Electric Heated Floors – Radiant Floor Heating Systems
Heated Floors for Every Room — Under Any Flooring Type
Heated floors—also called radiant floor heating—warm a room from the floor up by running thin electric heating cables or pre-spaced mats beneath your flooring, with no fans, ducts, or circulating dust. They're an energy-efficient way to add lasting warmth throughout your home—from bathrooms and kitchens to bedrooms, basements, and sunrooms that can be tricky to keep comfortable. WarmlyYours electric systems install easily under heated tile floor systems, vinyl, laminate, and hardwood, with free design support on every project.

What's in a Radiant Floor Heating System?
A complete electric floor heating system is built from a few simple parts that work together to deliver safe, even warmth.
Heating element
Choose a pre-spaced heated floor mat for fast installs or a loose heating cable for custom layouts—on a shared or dedicated circuit, depending on the job size.
Thermostat
Line-voltage 120/240 V with built-in Class A GFCI and floor sensor. Pick nSpire Touch, nTrust 2.0, or nJoy WiFi to match the room.
Floor sensor
A probe embedded in the floor that reports actual floor temperature back to the thermostat. Every WarmlyYours system ships with two sensors—one to install and one as a built-in spare.
Insulating underlayment (optional)
ThermalSheet under concrete slabs and unheated spaces blocks downward heat loss, shortens warm-up time, and lowers operating cost over the system's life.
Uncoupling membrane (optional)
Paired with cable systems under tile and stone, a Prodeso membrane absorbs minor substrate movement so the finished floor stays crack-free over the heating cable.
Circuit Check (essential install aid)
A pocket-size continuity monitor that clips to the heating element and beeps the moment a cable is nicked—so damage is caught and fixed before it's buried under thinset.
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.

