For warm tile floors, choose an electric heating kit sized to the uncovered floor area, or pair a compatible heating cable with an underlayment designed for radiant heat. The LuxHeat 20-square-foot mat is best for smaller spaces, while the 40- and 150-square-foot LuxHeat kits suit larger areas and include heating cable, thermostat, and membrane. Schluter Ditra-Heat and Clyro are underlayments, not complete heating systems; they do not include a heater or thermostat.

LuxHeat 20 Sq. Ft. Heated Floor Mat Kit
Best for: A smaller bathroom, kitchen section, or other tile area with approximately 20 square feet of usable coverage. This kit includes a 120-volt self-adhesive heating mat, a programmable thermostat with floor sensor and built-in GFCI, and a cable monitor or alarm.
The mat has heating cable spaced at three-inch intervals. Its mesh can be cut, turned, flipped, or rotated to fit a floor layout, and adhesive on the mesh and tape helps hold it in place. The listed features say the system can be installed under tile, laminate, and other flooring, with the heating wires embedded in self-leveling underlayment, thinset, or mortar.
Choose this kit if a pre-spaced mat and included controls are a better fit than laying loose cable. The manufacturer lists a 25-year limited warranty. A key limitation is that the red heating wire must not be cut or shortened; plan the layout around the fixed wire length and actual open floor area.
LuxHeat 40 Sq. Ft. Cable Heating System
Best for: A medium-sized tile installation where a loose cable and uncoupling membrane offer more layout flexibility than a pre-spaced mat. The 120-volt kit includes 40 square feet of heating cable, a 50-square-foot Prova Flex-Heat membrane, a programmable touchscreen thermostat, a floor sensor, and an alarm.
The included thermostat has dual air-and-floor sensing, a seven-day schedule with four events, power logging, and a child lock. The membrane is described as providing uncoupling, waterproofing, crack prevention, and load support. These features make the kit a bundled option for buyers who want heating components and tile underlayment together.
Choose this system if the heated footprint is close to the cable’s rated coverage and the project calls for a membrane beneath tile. The cable must be covered with self-leveler or thinset. Do not cut or shorten the heating wire, and allow for unheated areas beneath fixed objects when calculating coverage.
LuxHeat 150 Sq. Ft. Wi-Fi Heating System
Best for: A large room or broad tile area that needs up to 150 square feet of heating cable. The package includes 120-volt cable, a 170-square-foot Prova Flex-Heat membrane, an UWG5 touchscreen Wi-Fi thermostat, a floor sensor, an alarm, and a wood float for membrane installation.
The thermostat is described as offering app connection, voice control, dual air-and-floor sensing, self-learning, and up to 10 schedules. It also includes Class A GFCI protection. The membrane is intended to provide a base for tile and support uncoupling, waterproofing, crack prevention, and load distribution.
Choose this kit when the required heated area is larger and Wi-Fi scheduling is useful. Its cable coverage is 150 square feet, not the membrane’s 170-square-foot area; those figures describe different components. The heating wire must be covered with self-leveler or thinset and must not be cut or shortened. Confirm the room’s usable heated area and electrical requirements before selection.
Schluter Ditra-Heat Electric Heating Membrane
Best for: Buyers comparing an underlayment for a tile project who plan to select the heating cable and controls separately. This product is a polypropylene membrane with a listed thickness of one-quarter inch. Its column-like mortar structures are designed to distribute load and support floor stability.
The listed applications include ceramic and porcelain tile, natural stone, and other resilient flooring materials. Its role is as a membrane or underlayment; the provided product information does not say that a heating cable, thermostat, or floor sensor is included. It should not be treated as a complete in-floor heating kit.
Choose it when the underlayment itself is the item being sourced and the rest of the heating system will be planned separately. The available features provide no coverage dimensions, included electrical components, or installation instructions, so verify those details for the specific product and project before buying.
Clyro 54 Sq. Ft. Heating Cable Membrane
Best for: A tile project that needs a membrane designed to hold separately purchased heating cables. The roll covers 54 square feet and is approximately one-quarter inch thick. Its listed materials are high-density polyethylene and polypropylene.
The product description says the membrane is suitable for bathrooms, shower areas, and kitchens, and describes it as waterproof and moisture- and crack-resistant. Open channels beneath its fabric layer are intended to let moisture dissipate. The membrane can be cut to fit the space, and its design allows heating cable to be positioned where warmth is needed.
Choose this option if a 54-square-foot underlayment roll fits the project and the heating cable will be sourced separately. The listing does not describe this as a complete system or specify an included thermostat, sensor, or cable. Check the cable manufacturer’s installation requirements and confirm that the combined components are appropriate for the intended floor assembly.
Buying Guide: How To Choose In-Floor Tile Heat
Do you need a complete heating kit or just a membrane?
