Introduction 1.1. SANHA wall panel heating module With its wall panel heating module, SANHA presents a completely new system for room heating and room cooling which is distinguished in particular by extraordinary domestic comfort, very simple installation, substantially improved energy efficiency due to a lower average room temperature, and especially health-friendly properties. This system is ideal both for new buildings and for the restoration of existing buildings. Wall panel heating modules are supplied in ready-to-install condition and with surfaces that can be directly painted or wallpapered Sectional view of the wall panel heating module The SANHA wall panel heating module is a finished product that is fitted in a similar way to a panel radiator. It comprises a galvanised sheet-steel frame in which a multilayer composite pipe (PE-RT/AL/PE-HD) is routed and encapsulated in a specially formulated thermal mortar.

A maximum heat output of 210 W/m² can be achieved. Modules work in the low-temperature range (max. Tv 60 C) Wall panel heating modules can be fitted to masonry walls, timber walls, drywall constructions and even to pitched ceilings (see also ) Modules fit vertically or horizontally and with the connections at the bottom or at the top 4 different lengths enable practically any combination Wall panel heating modules integrate into or completely replace conventional radiator systems Substantially improved energy efficiency With radiant heat, the average room temperature can be kept around 3-4 C lower with no loss of comfort. This alone means a 15-20% saving on heating costs The wall panel heating modules not only combine with all conventional heating systems, they are ideal in conjunction with modern solutions such as heat pumps, etc. Low-temperature heating receives a better score in the energy performance certificate than conventional radiators Thanks to the rapid heating response, heating temperatures can be regulated more or less on-demand Fantastic health-supportive properties Wall panel heating modules are good for allergy-sufferers because hardly any convection occurs and so there is hardly any lifting of dust Heated walls mean drier walls, which prevents the harmful mould growth common in modernised old buildings Besides the health benefits, this also provides important protection for the building fabric Radiant heat combats unhealthy, dry indoor air The ecologically valuable materials that we use are from natural, local sources and thereby contribute to healthy living 5 2. Planning 2.1. General Field of application New SANHA wall panel heating modules are suitable for new builds and the renovation of old buildings. They can be used as a heating system in their own right or, if necessary, they can be combined with other surface heating systems and/or conventional heating systems. Where the necessary prerequisites are fulfilled, modules also support surface cooling Placement SANHA wall panel heating modules can be fitted vertically or horizontally by use of the appropriate fastening kits. Installation on masonry is possible and also compatible with timber walls or metal studwork. Modules can be fitted to periphery and internal walls (subject to local thermal efficiency codes). Module installation on ceilings pitches of at least 45 is also easily possible. 45 Mounting rails Parallel and series arrangement Where multiple modules are to be fitted in the same room, modules can be arranged in parallel or in series. Parallel arrangement For the parallel arrangement, it must be ensured that each module has its own isolating valve. The isolating valves must also be equipped with a control valve and drain-off/flushing point so that hydraulic balancing and bleeding/flushing can take place.. Series arrangement With a series arrangement, only one central isolating/control valve and drain-off/flushing point will be required for the modules in this group. In the pipe network calculation and during hydraulic balancing, a greater pressure drop and the higher resistances of the connecting lines and fittings should be taken into consideration. Resistance factors and pressure drops for MultiFit -Flex pipes and 3fit -Press fittings can be found in the technical tables at chapter 2.2. PLANNING Building prerequisites To avoid stressing of the modules, the wall placement surface must meet the requirements of DIN in respect of angle and flatness tolerances. Uneven walls can be levelled off by means of a light-duty wall substructure, levelling battens or a levelling compound. To bear the modules, the substructure must offer sufficient strength and rigidity as recommended by DIN The wall placement surface must be suitable for bearing load and be free of impurities and loose parts. Electrical and sanitary installations in the wall must be self-contained and installation recesses must be filled. Care must be taken to avoid existing pipework and electrical wiring in the wall. If possible, modules should be fitted