Uponor underĂ&#x;oor heating systems Ă? healthy, comfortable and energy-efĂžcient UnderĂ&#x;oor heating systems have ceased to be luxury, but are nowadays a convenience that you can conĂždently take for granted. First of all, underĂ&#x;oor heating is healthy. Hardly raising any dust, it is the perfect heating system for people suffering from allergies. Secondly, the gentle radiant heat provided by Uponor underĂ&#x;oor heating systems acts directly on the body without the intermediate stage of Ăžrst warming the room air. The result: the same comfort level, but with a 2 ÂĄC lower room temperature. And this is beneĂžcial to your health, because warm feet and cool head is exactly what the human body requires. Regarding the aspects of rising energy costs and the growing importance of environmental sustainability, another advantage of Uponor underĂ&#x;oor heating systems gains particular relevance: underĂ&#x;oor heating reduces energy consumption by up to 12 % and thus not only helps to save costs. Besides, the lower temperatures on the supply side allow the use of more environmentfriendly heating system elements.

?`n^mdkodjija]\nd^ntno`h Smaller dimensions of MLC pipes are designed so that the aluminium layer neutralises the snap-back forces of the plastic material, enabling easier pipe installation with minimal effort. Structure of MLC pipe with outer diameter of 16 and 18 mm

PE-RT Adhesive Adhesive PE-RT Longitudinally welded aluminium

The basic range of Uponor products includes all system components designed for different users in a variety of applications of radiant heating and cooling; like pipes, Ăžttings, manifolds and control. Description pipe Uponor multi-layer composite pipe (MLCP) is a pipe generation that unites the advantages of a plastic and a metal pipe and therefore offers a high degree of Ă&#x;exibility and toughness, coupled with high pressure and temperature resistance. MLC pipe consists of a lap welded aluminium pipe with an inner and outer polyethylene layer. All layers are permanently bonded together by means of an intermediate adhesive layer. The PE material is noncross-linked polyethylene of raised temperature resistance according to DIN 16833. Owing to the speciĂžc form of the octane side chains in the molecular structure of the material, a similar effect is achieved when polyethylene is cross-linked. Lap welding of the aluminium pipe produces a highly reliable and lasting connection on account of the wider joint. The thickness of the aluminium layer is therefore not decisive for welding and so can be adapted to speciĂžc handling requirements.

The aluminium layer is important for heat expansion. Owing to the permanent bond between plastic and aluminium, thermal expansion is determined by the expansion factor of the aluminium and roughly corresponds to that of a metal pipe, i.e. only 1/7th of the expansion of a pure plastic pipe. This offers advantages for pipe installation, since the use of compensating points is largely unnecessary. Uponor PE-Xa pipes are made from a plastic raw material, HD polyethylene, which has a high molecular weight. At high pressure and high temperatures, chemical bonds Ă? also called cross-links - are formed between the long molecular chains in the polyethylene using the cross-linking agent, peroxide. In this

way a three-dimensional lattice is created. Thanks to that Uponor PEXa is extraordinarily strong. Uponor eval and pePE-Xa Q&E pipes have an oxygen diffusion barrier of EVOH (ethyl vinyl alcohol). This barrier consists of a layer of EVOH that is extruded on the outside ofthe pePE-Xa pipe. The pePE-Xa pipes have and additional PE outermost layer. This layer is very Ă&#x;exible and does not affect the Ă&#x;exibility and pliability of the basic pipe. Uponor eval and pePE-Xa Q&E pipes fulĂžl the requirements for oxygen diffusion resistance as per DIN 4726. Uponor eval and pePE-Xa Q&E pipes are designed for heating systems where the water temperature does not momentarily exceed 95 ÂĄC or continuously exceed 70 ÂĄC. The maximum operating pressure is 0.6 MPa (6 bar). The water temperature in an underĂ&#x;oor heating system does not normally exceed 50 ÂĄC and the working pressure seldom exceeds 0.15 MPa (1.5 bar).

