Description

Electrical heating cable for the DITRA-HEAT-E system

The electrical heating cable Schlüter-DITRA-HEAT-E-HK is installed in the uncoupling mat Schlüter-DITRA-HEAT and is used for applications in floor and wall assemblies. It is available in lengths from 4 to 244 meters. Since our systems are certified for waterproofing, the heating cables are approved for use in bathrooms and wetrooms.

In floor areas, the heating cables can be installed immediately after adhering DITRA-HEAT, using a minimum spacing of 9 cm (every third stud ≙ 136 W/m²).

For wall installation, the heating cables are installed once an adequate adhesive bond has been reached. The installation spacing is either 6 cm (around every second stud ≙ 200 W/m²) or 9 cm (every third stud ≙ 136 W/m²). The use of mats is recommended for wall assemblies.

Use the cable tester Schlüter-DITRA-HEAT-E-CT to measure the resistance of the electrical heating cables DITRA-HEAT-E-HK and the remote sensors supplied with DITRA-HEAT-E thermostats. The testing device should be used to monitor the resistance of the heating cables during the entire installation phase and alerts the installer with an acoustic signal in the event of damage. The cable tester automatically shuts down 60 minutes after the last key activation (values will not be saved).

Heating cable installation

    1. For installation in floor areas, heating cables may be installed immediately after adhering the uncoupling mat DITRA-HEAT, using a float or roller.
      For wall installation, the heating cables are installed once an adequate adhesive bond has been reached.
      Heating cables must never overlap or touch each other.
    2. Create a corresponding indentation in the area of the sealed cable end.
      Note: Use the cable tester Schlüter-DITRA-HEAT-E-CT to continuously measure the resistance of the electrical heating cables DITRA-HEAT-E-HK. The device monitors the resistance of the heating cables during the entire installation phase and alerts the installer with an acoustic signal in the event of damage.
  1. Floor areas:
    The stud spacing in the uncoupling mat is 3 cm. The installation spacing in the floor area must be
  • at least 9 cm (around every third stud – the equivalent of 136 W/m²)
    Closer installation spacing - especially in floor areas - may lead to overheating and can cause damage to building structures.
    Avoid stepping directly onto heating cables during the installation work.
  1. Wall areas:
    Depending on the available space, the desired surface temperature and the required heat output, the installation spacing in wall areas can either be
  • 6 cm (around every second stud – the equivalent of 200 W/m²) or
  • 9 cm (around every third stud – the equivalent of 136 W/m²)
  1. The transition from the heating cable to the connection cable (sleeve) is indicated with a label. The 'cold leg' (4 m) must be connected directly to a junction box or thermostat. The 'cold leg' may be shortened to a max. length of 1 m before the fitting. The heating cables may not be shortened.

Thermostat:

The heating cables of the DITRA-HEAT system may only be operated with DITRA-HEAT-E thermostats.