Our electric radiant floor heating systems have withstood rigorous safety testing and earned the UL listing. They produce much less EMF than common household appliances like your TV or vacuum cleaner. The EPRI (Electric Power Research Institute) tests all electrical devices and publishes the data. Many common household appliances are tested at a distance of 6 inches. The test results indicate that on average, the EMF emitted for the following appliances, measured in Milligauss (mG) units, is:
Vacuum Cleaner: 300 mG
Microwave: 200 mG
Portable Heater: 100 mG
Dishwasher: 20 mG
Washing Machine: 20 mG
WarmlyYours TempZone™ (Twin): 1.8 mG
WarmlyYours’ TempZone™ product is most commonly installed under tile, stone, and marble flooring, but can also be installed under many other popular floor covering options such as hardwood, vinyl and linoleum. We also have our Environ system, which is an electric floor heating product as well and is specially designed for installation under carpet (in the U.S. only), laminate and floating wood. WarmlyYours can accommodate any flooring type with either of the electric radiant floor heating products that we offer. If your flooring type isn't listed here, just give us a call at (800) 875-5285 and we will be happy to discuss it with you.
The answer to this question will depend on a whole host of variables related to electric floor heating, including, but not limited to, the run time (for supplemental heating, we usually recommend between 4-8 hours per day), the electric radiant floor heating system you're using, the total square footage, and your local electrical cost. Typically, the cost is just a few cents a day.
To figure out how much electric floor heating might cost to run for you, make sure to use our interactive Operating Cost Calculator.
Yes, in most cases, an electric floor heating system can be effective as a primary heat source. However, our TempZone™ and Environ™ systems are most commonly used as a secondary heat source, providing floor-to-ceiling radiant heat to any room in your home where you desire more warmth and comfort.
If you are considering electric floor heating for an addition to your home, such as a sunroom where you have no other source of heat, WarmlyYours offers an innovative online tool which calculates approximate heat loss. This tool can help you to determine if a WarmlyYours’ electric radiant floor heating system will provide your desired comfort temperature throughout the year. You can access the Heat Loss Calculator or you can call us at (800) 875-5285 and a Customer Service Representative will make the calculation for you.
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.
Typically, electric floor heating is used as a supplemental heat source but in some cases, it can be used as a primary heat source. Electric floor heating is more energy efficient, less prone to spreading dust and allergens, and easier to control from room to room. Air-based heating systems can be used for both heating and cooling and can be a good way to control air quality in the home with regular maintenance.
For a more in-depth answer to this question, check out Your ‘Cheat Sheet’ for Radiant Heat vs. Forced Air.
The temperature of your floor can range anywhere between 75°F to 95°F. The floor's actual temperature will depend on a number of factors including the amount of heat loss that the room experiences as well as the room’s configuration. For instance, the warmth contained in a two story entry way would likely be less than that of a smaller, more enclosed area such as a bathroom. In a bathroom that is located on the second floor of your home or over another floor in your home that is typically heated, the temperature of your heated floor should easily reach a comfortable temperature of 85 degrees Fahrenheit, if the electric floor heating system is installed correctly. For the heat loss calculation for your specific room, you can access the Heat Loss Calculator or you can call us at (800) 875-5285 and a Customer Service Representative will make the calculation for you.
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.
Yes, radiant floor heating can be a primary heat source if its heat output exceeds the room's heat loss. For best results, we recommend using a 15-watt system, covering at least 80% of the floor, and ensuring the space is well-insulated. Use our Heat Loss Calculator to verify your specific needs.
Yes, radiant floor heating can be used as a primary heat source in well-insulated homes, particularly in moderate climates. However, most North American homes use it as supplemental heating to enhance comfort and reduce reliance on forced-air systems.For primary heating, you need:
- Proper insulation (walls, windows, attic)
- Adequate watt density (typically 15 watts/sq.ft. or higher)
- Coverage across 80%+ of floor area
- Climate-appropriate system design
Not sure if your home qualifies? Use our free Heat Loss Calculator to determine if radiant floor heating can serve as your primary heat source. This tool calculates your room's heat requirements based on insulation, climate, and construction details.WarmlyYours also offers free consultation with our engineering team to assess whether your home is suitable for primary heating. Our 24/7 support and 26 years of experience across 300,000+ installations ensure you get the right system for your needs.
No, radiant floor heating cannot be installed under existing floors without removing them first. The heating cables or mats must be embedded in thinset or self-leveling compound directly above the subfloor and below the finished flooring material.
However, installation during a remodel or new construction is straightforward. WarmlyYours systems are just 1/8" thick and compatible with tile, stone, laminate, engineered hardwood, nailed hardwood, luxury vinyl plank (LVP), concrete and carpet. Our 24/7 support team and free custom floor plans make installation planning easy for both DIYers and professionals.
It depends on your flooring type and heating system. For electric radiant floor heating, underlayment is often beneficial but not always required.When underlayment is recommended:
- Floating floors (laminate, engineered hardwood, LVP): Use ThermalSheet, WarmlyYours' insulating underlayment, to direct heat upward and improve efficiency.
- Cold subfloors (concrete, basements): Insulating underlayment prevents heat loss downward.
When underlayment is not needed:
- Tile and stone installations: Heating cables/mats are embedded directly in thinset or self-leveling compound—no underlayment required.
- Glue-down LVP over concrete: System can be installed in self-leveling compound without additional underlayment.
Important note: WarmlyYours currently offers ThermalSheet as our recommended underlayment solution. While CeraZorb and cork underlayment were previously available and may still be found in older installations, ThermalSheet is now our preferred product for optimal performance and compatibility.Our free SmartPlan service includes underlayment recommendations tailored to your specific flooring and subfloor. With over 600,000 custom floor plans created, we ensure you get the right system configuration.
Yes. Electric floor heating should run on its own dedicated, non-GFCI circuit — the thermostat provides the required GFCI protection. A dedicated circuit prevents nuisance trips and ensures the system gets the amperage it needs. Large areas can use a thermostat paired with power modules in 15-amp increments.
Yes. Radiant floor heating is a luxury feature that appeals to buyers by offering premium comfort and energy efficiency. It is often highlighted in MLS descriptions as a premium amenity, increasing perceived home value and appealing to luxury buyers who want move-in-ready comfort without radiators or baseboards.

