DOMESTIC HEATING - MISCELLANEOUS HEATING
under-tile heating
Technical Specification
Construction
• Twin Core 160W/m2 cable.
• Fully screened for use in bathrooms or other wet areas.
• Two layers of insulation for maximum cable life.
• Easy to cut mesh backing that can be removed for small and awkward areas.
Electrical
• All installations should be carried out by a qualified electrician in accordance with the current wiring regulations.
• All installations require an RCD (residual current device) for safe operation.
• The Dimplex thermostatic controller has maximum load of 15A.
• Connecting more than two mats to a controller requires the use of a standard electrical junction box.
• The Dimplex thermostatic controller comes complete with a floor sensing probe.
Installation Guidelines
The Dimplex under-tile heater can be fitted to:
• Timber suspended floors.
• Concrete solid floors.
• Dimplex strongly recommends the use of 10mm insulating tile backer board to maximise system performance.
Design Freedom
By being concealed under the tiled floor, under-tile heating frees you to plan rooms and arrange furniture as you want, allowing a great deal of flexibility.
Flexible Control
Because Dimplex under-tile heating is controlled independently of the main heating system, it offers maximum flexibility. Separate settings can be programmed whether you are in, out or even on holiday, and the early start function always ensures the floor has reached your chosen temperature when you want it.
Safety and Practicality
A warm tiled floor helps spills to dry quickly, avoiding slip-ups in bathrooms and kitchens, promoting a safer environment for all the family.