>\g^pg\odji_\o\ The use of calculation diagram The diagrams provide a complex overview on the inĂ&#x;uence of following parameters and joint interaction: 1. Heat Ă&#x;ow density at the Ă&#x;oor q in [W/m2] 2. Thermal resistance of surface covering RÎť,B in [m2K/W] 3. Pipe spacing T in [cm] 4. Heating medium differential temperature ΔθH = θH Ă? θi in [K] 5. Limit heat Ă&#x;ow density following limit curve 6. Floor surface differential temperature θF,m Ă? θi in [K] Calculation of heating capacity of Uponor UFH included in diagrams is carried out in accordance with European Standards for embedded water based surface heating systems. Calculation approach can be adapted (adjusted) locally according to national codes and standards. Three input parameters are sufĂžcient for estimation of all the remaining UFH system parameters by using just one diagram. A quick estimation of heat Ă&#x;ow density for the UFH system with various Ă&#x;oor coverings and heating medium differential temperatures is provided as well.

The physiological limit for maximum Ă&#x;oor surface temperature must be taken into account. The amount of heating capacity on the Ă&#x;oor surface is calculated by considering the difference between mean Ă&#x;oor surface temperature and indoor temperature in relation to the basic characteristic curve of the UFH system. Maximum Ă&#x;oor surface temperature corresponds to the limit heat Ă&#x;ow density which is determined according to EN 1264. This limit is shown in the calculation diagram as a theoretical calculation limit.

The calculation of heating capacity shall be carried out in accordance to EN 15377 Part 1 for system type G using thermal resistance method or by following national regulations with local codes and standards.

Hj_pg\mkg\nod^h\idajg_ĂŠGjjk]\g\i^dib In radiant heating systems a pressure compensation procedure must be used to ensure that all loops are supplied with the desired amounts of water.

For manifolds with flow meter this pressure compensation is carried out by adjustment of the flow rate per minute for each individual loop. (flow rate 0 Ă? 4 l/min)

For manifolds with balancing screws the setting is carried out by turning the corresponding adjustment screws.

The settings for the screws can be defined from the following diagram:

To adjust the balancing screw close the hand wheel on the supply manifold. lift the setting ring and turn it CLOCKWISE until the desired setting value is in the centre of the marker point. push the setting ring down. open the hand wheel to the stop lug

Pkjijm^jiomjgno\odjin Uponor control stations push and push Electronic as well as push 45U are pump and shunt groups designed to be used during installation of Uponor radiant heating systems. Uponor push 12, 15A/22A and 45U provides a constant supply line temperature, while Uponor push 15A/22A Electronic is equipped with an outdoor temperature compensation function. The circulation pump in the secondary circuit, is automatically controlled by the differential pressure. The speed of the pump is controlled to match the actual conditions in the radiant heating system. This means that there is, in general, no need for a by-pass in the secondary circuit. Basic design, with a constant supply line temperature, this temperature is governed by an automatic thermostat with a sensor fitted after the circulation pump.

Uponor push 15A/22A

The thermostat is continuously variable within the range 20ร55 ยกC. An integrated balancing valve and return flow inhibitor, located in the by-pass between primary return and primary supply allows to control how much of the return flow from the radiant heating loops goes back to the secondary circuit and primary circuit. Thanks to this it is possible to employ the shunt group even in small-scale systems without a primary pump.

For screeding special plastering material is required. Please contact Uponor.

When making your estimates, ensure that you also take into account such required accessories as manifolds, room thermostats and actuators, etc. All data should be checked for correctness, BEFORE the system is placed into use, by the engineer/plumber responsible for installation. Uponor will accept no liability whatsoever for any loss or damage resulting from a failure to check the guideline values for correctness with respect to the installation in question. Such liability may only be assigned in the event of gross or wilful negligence on the part of Uponor or its representatives or agents.

trating the insulation and also stops acoustical bridges from being formed.

The edging strip is to be Ăžtted before the Uponor insulation board is laid. Laying the Uponor insulation roll/ pipe Ăžxing foil The Uponor insulation roll is to be laid in preferably continuous lengths in the longitudinal direction of the room. For an easier division of the heating loops the marking frame is to concur with the side-by-side insulating lengths. Left-over surfaces in recesses, at the door passages and strips remaining on the walls are to be subsequently Ăžlled in with left-over pieces. Always place ĂŁfree-handĂ’ cut sides of the boards up against the perimeter strip to stop gaps appearing in the board laminate.

