Professional underfloor heating !
Things to consider...
Heat Outputs
Floor Coverings
The maximum output from an underfloor heating system is
often stated at 70 W/m2 for timber floors and 100 W/m2 for
screed floors.
Most floor coverings can be laid on UFH systems.
In buildings that meet current Building Regulations, it is
unusual to require more than 70W/m2 heat output, based on
a 20OC internal design temperature.
In older buildings it is important to consider greater heat
losses. Conservatories, rooms with high ceilings and areas
that are poorly insulated may require supplementary heating.
As with any home, the more effective insulation you have,
the more efficient heating system you will gain.
When designing conventional heating systems it is necessary
to know the required heat output to determine the size of
the heat emitter. When designing an underfloor heating
system, the heat emitter is the floor area and is fixed.
The heat output achieved is a direct relationship between
the difference in floor surface temperature and room air
temperature. The floor construction, floor covering material,
pipe size, pipe spacing (or pipe centres), and the temperature
of water circulating through the UFH pipes are major factors
that determine the floor surface temperature.
For optimum performance, masonry coverings; ceramic
floor tiles, slate, stone, marble, etc. are chosen as this offers
minimum thermal resistance.
Wooden floors and carpets may also be used. Uponor
recommend a maximum combined thermal resistance of
0.15m2K/W is not exceeded for floor coverings. Carpet
underlays should be less than 1.0 TOG and should be suitable
for use with underfloor heating, while carpets should have a
maximum 1.5 TOG value.
Thick felts, thick underlay (TOG value greater than 1), and
cork should be avoided.
More detailed information regarding floor coverings can be
found in the User Instructions chapter, page 36.
Insulation
In older buildings it is important to consider greater heat
losses. Conservatories, rooms with high ceilings and areas
that are poorly insulated may require supplementary heating.
As with any home, the more effective insulation you have,
the more efficient heating system you will gain.
NOTE: Consult your flooring supplier for additional
considerations such as maximum temperature
limits, wood drying conditions, special glues, etc.
NOTE: Refer to building regulations for further
information about insulation.

Planning Your Installation
�������
��������������
Before laying any pipe, time should be spent planning a route
from the manifold location to the respective zones.
Once you have a clear idea of the installation, you can begin
to lay the pipe.
Manifold Location
���
During the pack selection process, a central and accesible
location is specified for the manifold, and this position must
not change during installation.
In the example shown to the right, the manifold is located in
the storage cupboard under the stairs. As the designer has
defined four zones, the manifold has four ports. In properties
with larger rooms, 2 or more loops may be required for a
heated zone.

���
Loop Allocation
Also during the pack selection process a “Pack Selection Table”
will have been filled in, either on the computer or on paper. This
form is now required as a guide to your installation. The Pack
Selection Table identifies how many loops of pipe are required
for each heated zone. Below is an example drawing showing the
loop and zone allocation from the Pack Selection Table.

utility
kitchen/dining
Plan to install one zone at a time, in a methodical order,
as pipework must not cross over. Utilise the ports of your
manifold sequencially, from the first to last or vice versa.
Allow room for your pipe to ‘run’ to zones and ‘return’ to
the manifold.
W/C
st.
TIP: Lay pipe 100mm from walls, so not to damage
pipes when installing your
floor convering.
TIP: Lay feeds to heated zones at 50mm centres
between flow and return pipes. Leave space for
feeds routed through other areas.

Solid Floor Installation
INFO: Floor must be level, and swept clean of dust and debris before starting your installation.
Insulation
NOTE: Edge Strip
Fix the edge insulation
continuously around all internal
and external wall edges, using
the adhesive backing. When
installed correctly the PE-skirt
will face out from the wall and
the embossed ‘Uponor’ will be
legible.
Insulation must conform to Building Regulations.
Lay the floor insulation over the entire floor area, butting up to
the edge strip, ensuring the PE skirt overlaps. Tape the PE skirt
onto the floor insulation. The Klips will grip to the insulation
to secure pipe in position. A protective membrane may be
required to protect the insulation from chemicals in the screed.
Please consult your screed supplier for guidance. If a protective
membrane is required, lay this immediately over the insulation.
You will lay pipe on top of the membrane and the Klips will
pierce through.
TIP: If you do not require a protective membrane,
you can prevent screed from slipping between
sections of insulations by taping at the seams.
Planning Your Installation
When installing underfloor heating on a solid floor, it is
imperative the pipes do not cross over each other.
Before laying any pipe, time should be spent planning a route
from the manifold location to the respective zones. Once you
have a clear idea of the installation, you can begin to lay the
pipe.
utility
kitchen/dining
W/C
Each loop must be installed without any joints in the floor.
To assist with installation, Uponor pipe is marked every metre.
Keep reference of how much pipe has been laid whilst installing
over the intended floor area. This will help ensure you return to
the manifold with sufficient pipe.
st.
st.
If required, lay more than one loop to a zone.
hall
Laying Loops
IMPORTANT! A loop is one continuous run of pipe from
the flow port to a return port
of a manifold. Never join two coils in
attempt to create one longer loop of pipe.
Start with the first or last coil to be run from the manifold.
In the case of the example, the installer could begin with either
the living room or the kitchen/dining, We will start with the
living room. Take your first coil and temporarily secure the end
of the pipe at the manifold by lodging it behind.
living room
hall
Pipe should be laid 100mm from external and internal walls
until you reach the zone you have planned to install first.

