Electrical underfloor heating systems.
A range of electrical underfloor heating system options, including thermostats and accessories.
Features and benefits:
Underfoor heating range:
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.

Standard product features | Design: The manufacturer shall be able to provide heat loss calculations and corresponding selection of underfloor heating cables, system layout and schematic drawings, electrical schedules indicating cable length and circuit protection, controller configuration listing and wiring diagrams. Electrical connection:
Installation: The underfloor heating cables shall be installed in accordance with the design plans, within the defined maximum circuit length, tested and commissioned strictly to manufacturer instructions and closely coordinated with the responsible sub-contractors. |
Product Options | Self-regulating, underfloor heating cables: - T2Red:
- T2Red with T2Reflecta:
Constant wattage custom underfloor heating mats: - RAYCHEM Custom Mat: Custom designed; consult manufacturer for details. - Constant wattage standard underfloor heating mats: Complete with two wire constant wattage cables (to ensure negligible electro-magnetic field generation), Teflon inner and LSZH outer jacket, electrical braid (to provide electrical protection) and a flat cold lead cable (to enable a lower profile installation). Pre-terminated heating cable, fixed within the mat and held in place by the matting itself and not by fixing tape (to avoid air gaps and associated potential hot spots). The overall thickness shall be no more than 3 mm (including the mat base). The heating cable shall be easily detachable from the mat (to lay loose cable around obstacles). The underfloor heating mat shall be self-adhesive and PVC free. - T2QuickNet:
