Warmtech underfloor heating Installation Instructions Manual - page 15
This is quite acceptable provided that:
a. The element is spaced at least 50mm
apart at all times. Not closer.
b. The element should never cross over.
c. Never allow the heating element to be
within the wall cavity, the black ‘power
supply leads’ only.
Once the laying of the element is complete
meaning the black leads are both back to the
starting point, these will need to be
carefully pulled up within the wall cavity
using the draw wire.
If the standard controller has been
upgraded to include a floor sensing probe,
the floor sensing probe must be installed
at this stage.
The floor probe (temperature sensor) is to
be laid as far into the centre of the floor as
possible (positioned exactly between 2
runs of heating elements – this is very
important for accuracy of temperature
control), still ensuring that the floor probe
lead (3 metres in length) can reach the
controller position up the wall.