Once you reach the entry
point for this zone, pipe
direction is to the coldest
area of the room first, for
example, along external
walls and under windows.

Travel to the furthest point of the room and make a 180O turn
as shown in the drawing below.
The pipe needs to ‘meander’ back and fourth across the floor
at 200mm centres on it’s return to the entry point, then follow
the same route back to the manifold.

Once the first loop is complete work through the others one
after another. The example started with a loop for the living
room zone. The next zone in the example will be for the hall &
WC, followed by the utility and finaly the kitchen.
Insulating Congested Pipe
In order to prevent the floor from overheating directly below
the manifold or through doorways, or any areas where pipes
may be closer together, we would advise insulating the pipe,
especially if they are not used to heat the room through which
they pass.

First Fix Plumbing & Wiring with
Water Temperature Control
Every underfloor heating installation will require a hot water feed from the boiler to the manifold. The
Heating Pack is designed to have the primary pipe work from your boiler enter the manifold assembly on
the bottom left. Various components in the one pack will need connecting to your existing electrics.
Adding to an existing system.
First Fix Wiring
An ‘S plan’ plumbing arrangement is required to run an
underfloor heating system along side your existing heating
and hot water circuits. An S plan arrangement will allow UFH,
radiator and hot water circuits to be controlled independently,
each by two port motorised* zone valves. If a mid position (Y
plan) arrangement is present on an existing system that you
wish to add to, Uponor advise altering the arrangement to S
plan, removing the mid position valve and inserting a two port
motorised zone valve to isolate the radiator circuit and a second
two port motorised zone to isolate the hot water cylinder. The
Uponor One Pack provides a third zone valve for the underfloor
heating system.
A 230V fused spur will be allocated to the UFH system at
or near the manifold location, to supply all of the electrical
components within.
CAUTION: All wiring must be completed by a
competant person and must comply with
current IEE regulations.
Digital Wired Thermostats
A 2 core plus earth cable with a minimum cable size of 0.5mm
and a maximum cable size of 1mm is required for use with the
digital wired thermostats.
NOTE: Two port zone valve supplied by others if required.
Position the thermostats in each zone, out of direct sunlight
and away from other heat sources or draughts.
First Fix Plumbing
Each digital wired thermostat needs be wired back to the zone
controller, which should be positioned above the manifold.
The zone valve should be fitted on the pipe work between the
boiler (on the positive side of the primary pump) before the
manifold.
Optional floor sensor, for digital wired thermostat, is supplied
c/w 4m length of 2-core cable.

