Ardex FLEXBONE Heat 240V Cable

FLEXBONE Heat cables are engineered with aluminum tubing and FEP cable insulation which provides maximum heat spreading on stone or tile floor while minimizing the amount of wattage used. The cables work with the FLEXBONE In-Floor Heating Membrane to provide radiant heat in wet or dry areas with tile or stone flooring. The FLEXBONE floor heating cable system is the only system that can work with wood, laminate vinyl tile or carpet flooring when using K 60 ARDITEX Rapid Setting Latex Smoothing and Leveling Compound. ​​​​​​​​​​


Features

  • Cold/Hot junction self-contained within the cable; no bulky connection box to cut and bury
  • Heating cable must be spaced so that at least two crossbone patterns are between the cables (approx. 3.88” / 9.8 cm) - see image 3
  • Can also be installed in a "comfort" setup with at least 3 crossbone patterns between cables
  • Heating cables may not cross, overlap or touch each other
  • Provided with 2 floor sensors - one with heat cable, one with thermostat
  • 11% less wattage required per sq. ft.
  • Less cable required per sq. ft.
  • Heat resistant up to 401°F (205°C)
  • Aluminum tubing guarantees ZERO electromagnetic fields
  • All cables are the same diameter allowing a secure fit in the membrane no matter the length
  • Must use SK-175 Waterproofing Seam Tape on seams between adjacent mats
  • Ideal for large-format tile and stone installations

Questions & Answers
3 questions

When would you use the 240V vs 120V cable?

This would be determine by the available power on site and the desired size/length of heat cable installation.

Can 1 thermostat run two cables as long as they don't exceed 15 amps?

It is possible to run a single thermostat with multiple wires.

Thermostat (A) is connected to wire 1 (B) as normal. Thermostat (A) is also connected to power module (C). (A) and (C) need their own dedicated circuits In the electrical panel. Wire 2 (D) is then connected to Power Module (C).

The thermostat is the brains of the system while the power module is a worker bee doing what it is told. The thermostat would then control all connected power modules (C) and its own single wire (B).

Is there a way to extend the cold lead? The thermostat is about 12' from heated floor.

Yes, you can extend the cold lead using either a shrink wrap splice kit, or junction box. Use #14 shielded cable.