No. Electric radiant floor heating systems have no moving parts and require zero regular maintenance once installed. Unlike forced-air systems that need annual filter changes and duct cleaning, floor heating provides worry-free comfort for decades, which significantly enhances its long-term return on investment.
Electric systems are easier to install, require no maintenance, and are perfect for remodeling. Hydronic systems have lower operating costs but significantly higher upfront investment and maintenance requirements. While hydronic is common in new whole-home construction, electric is the preferred choice for individual rooms like bathrooms and kitchens.
An underfloor heating system works by running electric heating cables or mats beneath your floor surface, connected to a thermostat. When activated, the cables heat up and transfer warmth upward through the floor into the room — a process called radiant heat transfer. Unlike forced-air systems that heat the air at ceiling level, underfloor heating warms objects and people directly, creating even, comfortable warmth from the floor up. Most electric underfloor heating systems reach target temperature in 30–60 minutes.
In a typical bathroom with tile or stone flooring, radiant floor heating takes about 30 to 45 minutes to reach your desired temperature. Using a programmable thermostat allows you to schedule the heat to come on before you wake up, ensuring a warm floor for your morning routine.
WarmlyYours radiant floor heating systems last 25-40+ years with proper installation and minimal maintenance. Our heating cables and mats are designed for durability and backed by industry-leading warranties. With no moving parts and corrosion-resistant materials, these systems outlast traditional HVAC equipment, which typically lasts 15-20 years. Over 300,000 installations since 1999 demonstrate long-term reliability.
Radiant floor heating typically takes 30-60 minutes to warm up, depending on floor type, insulation, and room size. Tile and stone floors heat faster (30-45 minutes), while thicker materials like hardwood may take 45-60 minutes.
For optimal efficiency, use a programmable thermostat to schedule heating before you wake up or arrive home. Once warm, the system maintains temperature efficiently. WarmlyYours thermostats include smart scheduling features and floor temperature sensors for precise control. WarmlyYours provides a backup sensor in every order.
For a typical 50-square-foot bathroom, a complete electric underfloor heating system usually costs between $500 and $1,000 for materials, including the heating element, thermostat, and (if needed) membrane/insulating underlayment. Operating costs are remarkably low, often averaging just $0.10 to $0.25 per day depending on your local electricity rates and usage habits.

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.
A complete electric floor heating system consists of two essential components: the heating element (either a pre-spaced mat or loose cable) and a specialized thermostat. But most systems will also incorporate a floor sensor to monitor temperature. Cable-based systems may also use an uncoupling membrane for tile protection. If you're installing over a cement slab or a poorly insulated space, you may also want to include thermal insulation to prevent heat loss. Together, these parts ensure safe, efficient, and consistent warmth throughout your room.
There are two main types: electric and hydronic. Electric systems use cables or mats and are ideal for retrofits and single rooms due to their low installation cost and zero maintenance. Hydronic systems circulate hot water through tubing and are typically reserved for whole-home new construction projects involving a boiler.
Spacing sets heat output. Use 3-inch spacing (about 15 watts per square foot) for primary heat, concrete slabs, and cold-climate rooms. Use 4-inch for standard comfort in moderate climates, and 5-inch (about 9 watts per square foot) for supplemental warmth on floors that are already warm.
To safely clean grout lines without damaging radiant heating wires, avoid using metal blades or utility knives. Instead, use a wooden dowel or plastic tool to remove excess thinset while it is still wet. If the thinset has hardened, proceed with extreme caution using non-metallic tools to prevent nicks or cuts to the underlying heating system.
Operating costs depend on your local electricity rate and system usage. For example, heating a 35-square-foot bathroom for 8 hours a day costs approximately $0.09/hr. To calculate the exact operating cost for your specific project and local utility rates, use our online

— Rae RadiantThe best rooms for radiant floor heating are:
- Bathrooms (most popular—eliminates cold tile)
- Kitchens (comfort during meal prep)
- Basements (solves cold concrete floors)
- Entryways/Mudrooms (melts dragged in snow, dries boots)
- Sunrooms/Three-Season Rooms (extends usability)
- Master Bedrooms (luxury comfort)
Radiant heating works in any room, but it's most valued where you walk barefoot or spend time standing. With over 300,000 installations, WarmlyYours has heated every room type—from small bathrooms (14 sq.ft.) to large open-concept spaces (200+ sq.ft.). Our free SmartPlan service designs custom layouts for any room configuration.
There are two main categories of heated floor systems: electric and hydronic. Electric floor heating systems use resistance cables or mats powered by your home's electrical panel — they're easier to install, require no boiler, and are ideal for single-room or multi-room retrofits. Hydronic systems circulate hot water through tubing and require a boiler, which means they're generally better suited to whole-home new construction. WarmlyYours specializes in electric floor heating systems, which cost significantly less to install and require zero maintenance.
Most competitors provide only 12 watts per square foot, which is often insufficient for primary heating in cold climates. WarmlyYours TempZone™ systems deliver 15 watts per square foot—a 25% increase in power. This higher output allows for faster heat-up times and provides enough thermal energy to overcome room heat loss, making it a more reliable primary heat source.