before screeding takes place so that the branch pipes can be routed under the screed Thermal insulation In the case of periphery walls, local thermal efficiency codes may impose requirements for insulation performance. In Germany, for example, no additional insulation measure is required if the U-value of the periphery wall is above 0.45 W/m²K. No additional insulation is required in the case of internal walls. Thermal transfer to unheated rooms should be taken into consideration Design Technical specifications of SANHA wall panel heating modules Frame Heating pipe Filler Coating Reinforcement Joining technology Operating temperature Operating pressure 0.75 mm galvanised sheet steel SANHA Multifit -Flex multilayer composite pipe, 16 x 2 mm (PE-RT/AL/PE-HD), max. 95 C/10 bar, oxygen-tight in accordance with DIN4726 Lime/cement/mortar with natural additives and carbon, Dry density: 1070 kg/m³ Cardboard Fibreglass SANHA 3fit -Press press connector or 3fit -Push system Max. 60 C (heating) Min. 16 C (cooling) Max. 10 bar Type 750/ / / /625 Dimensions (HxWxD) 750 x 625 x 25 mm 1250 x 625 x 25 mm 2000 x 625 x 25 mm 2500 x 625 x 25 mm Heating surface 0.47 m m m m 2 Heating pipe length 4.7 m 7.8 m 12.5 m 15.6 m Water capacity 0,53 litres 0.85 litres 1.41 litres 1.76 litres Weight approx. 19 kg approx. 31 kg approx. 50 kg approx. 63 kg Power and pressure drop data 1WH75 modul size W x H 62,5 x 75 cm HEATING HEATING δi = 20 C δ V δ R Number of modules arranged in series δi = 22 C δ V δ R Number of modules arranged in series In the data for modules circuited in series, the pressure drops for the connecting line including fittings have already been factored into the values given.

With an embedded installation, e.g. integrated into a drywall construction or with the voids between modules filled out, a wall box such as Oventrop Unibox T is recommended. This is an individual room control unit installed on the supply side. The temperature is regulated by a thermostatic head as with a radiator. The bottom edge of the Unibox should be at least 20 cm above the finished floor and be easy to access. The thermostatic head must not be exposed to direct sunlight. On the return side, it is also possible to fit a wall box such as the Oventrop Unibox RLA with combined isolating and control function. For cooling operation, a unit such as the Oventrop Unibox E TC is recommended. This allows the thermostat setting to be changed for cooling. In this position, the thermostat is fully open Individual room control by heating circuit distributor A heating circuit distributor is used to distribute heating or cooling water to the individual heating circuits. The heating circuits can be regulated by means of servomotors on the heating circuit distributor. The servomotors are controlled by the room thermostats in the individual rooms. The room thermostat should be located in a convenient place, e.g. next to the light switch at the entry to the room. Exposure to direct sunlight must be avoided. Room 2 Room 3 PLANNING Individual room control in combination with radiators SANHA wall panel heating modules can be used successfully in conjunction with existing radiators as part of old building renovations or in combination with radiators in new build projects. The maximum permissible flow temperature for the modules is 60 C. Where the design temperature of the radiators is higher, the modules can be controlled by means of a return temperature limiter unit such as the Oventrop Unibox RTL Individual room control in combination with underfloor heating SANHA wall panel heating modules are also extremely effective in conjunction with the existing underfloor heating in old building renovations or new build projects. The modules are plumbed into the supply side of the underfloor heating circuit. The temperature is then controlled by a thermostatic valve with Kvs value setting. For return flow isolation, a combined isolation, control and drain fitting is used. The module group-underfloor heating sequence can also be swapped. 15 3. Installation For transport and installation of SANHA wall panel heating modules, up to 2 persons may be required, depending on module size Storage and transport On the construction site, SANHA wall panel heating modules should be treated like plasterboard, particularly with regards to keeping them dry. The modules must not be set down on their connection pipes. Modules are delivered on pallets. During transport of individual modules, care must be taken to avoid flexing. They should therefore be transported upright. Each module bears a label with the relevant information. This label should be removed at the time of installation Step-by-step guides to safe, quick and easy installation For safe, quick and easy installation of wall panel heating modules, SANHA offers a selection of prepacked fastening kits containing the necessary screws and wall plugs. As appropriate to the mounting surface, separate kits for installation on