The Schluter DITRA HEAT E HK Cable is an electrical under tile heating cable with a unilateral connection for installation in the Schluter DITRA HEAT Matting and DITRA HEAT DUO uncoupling matting. The Schluter DITRA HEAT E HK Cable is available in 17 different lengths for single zones. Note: these cables must not be shortened. When selecting the heating cable for your application, please note that the table below with the heated space in m² does not specify the room size. To determine the heated space, deduct unheated zones such as perimeter areas and storage space from the room size.
The Schluter DITRA HEAT E HK Cable can be installed in the matting on both walls and floors. It is recommended to set the spacing of the cable at 3 studs apart in the matting for floors, this gives a heat output of 136 W/m². For walls, the cables can be set at 2 studs apart – this gives a heat output of 200 W/m². The Schluter DITRA HEAT E HK Cable is easily installed in the matting by using an old grout float to press the cable down in between the studs. Please see the table below to see how much cable you need.

What wattage does the system run at on timber and concrete?
The system is designed at 136 w/m².
How many cables can be attached to a thermostat?
Each Schluter Ditra thermostat can have 2 cables per stat to a maximum loading of 3600w (16 amps) or 2300w (10 amps)
Do I have to put thermal insulation boards down first?
You definitely don't have to, but for more efficient heating we recommend a rigid insulation layer below the kit to create a thermal barrier.
How far away from the wall should I place the cable?
It is recommended that the cable is positioned at least 2 studs (60 mm) away from walls or any building element e.g. wall, column, bath, toilet etc.
How far apart should the cables be placed?
