•
•
•
The customized installation plan (or layout)
A Warmup® Thermostat
Digital ohm meter (multi-meter)
30mA RCD
Electrical Junction box
Electrical conduit
Insulation material
Warmup® Foil mats must be fitted directly on top of the Insulation, and directly under the wood
laminate flooring.
Before installation always check the subfloor has adequate thermal insulation. This is particularly
important where the foil heaters will be used as a primary heat source. A heat loss calculation MUST
be carried out to ensure that the product will provide enough heat for your room.
See page 7 for information on suitable insulation materials.
How to select the correct heater or heater combination
Calculate the area of the floor to be heated. This is the total floor area minus any permanent
fixtures.
Length x width = m²
Select the heating mat or combination of mats closest in size to the area you want to heat. See
page 6 for the full range of heater sizes. .
Remember
Heaters cannot overlap
Heaters must be connected in parallel
A single thermostat can control up to handle loads up to 16 Amps.

Heater Information
Compatible Wood Laminates
Please ensure that your laminate flooring is suitable for use with electric underfloor heating.
Most wood / laminate floors are compatible with the Foil mats but we do not recommend
using any wood flooring thicker than 18mm.
Wood flooring with metallic strips as part of their locking systems are NOT compatible as these
metallic strips may damage the Foil mats.
Any wood floor with a pad already attached must not be used with the Warmup® Foil mats.
For a wooden floors or similar the thermal resistance should not exceed 0.15m²K/W.
Compatible Insulation Materials
The Foil Heaters MUST NOT be installed in thinset cement or in direct contact with a cement or
concrete subfloor. The heater MUST be installed on top of a suitable soft Insulation material. This
is necessary to prevent the heater from being damaged when the weight of the floor furniture and
people are added.
The insulation material should be at least 6mm thick and suitable for use with electric
underfloor heating.
It is important that you take into account the insulation properties, the better R value the shorter the
heat up time.
If using the Warmup® Insulation board or similar a soft underlay must be used to ensure the heater is
not in contact with the cement facing of the board.
NOTE: Underlayment papers are not compatible with Warmup® Foil mats.
Cutting and turning the mat:
In some instances, you may need to cut
turn and flip the mat to suit the room. It is
essential that you do not cut, twist or kink
the heating wire.
To make a cut separate the foil sheets at
the long edge of the heater to expose the
heating cable loops. Lift the cable out of
the way when cutting. Once aluminium
foil has been cut and the mat has been
repositioned, use the aluminium foil strips
provided to cover the exposed cable and
link the pieces of the mat.

Making Electrical Provision for the Heater
Electrical Requirements
As with all electrical projects which are subject to Part P, all electrical work must be carried out by a
certified electrician. All work must conform to the current IEE wiring regulations - BS7671:2008.
The system must be protected by a
dedicated 30mA RCD at all times.
For systems not exceeding 13 amps a
fused spur or 30mA RCD/spur that has
contact separation in all poles that provides full disconnection under over-voltage category III conditions must be used.
For systems larger than 13 amps a suitable
protective device that meets the current
wiring regulations must be used.
Connecting the thermostat
The thermostat should be installed in the
room to be heated. In the case of bathrooms or wet areas a electrician should be
consulted regarding whether a suitable
zone is available.
The thermostat can handle a load up to
16 amps. For larger installations exceeding 16 amps multiple thermostats may be required or it
may be possible to use a Contactor.
Once all of the connections have been made, the electrician must complete the relevant forms and
display at the fuse board as per BS7671:2008 Section 753.
Testing the heating element
A resistance tests should be carried out on the heating mat before, during and after fitting the
final floor covering.
Using a Multi-meter set at 2K ohms test across
• Live to neutral = ohms value as listed on Page 6
If you do not get the expected results or at any time you believe there may be a problem, please
contact Warmup’s Technical Team for guidance.
Record the readings on the control card at the back of the manual.
NOTE: Ensure that the floor sensor is tested before the final floor finish has been laid. The floor
sensor values can be found in the thermostat instructions. When testing the floor sensor ensure
that the meter can read up to 20k ohms.

