Set-up and configuration Wallheating and cooling systems in dry construction applications(Roth ClimaComfort Panel System)Surface temperatures during operation: Maximum surface temperature in heating mode: 40 C Recommended surface temperature for optimalcomfort: approx. 33 C Minimum surface temperature in cooling mode: 19 C Maximum inlet temperature: 50 C The usual inlet temperatures in cooling mode donot present a problem to wall plasters. Dew pointmonitoring stops condensation forming on walls andprevents moisture damage. The size of the Roth manifold needs to be determinedand somewhere chosen to install it. When makingthis decision, it is important to think about the pipeguidance between the Roth manifold and the Rothwall heating and cooling system. In most cases, theconnecting pipe to the Roth wall heating and coolingsystem is run via the floor structure.The following points must be clarified before installing aRoth wall heating and cooling system: The heat requirement needs to be determined basedon the heating load under DIN EN 1264. The valuesbased on the adjusted heat requirement should beused when devising the heating surfaces. The Roth wall heating and cooling system should beselected to suit the building specifications for the typeof object involved (e.g. new or old building). A decision needs to be made about the structure ofthe walls, including any proposed wall coverings likewallpaper or tiles. The required operating temperature for the Rothwall heating and cooling systems needs to becalculated, based on the heat flow density. Plans willneed to be corrected if the operating temperaturesare higher than required or capable of damagingindividual components. In such cases, improvedbuilding insulation can reduce the heat requirementor the proportion of the wall surface available toaccommodate the Roth wall heating and coolingsystems can be increased in order to reduce the heatflow density required. CoolingDuring cooling, it is important to ensure the coolingsystem operates within an average temperature rangeabove the dew point temperature.Based on a dew point temperature of 18 C, forexample, and an inside temperature for cooling systemsof 26 C, the temperature difference between theroom and the average cooling water temperaturewould be around 8 C. In many cases, maintaining anadequate margin above the dew point will also satisfyphysiological requirements.Generally speaking and depending on the requirementsand conditions outside (the temperature outside andrelative air humidity), the cooling water temperatureshould lie between 16 C and 19 C. It is important toensure the temperature does not fall below 16 C toavoid the risk of condensation.The Roth dew point monitor in Roth Ex heat pumpsoffers some protection, as do controls in individualrooms.10

Set-up and configuration Wall-basedenergy distributionwould have to be included in the plans. Insulating wallcoverings reduce the performance of wall heating orcooling systems, so should be ruled out at the planningstage.With larger rooms, it makes sense to fit the wall heatingand cooling system to 2 opposite walls, since the radiatingeffect on the body decreases with the square of thedistance. It is important to consider seating and howa room is divided and set out when arranging energydistributing surfaces, as well as the impact of any glasssurfaces.The Roth manifold should be used to ventilate the Rothwall heating and cooling system. Alternatively, someother ventilation option can be arranged above the Rothwall heating and cooling system.It is also important when planning wall heating or coolingsurfaces to consider where any wall-mounted fittings likeshelves or wall cupboards are to be attached. The wallheating and cooling system should not extend to theseareas, as cupboards or items of furniture can prevent theenergy-distributing surface from delivering heat or cold.Otherwise, any possible attachment or drilling pointsThe number of heating circuits will depend on thesize and nature of the wall heating surface, the pipedimensions, and the number and nature of any wallrecesses (such as doors and windows). Insulation With renovation projects, a heat transfer coefficient 0,45 or 0,35 W/m2 K applies to external walls as perEnEV. The requirements associated with the EnEV energyperformance certificate may also needed to be takeninto account.The entire insulation structure for the heating andcooling systems should be tailored to the building'sspecific requirements.As far as wall heating and cooling systems areconcerned, it is not compulsory to apply a layer ofinsulation to separating walls between rooms withsimilar heating requirements. It makes sense to do so inenergy terms, however, to avoid heating the whole ofthe wall unnecessarily. It also makes it easier to controlthe temperature within individual rooms.Insulation is always applied to separating walls betweendifferent residences. Note: In terms of selecting insulation structures, werecommend compliance with the minimum requirementsbased on DIN EN 1264. The designer will specify anyrequirements based on the building as a whole in thelight of EnEV. Interiorinsulation for external wallsIt is also worth remembering that rooms where theexternal walls have been insulated from the inside heatup more quickly, since the bulky sections of the externalwall do not need to heat through.This means rooms can be used and heated for shortperiods only without long waits for the heat to 'kick in'.During energy-related renovation work in existingresidential buildings, it is often impossible to provideinsulation from the outside via a composite thermalinsulation system. This may be the case in the followingsituations: T he facade of the building is listed or the existingdesign features need to be retained (exposedmasonry). N earby buildings or insufficient clearances makeexternal insulation impossible. The insulation measure can only be carried out inindividual residences or spaces (owner-occupiedproperties, etc.). T here is an option to convert cellar areas intoresidential or 'hobby' rooms.11

Set-up and configuration Drivingrain protectionplasterwork is 0,1 kg/m2h or better, since the wall willnot be able to take up any critical levels of moisturefrom the outside. Modern, commercially available paintsused on facades meet this requirement. Where singlelayers walls consisting of brickwork or natural stoneare involved, the building should undergo a specialistmoisture assessment based on dynamic simulations.Any damage to the facade of single-layer externalwalls (damaged and cracked plaster, broken cementin exposed masonry) must be remedied. The externalplasterwork must be sufficiently impermeable to drivingrain when fitting the ClimaComfort panel systemto single-layer external walls. There should be nomoisture-related problems if the w value for the external Vapourbarrier filmBelow a certain temperature (the dew pointtemperature) the water in the ambient air or in buildingmaterials in the form of water vapour starts to condenseor 'dew' on the surface of components, at the edges ofcomponent layers, or even across wide areas of buildingmaterials. Even before the dew point temperature isreached there may be some 'moistening' on the surfaceof components, which can cause mould to form inplaces like the corners of rooms and window reveals.The vapour barrier is supposed to prevent moisturepassing through walls or roofs. If any of the moisture inthe warm ambient air is able to pass unobstructed ontothe cold external wall, it will condense there and causemoisture damage or even frost damage.Vapour pressure curve(interior insulation)Vapour pressure curve(interior insulation with vapour block)2500200020240100Attaching a vapour block/barrier on top of the interiorinsulation inside a room keeps the vapour on the 'warm'side and prevents the construction suffering frommoisture damage.

The dry construction element caneither be secured inside the wall through the insulationor to the floor and ceiling as an attachment.The advantage with diffusion-open insulation is the waythe open-pore structure can take up moisture from aroom and release it again. This kind of insulation doesnot need a vapour barrier film, since any water whichcondenses is taken up by the insulation. Lininginternal wallsInternal walls do not require additional insulation or avapour barrier if the rooms are used in similar ways. Theinsulation properties of the ClimaComfort panel alreadysatisfy the minimum requirement (Rλ 0,75 m² K/W) forinsulation between rooms used in similar ways.13
