Fast, Clean Installation with the DITRA-HEAT System

The DITRA-HEAT-E-HK cable is designed to snap directly into the DITRA-HEAT membrane without requiring clips, staples, or additional fasteners. Because the cable does not require encapsulation with self-leveling compounds, installers can complete projects faster while reducing labor and installation complexity.

Its innovative layout also eliminates the need for a return run to the thermostat, simplifying cable routing and improving installation efficiency.

Installation advantages include:

• Snaps securely into the DITRA-HEAT membrane
• No clips or mechanical fasteners required
• No self-leveling compounds needed
• No return cable to the thermostat
• Faster and more streamlined installation

Designed for Safe and Reliable Performance

Proper installation is essential for maximizing heating efficiency and long-term performance. Schluter recommends maintaining minimum clearances from walls, plumbing fixtures, drains, and other heat sources while following the specified cable spacing requirements.

Each cable includes a floor temperature sensor to provide accurate thermostat control. Insulation resistance testing before and during installation is also strongly recommended to verify cable condition before the finished flooring is installed.

Important installation considerations:

• Never cut or shorten the heating cable
• Install only within the DITRA-HEAT membrane
• Follow recommended spacing guidelines
• Observe minimum installation clearances
• Includes floor temperature sensor