Filling & Pressure testing
Filling
Prior to filling the system check each connection on the
manifold and Compact Control Pack is tight. There is an integral
fill/vent valve above and below the pump. Two hose unions are
required to connect onto the 3/4” thread.
• Ensure all electrical supplies are switched off.
• Remove the fill port caps and connect a hose union to each.
• Fit a hose to the lower manifold hose union and run the
other end of the hose to a suitable drain point.
• Connect a hose to the upper manifold hose union and
connect the other end of the hose to a mains water tap.
• Individual loops need to be purged of air in turn. This is
• The integral valves in both end caps must be opened to fill
the system. Use the square key in the cap to open the fill
port valves.
• Ensure the thermostatic control valve and lockshield valve
are CLOSED and all connections are tight. To close the
control valve on the V5 Compact Control Pack, first remove
the white thermostatic head and use cap to close the valve.
achieved by opening the manual head (blue cap) on the
lower manifold, then fully opening the corresponding
topmeter on the upper manifold. To fully open the
topmeter, remove the red locking ring and turn the
topmeter 3 full turns from the closed position. Before
attempting, read ‘TM manifold loop balancing procedure’
later in this chapter..
• Slowly turn on the water tap. As the first loop fills with
water, air will discharge through the hose to the drain. Once
the air stops and there is a steady flow of water, close both
ports on the manifold. Repeat this procedure for all UFH
loops on the manifold ensuring that the valves are closed
on each loop after filling.
• Remove the white cap from the lockshield valve and close
off with an Allen key.
• Fully close the valve on the elbow of the Compact Control
Pack at the circulating pump inlet to ensure that water is
forced around the UFH loops when filling and not short
circuiting between the upper and lower manifold headers.
• Close the valves on the end caps and switch-off the mains
water before disconnecting the hoses.
• Important: Please remember to open the valve at the
circulating pump inlet.
IMPORTANT! Remember to open the valve at the
circulating pump inlet.
IMPORTANT! Fill loops independantly of each other.
•
Close all underfloor heating loop flow and return valves on
the manifold.
26
NEW One Pack Installation Guide.indd 26
5/2/2013 2:27:39 PM
Pressure testing
A hydraulic pressure test must be carried out on all loops
prior to laying the screed or covering with the chosen floor
coverings. A hydraulic pressure test kit is available from Uponor
(Item Number 1004057).
• Isolate the primary flow and return to the manifold.
• Ensure that all flow and return valves to the UFH loops are
open.
• Use the pressure gauge on the pressure test kit to monitor
pressures.
• Connect a pressure pump to the hose union and open the
valve on this end cap. Ensure the other hose union valve is
closed.
• Uponor recommends that the system should remain under
pressure whilst the floor is laid so that if any damage occurs
to the pipe, the laying of the floor can be stopped and
the damage repaired immediately. The floor should be laid
immediately after the pressure test.
• Where there is a danger of freezing, suitable measures
such as the use of glycol-based antifreeze should be
taken, using the correct mixture of water and antifreeze
solution. However, before start up, the glycol mixture must
be thoroughly flushed out of the system and disposed of
carefully.
• Pump up the pressure in the manifold to 2 x the operating
pressure (minimum 4 bar, maximum 6 bar) for at least 1
hour. After an initial slight drop in pressure as the pipes
expand, there should be no further drop in pressure. Check
the pressure gauge during this period to ensure that the
pressure remains constant under this period.
Use of Corrosion Inhibitors
Uponor UFH pipes will not be:
• Adversely affected by corrosion inhibitors normally used in
central heating systems.
• Adversely affected by accidental contact with linseed oil
based sealing compounds, or soldering flux. However, the
latter should not be used for making joints to the pipe.
• Affected by soft, hard or aggressive potable water. The
pipe will not be attacked by any constituents of concrete,
screeds, mortars, and is fully resistant to attack from micro
organisms.
Settings
• The thermostatic head is set to the required water flow
temperature for the underfloor heating system, typical
settings as follows:
Screed floors: 40 – 45OC
Wooden floors: 50 – 55OC
• The high limit thermostat does not need any adjustment. It
is preset to 60OC.
• The lockshield valve needs to be opened so that it forces
the majority of the water around the UFH system. The
primary and secondary pump speeds, existing primary
pressure and manifold size will affect how far open the
lockshield valve needs to be opened, usually around 3
full turns from the closed position. The lockshied valve
may need to be opened less/more depending on system
performance.
• To make an adjustment first unscrew and remove the white
cap. Use the included Allen Key to adjust the valve.
• To calibrate it is recommended that the lockshield valve
is first fully closed and then opened until you see the
thermometer continuously reading the same temperature as
the setting on the injection valve head.

When the system has been connected to the heat source and all
pumps, controls, valves and bypasses fitted, the system
• If removed, refit all thermal actuators.
• With the electric power off, initially set all room thermostats
should be checked and started as follows.
• Where applicable, ensure that the screed has had sufficient
time to cure in accordance with manufacturers instructions
and relevant British Standards, typically between 21 – 28
days.
• Check and ensure all electrical controls are wired correctly
and in accordance with the latest edition of IEE Wiring
Regulations, or ETCI National Rules for Republic of Ireland.
• The system set-up and control arrangement should be
checked to ensure correct operation.
• Check that the system is filled with water and fully vented
of air and all isolating valves are fully open. Once this is
complete, the pumps should be run for 5 minutes on the
“Venting Function” setting and then a final check
should be made to ensure that all air has been
vented from the system.
• Check that the boiler is operating in accordance with the
manufacturers instructions and set to run with a flow
temperature at least 15oC higher than the UFH design flow
temperature. (CCPV5 only)
• Ensure all flow meters are fully open and that auto balance
has been activated.
5oC above current room temperature so that they call for
heat.
• Set the water temperature control at the lowest possible
setting (between 25 - 30oC).
• Switch on the UFH system and ensure UFH pumps are
running and all relevant valves are open. Remember that the
thermal actuators take some time to operate and there will
be a 2 – 4 minute wait before they are fully open.
• If the foregoing procedures have been completed
satisfactory, turn all room thermostats down and wait for the
system to stop.
• When the system has stopped, turn up one room thermostat
at a time and wait for the system to start. Then confirm that
the correct circuit (loop) actuator(s) has opened for that
particular room and immediately turn the room thermostat
down again in that room.
• Wait until the system has stopped and then repeat the
process on a room by room basis, ensuring that every
actuator is controlled by the correct thermostat and that
each one switched the system on and off. This should also
include the boiler being switched on and off, providing there
are no other user circuits, e.g. radiators and/or hot water
primary circuits, calling for heat.
• Run the system at the lowest possible setting for at least 3
days, before raising the water temperature to the maximum
design temperature, which should be maintained for at least
a further 4 days.
• Set the room thermostats to the required levels and
programme the system controls to run as required.
• When running normally, the temperature difference between
the manifold flow and return connections may be between
5-10oC.

Fault Finding
Initial checks of for the primary system
If the water arriving at the manifold is either cold or below the
design temperature, check:
• the boiler is firing
• the primary pump is fitted
• the primary pump is working
• the boiler is of adequate size
• the primary pipework is sufficiently sized
Fault finding - Electrical Problems
In all cases where an electrical fault is reported it is always
prudent to check the obvious before replacing components.
• Is there an electrical supply?
• Is it switched on?
• Are there any fuses that may have blown and need
replacing?
• Are any components overloaded?
• Is everything wired correctly?
Under no circumstances replace a fuse with a higher rating than
stated for that piece of equipment.
The following flow chart is designed to aid the installer in
electrical fault finding for the radio/wired zones.
If a loop or loops fail to warm, when other zones are working
correctly.
General things to look for:
• Check that the corresponding manifold valves are open
• Check that there is a demand from the corresponding room
thermostat and/or the thermal actuator is open on demand.
• There may be an air lock in the loop, which will require
purging. Either shut down all other loops by closing
the valves at the manifold or turn down all other room
thermostats. This will concentrate all pump pressure to the
problem loop and may shift the air blockage. If all else fails
the loop can be flushed through with high-pressure water
following the instructions detailed in Filling, Venting and
Pressure Testing.
If circulation is apparent but poor, it may be that the lockshield
valve on the manifold requires adjustment.
If the system is too noisy. General things to look for:
• There is no air in the system
• That all pipes are firmly clipped in place and that the
manifold brackets are tight.
• That excessive pressure from another circulator in the
system is not interfering (hence the importance of having a
primary bypass).
If the running costs are high. General things to look for:
• That the UFH system is correctly electrically connected to
the boiler to prevent short cycling and to ensure that the
boiler is not running when it is not required.
• That the room temperatures and thermostat settings are not
too high (typical comfort temperatures are 20OC in living
quarters and 18OC in bedrooms).
• For any open windows or draughts. It is not unknown for
windows to be opened in cold weather, as the internal
comfort remains constant with thermostatic controls.
• That the boiler is running correctly. Has it been serviced
and/or commissioned by an approved engineer.
• That the floor downward losses are high due to inadequate
level of floor insulation.
The system is losing pressure. General things to look for:
• If the system is losing pressure either during testing and/
or after the system has been filled, but the flooring has not
been laid, simple visual/manual checks around the manifold
and along each loop of pipe should identify the problem
area.
• If there are no clear visual signs, each loop/circuit may
require a separate pressure test to identify the exact
location.
• If the floor has been laid, identification of the fault can be
traced through signs of a wet patch around the leak.
Obviously to make the repair, the floor will have to be raised. In
screed floors, excavate carefully in the centre of
the wet patch.
• Any leaks on the manifold are generally due to the
connection and any loose nuts and unions will require
tightening.
Check the pump isolating valve on the V5 Compact Control Pack
is open.
If a room fails to warm. General things to look for:
• That the room thermostat fitted is calling for heat and
that the valve has opened using the visual window on the
actuator.
• That the room thermostat is connected to and
communicating to the correct actuator(s).
• That the room thermostats are not operating in temperature
set-back mode.
• That the primary flow and return connections are installed
correctly and not crossed over at the UFH manifold.
• That the primary water temperature is not too low. This
needs to be at least 15OC higher than the UFH system water
temperature when using CCPV5.
• That the lockshield valve on the V5 Compact Control Pack is
set correctly
• Thermal resistance of floor covering is not too high, as this
could reduce the floor heat output.

Repairs:
To make a repair to the pipe, follow the processes below:
For 16mm PEX pipe Items required:
• 2 x compression adaptors, item no 1057441
• 1 x 1 x compression coupler, item no. 1006641
• Plastic pipe cutter
• Denso tape
Repairing the pipe:
• Isolate the damaged pipe loop at the manifold.
• Cut out the damaged section of pipe.
• Slide the adaptor nut and olive over each end of the pipe,
prior to inserting the insert/sleeve into each end.
• Offer both ends of pipe/inserts to the compression coupler
and tighten both nuts.
• Ideally, the joint will require an inspection chamber in case
further maintenance is required. However, in practice this
is often not practical, and the fitting is wrapped in suitable
tape before burying in the screed (ensure approval with the
building inspector is sought prior to doing this).
• Pressure test
• Location of any repair joint should be recorded for future
reference.

Frequently Asked Questions
Q. Who is one-pack for?
A. One-pack is for anyone who wishes to install and underfloor heating system for a floor area of up to 75m². Any competent DIY enthusiast or
tradesman can install it by following the simple installation guide or watching the on-line videos.
Q. Where can I get it from?
A. One-pack can be ordered from any plumbing or builders merchant throughout the UK and Ireland. Simply give them the code from the on-line
calculator so that they can place the order.
Q. How long does the delivery take?
A. Typically 3 working days.
Q. What are the benefits of one pack?
A. No need to wait for a quotation and a design. Simply use the on-line calculator to produce the quote there and then. When it comes to the
installation just watch the videos or follow the guide to install your system.
Q. What is a zone?
A. It’s an area that you wish to control independently via a room thermostat. It can be one room or multiple rooms but most commonly one.
Q. What is “water temperature control” WTC?
A. This is used when the supply water temperature from the heat source is too high for the underfloor heating. Typically a screeded floor system requires
an average water temperature of 40°c.
Q. What type of room controls should I use, radio or wired?
A. Each has an advantage over the other. Radio gives you the freedom to re-position your thermostats and it also cuts down on material and labour
costs. Wired has a permanent power source and does not use batteries.
Q. I have an existing radiator system, can I still use a one-pack?
A. Yes you can, it’s very likely that you would require either a diverting valve or a two port zone valve to isolate the two different systems. It’s also likely
that the underfloor heating will require water temperature control so as to reduce the higher water temperature that is typically required for a radiator
system.
Q. Can I expand the one-pack system in the future i.e. add another zone?
A. Yes you can, all our manifolds can be coupled together so it’s easy to increase the number of ports for additional loops. Please note that it is not
recommended to exceed a maximum number of twelve ports and you must always make sure that the pump size is suitable for the required out puts
and pressure drops.
Q. Can I use a one-pack for my conservatory?
A. Yes you can although you must consider the heat losses of the room. It maybe that an additional heat source is required should you wish to use a
conservatory all year round.
Q. What is a manifold?
A. A manifold is a central distribution point where the underfloor heating loops are connected to. It’s also used for control and isolation of the flow of
water so that loops/zones can be independently controlled.
Q. Where should I position my manifold?
A. Ideally in the most central point that gives the most economic distribution of pipework. However if it’s just a single zone then it is best to position it
within that area or as close as possible.
Q. Does the one-pack contain everything that I need?
A. The only thing the one-pack does not contain is either diverter valves or two-port motorised zone vales. It may not be necessary to install these
depending on the heating system and the type of pack that you have chosen. If you are unsure whether your system needs them, then please consult
with a professional plumber or heating engineer.
Q. Can I use a one-pack for a timber suspended floor?
A. One-packs are only designed for solid screed floors.
Q. What type and thickness of screed should I use?
A. Typicaly 65mm to 75mm thick using a ratio 4:1 sand and cement. For liquid flow screeds please consult with the manufacturer.
Q. What thickness of floor insulation should I lay?
A. This should be sufficient to satisfy building regulations Part L. Typically 100mm of high density floor grade PUR board is deemed sufficient. Please
check with building control prior to installing.
Q. What is the warranty period for a one-pack?
A. Pipework is guaranteed for 25 years, electrical and mechanical items are guaranteed for 1 year.
Q. What happens if I damage the pipe?
A. Uponor can supply compression couplers that can be used to join the pipe together. Any joints within the floor should be suitably protected from the
screed and if possible they should be made accessible.
Q. What type of finished floor coverings can I use?
A. It’s possible to use any type of floor covering provided the thermal resistance does not exceed the British Standard BSEN1264. For a wooden floor or
similar the thermal resistance should not exceed 0.15m²k/w. For carpets and underlay the combined tog value should not exceed a value of 2. Tiled
floor finishes are well suited for use with underfloor heating as they have little if any thermal resistance.
Q. Can I lay underfloor heating underneath kitchen units and sanitary items?
A. You can lay underfloor heating underneath kitchen units provided there are no floor fixings being used that could potentially damage the pipe. It’s
recommended that you lay underfloor heating across the total floor area as the kitchen layout could change in the future. Underfloor heating is not
normally placed under sanitary units as they are commonly fixed to the floor and could potential cause damage to pipes.

