## Long description

The DEVI DEVIflex 18T is a high-performance single-conductor heating cable engineered for professional underfloor heating systems. With a total power output of 310W and a length of 17.5 meters, this cable is designed to provide consistent and efficient thermal comfort in various indoor environments. Its robust construction ensures durability and reliability, making it an ideal choice for integration into concrete floor structures in both residential and commercial buildings.
Advantages
This heating cable offers exceptional durability and long-term operational stability due to its high-quality materials and advanced manufacturing standards. The single-conductor design facilitates precise installation, while the consistent heat output ensures uniform temperature distribution across the entire floor surface. By embedding the cable within a concrete screed, users benefit from an efficient thermal mass that retains heat effectively, providing a comfortable indoor climate even during colder periods.
Suitable for
Residential underfloor heating installations
Commercial building floor warming systems
Installation within concrete screed floors
Renovation projects requiring reliable floor heating
This product may not be suitable for installations in thin-set flooring systems where the cable cannot be properly embedded in a protective layer of concrete or screed. It is also not intended for outdoor use, such as snow melting on driveways or roof de-icing, as it is specifically designed for indoor climate control.
Key specifications
Power output: 310W
Cable length: 17.5 meters
Linear power density: 18W/m
System type: Single-conductor heating cable
Application: Indoor concrete floor heating
To install the DEVI DEVIflex 18T, the cable must be laid out according to the calculated spacing requirements on a stable, non-combustible subfloor. It should be secured firmly to the floor or reinforcement mesh before being covered with a suitable concrete screed. The system must be connected to a compatible thermostat to regulate the temperature and ensure safe operation. Always ensure the cable is not crossed or touching itself during installation to prevent overheating.
What to consider before purchase
Verify the total floor area to ensure the cable length is sufficient
Confirm the compatibility of your thermostat with single-conductor heating cables
Ensure the subfloor is prepared and level before installation
Consult with a qualified electrician for the electrical connection
Usage recommendations
Always allow the concrete screed to cure completely according to the manufacturer's instructions before activating the heating system for the first time to prevent cracking or damage to the floor finish.