Additional insulation An additional heat insulation may be needed in keeping with the DIN EN 1264-4, EnEV or local requirements.

Pipe laying with clamp track The Uponor clamp track is to be used to fasten the heating pipes on the boards at the calculated spacing. In so doing the permitted minimum bending radii are to be kept to. The pipes must be pressed in at right angles into the clamp track. Laying can be of the meander or biĂžlar method. It could be helpful to mark supply and return of the heating loops to ensure the correct manifold connection.

Pipe laying with stapler Heating pipes are mounted onto insulation with staple nails with certain pipe spacing. Do keep min. bending radius. Two stale nails per meter pipe are required. Meander and coiled shape is possible.


Dino\gg\odjibpd_`ĂŠKdk`kjndodjidibk\i`g Insulation and perimeter strip Heat and sound impact insulation A suitable insulation which meets the requirements for heat and impact sound insulation has to be installed. Only such insulation materials are to be used which meet the standards as well as the specific construction and quality assurance regulations. When using conventional insulation materials, one has to pay attention that with multi-layer insulations a maximum of two layers consists of impact sound insulation materials. The compressibility of all insulation materials must not exceed 5 mm. When combining heat and impact sound insulation boards, the insulation with the lesser compressibility must be installed on top. The insulation layers have to be installed as a compound and butted tightly. Different layers have to be installed in a staggered way.

Edging strip Fix the edging strip with the selfadhesive strip on the backside so that the integrated breaking points show upwards. The edging strip is continuously fixed on the wall and reaches from the concrete floor up along the complete floor structure. The strip must be unbrokenly installed along the walls, door frames, pillars or steps.

The PE foil of the edging strip is laid on top of the insulation.

Transition to areas without pipe positioning panel In areas without pipe positioning panel, e. g. in front of the heating manifold, in doorways and in areas with expansion joints, the insulation has to be covered with the 0.2 mm thick PE foil. In the transition areas, the pipe positioning panel laid on top has to overlap the PE foil by at least 250 mm. The PE foil can be fixed on the insulation using the Uponor foil nail.

Attention: In an ambient temperature below 0 ยกC or above 35 ยกC it is recommended to cover the complete insulation with the 0.2 mm thick PE foil. At the joints, the foil should be overlapped by 80 mm. clear areas, where no pipe positioning panel is installed fixation of the foil with the foil nail area to be covered with the pipe positioning panel

The pipe positioning panel is laid on top of the PE foil (overlapping approx. 250 mm). At the transition, the pipe positioning panel have to be fixed on the insulation using the fastening nail.


Dino\gg\odjibpd_`ĂŠKdk`kjndodjidibk\i`g Installation of the pipe positioning panel The pipe positioning panel provides for positioning and fixation of pipes dimension 14 up to 16 mm, as well as for a barrier against penetration of screed and laitance into the insulation underneath. Start laying out the pipe positioning panel in the corner of the room, whereas at the wall edges the panels have to be laid on top of the PE-foil of the edging strip (approx. 10 cm overlapping). Due to the ĂŁpress-studĂ’ function, the panels can be joined by pressing one row of studs on top of another one, e. g. by stepping on the joint row. The punch-out of one stud at the edge of the panel prevents a multiple overlapping when joining the panels. Cut the panels to size at the edges of the room. The offcut can be used to start with the next row, whereas the panel can be turned by 180ÂĄ if required for the joint. In order to prevent the panels from lifting from the insulation in the room corners when the pipe is installed, the pipe positioning panel have to be fixed on the insulation using the fastening clip. For fixing the panels on the insulation, the pipe positioning panel shows special markings.

7

Joining of the pipe positioning panel The pipe positioning panel can easily be joined due to the ĂŁpressstudĂ’ function.

8

In case of 45ÂĄ angled walls, the pipe positioning panel can also be cut diagonally.

9

Offcuts can be integrated anywhere in the installation.

