2. Choose a location
At this stage it its likely that an electric
underfloor heating system has been
installed and a back box is already in place.
The underfloor heating cold tail should
be pulled up through the back box, and
the sensor probe installed (in the conduit
provided) within the wall cavity or pre
chased channel in a solid wall.
