Introduction

6/7 Saving energy and protecting the climate Viessmann is aware of its responsibility for sustained protection of the environment. Its company philosophy and products focus on this. "Nothing is so good that it cannot be improved." This maxim is at the heart of the company's principles. In this industry, Viessmann can rightfully claim to be the leader in quality and technology, and as such, aims to continually set new standards. Of course, this applies in particular to the company's product range, which is consistently geared towards significantly lowering the consumption of fossil fuels, and gradually replacing them with renewable sources of energy. At around 40 percent, the heating market actually accounts for the largest proportion of energy consumption in Germany. The rest is shared by "goods transport", "personal transport" and "power", with 20 percent respectively. These are values that can also be applied, to some extent, to other industrial countries. Ever-rising energy costs mean the emphasis is on reducing the consumption of fossil fuels as quickly as possible and utilising these fuels as efficiently as possible. Natural heat The heating system from Viessmann Heat pumps should be your first choice if your priorities are both to save on heating costs and to generate heat in an environmentally responsible way. After all, the environment gives us an unlimited and free supply of the energy a heat pump uses. This fully competent heating system requires only the costs of electricity for the drive and pump. This makes you independent of fossil fuels, and in addition you make an active contribution towards reducing CO 2 emissions and protecting the climate. As a pioneer in the field of standard heat pumps, Viessmann has been setting standards in efficient energy utilisation and long service life for 30 years with its advanced systems. This means you also benefit from its many years of experience as a supplier of comprehensive heating systems. Whether for modernisation or new build: Viessmann has the right solution for you, too! Viessmann offers you energyefficient heating systems for oil, gas, solar, biomass and natural heat. The pictograms will help to guide you.

Introduction Simple principle, great result The technical principle of a heat pump is similar to that of a fridge it just works the other way round. In a fridge, heat is transferred from the inside to the outside. With a heat pump, this happens exactly the other way round. The heat from outside e.g. from the ground is transferred via the heating system to the inside, into the living space. To raise the temperature, a refrigerant vapour is compressed until the temperature for central and DHW heating is reached. With the Vitocal 300-G and Vitocal 350-A, this can even be up to 65 C. This means this heat pump can also be used for modernisation projects. Very efficient scroll compressor The compression process is vital for the efficiency of a heat pump. Viessmann uses a Compliant scroll compressor that comprises two interlinking scrolls that continually compress the refrigerant. As with a bicycle pump, the temperature also rises with the pressure. This ensures efficient temperature raising from the cold side (the heat source on the outside) to the hot side (the heating circuit in the building). The benefit of Compliant scroll compressors as used by Viessmann is that they operate quietly and with low vibrations, are maintenance free and extremely durable. You won t need to worry about heating bills any more An investment in a Viessmann heat pump will always be worthwhile because you won't have to pay for any more fuel from day one. From now on, the energy you use to generate heat comes free, from right outside your door. Furthermore, the power needed to use this free fuel is very efficiently used. From one kilowatt of power, a heat pump can generate between 3 and 4 kw of heat. A heat pump can make use of the following energy sources: Heat pump Air: Practically unlimited availability; lowest investment costs VITOCAL Compression process Ground: Via geothermal collector or geothermal probe; very efficient 65 C Water: Extremely efficient; observe water quality Ground Temperature all year round between 5 and 18 C (at 2 m depth) Getting hotter towards the centre from an initial temperature of between 5 and 18 C, a flow temperature of up to 65 C is achieved. Waste heat: Subject to availability, volume and temperature level of the waste heat The best heat source for each individual case depends on local conditions and the actual heat demand.

Heat pumps 10/11 VITOCAL You can either get annoyed about ever-rising energy prices or make yourself independent of fossil fuels, relying on highly developed technology instead. Vitocal heat pumps from Viessmann utilise the unlimited, free natural heat in the environment, making this heating technology amongst the most economical and clean of all options for heat generation. To ensure that this remains the case and that heat pump technology is continuously improved and therefore becomes even more efficient, Viessmann is putting innovative development and improvement at the top of its list. Only when the customer is satisfied with Viessmann heat pumps can the company be satisfied too.