Cutting the panels to size Using a conventional blade knife the pipe positioning panel can be notched and then broken off. The pipe positioning panel can be joined at any point.

Dino\gg\odjibpd_`ĂŠKdk`kjndodjidibk\i`g Pipe installation with pipe positioning panel With the pipe positioning panel, pipes 14 x 2 mm up to 16 x 2 mm can be installed. For an easier installation, we recommend to use the pipe uncoiler. The length of pipe in a heating circuit should not exceed 120 m. Install the heating circuits according to the design layout. The pipe can simply be uncoiled by hand or using the pipe uncoiler. Simply press the pipes between the stud rows with your foot. Necessary pipe bends can be made by hand. The smallest admissible bending radius must be kept. This bending radius corresponds to a 180ÂĄ bend over 3 stud rows. The 6 cm installation pattern of the pipe positioning panel provides for pipe distances of 6, 12, 18, 24, 30 cm and larger. Attention: In case the pipe gets snapped or damaged otherwise, that piece has to be replaced by a permanently tight press or screw/compression coupling immediately. In the same manner, the pipe can be extended. The metal fittings have to be protected from corrosion. The heating circuits have to be designed in a way that no expansion joints are crossed.

Diagonal installation With the Uponor clip 14/16, the pipes can also be installed in a diagonal way on the pipe positioning panel. The Uponor clip 14/16 is simply pushed into the clear area between the studs of the pipe positioning panel where a special marking is shown. Shorter pipe lengths like e. g. in doorways or in front of the manifold do not have to be fixed.

Connection of pipes to the manifold The pipe end on the outside of the coil is led under the pipe guiding track of the manifold cabinet. The pipe has to be pre-bent carefully before guiding it into the manifold cabinet in order to avoid damaging. The adjustable screed shield can be removed for that and put back on after all pipes have been inserted. Cut, centre and bevel the pipe as described in the fitting instructions. Then connect the pipe to the heating manifold using the Uponor compression adapters.

Expansion joints In case expansion joints are required, e. g. in doorways, the supply pipes crossing the expansion joints have to be covered with the longitudinally slit Uponor joint protection tube. Then the expansion joint is produced by pressing the 10 mm thick and 100 mm high PE foam joint strip into the joint profile which has been taped onto the PE foil covering the area without pipe positioning panel.

Dino\gg\odjibpd_`Ă&#x160;Gdbcor`dbcok\i`g On-site conditions Floor construction It is very important that the existing floor is clean and level. Smaller bumps can be levelled out with conventional filler. In case of larger bumps, a levelling compound (e. g. Fermacell¨ or Perlite¨) should be used. Between the levelling compound and the lightweight panel, pressure resistant load distribution panels have to be laid. It is important that the panels used are suitable and certified for this purpose. Please consult the manufacturersĂ&#x2022; instructions for dry flooring elements. Sealing of the building Constructions adjacent to soil have to be permanently protected against moisture penetration into floors and walls. In case solid floors (e. g. concrete floors in new buildings) contain residual moisture, the rising of moisture into the dry original floor structure has to be prevented by a PE foil (0.2 mm). Please consult the manufacturersĂ&#x2022; instructions for dry flooring elements. Expansion joints Above construction joints, expansion joints have to be integrated in the dry flooring layer. Furthermore, only edge joints (edging strip) are required when installing the lightweight panel in connection with dry flooring panels (e. g. Fermacell¨ or Perlite Perlcon¨-TE) in rooms up to 20 m length. Please consult the manufacturersĂ&#x2022; instructions for dry flooring elements.

34

Before laying out the basic components, the underground surface has to be clean and level. Height variations have to be levelled out.

2

Insulation Thermal insulation / additional insulation The 25 mm thick basic component has a thermal insulation resistance of RhS = 0.62 m2 K/W. If the local standards require other thermal resistance this value can be achieved by laying an additional polystyrene insulation board (thermal conductivity rating 040) underneath the basic element. In renovations, already existing insulations in the floor structure can be considered for the layout. In connection with dry flooring panels, only insulation materials with high density must be used (e. g. polystyrene PS 30, wood fibre insulation panels make Pavatex, type Pavapor or extruded PUR).

