For more detailed information on any of their products it is highly recommended to go to their Web Site to see all of what they offer and they have plenty of instructions and information.

Schluter Systems
Cable Installation

It is recommended that the installation of the DITRA-HEAT system is photographed (e.g., heating cable layout, floor temperature sensor placements, transition splice location, end splice location, and wide view of the room) for reference with future renovation work and troubleshooting. The homeowner/end user should retain these photos for their records.

Schluter Systems Schluter Systems Schluter Systems
Schluter Systems Before the heating cable is removed from the spool, conduct the first set of required tests and record values in a heating cable tests log. If a break or damage is detected during the tests, return the heating cable to the original place of purchase. Schluter Systems Thread the heating cable cold lead and remote sensors through a conduit from the base of the wall to the thermostat electrical box. The heating cable cold lead must not be cut. Schluter Systems Mark where the cold/hot splice will be placed, cut the DITRA-HEAT matting, and insert the splice. It may be necessary to temporarily secure the splice to the floor with thin-set mortar or adhesive (e.g., KERDI-FIX or hot glue).

Once the heating cable cold lead and remote sensors are threaded to the thermostat electrical box, install a metal protection plate at the base of the wall. This will help prevent any damage from fasteners (e.g., nails, screws, etc.) in the future.

Schluter Systems Schluter Systems Schluter Systems
Schluter Systems Embed the heating cables between studs, at a spacing of 3 studs (3-1/2"). Closer spacing may result in overheating and damage to building structures. A wider spacing may not provide sufficient power to warm the floor. Schluter Systems Use care not to damage the cables during installation, particularly before the cables are embedded in the matting.  
Notes:
  • Make sure to leave space for inserting the floor temperature sensor(s).
  • Heating cables may not touch, cross over, or overlap one another.
  • The maximum allowable length of a single run is 10 ft (3 m); the cable must be turned or a u-shaped "jog" created at this point (see image above).
  • Minimum spacing from:
    • Walls or fixtures (e.g., cabinets) is 3"
    • Other heat sources (baseboard heaters, fireplaces, forced air heating ducts, etc.) is 8"
    • Plumbing drains is 6"
Schluter Systems Schluter Systems Schluter Systems
Schluter Systems Install the thermostat sensors between two cable runs, at a distance of at least 24" from the wall. Mark the sensor location on the DITRA-HEAT and cut the matting to house the sensor. It is recommended to temporarily remove the heating cable from the area while cutting the matting. It may be necessary to temporarily secure the sensor to the floor with thin-set mortar or adhesive (e.g., KERDI-FIX or hot glue). Embed the sensor wire in the matting without overlapping or crossing the heating cable. Schluter Systems Once the heating cable and floor temperature sensor installation is complete, retest and record values in a heating cable tests log.
Waterproofing

The following steps are required for waterproofing only:

Note: While the heating cable is protected by the DITRA-HEAT matting, be careful when applying the mortar to not damage the cable with the notched trowel.

Schluter Systems Schluter Systems Schluter Systems
Schluter Systems At the joints, fill the matting with unmodified thin-set mortar, approximately 8" wide, centered over the joint. Schluter Systems Comb additional unmodified thin-set mortar over the joint using a 1/4" x 3/16" V-notched trowel or the KERDI-TROWEL, which features a 1/8" x 1/8" (square-notched design. Schluter Systems Apply 5"-wide KERDI-BAND, centered over the joint. Using the flat side of the trowel, firmly press the banding into the mortar to ensure 100% coverage and to remove excess mortar and air pockets.
Schluter Systems    
Schluter Systems At all wall junctions, apply KERDI-BAND as described in steps 1-3, centered where the wall and floor meet. In some applications the vertical section of the floor/wall transition will not accept a bond to unmodified thin-set mortar. Connections to such elements can be achieved using KERDI-FIX sealant and bonding compound or suitable trowel-applied waterproofing materials, such as those that require atmospheric moisture to cure (e.g., urethane sealant).
   Note: KERDI-BAND must lap DITRA-HEAT at seams and at floor/wall transitions by a minimum of 2" in order to maintain waterproof integrity.
Tiles

Note: While the heating cable is protected by the DITRA-HEAT matting, be careful when applying the mortar to not damage the cable with the notched trowel.

Schluter Systems Schluter Systems Schluter Systems
Schluter Systems Tile can be installed over DITRA-HEAT immediately; no need to wait for the mortar to cure. Fill the matting with unmodified thin-set mortar and comb additional mortar over the matting using a trowel that is appropriate for the size of the tile. Schluter Systems Solidly embed the tiles in the setting material, making sure to observe the open time of the bonding mortar. If the mortar skins over prior to tile installation, remove and reapply. Schluter Systems Periodically remove and check a tile to ensure that full coverage is being attained.
Note: Coverage may vary with mortar consistency, angle at which the trowel is held, substrate flatness, etc. If full coverage is not achieved, remove and reapply, making sure to verify proper mortar consistency and application. For large-format tiles, e.g., 12" x 12" and larger, back-buttering the tiles with a skim coat of thin-set mortar is a useful way to help ensure proper coverage. The skim coat can fill in the concave area on the back of the tile (ceramic tiles are not perfectly flat) and improve contact with the mortar combed on the substrate.

ESTIMATED THIN-SET COVERAGE

To bond DITRA-HEAT to the substrate:
Use one 50 lb. bag of mortar per 100 sq.ft.

To bond the tile to the DITRA-HEAT, using a 1/4" x 3/8" square- or U-notched trowel:
Use one 50 lb bag of mortar per 40 - 50 sq.ft.

To bond the tile to the DITRA-HEAT, using a 1/2" x 1/2" square- or U-notched trowel:
Use one 50 lb bag of mortar per 30 - 40 sq.ft.

Schluter Systems Once the tile installation is complete, retest the heating cable and record values in a heating cable tests log.  
Operating Tips

  • Do not place furniture or mats over the floor temperature sensor. They can act as insulation and raise the floor temperature reading at the thermostat. This may cause the heating to turn off before the remainder of the floor reaches the desired temperature.
  • Area rugs are not recommended over the DITRA-HEAT system.
  • Futons, mattresses, floor-level furniture, pillows, etc. must not be placed directly onto the heated floor. Placement of items directly onto the heated floor will prevent heat diffusion (i.e., air circulation) and could result in damage.

DITRA-HEAT COMPONENTS

DITRA-HEAT Membrane

The DITRA-HEAT membrane is designed to secure the system heating cables and serves as a universal substrate for tile coverings. Similar to DITRA, the original uncoupling membrane, DITRA-HEAT provides uncoupling to neutralize the differential movement stresses between the substrate and the tile covering to prevent cracked grout and tile, waterproofing to protect moisture-sensitive substrates, vapor management, and support.

Heating Cable

The twisted pair heating cable is available in 120 and 240 Volt formats. The cables can be installed without returning to the thermostat and produce virtually no electromagnetic fields.

Digital Thermostat

The digital thermostat controls the floor temperature and is offered in both a programmable and non-programmable format. The thermostats feature a built-in Ground Fault Circuit Interrupter (GFCI), digital display with backlit screen, and support both the 120 and 240 Volt cables. The programmable thermostat also includes 250 preset programs.

Various KERDI waterproofing accessories are available. Use KERDI-BAND to seal butt joints or corner joints. KERDI-KERECK pre-formed seamless inside and outside corners and KERDI-SEAL-PS for sealing around pipes or KERDI-SEAL-MV seals mixing valve protrusions, and KERDI-DRAIN Assemblies. KERDI-TROWEL also available for installation of thin-set mortar.
