Self-regulating: A unique technology for more comfort and safety
|
What does self-regulating mean?
Raychem self-regulating heating cables automatically adjust their power output to compensate for temperature changes. 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. More heat is produced.
Conversely, as the ambient temperature rises, the core expands and has fewer electrical paths. Less heat is produced.
See a demo of how self-regulating works |
| In colder areas, (e.g. near doors or windows), more heat is produced. |
In warm areas, (e.g. in the middle of the room or under carpets and furniture), less heat is produced. |

The advantages of a self-regulating underfloor heating system
|
During the day, the sun heats the floor next to the window.
- The cable will lower its heat output automatically.
- No risk of overheating.
|
|
Near the door there is a cold draught
- The cable senses the need for more heat. and increases its heat output.
|
|
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.
|
The advantages of a self-regulating underfloor heating system
|
1. Safe and reliable
- No overheating, the cable can be closely spaced.
- Maintenance-free.
|
|
2. Easy to install
- 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 sub floor.
|
|
3. Energy efficient
- By adjusting its output to the room temperature, the energy consumption is reduced to a minimum.
