NOTE: Refer to building regulations for further information about insulation.

NOTE: Consult your flooring supplier for additional considerations such as maximum temperature limits, wood drying conditions, special glues, etc.

Heat Outputs

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.

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.

Floor Coverings

Most floor coverings can be laid on UFH systems.

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.

Planning Your Installation

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.

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

TIP: Lay pipe 100mm from walls, so not to damage pipes when installing your floor convering.

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.

TIP: Lay feeds to heated zones at 50mm centres between flow and return pipes. Leave space for feeds routed through other areas.

Loop AllocationAlso 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.

IMPORTANT! Pipes must not cross over each other.

INFO: Floor must be level, and swept clean of dust and debris before starting your installation.

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.

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.

If required, lay more than one loop to a zone.

Laying Loops

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.

Pipe should be laid 100mm from external and internal walls until you reach the zone you have planned to install first.

Solid Floor Installation

Insulation

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.

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.

NOTE: Insulation must conform to Building Regulations.

TIP: If you do not require a protective membrane, you can prevent screed from slipping between sections of insulations by taping at the seams.

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.

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.

Lay the pipe as you walk, securing every half a metre with a Klip, which is pushed over the pipe and into the insulation.

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.

On returning back to the manifold temporarilly secure the pipework; ready to make connections.

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.

TIP: The Uponor Kombi Gun; A quick and simple method for fixing Uponor MLC and PEX pipe to all common UK underfloor heating insulation boards. Item number: 1002295

SCREED:

Your floor area is now ready to be filled and pressure tested.

Once filled and tested, lay screed as soon as possible to protect the pipe. Avoid unnecessary foot traffic on the floor area until screed is completely dry.

Consult you screed supplier for drying times.

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.

50m of protective conduit suitable for 16mm pipe, Item number: 1012860

NOTE: Ensure all pipe remains below the screed floor finished level at all points. Where pipe passes through walls, ensure the pipe is sleeved to allow for expansion.

TIP: Feed pipes can be taken directly through partition walls and into their respective zones to reduce congestion.

First Fix Plumbing & Wiring withWater Temperature Control

Adding to an existing system.

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.

NOTE: Two port zone valve supplied by others if required.

First Fix Plumbing

The zone valve should be fitted on the pipe work between the boiler (on the positive side of the primary pump) before the manifold.

We suggest the following sizes and pump settings:

First Fix Wiring

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.

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.

Position the thermostats in each zone, out of direct sunlight and away from other heat sources or draughts.

Each digital wired thermostat needs be wired back to the zone controller, which should be positioned above the manifold.

Optional floor sensor, for digital wired thermostat, is supplied c/w 4m length of 2-core cable.

CAUTION: All wiring must be completed by a competant person and must comply with current IEE regulations.

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.

Filling & Pressure testing

FillingPrior 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.

• 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.

• 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 all underfloor heating loop flow and return valves on the manifold.

• 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 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.

• 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.


27

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.

• 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.

• 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.

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.

• Adjust the circuit flow rates by adjusting the flow regulators (topmeters) -see following pages.

• Pump settings:

• Typical loop flow rates, for varying loop lengths and Floor output [W/m2] are shown on the table at end of this chapter.

System Start Up

System Start-Up

When the system has been connected to the heat source and all pumps, controls, valves and bypasses fitted, the system

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.

• If removed, refit all thermal actuators.

• With the electric power off, initially set all room thermostats 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.

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.

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.

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.

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.

Frequently Asked Questions


35

Floor CoveringsCareful 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.

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.

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)

• 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).

MaintenanceThe 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.
