IMPORTANT!
Do not place items such as bean bag
furniture, thick rugs or floor-flush furniture
on your heated floor covering.

IMPORTANT
Read this manual before attempting to
install your foil heater.
Incorrect installation could damage the
heater and will invalidate your warranty.
Use of such items while the heater is
operating may result in a build-up of heat
which could damage your floor covering.

Getting Started
Before installing your new Warmup®underlaminate foil heating mats, be sure you have the following
additional parts:
Electrical junction box – used as the connecting junction for the electrical supply cables of the
heating mats.
Control thermostat – allows you to control the temperature of the room.
Residual Current Device - Consult your electrician regarding the applicable RCD.
Hard insulation materials – used as heat insulator under the foil heating mats in installations with
concrete subfloors to provide more efficient heating. The material comes in plates, usually made from
foamed Polyurethane or Polystyrene and should have Compressive strength of more than 28PSI
(2Kg/cm
Soft insulation material – any soft insulation suitable for wood or laminate. which has a fire rating
of B2 or greater.

). An example of this is the Warmup®Insulation Board.
Your Warmup® Underlaminate Foil Heater has been designed so that
installation is quick and straight forward, but with all electrical systems,
certain procedures must be strictly followed.

Important!
ALWAYS:
ALWAYS ensure all earth leads are connected to the earth ring.
ALWAYS ensure that the electric circuit that supplies electricity to the Warmup
Underlaminate heating system is equipped with a 30mA residual current
device (RCD).
ALWAYS connect all cold wire leads from the Warmup®Underlaminate foil heating
mats in parallel inside an electrical junction box or boxes.
ALWAYS ensure that the total current needed for all mats connected in parallel
is not more than 80% of the listed amperage capacity of the electrical
junction box and its power supply line and breaker (For advice consult
your recommended Part P qualified electrician).
ALWAYS provide each room with an Warmup®Underlaminate foil heating system with
its own electrical junction box and control thermostat. Each Warmup®thermostat
has a maximum capacity of 16 Amps. If the amount of Amps in the room is
greater than 16 Amps, divide the amperage over several thermostats.
(To calculate the amount of Amps in the room see tables in page 16).
ALWAYS use insulation under the mats to reduce running costs and warm-up
time. Check with your installer to determine the R value of the sub floor
insulation layer. If there is no insulation, or if the R value of the insulation
layer is lower than 0.57ft2*h*°F/Btu (0.1m2*°C/W or 1 Tog), please read
the insulation instructions on page 6 and act accordingly.
ALWAYS ensure that no sharp edges (e.g. metal-edged laminate locking systems)
come in contact with the foil heating.
®
ALWAYS fit the floor sensor and ensure that the thermostat is set for the correct
heater type and floor finish.
Note: Timber products often have a limitation on the maximum temperature allowed for floor heating- This

As with all electrical projects which are subject to Part P Building Regulations, all electrical work should be

To make a cut, turn the mat over so that
the loops are exposed. Lift the wire out of
the way when cutting. Once the aluminium
foil has been cut and the mat has been
repositioned, use the aluminium tape
provided to cover the exposed wire and link
the two pieces of the mat.

Step 1: Planning Your Installation
NOTE:
When laying two or
more heaters, ensure
the cold tails reach the
thermostat.
Before installing, draw an installation plan showing the placement of the
mats, floor sensor, and junction box
or boxes.
®
The Warmup
underlaminate foil heating mats should cover at least 80% of
the floor area of your room to be used as a primary heat source*. Warmup’s
foil heating mats are available in several convenient sizes. Choose the
combination of heating mats that best enables you to cover the
recommended 80% 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 3 metres of electrical cold leads.If
this is not enough, ask your electrician to extend the electrical
supply cables.
*Depending on insulation, air-flow & overall heat-loss within the room, additional heating may be required.
Step 2: Laying Out Your Heating Mats
1 Clean all debris from the floor base.
2 Insert Insulation as per the manufacturer’s instructions
3 Clean all debris from the surface of the insulating material.
4 Roll out heating mats on top of the insulating material. It is recommended to leave a gap of about
50mm from the wall to the heating mats, and a gap of about 10mm between each mat. Ensure that
each heating mat is completely flat. Make sure that the cold leads of the mats are on the side of the
mat that is closest to the location of the electrical junction box (See step 3 – Making the Electrical
Connection).

Since the joint is slightly thicker than

the rest of the mat, create a slight groove in the insulation
board under the joint to ensure that the heating
mat lays flat.
8 Mark each pair of cold leads coming from the same
mat with a number. Place a small sticker with the number
of each pair of leads close to the end of the lead.
Step 3: Making the Electrical Connections
Note: All electrical connections must be performed by a fully
qualified and Part P certified electrician.
Important! Tightly screw all connections to ensure good
electrical contacts.
Install the electrical junction box or boxes above floor level
1
according to local safety and building regulations and codes.
Place the following label (attached to back cover) on the
electrical junction box or boxes indicating that an underfloor
heating system is installed in the room.
2 Install the control thermostat as far as possible from any heat
sources or heat sinks such as fireplaces, direct sunlight, windows,
doors, or anything that could possibly affect proper temperature
readings. The suggested placement is 1.6m above floor level.

5 Connect the floor temperature safety sensor to the
thermostat through a conduit, and install between two
heating wire runs on the mat, at least 500mm from the
wall.

6 Create a groove in the subfloor to acccomodate the
floor sensor conduit.
Note: Make sure that the sensor is placed
between two runs of wire, at the opposite end
from the heating wire loop.
The probe wire must not touch or be crossed by
the heating element.
The end of the conduit must always remain
accesible if removal/insertion of the sensor is
required in the future
Page 11
Step 3: Making the Electrical Connections
7 Measure the resistance of the heating system and
record the value. Verify that the values you measure
are in line with the resistance value that is printed
on the specific mat nameplate.
NOTE: the floor sensor values can be found with
the thermostat instructions
8
All earth connections from the heaters must be connected to the earth from the power
supply of the house.
9 In parallel, feed each mat to the electrical junction box. Make sure that you can see
the sticker with the numbers of the leads. If necessary, shorten the leads, but make sure
the sticker with the leads' numbers are affixed to the shortened lead.
10Expose the conductor in each lead.
11 Connect all leads of the same colour.
12 Insert each coloured lead to one connector in the junction box.
13 Connect the same colour cold lead between the thermostat and the connector
in the junction box.
WARNING:
This product MUST be used with a dedicated
30MA RCD (residual current device).
The RCD should be tested regularly in accordance
with the manufacturer's guidelines.

the thermostat box.
15 Switch on the foil heating system (see the directions in your thermostat manual)for half
an hour to ensure that the system is working properly.It is important to check each entire
system to ensure each foil mat is heating.
16 Switch off the heating system (see the directions in your thermostat manual).