Step 1: Planning Your Installation
Before installing, draw an installation plan showing the placement of the mats, floor sensor, and
junction box or boxes.
The Foil heating mats should cover at least 80-90% of the floor area of your room to be used as a
primary heat source*.
Choose the combination of heating mats that best enables you to cover the recommended 80-90%
of your room. Plan to use the larger foil heating mats as much as possible and to use smaller mats
only as gap fillers.
Note: The mats are supplied with a 3 metre long electrical cold lead. If you need longer
connection leads, these may be extended consult a qualified electrician.
*Depending on insulation, air-flow & overall heat-loss within the room, additional heating may be
required.
It is important to keep an accurate record of where the mats are installed.
Step 2: Check and prepare the subfloor
The Foil heater MUST NOT be installed in thinset cement, or in
direct contact with a cement or concrete subfloor.
There must always be a soft insulation / underlay beneath the
aluminium heating mats.
Carefully inspect the subfloor and make sure it is clean, free of
sharp edges, protruding nails and any other materials that may
damage the heating mat.
Lay the Insulation as per the manufacturer instructions.
If you are using the Warmup® insulation board you will need to
install a soft underlay on top of the boards.
Remove the foil heating mat from the packaging and check the
mats visually for any damage.
Test using a multi-meter and verify the correct resistance against
the table on page 6. Record the readings on the control card at the
back of the manual.
9
Step 3: Laying Out Your Heating Mats
Roll out the foil heating mats on top of the insulation material.
Keep the heating mat at least 50mm from the edges of the
room.
Ensure that the heating mat is completely flat. Care should
be taken not to fold or crease the mats at any time during
installation.
50mm
Position it in such a way that the power cord will be able to
reach the point where the thermostat will be connected.
If fitting more than one foil heating mat ensure that the mat
does must not overlap, as overheating will result. Leave a gap
of at least 20mm between each mat.
Secure the foil mat to the underlay using tabs of duct tape to
hold the mat in position.
Duct
Tape
Foil
Strips
If any of the wire has been detached from the foil mat (when
the mat is cut and turned) the wire MUST be covered by the
aluminium strips. The aluminium strips should also be used to
bridge the gap between the sections of the mat.
NOTE: This is essential in order to keep the earth circuit intact.
Secure the mats to the floor with tabs of duct tape. Since
the joint and the cold tail leads are slightly thicker than the
rest of the mat, you will need to create a slight groove in the
insulation to ensure the heating mat lays flat. Do not allow
the power supply cable to cross or come into contact with the
heating mat.
Once the heater(s) have been laid mark each pair of coldtail
leads coming from the same mat with a numbered sticker This
will make it easier to identify each mat once the floor covering
is laid.
10
Step 4: Install the thermostat floor sensor
Position the sensor approximately 300mm into the heated area
in-between the heating wires runs on the mat.
Do not allow the sensor tip to come into contact with any of the
heating element wires.
Warmup recommend the use of conduit when installing the floor
sensor. The conduit will protect the sensor and will allow for
easier replacement should there be a problem after flooring has
been laid.
Run the sensor cable back to the thermostat. The sensor wire
MUST not cross over the foil heater wires.
Test the floor sensor using a multi-meter. The floor sensor ohms
reading values can be found in the thermostat instructions.
Step 5: Install the floor
Before fitting the final floor covering test the heating mats to
ensure that they have not been damaged during installation. See
page 8 for details.
You are now ready to lay the final floor finish. Take care not to
damage the heating mats. Do not drive nails or screws into the
floor or cut the floor panels on top of the heater.
If the floor is not being laid immediately, all heating mats must
be protected with cardboard to prevent damage. Immediately
prior to the floor being laid, test the heating mat to ensure it has not
been damaged.
Step 6: Connect the thermostat
Once the flooring has been installed, connect the thermostat
ensuring that it is set to reach a maximum temperature of 27°C.
A Warmup® thermostat with a floor sensor MUST be used in
order to accurately monitor the floor temperature and your
comfort level.
Always zone each room with a foil heating system with its own
thermostat controller. This allows each room to be controlled
individually saving you energy by only heating the zone when
required.
