Coverage, resistance and testing
Calculating coverage:
Although 100% coverage with heating mats is achievable, a border of 20-40mm is recommended around the
perimeter of the room as the heating cables should not touch the walls. With kickboards we recommend going
as close as possible to the kickboard with the heating system to ensure that section of the floor where people
often stand is heated.
In normal circumstances we would recommend deducting between 5 and 15% from the total free floor space
that you wish to heat, to give you the square metres of heating mat that you should install (for instance using
2
mat in a room with free floor space of 8.5m2). Our recommendation is to deduct 10-15% for fitting
a 7.7m
space in rooms up to 15m
Multiple mats can be combined to provide a good coverage in a room, but the mats must always have the
same Wattage output per square meter.
Thermal resistance of coverings
The material used to cover the heating cable must have a density of at least 1,500kg /m3 and a minimum heat
transmission of 1W/m K. All normal tile adhesives, leveling compounds and screeds conform to this standard.
The thermal resistance (insulation) between the heating system and the room must not have an insulation
value higher than 0.125 m
heat from rising into the room). Some typical insulation values for common floor coverings are listed below:
Tiled, stone and thin vinyl floors up to
Linoleum floors and thick vinyl floors up to
Hessian backed carpets with low Tog underlays up to
Parquet and laminate floors up to 18mm thick up to
Wood fibre floors and rubber backed carpets from
Wood fibre and rubber backed carpets are not suitable for use with conventional underfloor heating systems.
Speak to Heat Mat’s Technical Support Team to discuss your options if you need to heat these surfaces.

Installation instructions
Please read pages
2 & 3 before
reading these
instructions
including the
Do’s and Don’ts
Floor prep
Before laying the heating mats the base must
•
be solid, level and dust free.
If the base is badly insulated and constructed
•
of a variety of materials you should use insulation
boards to ensure the system to heats up evenly.
We always recommend using a structural insulation
•
board on badly insulated bases to improve the
systems energy-efficiency. Soft insulation without
a concrete facing cannot be used.
Insulation boards should always be installed
•
following the manufacturers instructions and
reinforcement tape must be used to secure
the joins.
A wooden floor base should be suitably secured
•
to eliminate movement – 6mm and 10mm structural
insulation boards can be used for this purpose.
Before laying the mats the base should be
•
primed with a primer compatible with the levelling
compound or tile adhesive you intend to use.
Installing the Heating Mats
Before you start laying the heating mats
When installing the mats and walking on them
•
you should wear soft-soled shoes.
Each mat must be tested with a multi-meter
•
prior to installation commencing.
Before you start to roll out your mats take the
•
time to plan the layout of the heating mat/s.
As the mats are laid in parallel the cold-tails
of all mats must be able to reach the connection
point (usually the thermostat).
1 2
One or two heating mats can be wired directly
•
into the back of the thermostat, larger numbers
of mats will require a separate connection box.
If the system exceeds 16Amps a contactor will
be required to power the system.
How to manipulate the mats
The mat works on a cut-and-turn principle meaning
•
you can cut the mesh of the mat, which allows
you to flip the mat around and start laying it in an
alternative direction.
In awkward areas the heating cable can be removed
•
from the fibreglass mesh and laid loosely to ensure
the heating system fits your room. When doing this
try to keep the space between the cables similar to
that on your mat to maintain an even output across
the flo or.
Any loose cables should be secured to the floor
•
with double sided tape or a hot glue gun.
If the mats are slightly too long or too short you
•
can get them to fit correctly by cutting the mesh
between each run of cable. The runs of cable
can then be laid slightly further apart or closer
together to fit the area.
Cables should never be less than 40mm apart
•
whether they are on the heating mat or laid loosely.
If you find you have to lay the heating cables less
•
than 50mm apart, or more than 150mm apart for
more than 20% of the floor area the mats are not
the right size for the room.
The heating cable cannot be cut to shorten
•
it under any circumstances and cables
must never cross.

How to position the mats
The mats can be laid in any direction in a room, but
•
it makes sense to work out if one direction provides
better coverage than the other. For instance if a
room is 3.6 x 2.4m you could get 7 runs of mat
2.3m long running the mats length ways or
4 runs of mat 3.5m long if you ran the other way.
The first option provides a better
coverage of the floor.
If you only have one mat, start fitting
•
from one corner of the room (if the
cold-tail does not reach back to the
connection point you can strip some
heating cable from the mat to allow
it to reach).
Roll out the mat onto the floor mesh
•
side up (fig 2) until you reach the wall
or an obstruction and cut-and-turn
(fig 3 ) the mat to continue laying it.
Repeat this until you have covered
•
the floor (fig 4).
If you’re using multiple mats we recommend fitting
•
the largest mat first. We recommend rolling the
mat out to the furthest point of the room and then
working the mat back towards your starting point.
You must make sure you do not “paint yourself
into a corner” or leave isolated areas unheated.
If you have a small amount of mat left over when you
•
have covered the floor you can cut the mesh from
side to side between each run of heating cable,
and shuffle the mat together shortening the distance
between each cable run to use up the excess mat.
Alternatively, if you don’t have quite enough heating
mat you can cut the mesh and space the cable runs
slightly further apart to cover a larger area.
Only Hea t Mat cables inc lude:
A. Anti-crush cable jacket
B. 100% Ea rth shield
C. High-l oad earth drain wire
D. Kevlar anti-stretch protection
E. Litzer heating wires
F. 2 00ºC Fluoropolymer protection
Once all mats are in position, remove the backing
•
from the adhesive tape attached to the underside
of your mat/s and secure to your base (fig 5).
Any loose cable or mesh can be secured by
using a hot glue gun or masking tape. Walking over
the mats with soft-soled shoes will help the tape
stick to the floor.
The cold-tail connection and end
•
termination must be kept straight
and laid flat in a position that will
be beneath the final floor covering.
These may have to be chased into
the sub-floor / insulation board and
can be held down with double-sided
tape laid beneath them. These
sections must not be covered with
tape and must be fully encased by
tile adhesive or levelling compound
with at least 10mm of this on either
side of the connection. (fig 6).
A suitable floor sensor (usually
•
supplied with the thermostat)
should be installed to monitor the floor temperature.
A second ‘redundant’ floor sensor can be installed
if desired.
This must be placed a minimum of 300mm
•
into the heated floor area. This should be equally
spaced between the heating cables and must
not cross the heating cable at any point (fig 7).
The floor sensor can be encapsulated within
•
the tile adhesive or levelling compound used
to cover the heating mat, alternatively a
closed-end flexible conduit can be positioned
onto the floor base to house the sensor.

How much does electric underfloor heating cost to run?
Although some people believe underfloor heating (UFH) is expensive to run, the reality is that
both the initial installation fee and the ongoing running costs can represent great value for money.
It costs less than 14p to run 1m
Running costs of your Heat Mat system
will depend on:
• How well insulated the room is
• The output of your heating mats (110W are
lower output, 160W are standard and 200W
and 240W are the highest and only for use
under tile and stone)
• Your energy tariff
• How you program your thermostat
(see the next page for advice on this)
*These fi gures are based on H eat Mat’s 160W/ sqm heating mats la id directly onto 10mm H eat Mat Thermal in sulation boards w ith porcelain til es above in a proper ty meeting
the latest P art L Building Reg ulations standa rd. The energy cos t of 14.40p kWh is bas ed on PowerComp are’s UK average elec tricity price s for 2021. Prices are c orrect as of Nove mber 2021

Ensuring the thermostat is set up correctly
Your thermostat is supplied with fitting instructions and a ‘Quick Start Guide’
(NGTouch only). You can also download further information from our website:
www.heatmat.co.uk
Ensure the thermostat is set up correctly to
be as efficient as possible
1. Your heating schedule
The NGTouch allows you to program a series of
‘events’ per day to reflect your lifestyle. You can
set different times and temperatures for different
activities throughout the day e.g. wake up/getting
ready for work first thing in the morning to overnight.
Instructions on how to do this are included with
your thermostat.
2. Set the correct target temperature
If your system is running on air temperature then a
target temperature of 20ºC /68ºF would normally
result in a warm room. If your system is running
on floor temperature then a target temperature of
30ºC/86ºF is normally required for a warm floor.
3. Monitor air or floor
If your thermostat is in the same room as the
heating system we recommend setting it to room
sensor with floor limitation. If it is outside of the
room it should always be set to floor sensor
(floor limitation should always be used for electric
underfloor heating installations).
The NGTouch has a number of features
to make managing your UFH easy.
Comfort mode – You set the temperature
and the time. This is a temporary override to the
heating schedule you have programmed, allowing
you to adjust the temperature to suit the conditions
at the time e.g. turn it up for a couple of hours.
Boost mode – A short burst of heat. Boost
allows you to switch the heating onto maximum
power for an hour to rapidly heat the room and
create a cosy environment.
Holiday mode – Walk into a warm home after
your holiday. This mode allows you to program
the start and end dates of your holiday, maintaining
an even floor temperature of around 5ºC for frost
protection while you’re away. The heating is
activated in time for your return so you walk
back onto warm floors.
Frost protection – Stop the floor from
freezing. Frost protection turns the heating off
but prevents the floor from freezing by maintaining
a steady, very low temperature of 5ºC. This could
be used in a holiday home for example.
Calling us for support programming it
Our technical support team is available from
8:30-am to 5:30pm Monday – Friday to assist
with any queries.
Call 01444 247020 or request a call back
via our website www.heatmat.co.uk
Eco mode – Allows you to save energy in
between heating ‘events’. This function lets
you quickly turn off the heating until the next
‘event’. Despite running on your normal daily
schedule, Eco mode, pauses the heating system
to save energy. It can be found under the
Advanced settings menu.

What to avoid
Thermal blocks
• Avoid thermal blocks on the floor as they can
cause the floor to get very warm beneath them,
wasting energy- beware of thermal blocking, we
do not recommend the use of large flat based
pieces of furniture, rubber backed carpets, 70’s
bean bags, wet washing left on floors and large
dog beds on heated floors as these items trap
the heat by preventing air movement. All furniture
placed on heated floors must have at least a
30mm air gap beneath its base.
• Never thermally block where the floor sensor is
as it will lead to your thermostat switching off the
heating system too early.
• Manufacturers of wooden, laminate and LVT
floors have maximum floor temperatures they
advise for their products. Ensure your controller’s
maximum floor temperature limit is set to these
recommendations.
• Never drill down into a floor that contains a
heating system if you can avoid it. If you must
drill into a heated floor (for instance to install a
door stop) contact Heat Mat for details of their
thermal imaging sheets, which can show the
location of heating cables (although they can’t
be used to locate the floor sensor).
Thermostats
• Avoid obstructing the wall-mounted thermostat
as this has an internal air temperature sensor and
blocking air movement around the thermostats
may cause an incorrect temperature to be read.
• Ensure the thermostat is not exposed to
direct sunlight.
• Do not use water to clean the wall-mounted
thermostat! Use a soft cloth with a suitable
plastic cleaner.
• The system will have a floor temperature sensor
installed beneath the wall mounted thermostat
Avoid placing objects that may cause a heat
build-up above this sensor as this will switch
your heating system off prematurely.
Homeowner Guide Pull out and keep
• Always ensure that your heating system
is correctly programmed to eliminate
energy wastage, contact our technical
team on 01444 247020 for assistance.
Floor construction and walls
• Avoid disturbing the floor construction,
if door stops or similar items are to be
installed consider use a Heat Mat cable
trace sheet which will be able to show
where cables are installed and enable
drilling to be carried out without damaging
the heating system.
• Do not expose the floor finish to standing
water for long periods of time, although
mopping your tile or stone floor is fine.
• Do not drill into the wall around or directly
beneath the wall mounted thermostat as
there will be 230V power cables present.
• If the floor is flooded then the floor must
be fully dried out before the system is used,
it must not be used to dry out the floor.
The system should also be electrically
tested before use again.
Other things to consider
• If a system or thermostat appears to
not be working correctly or is damaged
during installation we offer full support.
Call our technical team on 01444 247020
for assistance.
• If a system has been damaged during or
subsequent to installation Heat Mat can
arrange for an independent engineer
to visit, establish why the system is not
working, and repair the cable in situ.

The sensor cable can be extended if required
•
up to 100m using a twin sheathed high-temperature
resistant PVC cable.
The floor sensor should not be fitted in areas
•
affected by other heat sources such as hot water
pipes and radiators or in an area that will be
covered at a later date with items such as rugs
or flat-bottomed furniture, as this will prevent
the system from operating correctly.
Test the heating system again with a multi-meter
•
prior to covering.
Take a photograph of the layout of your system and
•
the position of the floor sensor for future reference.
If the floor covering is not being fitted immediately
•
protect the heater/s by covering with cardboard or
carpet and restrict any traffic above the cable to a
minimum. After removing the protective covering
before laying the final floor covering you should
test the cables again before proceeding.
Laying the final floor covering
Take care not to crush or damage any heating
•
cables during installation of the floor covering,
even a small nick in the outer insulation of the
heating cable can lead to system failure over
a long period of time.
If the cable is damaged a repair kit should
•
be used to fix the damage.
We recommend that flooring installers regularly
•
check the resistance and continuity of the cable
with a multi-meter during installation. Alternatively
Heat Mat’s Cable Safe Monitor can be used to
provide a warning of any damage to the elements.
For installing beneath standard tiles or stone
•
we recommend skimming the mats with a
3mm layer of flexible cementitious tile-adhesive
or using a latex screed to cover the cables.
Once this layer has hardened you can begin tiling.
Tiles must always be fully bedded in and must
•
not be laid with dabs of adhesive.
Care must be taken when tiling and cleaning
•
out grout lines not to cut or catch the heating cable.
If installing mosaic tiles, carpets, vinyl and bonded
•
wood coverings a layer of 12mm of cementitious
flexible levelling compound must be used to
cover the cables ( Heat Mat can supply this).
When laying tile adhesive or levelling compound
•
a plastic notched trowel should be used to push the
adhesive along the cables rather than against them.
The underfloor heating must never be used to
•
‘dry-out’ the tile adhesive or levelling compound.
The system must never be turned on until all
adhesives and compounds are completely dry.

with floor temperature limitation. Please see the
separate instructions in your Heat Mat thermostat box.
Run the coldtail connection and floor sensor cable in
separate plastic conduit or trunking from your heated
floor to the thermostat position.
Up to 2 heating mats can be wired straight into the
thermostat. A connection box will be required if installing
3 or more heating mats. Ensure that multiple mats are
wired in parallel, not in series.
The mains power supply must be protected by a
suitable RCD ( 30mA and up to 4.8kW ).
The thermostat should be connected to the power
supply via a suitably rated fused spur or circuit breaker.
Heat Mat’s thermostats are rated 16 Amp and if the total
loading from a combination of heating mats exceeds this,
we would recommend the installation of a suitable rated
contactor which would allow the heating system to be
run through a single thermostat for ease of control.
Please check the IP rating of your chosen thermostat
to ensure it meets with the current wiring regulations
for its chosen installation position.
If the thermostat is placed outside the room to be heated,
or inside a cupboard, the thermostat will have to be
reprogrammed (when first switched on) to only monitor
the floor sensor that has been placed into the heated
floor space.
Some of Heat Mat’s thermostats are IP21 rated,
and the heating mats are IPX7 rated, which means
systems can be installed in bathrooms and other
‘wet areas’ and if a suitable zone is available the
thermostat can also be placed in the bathroom.
