Danfoss heating cable mat
type 100/150
Danfoss heating cable mats are primarily
used when renovating existing floors where
a low floor construction height is required.
Danfoss heating cable mat is only 4 mm
thick, plus the thickness of the floor surface.
Danfoss heating cable mats 100 provides an
output of 100 W/m2per mat. If your requirements exceed the m2output of 100 W/m
2
e.g. in the case of badly insulated stone
floors or old concrete floors in basements,
you may wish to use Danfoss heating cable
mats 150 which have an output of 150 W/m2.
The required output should be determined
by an authorised electrician.
Areas of use!
Danfoss heating cable mats 100 W/m2can
be installed in wooden floors, plaster or concrete floors. Danfoss heating cable mats 150
W/m2must only be installed on a concrete
surface or similar.
NB!
Must be installed in accordance with local
building regulations.
Must be connected by an authorised
electrician.

General Installation Guidelines
The following guidelines must be observed
when installing Danfoss heating cable mats.
Preparation
1. All traces of old floor covering must be
removed so that the concrete surface or
the floorboards are visible.
2. Clean the surface and remove any loose
particles.
3. The floor must be securely anchored to
prevent it from shifting. Floor plaster is
recommended for wooden floors to
prevent the formation of cracks in joints
and clinkers. The floor must be smooth in
order to prevent any damage to the heating mat.
4. The floor must be primed.
5. Any gaps in the floor around outflow
pipes, floor drains and doorsills, or near
the outer edges where the floor screed
may penetrate, must be filled.
6. You are advised to draw up an
installation plan before laying out the
mats.
Use page 9 in this manual to draw up a
plan.
Remember to indicate the sensor tube,
connection tails and the connection to
the cold cable.
NB!
Please consult the manufacturer for information on suitable temperatures if using
Danfoss heating cable mats 100 under
wooden floors the concrete layer must not
be less than 5 mm on top of the cable.
Please note when using 2 mats!
The sensor must be positioned between the
two mats as illustrated – this is important as
it must be able to detect the temperature of
both mats.

Installing the Danfoss heating cable mats
The heating mat should not be installed at
room temperatures below 5°C.
The heating mat must be installed in accordance with the installation instructions.
Roll out the mat on the primed floor with the
adhesive side on the bottom and the heating
cable on the top.
Distribute the heating mat evenly across the
floor surface, avoiding areas where the mat
may be squeezed or damaged by screws,
e.g. from the toilet. The heating mat should
lie flush against the surface and be securely
fastened to avoid any movement of the mat
when the floor screed is laid.
If the heating cable mat is rolled out towards
the opposite wall, the mat will need to be
cut before being rolled back.
To do so, cut the mat material carefully without damaging the heating wire. Next, flip the
mat over and roll it back parallel to the first
length of mat, etc.
DO NOT CUT THE CABLE ONLY THE
MESH.
NB!
The heating mat must not be shortened or
exposed to mechanical stress.
The heating mat must not be fitted below
objects that can produce heat, e.g. tumble
driers.
Please observe care when installing the mat
and laying the screed in order to prevent
damage to the heating mat.
When turning the heating mat just cut the
mesh. Do not cut the cable.
Test the heating mat in accordance with the
table on page 8 (resistance) before the
screed is poured.
4
The flex tubing for the thermostat’s sensor
should be positioned so that the sensor is
located between the heating conductors on
a clear patch of floor. A thermostat should
always control the heated area.
NB!
Do not fit under cupboards, bathtubs, or
similar.
NB!
Please see text and illustration page 2 if
installing two mats on the same surface.
The flex tubing may be countersunk into the
floor to reduce the floor construction height.
Seal the flex tubing at the end so that the
screed cannot penetrate the tube.
The sensor cable and the cold cable for the
heating mat should be connected to the
thermostat box or directly to the thermostat
located elsewhere in a convenient position,
e.g. near your electric meter.
Test the ohm value of the heating mat before
applying the screed.
When covering the mat with screed, please
follow the manufacturer’s recommendations
as regards the drying time of the screed.
Humidity seals and floor coverings such as
vinyl and wooden floors require all moisture
in the screed, depending on the thickness,
to have been eliminated fully in accordance
with the drying times recommended by the
manufacturer.
The under floor heating must not be used
until the screed has dried out fully, usually
around 28 days.
5
The mat should be tested as specified
earlier before the floor covering is laid.
The installation should be equipped with a
circuit breaker.
The heating cable mat is designed for under
floor heating purposes only.
The heating mat must be embedded.
Controlling the heating mat
Danfoss thermostat type 520
Danfoss heating cable mats 100/150 may be
controlled by means of Danfoss thermostat
type 520 which is flush mounted. The thermostat keeps the floor at a constant temperature by means of the floor sensor, which
should be placed between two loops or mat
sections.
Danfoss thermostat type 550
Danfoss heating cable mats 100/150 may be
controlled by means of Danfoss thermostat
type 550, an intelligent thermostat with digital display and built-in timer for lowering the
temperature at night.
Please contact your supplier for further
information.
IMPORTANT
Please consult the manufacturer for information on suitable temperatures if using
Danfoss heating cable mats 100/150 under
wooden floors, laminate floors or vinyl.
