Schluter®-DITRA-HEAT-E-HK

Electric radiant floor heating cables used with DITRA-HEAT membrane

Schluter®-DITRA-HEAT-E-HK are twisted pair heating cables designed for integration with the DITRA-HEAT uncoupling membrane in interior floor warming applications.
  • Cables snap into the membrane; clips and fasteners are not required
  • No self-levelers required to encapsulate the cables; installation time significantly reduced
  • No return to thermostat required
  • Produces virtually zero electromagnetic fields
  • 120 V and 240 V options available in a variety of lengths
  • Provides electric floor warming for use beneath tile, stone, or other resilient floor coverings (e.g. LVT)

  • Note: Two floor temperature sensors are provided with the heating cables. These can be installed at the same time as the cable.

  IMPORTANT Ordering Information for Schluter®-DITRA-HEAT Cables

  • Do not purchase a heating cable that is the same size as the area to be tiled; you will be left with too much heating cable!
  • Very important: Never CUT or modify the heating cable in any way. This would change the cable resistance, will cause damage to the cable, and could cause cable overheating.
  • A cable spacing of 3 studs is standard.
  • Cable may also be spaced at continuously alternating 3 stud – 2 stud intervals in isolated areas or over the entire floor. This practice may be desirable to increase heat output (e.g., over uninsulated on or below grade concrete subfloors) or to consume more cable length in a given area (e.g., when using the standard 3 stud spacing doesn’t allow the selected cable to fit the floor area and respect minimum spacing requirements from walls, partitions, etc.)
  • A cable spacing of 4 studs is not recommended, as it can produce inconsistent floor surface temperatures.
  • Minimum spacing from walls, partitions, and fixed cabinets is 2" (50 mm).
  • Minimum spacing from other heat sources (baseboard heaters, other fixed heating devices, fireplaces, etc.) is 8" (200 mm).
  • Minimum spacing from any plumbing drain and forced air heating duct  is 4" (100 mm).
  • Minimum spacing from centerline of toilet drains is 7" (180 mm).
  • NEVER install the heating cable under vanities with no air space beneath, bathtub platforms, free standing bathtubs with no air space beneath, kitchen cabinets and islands, any other fixtures in storage or clothing closets. Excessive heat will build up in these confined spaces and may cause cable overheating.
  • NEVER install the heating cable under or through a wall, partition, or through a floor.
  • NEVER install the factory splice (i.e., black plastic junction between the cold lead and gray heating cable) in the wall. This will cause overheating, system failure, and could cause damage. This splice must be installed entirely under the floor covering, as shown in the heating cable installation instructions.
  • It is helpful to plan the location of a buffer zone, as it is not always possible to predict where the heating cable will end. The buffer zone is an area where heating is not essential, typically behind a toilet or adjacent to a door opening. This area allows for placement of excess heating cable. Heating cables may also be installed 6" (150 mm) from the wall to create a buffer zone.
  • Heating cable testing is required while the heating cable is on the spool and at two subsequent steps during installation to ensure cable quality and for warranty purposes. A megohmmeter is required for the insulation resistance testing of the heating cables. Insulation resistance testing is strongly recommended.
  • Consult a qualified electrician before ordering DITRA-HEAT heating cables to ensure you order the correct voltage for your installation.

Schluter®-DITRA-HEAT-E-HK are twisted pair heating cables designed for integration with the DITRA-HEAT uncoupling membrane in interior floor warming applications.

All substrates must be clean, even, and load bearing. Bond inhibiting surfaces must be removed prior to the application of DITRA-HEAT. For complete installation guidelines and warranty criteria, please refer to the downloadable Schluter®-DITRA-HEAT Installation Handbook or to the installation video online.

Note: Type, thickness, and format of the tile or stone surface covering must be suitable for the intended application. Minimum tile format is 2" x 2" (5 cm x 5 cm).

Alternate Floor Coverings over DITRA-HEAT Please refer to detail DH-AFC (see the Alternate Floor Coverings over DITRA-HEAT Technical Bulletin available for download below,) and the Schluter®-DITRA-HEAT Installation Handbook for complete installation guidelines.
