Tips for a Successful Installation
- Never cut or overlap the red heating wires
- Confirm the ohm resistance between the black and white cold lead wires is correct throughout the installation
- Embed system in a polymer modified cement based mortar
- If installing on a concrete slab we recommend using some type of insulation to avoid heat loss through the concrete such as Cerazorb synthetic cork
- Keep heating wire 6”-8” away from wax ring of toilet
- HEATING CABLES: When using cables with Schluter-DITRA-HEAT or Prodeso Heat Membrane System, space wires alternating 3 pegs/2 pegs for an average of 3” spacing.
MATERIALS REQUIRED FOR INSTALLATION:
- Floor Sensing Thermostat (available for purchase with floor heating system)
- UL Listed electrical box 4x4 with single gang "mud ring" cover
- Flexible or rigid UL Listed conduit
- 12-gauge or 14-gauge electrical wiring, consult electrical code
- Wire nuts (included with thermostat purchase)
The Installation Monitor included with your purchase screams a warning if the heating element is cut or damaged during installation.
The floor heating system needs to be GFCI Protected. You can do this one of three ways.
- Use a GFCI protected circuit breaker
- Have the system tapped off the protected side of a GFCI outlet
- Use a thermostat with the GFCI built into it
When installing on a concrete slab we recommend using some type of insulation to avoid heat loss through the concrete such as Cerazorb synthetic cork underlayment https://www.warmingsystems.com/cerazorb-thermal-break-underlayment-2-x-4-use-when-installing-on-concrete-slab/.
- Test the floor heating system.
- Check Thermostat and Electrical Requirements making sure the 10' cold lead(s) at the end of the system reach the thermostat.
- Unspool the cable, spacing it 3" apart on the floor and securing it with the included cable guides. Unroll the mat and use the mat turn techniques provided in the installation manual to properly cover the area you want to heat. Use double- sided tape on mat to hold it in place.
- Connect the power leads and thermostat sensor to the thermostat. The sensor wire should be located in between two heating elements, at least 6" from the edge of the heated area.
- The heating system must be embedded in 1/4" to 1/2" thick polymer modified cement based mortar. The heating system should be installed on concrete or concrete backer board.
- Install Floor Covering
- Terminate all electrical connections.

Use a polymer modified cement based mortar.
Yes. We recommend using some type of insualtion to avoid heat loss through the concrete. We sell a synthetic cork underlayment called Cerazorb that does this https://www.warmingsystems.com/cerazorb-thermal-break-underlayment-2-x-4/.
We recommend installing 4" from the wall since the heat radiates no more that 2" in either direction from the cable.
The OJ Electronics thermostats and aube by Honeywell model TH115-AF-GA thermostat are GFCI protected. The aube by Honeywell thermostats TH115-AF-120S and TH115-AF-240S are not GFCI protected. If you use these thermostats you need to have a GFCI protected circuit breaker.
4" square electrical box with a single gang mud ring that's located within reach of the 10' cold lead.
No. The electric floor warming systems manufactured by Warming Systems Inc. are designed for interior floor applications, supplying 12 watts/square foot. They cannot be used for exterior snow melt or ceiling heating applications.
