- Connect to 120/208/240 supply voltages
- Factory attached 20 ft. cold lead wire for a flexible connection to thermostat
Will you be laying down fresh concrete slab for an indoor space? This is the perfect time to install a slab heating system! ThermoSlab mats add value and comfort to your project without putting strain on your schedule. Simply roll out mats with pre-spaced cables eliminating time required for manual uniform placement. Enjoy the luxury of heated flooring in any space with concrete slab such as your garage, basement, or sunroom. Easily install any flooring type on your slab with an embedded electric heating system that provides gentle warmth throughout your home. Lower your heating costs by charging your slab with radiant heat during off-peak electricity pricing and enjoy steady heat throughout the day. Speak to our knowledgeable U.S. based technical support team to guide you from the initial planning stage through project completion.
Slab Heating Mats
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.

Thermostats & Critical Components
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.
Avoid future replacement headaches (15'). Include 1 per thermostat.
2-Gang electrical box, conduit & connectors. Include 1 per thermostat.

How To Install ThermoSlab Heating Cable
This overview does not substitute for a full reading of the Installation Manual.
The below steps will take you from beginning to end simply, but please refer to the full Installation Guidelines or call us to go over a more detailed installation plan.
ThermoSlab Mats are an easy way to add heat to concrete while laying down a fresh slab. Easily install any flooring type on your finished slab if desired.
Before beginning your installation:
- Plan your order for area coverage.
- Consider in your plan the need to stay 12 inches off from fixtures such as, but not limited to, drains, pipes, or electrical conduits.
- Measure the resistance of the heating cables in the mat before beginning installation, as well as at multiple points during installation.
1Make sure you have the right amount of material.
- Follow heating mats spacing from walls according to the manual.
- Heating elements should be in areas where you can walk, stand, or want to heat. See your manual for areas to avoid heating.
- Contact technical support if you have any questions prior to your installation.
2Prepare conduits and electrical boxes for installation later.
- Complete electrical rough-in
- This step may be completed after mats are laid but is more difficult to accomplish later as location of thermostat may change orientation of heating system
3Begin laying out the heating mats. Ensure that the mat will set at least 2 inches below the surface of the concrete or combination of sand and concrete.
- Carefully cut and reposition mesh as needed to fit mats to desired room shape without cutting the heating cable.
- Position the mat with at least 12 inches of lead wire embedded in the cement.
4Install the sensors.
- Position sensor evenly between 2 heating cables.
- Do not cross the heating cable.
- It is highly recommended to install a backup sensor.
5Pour the concrete
- Take necessary care to avoid damage to the heating system with tools or machinery during pour.
- Test the resistance of all cables while concrete is still wet.
6Wait until the concrete is fully cured before powering on the system.
- This is roughly a 30 day process, consult with the specifications of the concrete for a specific length of time.
