elements make installation faster and easier.

"Most homeowners are surprised how affordable radiant floor heating is to operate—often just pennies a day for a bathroom. It's the kind of everyday luxury that pays for itself in comfort!"
— Rae RadiantAdjusting Heat Output with Cable Spacing
Unlike mats with fixed spacing, cables let you control heat intensity by adjusting the spacing between runs:
3" spacing
15W/sq ft — maximum heat for cold rooms
3.5" spacing
12W/sq ft — ideal for most bathrooms
4" spacing
10W/sq ft — supplemental heat
5" spacing
9W/sq ft — gentle warmth
Slab Heat Cables for Concrete
Heavy-duty heating cables designed for new concrete slab construction. With 15–20 watts per square foot output, Slab Heat cables provide powerful warmth that penetrates through thick concrete—ideal for basements, garages, sunrooms, and additions. Cable is embedded 2–3" from the finished surface during the pour.
Spacing Guidelines
- 3" spacing — Bare, polished, or stamped concrete
- 5" spacing — When adding floor covering (tile, wood)
Curing Time
Allow 7 days minimum for concrete to cure before powering on the heating system.
Insulation Tip
For new construction, install rigid foam boards (XPS/EPS) with a vapor barrier under the slab—never over, as that would trap the heat.
Warmth for Concrete Floors
With concrete heating cables, you can design your concrete floors to be as warm and functional as they are attractive. Radiant heating cables offer maximum flexibility for installation under concrete slab floors.
Features
- Embedded directly into new concrete pours
- Ideal for basements, garages, and sunrooms
- Long-lasting radiant heat built into the slab
- 10 Year Warranty
- 15-20 Watts Per Sq. Ft

Floor Heating Cable FAQs
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 Radiant 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.
Electric floor heating is surprisingly affordable to operate, especially when used with a programmable thermostat. Operating costs depend on several factors:
Key Cost Factors:
- Room size – Larger heated areas use more power
- Flooring type – Tile heats efficiently; carpet requires more energy
- Insulation quality – Well-insulated rooms retain heat better
- Usage patterns – Programmable thermostats significantly reduce costs
- Local electricity rates – Typically $0.10-$0.20 per kWh
- Climate zone – Colder regions require more heating
Typical Operating Costs:
For a standard 100 sq. ft. bathroom with tile flooring:
- Per hour of operation: $0.15-$0.30
- Daily cost (4-6 hours): $0.60-$1.80
- Monthly cost (winter): $18-$54
- Annual cost: $150-$400 (varies by climate)
Cost-Saving Strategies:
- Programmable thermostats – Heat only when rooms are in use
- Smart thermostats – Learn your schedule and optimize automatically
- Zoned heating – Heat individual rooms instead of whole-house systems
- Supplemental heating – Use radiant heat to reduce central heating needs
Many customers find floor heating costs comparable to or less than running space heaters, with the added benefits of comfort, safety, and increased home value. Use our cost calculator for a personalized estimate based on your room size and usage.
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.