Fix the edging strip with the selfadhesive strip on the backside so that the integrated breaking points show upwards. The edging strip is continuously fixed on the wall and reaches from the concrete floor up along the complete floor structure. The strip must be unbrokenly installed along the walls, door frames, pillars or steps. In case of multi-layered insulation, the edging strip has to be installed prior to the basic elements.

Impact sound insulation With the lightweight panel e. g. in connection with dry flooring panels on solid floors, the impact sound transmission can be reduced by up to 22 dB. Further impact sound insulation, which might be additionally required, has to be adapted to the existing floor structure. Please consult the manufacturersĂ&#x2022; instructions for dry flooring elements (e. g. Fermacell¨ or Perlite Perlcon¨-TE). In connection with Fermacell¨ also wood fibre panels 17/16 (make: Pavatex Pavapor with a weight of 150 kg/m3) can be used. When using cement or self-levelling screed, the required impact sound insulation can be achieved by adding a layer of suitable thermal and impact sound insulation material underneath the lightweight panel. The thermal and impact sound insulation panels are laid in a staggered way to the basic elements on top.


Dino\gg\odjibpd_`Ă&#x160;Gdbcor`dbcok\i`g Installation of basic elements

Lightweight panels along the walls have to be pushed underneath the foil of the edging strip.

The lightweight panels have to be laid on the complete surface of the room.

If necessary the lightweight panel can be cut by using a blade knife.

The lightweight panels in different rows have to be laid without any shift between the grooves for the pipe.

35


Dino\gg\odjibpd_`Ă&#x160;Gdbcor`dbcok\i`g Installation of heat emission plates

The heat emission plates are pushed into the grooves of the lightweight panel. In places where a pipe bend has to be realised a distance of 9 cm between the heat emission plate and the angular point of the pipe bend has to be kept.

The heat emission plates have 2 predetermined breaking points. They can be separated into different lengths by repeated bending at these points.

Installation of the pipe Push the 14 mm PE-xa pipe into the grooves of the heat emission plates with your foots. Note: Please wear sturdy shoes

Connection to the manifold In front of the manifold additional grooves can be cut into the lightweight panel using a polystyrene cutter. Note: The manifold should be installed in a central location. Thus heating loops can be connected from different directions

Screed / Dry flooring panels When using screed (cement or self-levelling screed), the lightweight panel has to be completely covered with a 0.2 mm thick PE-foil. This foil serves as separation layer. The individual foil webs have to overlap by at least 5 cm. When using self-levelling screed, the joints of the foil have to be taped. In order to prevent the penetration of screed or screed water at the edges, the PE-foil of the edging strip also has to be taped on the separation foil. In case dry flooring panels (e. g. Fermacell¨ or Perlite Perlcon¨-TE) are installed as load distribution layer, the separation foil is not necessary. When using screeds, the system has to be heated up according to DIN 4725. Please see heating report.

36


Dino\gg\odjibpd_`Ă&#x160;C`\o`hdnndjikg\o` ajmrjj_`iĂ&#x2122;jjm Wooden suspended floors do not conduct heat as efficiently as concrete. Therefore in this type of installation heat diffusion plates are required in order to achieve an even floor temperature.

Chipboard or parquet

Ensure that the wood is properly dried (maximum humidity content 10%). The following guidelines are general and are based on a centre distance between joists of 600 mm (they are also applicable to centre distances of less than 600 mm).

Vapour barrier under Uponor heat parquet emission plate

Insulation

Battens minimum 22 x 95 mm with a pitch of 150 mm

Nail battens measuring at least 22 x 95 mm using two nails to each joist (use hot zinc coated nails preferably). The first batten should be nailed approx. 50 mm from the outer wall so that the aluminium plate can be positioned correctly. Leave half the distance between the two last joists free of battens. Another batten is then laid along the last joist by the cross wall. Ensure that there is enough room left to allow for the positioning of the pipe loops . Lay the heat diffusion plates starting from the outer wall. Leave 300 mm free from the cross wall in order to allow the pipe to loop around. Cover as much as possible of the area with the diffusion plates (70 - 90 %). The diffusion plates

Floor joist

can be divided and adapted to room length. The gap between the plates should be at least 10 mm but not more than 100 mm. Pin the plates onto the battens ensuring that the pipe grooves are in alignment. Position the pipes according to the layout pattern. Lay a vapour barrier as required. Mark the routing of the pipes in order to prevent accidental perforation with screws. The chipboard (minimum thickness of 22 mm) is then laid across the battens in 600 mm sections and fixed with screws. Tongues and grooves are glued.

