Step 1 -
Electrical Supply
Install the RCD
Install a dedicated 30 mA RCD or use an existing RCD. No more than
7.5 kW of heating should be connected to each 30 milliamp RCD. For
larger loads, use multiple RCD’s.
NOTE: It is possible to run the heater(s) from an existing circuit
protected by a 30 mA RCD. It should be calculated whether or not the
circuit can handle the additional load.
NOTE: A junction box is required if more than two heaters are being
connected to a single Warmup thermostat.
NOTE: When conducting an insulation resistance test on the supply
to the thermostat the thermostat and heaters must be isolated or
disconnected.

Step 1 -
Electrical Supply
NOTE: In the case of bathroom installations, electrical regulations
prohibit the installation of mains voltage products such as
thermostats, contactors, fused spurs, isolators or junction boxes,
within Zones 0 or 1.
Any mains voltage product fitted within Zone 2 must have a degree of
protection at least of IPX4 or IPX5 if water jets are present.
It is common to install the thermostat outside of wet rooms in the
adjacent connected room in circumstances where it is not practicable
to install the thermostat within the wet room.
When installed in this way, using only the sensor probe to control the
heating, it is not possible to directly control the air temperature, only
the surface temperature.
All electrical connections must conform to the current BS 7671
National Wiring Regulations. Final connections to the main
electricity supply MUST be completed by a Part P qualified
electrician.

Substrate Considerations
Wall Preparation
Stud Walls
Stud walls with 600 mm centres, require 20 mm Warmup insulation
boards or thicker. 10 mm boards can be used for stud walls at
300 mm centres. Boards should be secured at 300 mm intervals on
each stud using screws and washers.
Solid Walls
Use a 6/8 mm trowel to comb adhesive over the whole surface of
the Warmup insulation board. For uneven walls increase to a 20 mm
trowel. Push firmly onto wall, staggering the joints.
NOTE: For full instructions please refer to the Warmup Insulation
Board manual.

Floor Preparation
Subfloors previously covered in vinyl, cork or carpeting: all old
flooring and adhesive must be removed. If there is bitumen as a
damp proofing layer, it must be covered with a minimum 50 mm of
sand/cement screed or overboarded with 10 mm Warmup Insulation
Boards, taking care not to puncture the bitumen coating. The screed
must be fully cured and dry before proceeding. If using other damp
proofing or tanking systems, contact the manufacturer for advice.
For optimum performance it is recommended that you use Warmup®
Insulation Boards beneath Warmup StickyMat 3D™. The insulation
will improve the systems response to heating demand, saving energy
and reducing running costs.

Step 3 -
Layout Planning
•For floor applications, ensure
that there is a minimum of
50 mm between any heating
cable removed from the mat
and that the cable is away
from the influence of other
heat sources, such as heating
and hot water pipes, lighting
fixtures or chimneys at all
times.
•The heating cable must not
be cut, shortened, extended
or le in a void, it must be fully
installed within the layer of
tile adhesive.
•When installing the StickMat
3D™ DO NOT cross the
cable over another run, over
coldtails or the sensor probe.
This will cause overheating
and will damage the cable.
NOTE: The heater should not be installed on irregular surfaces such
as on stairs.
Before you begin
•Heating cables cannot be
installed across expansion
joints within the floor. Where
a heated floor is divided by
expansion joints, individual
cables should be used to
heat each area. The cold tail
may cross the expansion joint
within a 300 mm long conduit
as shown.
NOTE: When installing the mat, maintain a spacing of 40 mm
between the heater and the perimeter of the room/wall or any
unheated areas.
A plan of the heater layout is required as part of the
control card so that any cutting or drilling aer tiling
will not result in injury or damage to the heater.

15
Step 3 -
Layout Planning
In order to fit your mat into a specific area, it may be necessary to cut
and turn the mat (examples below).
IMPORTANT: NEVER cut the heating element. When cutting and
turning the mat take care not to cut or damage the heating cable.
Please take a moment to double-check that your plan has the proper
room dimensions and that you have the correct size and proper
number of mats. Mats should run backwards and forwards between
walls and obstructions as shown in the examples.
NOTE: When laying two or more heaters, ensure all coldtails reach
the thermostat.

Step 4 - Install StickyMat 3d™
•Mark out the boards with a
permanent marker showing
where fixtures such as mirrors,
shower screens, towel rails
and other unheated areas are
going to be.
•Recommended Step - Install
Warmup Insulation Board
over either stud or solid walls
referring to their installation
instructions. Ensure that the
top surface of the boards are
smooth and clean.
NOTE: StickyMat 3D can also
be applied onto insulated
plasterboard or similar.
•Measure and record the
resistance of the heating
cable in the “Resistance
Before” column of the control
card, supplied as part of this
installation guide.
•Stop installation immediately
and contact Warmup if its
resistance falls outside the
range set out in the Reference
Resistance Band table.
•Secure the cold tail using
tabs of electrical tape. Cut a
section in the board for the
manufactured joint so that it
sits at the same height as the
heater. DO NOT tape over the
manufactured joint.
•In stud walls, the coldtail
can be threaded behind
the insulation board to the
thermostat location. For solid
walls, the channel a groove for
the coldtail in the insulation
board to the thermostat
location.
IMPORTANT: The coldtail
joint must be fully embedded
within the tile adhesive or
plaster being laid over.

Step 4 - Install StickyMat 3d™
•Install the sensor at least
300 mm into the heated area it
will be controlling, if installing
wall heating only.
•It should be located centrally
between parallel runs of
heating cable and not in an
area influenced by other heat
sources.
NOTE: If installing both
floor and wall heating which
is controlled using one
thermostat, the sensor should
be installed in the floor.
•At the end of the heating
cable, you will find a
termination joint. As with the
coldtail joint at the beginning
of the heating cable, this joint
will have to be cut into the
boards so that it sits at the
same height as the heater.
•DO NOT tape over the
termination joint, it must be
in direct contact and fully
embedded within the tile
adhesive/plaster being laid
over the heating cable.

•Begin laying the mat, cutting
the mesh and turning the mat
to fit the wall area. Secure the
mat to the boards using the
self adhesive mesh or double
sided tape. If required the mat
can be stabled to the boards
using a staple gun.
NOTE: DO NOT staple over
the heating cable.
•Follow the installation layout
as in Step 3 to complete the
heater placement.
•DO NOT install the heating
cable in temperatures less
than -10°C.
5
•Measure the resistance of
the sensor probe and record
it on the control card. If it’s
resistance is outside the
prescribed range contact
Warmup.
•DO NOT tape over the sensor
tip, it must be in full contact
with the heated tile adhesive
or plaster being laid over.

Tiled Walls
•Carefully lay the tiles and press
into the adhesive bed.
•Grout the wall as soon as
possible as per the adhesive
manufacturer’s instructions.
DO NOT switch on the heater
until the tile adhesive and
grout has fully cured. DO NOT
use the heater to accelerate
the drying process of the
adhesive.
•Cover the installation with a
full bed of flexible tile adhesive
using a notched trowel.
Take care not to damage or
dislodge the heating cable.
•Aer laying the first tile
remove and ensure the tile
is getting a full coverage
of adhesive from your
application.
•Ensure the width of the
grout line is in line with the
manufacturers instructions
for the size and type of tile
being used. Tiles must not be
removed once the adhesive
has set, doing so will damage
the heater.
NOTE: Please ensure that the tile adhesive used is compatible with
wall heating.
