Loose Wire Installation Systems

This method of heating is suitable to new builds and rennovations. The heating cable needs to be embedded into the screed surface during the early floor preparation. The heating wire can be spaced at various intervals to suit the heating requirements and is ideal for large and awkward shaped rooms and for heating conservatories.


Selecting the correct size heater for the installation:

    • Measure the square meters of the floor surface in the room, length x width = m2  x 100 watts per m2  for standard rooms.
    • Experience has shown that 100W/m2 of room area provides adequate heating for most domestic installations . To determine the heating required for the room multiply the total floor area in m2 by 100W.  In cold rooms and areas with double volume ceilings, multiply the total floor area by 120watts.  Round up to the nearest  heating cable.

  • Using the size guide, select the heating wire, or combination of heating wires closest to the size required  Eg a room measuring 2mx3m = 6m2.  The ideal heating wire to use is the UFBR600 (see below)  the which at 100mm spacing covers 3.36m2.  
  • Wire spacings should not be greater than 100mm as this may result in “streaky”heat – noticeable differences in temperature on the floor surface.

  • The installation complies with local, national wiring regulations as well as any other applicable statutory requirements.
  • The electrical circuit to which the cable is connected is electrically earthed and protected by a residual current device.
  • The cable is connected to an electrical supply of its rated voltage only

The 10 year warranty does not cover:

    • Faults arising from incorrect installations.
    • Faults arising due to incorrect specification and/or application of the heating system.
    • Faults arising from damage to the cable from outside causes, such as other suppliers, third party contractors, including (but not limited to)
    • cracking of floors or sub-floors through expansion and contraction or any  other reason