masonry, timber walls and drywall constructions are available. Step-by-step instructions for each type of mounting surface are provided in this section. The mounting surface must be sufficiently strong and flat (see also 2.1.4). Product liability claims cannot be accepted unless our fastening kits have been used correctly. For new builds, it is recommended that the connection pipes be routed inside the flooring. In this way, there would be no voids underneath the module that would need to be filled out. With old building renovation, it is possible to have the modules terminated on a special pipe duct (skirting board) so that the connection pipes are inside the duct and no voids are created underneath the modules. Installation Installation on masonry First, fit the mounting rail from the Wall panel heating module fastening kit for masonry, art. no. 1WHBSM to the wall at the desired height from the floor using the appropriate screws and wall plugs and with the aid of a spirit level to ensure horizontal alignment. Then place the module on the rail and press it back against the wall. Using a 6 mm masonry drill, drill pilot holes through the module at the marked positions to a depth of approximately 85 mm. Do not use an impact drill or any form of impacting tool to do this. Then insert the wall plugs and screw the 4.5 x 80 mm screws in to a depth of 2 cm. Using a hammer, drive the screws and wall plugs in to a depth of approximately 2.5 cm ( push-through installation ) and screw the screws and wall plugs home. The screws should finish flush with the module or be sunk to a maximum depth of 1.0 mm in the module. To conclude, fill out the holes and the butt edges Installation on metal studwork First, fit the mounting rail from the Wall panel heating module fastening kit for studwork, art. no. 1WHBST to the studwork at the desired height from the floor using the appropriate screws and with the aid of a spirit level to ensure horizontal alignment. Then place the module on the rail and press it back against the studwork. At the marked positions, pilot drill the screw holes using a 3 mm bit. Using the 4.2 x 38 mm self-tapping screws included in the kit, fasten the module at the marked positions. The screws should finish flush with the module or be sunk to a maximum depth of 1.0 mm in the module. To conclude, fill out the holes and the butt edges. Installation on timber First, fit the mounting rail from the Wall panel heating module fastening kit for timber, art. no. 1WHBSH to the wall at the desired height from the floor using the appropriate 5.0 x 50 mm screws and with the aid of a spirit level to ensure horizontal alignment. Then place the module on the rail and press it back against the wall. At the marked positions, pilot drill the screw holes using a 3 mm bit. Using the appropriate 4.0 x 60 mm screws, fasten the module at the marked positions. The screws should finish flush with the module or be sunk to a maximum depth of 1.0 mm in the module. To conclude, fill out the holes and the butt edges Installation on pitched ceilings To install modules on pitched ceilings, a minimum pitch of 45 is required and at least 3 persons will be needed (see also ). Depending on the mounting surface, installation is identical to the procedure for timber walls or drywall constructions Horizontal installation Select the appropriate installation kits for the mounting surface concerned. For wall panel heating modules WH200 and WH250, please note that it is necessary to fit a second mounting rail. This is fitted at the same height and with a gap of 300 mm (WH200) or 500 mm (WH250) from the first rail. For the remaining steps, proceed as for vertical installation Additional drilling surfaces If the marked screw positions are unsuitable (e.g. installation on pitched ceilings), it is possible to drill elsewhere without damaging the pipes. The exact positions of the available drilling surfaces are shown in the diagram. Drill and screw surfaces Supply Return Height 750 / 1250 / 2000 / 2500 Installation Connecting the supply and return lines With a view to complying with the terms and conditions of the system guarantee, only genuine SANHA products from the 3fit -Press and/or 3fit -Push ranges and approved tools or clamping ring fittings suitable for 16 x 2 mm composite pipes should be used to connect the branch pipes and module connection pipes. However, if fittings of a different make of press- or push-fit jointing system are used for the branch pipes and connection pipes, compliance with the system guarantee can be achieved by keeping system-specific installation components separate. To do this, it is necessary to fit the module lines with SANHA adapter kits for press-fit jointing systems art. no. 1WHASPF or for push-fit jointing systems art. no. 1WHASSF. In this case, the transition to the other system is by means of the internally threaded connection of the adapter kit. Within the same room, SANHA wall panel heating modules are usu
