Self-regulating Technology

What does self-regulating mean?

Many years ago Raychem developed self-regulating heating cables. They automatically adjust their power output to compensate for temperature changes.

Self-regulating Cable and How it Works

The outer jacket, braid and inner jacket provide mechanical, chemical and electrical protection... but the magic happens in the conductive core. The conductive core is extruded over the two, parallel conductors.

As the ambient temperature drops, the core contracts microscopically and the number of electrical paths through the core increases, producing more heat. Conversely as the ambient temperature rises, the core expands and has fewer electrical paths, producing less heat.

A self-regulating heating cable adjusts its power output along its entire length. That's what makes it a safe and reliable solution for many applications.

The advantages of a self-regulating underfloor heating system

  • Safety and reliability
    • Avoids overheating
    • The cable can be closely spaced
    • Maintenance-free
  • Easy installation
    • The cable can be cut-to-length (e.g. when it needs to be adjusted to complex room shapes).
    • The cable can be installed directly on the existing subfloor
  • Energy efficiency
    • By adjusting its output to the room temperature, energy consumption is optimised

A unique technology for more comfort and safety

Underfloor Heating in Winter

1. Near the door there is a cold draught

  • The cable senses the need for more heat, and increases its heat output.
Underfloor Heating in Summer

2. During the day, the sun heats the floor next to the window

  • The cable will lower its heat output automatically.
  • No risk of overheating.
Underfloor Heating under the Carpet

3. Under the carpet, there is less need for heat

  • The cable will sense this and lower it's heat output accordingly.
  • There is no risk of overheating or damage to the floor.

Raychem self-regulating electric underfloor heating certified for wooden floors

Leading manufacturers of wooden flooring have now certified Raychem's T2Reflecta self-regulating electric underfloor heating system as suitable for use under wooden floor coverings.

The Raychem system offers a reliable and durable solution, especially for parquet and laminate floors which expand and contract depending on the humidity and temperature. After the system is switched on the T2Red heating cable heats up slowly to ensure that the wooden floor is not damaged by abrupt temperature changes. Once the desired operating temperature is reached the system provides a uniform heat distribution across the entire floor.

Prior to the certification leading manufacturers of wooden flooring throughout Europe extensively tested the T2Reflecta system, and it has been proven that the system can be used under wooden floor coverings without concern.
