The advantages of a self-regulating underfloor heating system

Safe & Reliable

No overheating, the cable can be closely spaced.


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.

Energy Efficient

By adjusting its output to the room temperature, the energy consumption is reduced to a minimum

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.

Underfloor Heating

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.

Wooden Floors

Raychem self-regulating technology has proven unique advantages for wooden floors

Raychem self-regulating heating cables automatically adjust their power output to compensate for temperature changes. That makes them ideal for temperature-sensitive floors such as wood. Several leading European wooden floor manufactures have intensively tested Raychem T2Red and T2Reflecta and have certified that they are safe for use under temperature sensitive wooden floors.

Wooden floors "live". They swell or shrink, depending on the atmospheric humidity and temperature. High floor temperatures or fast temperature changes can damage the floor.

The T2Red cable senses the thermal conductivity of the top floors and automatically adjusts its heat output.

The "gentle" heat-up of the system also prevents damage to the wooden floor.

Carpets or furniture can be safely placed on the wooden floor without the risk of overheating.


Top firm; very knowledgeable, good value for money, honest. highly valued contractor

Tim Clark

Glenfair have changed my business round since they started doing work for me. The video surveilance system they fitted is of such great quality I am able to check on the manufacturing side wherever I am in the country.

William Dyer

Very reliable and friendly service. Would recommend.
