Danfoss offers a comprehensive heating cable program - there is a Danfoss floor heating system suitable and optimized for every purpose imaginable. Heating cables are mostly used in connection with new-builds or with larger renovation projects, where a completely new floor construction is laid out.

We have always placed professional installers at the center of our design and innovation process. We constantly talk to both Danfoss and non-Danfoss users, finding out as much as we can about how our products function in practice and what improvements you would like to see. Danfoss ECflex is the result.

In designing the Danfoss ECflex cable, our engineers focused on improving both ease of use and durability. As a result, Danfoss ECflex is even stronger, more flexible and more reliable than the established EFTPC product it replaces. To improve ease of installation, we have given both the cable and the cold lead of Danfoss ECflex a round profile to prevent curling and make it easier to bend. It also features fully screened twin conductor cables and an easy-strip, reinforced single-cable cold lead. Danfoss ECflex is cost-effective, versatile, easy to install, exceptionally durable and fully compliant with the IEC 60800:2009 product standard. It can be used in various applications:

  • New-build or renovation

  • Concrete floors

  • Pipe-tracing

  • Danfoss Reflect system for wooden and laminate flooring

  • Single-use concrete hardening (special 30 W/m output version)