Maintenance
The system is virtually maintenance free with the UFH pipes
having a design life expectancy in excess of 50 years. However,
propriety equipment such as pumps, valves and other electrical
or mechanical components are all subject to wear and failure
after prolonged use. Uponor strongly recommend you take out
an annual maintenance agreement with a competent Heating
Engineer/Plumber to cover your entire heating system.

Floor Coverings
Careful consideration should be given to the choice of floor
finishes and coverings for floor heated rooms.
It is important to choose floor coverings that are suitable for use
with UFH and ideally, to maximize the system energy efficiency,
select materials with relatively low thermal resistances; heat
needs to pass from the water in the embedded pipes upwards
to the floor surface and then emit into the room itself, however
if high resistance floor coverings are used a greater amount of
heat will be contained in the floor structure and lost to ground
or the room below.
UFH systems are designed to warm the upper surface of the
floor to between 25 to 29oC when in operation.
Always check suitability of floor coverings with the flooring
supplier before purchasing, with particular attention given to
maximum temperature limits of flooring material and adhesives,
together with any special installation requirements.
The floor covering thermal resistance should not exceed
1.5 m2K/W; as per harmonized British and European Standard
BS EN 1264.
Vinyl & Amtico, typically have a low thermal resistance, but
tend to be limited to around 27oC maximum floor surface
temperature. The vinyl tiles/sheets should be glued down with
a higher temperature adhesive that is suitable for use with UFH.
Use manufacturers’ 2 part HT adhesive with Amtico floors. The
heating should be switched off for 48 hours prior to installation
and left off for another 48 hours after installation of the Vinyl
floor.
Carpets (> 0.5 m2K/W thermal resistance):
An underlay and carpet combined value of up to 2.5 TOG is
acceptable when fitted onto a heated screed floor, although the
underlay used should not exceed 1.0 TOG and must be suitable
for use with UFH. Most underlay is of moulded waffle sponge
rubber construction and is suitable, but avoid felts, heavy
rubber crumbs and polyurethane underlay.
Recommended underlay includes:
• Duralay Heatflow by Interfloor (Tog = 0.75)
• Tredaire Technics 5 by Interfloor (Tog = 0.56)
• Tredaire Technics 6 by Interfloor (Tog = 0.66)
Low resistance floor coverings (<= 0.5 m2K/W thermal
resistance):
Ceramic tiles, marble, slate, limestone, flagstones are all
excellent materials for covering heated screed floors, especially
in areas where heat losses may be excessive. Use a quality two
part flexible adhesive, rated to at least 50oC, to continuously
bond tiles/slabs to the floor substructure and flexible edge
joints to avoid cracking.
Polished Screed, which is highly conductive and well suited for
use with UFH.
• Roma by Ball & Young (Tog = 0.8)
For timber suspended floors the additional resistance imposed
by the floor boards need to be taken into account, therefore low
TOG value carpets should be used.
Solid wood boards up to 25mm thick, engineered hardwood
flooring up to 20mm thick and laminate boards are all
compatible with UFH. For Solid wood it’s important to maintain
moisture content of about 10% when laying. When installing
floating floors onto screed a thin low thermal resistance
underlay is required, such as: 2.75mm thick Duralay Heatflow
for laminate & solid wood floors (Tog = 0.35).