When laminated parquet is laid directly without chipboard beneath, the following should be observed: The structure must be reinforced. The battens must be at least 28 x 70 mm. They should be laid allowing for a gap of 25 - 30 mm to the wall and should be nailed to all the joists except for the last one. Then the ends of the battens should be lifted whilst the pipe loops are slotted round and underneath them before the nailing process is completed, the laminated parquet is laid across the battened area. Note that the battens should be nailed with hot zinc coated nails and that every fourth batten only need be nailed.

Load-bearing subsoil

Uponor pipe positioning panel with a PE-Xa 9,9 x 1,1 mm provides pipes mounting with spacing by 5 cm steps, in lateral and diagonal direction.

Insulation regulations acc. to DIN 18560 and EN 1264. The existing load distribution layer and the newly applied Ă&#x17E;lling compound must allow linear expansion (edging strips). If the subsoil does not meet the requirements of DIN 18202, it must be levelled using an appropriate Ă&#x17E;lling compound. The subsoil must be solid, load-bearing, clean, skid-proof, free from parting substances and dry. The load distribution layer must be checked and any cracks must be repaired. Wax and similar layers should be removed mechanically, Ă&#x;oor boards must be mounted properly and old Ă&#x;oor coverings such as linoleum, carpet or laminate should be completely removed without leaving a residue.

Screed Vacume clean the surface before feeding levelling or screeding compound. Follow instruction of compoundsĂ&#x201D; manufacturer; initial heat up min. 7 days after feeding screed. Use only special screed, please contact Uponor.

M`kjmon Pressure air test Note: Only a piping system incl. connections can be pressure tested by an air or inert gases. Instruments, expansion vessel, Uponor manifoldĂ&#x201D;s valves, riserĂ&#x201D;s valves and special components cannot be pressure tested with air. Safety of persons and goods during the testing is a fundamental requirement. The testing is to be conducted only with a responsible specialist which obtained knowledge about the testing device. Hints to an air pressure test A split into small testing steps (small pressure/ liter-product) offer a high safety and test accurancy. On the manometer all the leakages will be detected quicker than by extensive steps and potential points of leakage will faster located Testing time min. 30 minutes for a total pipe volume up to 100 l. Every aditional 100 l will extend the testing time by 10 minutes. Expansion of pipes will require an addition pumping of the pressure. Temperature variation and steady state is monitored. Then after the pressure test is carried out. The tightness will be determinated through observation of the pressure drop between the start and end of the testing. Common Ă&#x;uctuations caused by medium (air) temperature and the pressure of manometer are not considered as a pressure drop. The tightness testing is conducted with 0,11 bar and strength testing with minumum 3 bar.

M`kjmon Heating report Heating report for Uponor underfloor heating systems (functional heating) for anhydrite and/or calcium sulphate screed and cement screed, used with radiant heating as per DIN EN 1264-4 Person responsible/Project: Section/Floor/Room: Anhydrite and/or calcium sulphate and cement screed, should be heated up before the floor covering is laid. Procedures require that the heated floor structure should not be heat tested for correct functioning for the first 21 days after laying, in case of cement-based screed, or 7 days for anhydrite and/or calcium sulphate screed (or as per supplierÕs instructions). Testing involves maintaining the supply temperature at 25 ¡C for three days, followed by four days at maximum supply temperature. The leak resistance of the loop should be determined, by means of water-pressure testing, both immediately before and during the screed laying process. Any supplier data that differ from those contained in this report and/or DIN EN 1264-4 (e.g. for liquid screed) must be taken into account. 1.
