Subject to change without notice | 83054300eUK – Translation into English of the original German operating manual | ait-deutschland GmbH 5 Functioning principle of heat pump system Heat pumps operate on the principle of a refrigerator: the same technology, only with the opposite effect. The refrigerator extracts heat from foods, which is released into the room through fins on the back. The heat pump extracts heat from our environment: air, earth or ground water. The extracted heat is conditioned in the unit and supplied to the heating water. Even when it is extremely cold outside, the heat pump draws enough heat to heat a house. Heat quantity recording In addition to proof of the unit's efficiency, heating legislation also requires heat quantity recording (referred to as WME in this manual). The WME is mandatory with air/water heat pumps. With brine/ water and water/ water heat pumps, a WME is only required when the feed temperature is ≥ 35 °C. The WME must record the total warm energy release (heating and hot water) in the building. In heat pumps with heat quantity recording, the analysis is conducted by the regulator. The regulator displays the thermal energy that is exchanged from the heating system in kWh. Example: drawing of a brine/water heat pump with floor heating: Operation Your decision to purchase a heat pump or a heat pump system is a long-term contribution to protecting the environment through low emissions and reduced primary energy use. You can operate and control the heat pump system with the control element of the heating and heat pump regulator. NOTICE. 4 ⁄4 = ca. 3 ⁄4 = ca. 1 ⁄4 = usable energy environmental energy external electrical energy Area of utilisation Make sure that the control settings are correct. Operating manual of the heating and heat pump regulator. To ensure that your heat pump or heat pump system operates efficiently and ecologically, the following are especially important: € Avoid unnecessarily high flow temperatures. A lower flow temperature on the hot water side increases the efficiency of the system. Taking into consideration the ambient conditions, limits of application and the applicable regulations, every heat pump can be utilized in new or existing heating systems. Overview "Technical data / scope of delivery". 6 € ENERGY SAVING TIP ENERGY SAVING TIP When letting in fresh air, do not leave windows open for an extended period, thus saving energy and reducing your heating costs.

WATER QUALITY OF THE FILL AND ADDITIONAL WATER IN HOT WATER HEATING SYSTEMS ACCORDING TO VDI 2035 PART I AND II Use of modern, energy-efficient heat pump systems is becoming increasingly widespread. Their ingenious technology enables these systems to achieve very good efficiencies. The decreasing space available for heat generators has led to the development of compact units with increasingly smaller cross-sections and high capacities. This means the complexity of the systems and the material diversity are also increasing, which plays an important role especially in their corrosion behaviour. Alpha InnoTec ensures continuous technological advances, but all these technical refinements require the system to be operated with correctly filled heating water. The heating water not only affects the efficiency of the system, but also the life of the heat generator and the heating components of a system. The guide values of VDI 2035 Part I and Part II must therefore be complied with as minimum requirements for proper operation of the systems. Our practical Subject to change without notice | 83054300eUK – Translation into English of the original German operating manual | ait-deutschland GmbH experience has shown that the safest and most troublefree running of the systems is achieved with so-called low-salt operation. VDI 2035 Part I gives important information and recommendations regarding scaling and its prevention in heating and domestic hot water heating systems. VDI 2035 Part II primarily deals with the requirements for reducing heating water corrosion in hot water heating systems. WATER SOFTENING TO VDI 2035 – PART I If the water is softened before the heating is filled, in accordance with the VDI 2035 guidelines, no scale can form. This effectively and permanently prevents limescale deposits and the resulting negative effects on the entire heating system. CORROSION – AN UNDERESTIMATED PROBLEM PRINCIPLES OF PART I AND PART II The occurrence of scaling and corrosion damage in hot water heating systems is low, if - proper planning and commissioning is carried out - the system is closed in corrosion terms - adequately dimensioned pressurising is integrated - the guide values for the heating water are complied with - and regular servicing and maintenance are carried out. A system log should be kept, in which the relevant planning data is entered (VDI 2035). DAMAGE THAT CAN OCCUR IN CASE OF NONCOMPLIANCE - Malfunctions and the failure of components (e.g. pumps, valves) - Internal and external leaks (e.g. from heat exchangers) - Cross-section reduction and blockaging of components (e.g. heat exchanger, pipes, pumps) - Material fatigue - Gas bubbles and gas cushion formation (cavitation) - Negative effect on heat transfer (formation of coatings, deposits) and associated noises (e.g. boiling noises, flow noises) LIMESCALE – THE ENERGY KILLER Filling with untreated drinking water inevitably leads to the precipitation of all calcium as scale. The consequence: limescale deposits form on the heat transfer surfaces of the heating. The efficiency falls and the energy costs rise. A rule of thumb is that 1 millimetre of limescale deposit causes an energy loss of 10%. In extreme cases it can even cause damage to the heat exchangers. VDI 2035, Part II, deals with the problem of corrosion. Softening the heating water can prove to be insufficient. The pH value can significantly exceed the limit of 10. pH values higher than 11 can set in, which even damage rubber seals. The VDI 2035, Part 1 guidelines are fulfilled, however, VDI 2035, Part 2 suggests a pH value between 8.2 and maximum 10. If aluminium materials are used, which is the case in many modern heating systems, a pH value of 8.5 must not be exceeded, because otherwise there is a threat of corrosion – and aluminium is attacked without the presence of oxygen. Therefore, apart from softening the heating fill and additional water, the heating water should also be appropriately conditioned. This is the only way to comply with the VDI 2035 requirements and the recommendations and installation instructions of the heat pump manufacturer. Part 2 of VDI 2035 also points out the reduction in total salt content (conductivity). The risk of corrosion is far lower if deionised water is used than is the case if the system is operated with salty, i.e. softened water. Even if the water has been softened beforehand, it contains dissolved, corrosion-promoting salts, which act as electrolytes due to the use of different materials in the heating system and therefore accelerate corrosion processes. This can ultimately result in pitting. Contamination and deposits in the heating circuit can cause malfunctions RINSE, FILL AND BLEED THE HEATING CIRCUIT AND HOT WATER BUFFER TANK To bleed the hot water tank, the heating circuit and hot water circuit must be rinsed simultaneously. ON THE SAFE SIDE WITH LOW-SALT OPERATION The problems listed above do not occur at all with low-salt operation, as neither corrosive salts such as sulphates, chlorides and nitrates nor alkalising sodium hydrogen carbonate are in the heating water. The corrosive properties of deionised water are very low and in addition, fur cannot form in the boiler. This is the Subject to change without notice | 83054300eUK – Translation into English of the original German operating manual | ait-deutschland GmbH 19 ideal approach for closed heating circuits, in particular, because low oxygen input into the heating circuit can also be tolerated. In general, when the system is filled with deionised water, the pH value sets itself within the ideal range due to “self-alkalinisation”. If necessary, a pH value of 8.2 can be very easily alkalised by adding chemicals. In this way, optimum protection of the entire heating system is achieved. Insulating the hydraulic connections Insulate the vibration decouplers and the pipes of the heating circuit. NOTICE. Insulate in accordance with applicable local standards and directives.
