ThermoSlab® Heating Mats

ThermoSlab® floor heating mats provide energy-efficient radiant heat for concrete slab applications in residential and commercial spaces. Designed for installation within concrete slabs, these pre-configured mats combine the performance of ThermoSlab® heating cable with the convenience of a factory-spaced layout. The pre-attached heating cable maintains consistent spacing for uniform heat distribution while simplifying system design, installation, and power planning. Compared to loose cable systems, ThermoSlab® mats can significantly reduce installation time and ensure accurate coverage across large, open areas. Once installed, virtually any finished flooring—including tile, stone, engineered wood, luxury vinyl tile (LVT), and other compatible floor coverings—can be placed over the slab, delivering consistent, whole-room comfort and long-lasting radiant warmth.

What are ThermoSlab® Electric Concrete Floor Heating Mats?
ThermoSlab® Electric Concrete Floor Heating Mats are designed to add comfortable radiant warmth directly inside a concrete slab or foundation. The rugged heating mats can be installed in concrete or in the sand beneath a concrete slab, creating a permanent electric radiant floor heating system that works with the thermal mass of concrete to store and release heat over time.
Are ThermoSlab® Electric Concrete Floor Heating Mats safe for homes and businesses?
Yes. ThermoSlab® Electric Concrete Slab Floor Heating Mats are designed as a safe electric concrete floor heating solution for residential and commercial spaces. ThermoSoft floor heating systems are ETL listed and go through thorough development and quality control testing. ThermoSlab® Electric Concrete Floor Heating Mats use a shielded heating cable design that emits virtually zero Electro Magnetic Field (EMF).
What floor types can ThermoSlab® Electric Concrete Floor Heating Mats be used under?
ThermoSlab® Concrete Electric Floor Heating Mats are installed inside or beneath a concrete slab or concrete foundation, so they can be used with most finished floor covering materials that are approved for installation over concrete. This may include ceramic and porcelain tile, natural stone, laminate, engineered wood, vinyl, carpet, and other floor coverings approved by the flooring manufacturer for use over a heated concrete slab.
How are ThermoSlab® Electric Concrete Floor Heating Mats installed?
ThermoSlab® Electric Concrete Floor Heating Mats are installed before the concrete slab is poured. Depending on the project, the heating mats may be secured to metal mesh, rebar, or another approved layout method before the concrete is poured. ThermoSlab® Electric Concrete Floor Heating Mats are electrically wired in parallel to a compatible floor heating thermostat. Always follow the ThermoSoft Installation Manual and have final electrical connections completed by a licensed electrician.
Will ThermoSlab® Electric Concrete Floor Heating Mats add height to my floor?
No. ThermoSlab® Electric Concrete Floor Heating Mats are embedded in the concrete slab or installed beneath the slab, so they do not add height to the finished floor assembly.
How deep does the concrete need to be for ThermoSlab® Electric Concrete Floor Heating Mats?
ThermoSlab® Electric Concrete Floor Heating Mats can be installed in concrete that is 2 inches or thicker. Always confirm the project details and follow the ThermoSoft Installation Manual before installation.
What if I am not pouring a full 2 inches of new concrete?
If you are pouring less than 2 inches of new concrete, ThermoSlab® Electric Concrete Floor Heating Mats may not be the right fit for the project. In many thinner floor heating applications, ThermoTile® Electric Floor Heating Mats or ThermoTile® Electric Floor Heating Cable may be a better option. Contact ThermoSoft US experts for help choosing the right electric radiant heating system before ordering.
Can I use more than one ThermoSlab® Electric Concrete Floor Heating Mat in a room?
Yes. Many projects use multiple ThermoSlab® Electric Concrete Floor Heating Mats to cover the desired heated area. The mats are laid out together and electrically wired in parallel to the thermostat. They must not be daisy chained or extended in a series electrical connection.
Can ThermoSlab® Electric Concrete Floor Heating Mats be cut or shortened?
