Step 1: Plan your installation & layout
Step 2: Lay insulation and install Conduit
It is important to plan out your installation to ensure minimal
wastage and achieve a more economical result. Draw a plan
of your room and mark out the position of Thermofoil Matting,
Marshalling Box, RCD, Thermostat, Thermostat back box and
Sensor Probe/Conduit.
Before installation always check the subfloor has adequate
thermal insulation. This is particularly important where
Thermofoil is the primary heat source.
When planning, take into account that Thermofoil needs to be
laid adjacent to each other and across the width of your room.
Also for stability it is also important to lay Thermofoil at a 90
degree angle to your insulation and floor finish.
Substrate Breakdown
Floor Finish
Vapour Barrier (5415)
If inadequate insulation is in place then Thermofoil should be
laid over Econoboard (6014) to ensure economical operation.
Before laying Econoboard check your substrate is level and
secure. If floor boards are absent, 50mm Econoboard (6150)
should be used.
Lay the Conduit onto the insulation, measure, and make a
groove for the Conduit to lay in. The recess should be deep
enough so it lays flush with the top on the insulation board.
Run the Conduit inside the wall cavity and into your Thermostat
(5259) back box. Feed Sensor Probe into Conduit as part of
Thermostat installation process. Consult relevant installation
guide for more information.

PRO TIP
The Sensor Probe is supplied with 2m of connection cable. The
ideal thermostat height is 1.3m from the floor. This will ensure
your sensor connection cable can be connected easily.
The Sensor Probe needs to be located in a representative area
of floor that cannot be covered by furniture.

Step 3: Lay Thermofoil and connect to an RCD
Step 4: Apply Vapour Barrier & floor finish
Ensure all electrical supply to has been switched off prior to
installation. Tape down Thermofoil and all connecting wires
to keep them secure. Run connecting wires to an accessible
Marshalling box or connection point mounted in the wall or in a
cupboard. ELEMENTS MUST BE INSTALLED IN PARALLEL.
The complete Thermofoil heating installation should be covered
with a 500g Vapour Barrier (5415) and the engineered or
laminate floor should be laid as specified by the manufacturer,
at a 90 degree angle to Thermofoil.

After care:
Once finished make sure all relevant contractors, in particular
bathroom and kitchen fitters know that electrical underfloor
heating is installed. This will reduce damage risk.
It is also important that adequate air circulation is maintained
at the surface of the floor. All items of furniture placed in the
heated area should be on legs or bun feet. This will ensure that
an air gap is maintained and the system does not over heat.
Use of mechanical floor fixings over the heating is prohibited.
