Description

A range of electrical underfloor heating system options, including thermostats and accessories.


Underfoor heating range:

  • T2Red: The innovative and unique self-regulating floor heating cable.

  • T2QuickNet: The ultra-thin heating mat (two power options available).
  • T2Blue: The robust, flexible, pre-terminated (dual wire, and screened) cable system.
  • T2Green: The low output heating cable designed especially for very well insulated and near zero energy houses.
  • RAYCHEM Custom Mats: The pre-fabricated underfloor heating mats are custom built to fit the exact dimensions of the floor area, with dual conductor braided heating wire laminated between two layers of polyester fabric.
  • CeraPro: The 3 mm ultra-thin, robust, under tile heating cable solution with 'tape and mesh' fixing accessories included. Suitable for tiles or natural stone covering.
  • 'Smart' thermostats which offer zoned, programmable heating control, a requirement of the Building Regulations Approved Document L.
  • A complete range of installation accessories and components including: Floor primers, adhesives and fixing accessories.


Consult technical literature for design (power output, cable length etc.) requirements depending on whether installation on new construction or renovation. Packs as well as individual components are available, consult manufacturer for details and insert requirements under 'Product reference'.


Self-regulating heating:

The cable automatically adjusts its power output long its entire length to compensate for temperature changes. This is achieved within the conductive core which is extruded over the two parallel conductors, as the temperature drops, the core contracts microscopically and the number of electrical paths through the core increases resulting in more heat being produced. Conversely the opposite occurs when the core expands and less heat is produced when the ambient temperature rises.


Features and benefits:

  • Avoids overheating. The cable can be closely spaced.
  • Maintenance free.
  • The cable can be cut to length and installed directly on to the existing floor.
  • Certified for use on wooden floors.
  • Energy efficient by adjusting the room temperature it can optimize energy consumption.
  • The manufacturer shall be able to provide heat loss calculations and corresponding selection of components.
  • Supply voltage: 230 V a.c./ 50 Hz.
  • Connections between the electrical supply, control panel and underfloor heating circuits shall be installed by an approved electrical contractor
  • Circuit breaker protection required by MCB (BS EN 60898 type C or D). Residual current device required, RCD (30 mA sensitivity, tripping within 100 ms).
  • Comfortable and safe.
  • Hassle free installation and maintenance free.
  • Energy-efficient and cost saving.
  • Can be installed under all floor coverings.
  • CE marked.
  • Total care warranty.