No. The heating cable in ThermoSlab® Electric Concrete Floor Heating Mats should never be cut, shortened, reshaped, or altered in the field. Choose the correct mat sizes and layout before installation or contact ThermoSoft’s US experts for layout assistance.
Can the cold lead wires of ThermoSlab® Electric Concrete Floor Heating Mats be shortened?
Yes. The cold lead wires do not produce heat and may be shortened, cut, or extended by a licensed electrician according to the ThermoSlab® Installation Manual and local code requirements.
What about areas not covered by ThermoSlab® Electric Concrete Floor Heating Mats?
Not every area of the slab needs to be heated. Finished flooring can be installed as normal over both heated and non-heated areas of the concrete slab. ThermoSoft US experts can help you review the layout for optimal coverage.
Can ThermoSlab® Electric Concrete Floor Heating Mats really stand up to a concrete pour?
Yes. ThermoSlab® Concrete Electric Radiant Floor Heating Mats are rugged heating mats designed specifically for new concrete slab applications. We highly recommend using an InstAlarm ® Monitor during installation. The InstAlarm ® Monitor connects to the lead wires and sounds an alert alarm if the heating cable is damaged during installation.
How many Watts per square foot do ThermoSlab® Electric Concrete Floor Heating Mats produce?
ThermoSlab® Electric Concrete Floor Heating Mats produce approximately 14 Watts per square foot when installed at standard 5-inch (on center) spacing. Actual output may vary if electric heating cable spacing is adjusted for the specific project.
How much do ThermoSlab® Electric Concrete Floor Heating Mats cost to operate?
Operating cost depends on the heated area, local electric rates, slab insulation, thermostat settings, and usage. Because the concrete mass stores and releases heat over time, ThermoSlab® Electric Concrete Floor Heating Mats may be used differently than a surface level floor heating system. For a project specific estimate, contact ThermoSoft’s US experts with the room size, slab details, and planned heating mat layout.
How warm do ThermoSlab® Electric Concrete Floor Heating Mats make the floor?
A properly installed ThermoSlab® Electric Concrete Floor Heating Mat system can typically provide a comfortable floor temperature increase above the room’s ambient temperature. In many applications, the system can provide about 10 to 15 degrees Fahrenheit of temperature difference above ambient room temperature. Actual results depend on the room, slab construction, insulation, thermostat temperature settings, floor covering, and installation conditions.
How long do ThermoSlab® Electric Concrete Floor Heating Mats last?
ThermoSlab® Electric Concrete Floor Heating Mats are very reliable; they have no moving parts and do not require regular maintenance once installed correctly and left undisturbed. The heating mats carry a 10-year warranty. Thermostats are covered separately according to the thermostat warranty. Buy with confidence.
Can ThermoSoft help with my ThermoSlab® Electric Concrete Floor Heating Mats layout?
ThermoSoft’s US experts can help confirm mat size, layout, voltage, thermostat needs, and installation approach before you order.

Combine mats of different lengths and widths as needed to fit open walkable space, avoiding areas covered by cabinets, vanities or other permanent fixtures. The mesh on the mats can be cut for repositioning however the cable cannot be shortened so avoid over-filling. Each mat will connect to the thermostat, so larger mats will reduce required connections. A sole thermostat can support 1800 watts when connected to 120V mats and 3600 watts when connected to 240V mats. Relays are available to expand coverage areas or enable usage with larger mats. DO NOT MIX VOLTAGES. Contact a knowledgeable member of our technical support team for assistance. Contact us for project assistance or help finding a local dealer/installer.

A floor heating thermostat is necessary to control your radiant heat system. Most of our floor heating thermostats are dual-voltage and include a 5ma GFCI, unlike models from online warehouse retailers. A thermostat is capable of a 15-Amp load; adding a power module or relay will increase system load capacity. Each includes a floor sensor, but a backup is recommended. Select 1 thermostat for each zone desired. Contact an expert for guidance.