A complete electric floor-heating kit should identify the heating element and its coverage, and may include a thermostat, floor sensor, and installation components. The LuxHeat products here include heating cable or a heating mat and controls. The Schluter and Clyro products are membranes; their provided features do not list a heater or thermostat.
This distinction matters when comparing product coverage. A membrane’s square footage describes the underlayment area, while a cable or mat’s square footage describes its heating coverage. Those measurements are not interchangeable. If a membrane covers more area than the heating element, the extra membrane does not create additional heated floor.
How much heated floor area should you plan for?
Measure the floor area where heating can actually be installed, rather than using the room’s full footprint automatically. Fixed cabinets, built-in fixtures, and other areas where heating elements cannot be placed may reduce the usable area. Follow the product’s installation instructions and account for required clearances before choosing a kit.
Among these options, the 20-square-foot LuxHeat mat is the smallest complete kit, the 40-square-foot LuxHeat system is a middle-size cable kit, and the 150-square-foot LuxHeat system covers the largest listed heated area. Match the heated footprint to the project; do not select a kit only because its included membrane has a larger area.
Should you choose a mat or loose heating cable?
A pre-spaced mat can simplify layout across a regular open floor. The 20-square-foot LuxHeat mat has three-inch-spaced cable and can be turned or rotated to follow a layout. Its mesh can be adapted, but the heater wire itself must not be cut or shortened.
A cable-and-membrane kit can offer more flexibility for irregular floor shapes. The 40- and 150-square-foot LuxHeat systems pair cable with an uncoupling membrane. The heating cable still has a fixed length and must be placed according to its instructions. A flexible layout does not mean the heating wire can be cut.
Which thermostat features matter?
Check whether a thermostat is included and whether its listed functions suit the way the room will be used. The 20- and 40-square-foot LuxHeat kits list programmable thermostats with floor sensors and GFCI protection. The 40-square-foot kit lists dual sensing and a seven-day, four-event schedule. The 150-square-foot kit adds Wi-Fi, app connection, voice control, and up to 10 schedules.
Control features differ across kits, so compare the stated functions rather than assuming all thermostats are alike. Electrical requirements also matter. The listed LuxHeat kits are 120-volt systems, and the thermostat specifications provided include a 15-amp rating. Have a qualified professional confirm the installation’s electrical suitability where needed.
What should you verify before installing heat under tile?
Confirm that the heating system, membrane, mortar, and tile are suitable for the planned floor assembly. Follow the specific manufacturers’ instructions for substrate preparation, cable placement, embedding, and testing. The LuxHeat cable-system features state that heating wires must be covered with self-leveler or thinset. The 20-square-foot mat instructions similarly specify embedding the wires in an approved layer.
Do not cut or shorten heating wire. Plan the cable route before installation and use the included alarm or monitoring components as directed. For a membrane-only purchase, independently verify the heating cable’s compatibility and whether additional waterproofing or installation materials are required; the product feature list alone does not establish those details.
How should waterproofing and crack protection factor into the choice?
Underlayment descriptions can include moisture management, uncoupling, and load support, but these terms do not make every membrane identical or guarantee a specific result in every installation. The LuxHeat kits include Prova Flex-Heat membrane, which is described as providing waterproofing, crack prevention, and load support. Clyro describes its membrane as waterproof and moisture- and crack-resistant.
The Schluter product information provided emphasizes load distribution and floor stability. It does not provide the same listed claims or coverage details as the other membranes. Compare the documentation for the exact product and intended use, especially in wet areas, and follow the complete installation system requirements.
Frequently Asked Questions
Can a floor-heating membrane heat tile by itself?
No. A membrane is an underlayment component, not a heating element. The Schluter and Clyro products listed here do not include a heater in their provided features. A compatible cable or mat and appropriate controls are needed for electric radiant heat.
Can electric heating wire be cut to fit a room?
The LuxHeat cable and mat features say not to cut or shorten the heating wire. Adjust the layout around the fixed wire length and follow the product instructions. The mat mesh may be adjusted as described, but that does not mean its red heater wire can be cut.
What does the square-foot rating on a heating kit mean?
For the LuxHeat systems, the listed 20-, 40-, or 150-square-foot figure refers to the mat or heating-cable coverage. It is different from the included membrane coverage. Measure usable floor area and compare it with the heating element’s coverage before choosing.
Which listed system includes Wi-Fi control?
The LuxHeat 150-square-foot system includes an UWG5 Wi-Fi programmable thermostat. Its listed features include app connection, voice control, dual sensing, and up to 10 schedules. The other LuxHeat products described here list programmable thermostats but not those Wi-Fi features.
Can these systems be installed under flooring other than tile?
The 20-square-foot LuxHeat mat features list tile, laminate, and other flooring. The 40- and 150-square-foot kits are presented for tile with their included membrane. Confirm flooring suitability and installation requirements for the exact product before using it with a different floor finish.