Heat pumps Vitocal 300-G

18/19 VITOCAL 300-G With the Vitocal 300-G, you utilise the renewable heat from the ground or groundwater and do so in a tiny space, because this heat pump is designed to be particularly compact. Inside the casing of models BWC/WWC, the circulation pumps for the brine circuit and the heating circuit, as well as the three-way diverter valve, are already integrated. The Vitocal 300-G ground source heat pump is specifically designed for detached houses. It utilises heat that's right on your doorstep. What's more, you call the shots, selecting the output from 6.2 to 117.8 kw, making it both efficient and effective. So your central and DHW heating needs will be reliably and conveniently covered. Heat from the ground or groundwater You can choose how you get heat from the ground with the brine/water version. This is done either via a geothermal probe or via a geothermal collector laid at a depth of approx. 1.5 m. In both cases, the heat pump covers the entire energy demand, even on colder days. Subject to the location of your house, it may also be possible to utilise the latent heat in groundwater. For this, the Vitocal 300-G is simply converted to operate as a water/water heat pump and delivers the highest COP in this operating mode. Tightly packed performance The Vitocal 300-G (type BWC/WWC) proves its worth through its particularly compact design. It contains everything including circulation pumps for brine and heating circuit. Also supplied as standard: a safety assembly with safety valve, pressure gauge and air vent valve. The clever integration of these components saves space and already covers all the most important applications. An electric booster heater is available as an accessory. Greater heat demand? No problem for the Vitocal 300-G For buildings with a very high heat demand, the two-stage Vitocal 300-G based on the master/slave principle is the right choice. It achieves a heating output of 12.4 to 117.8 kw. Here, you also have the choice between the groundwater or the ground as the heat source. Vitocal 300-G is certified in accordance with the EHPA heat pump quality seal and NF-PAC.

Heat pumps Vitocal 300-G Simple user interface: The digital WPR 300 control unit with user prompts displays an overview of the system configuration with temperature details. In addition, it enables remote monitoring and remote control with Vitocom and Vitodata. Powerful, quiet and reliable The heart of the Vitocal 300-G is its powerful Compliant scroll compressor. It convinces through excellent reliability, safety and particularly quiet operation, thanks, in part, to the hermetic seal and dual anti-vibration mounts. At the same time, the Compliant scroll compressor ensures the highest performance factors and flow temperatures up to 65 C. Environmentally responsible in every respect Not only when it comes to the utilisation of renewable energy is the Vitocal 300-G set up for a fully environmentally responsible operation. It also uses a refrigerant, i.e. R 407 C, that is CFC-free, non-flammable and biologically degradable. you can link several separate heat pumps via the heating flow and return. This does not just deliver the higher heat output, but also increases the operational reliability of the entire system. The modular construction with separate compressor circuits also ensures particularly high efficiency in the partial load range, and enables simultaneous operation of central and DHW heating. RCD supplies as much heat as you need RCD stands for Refrigerant Cycle Diagnostic system. In the Vitocal 300-G, it continuously monitors the refrigerant circuit and, in conjunction with the electronic expansion valve, ensures the highest level of efficiency at every operating point. The energy statement to receive subsidies is already integrated. 1 Backup from the sun An advanced heating system should include innovative solar technology. To make use of solar energy to back up your heat pump. Viessmann offers you a system that is a perfect match for the Vitocal 300-G. Perfect for higher output levels too Even for greater heat demand, the Vitocal 300-G is the right choice, because Modular solution for higher heat demand With six output sizes as a master or slave version, various combinations can be realised, precisely matched to the required heat demand. Because of this flexibility, systems can be configured so that runtimes match demand and save you money. The master module regulates the slave module. By combining different output sizes, users have the option of matching the environmentally responsible heating system to their own heat demand as, for example, in an apartment building as efficiently as possible by utilising various modules. There is also the option to equip the entire system with high efficiency DC pumps (Energy Label A). 2 3 4 Vitocal 300-G (type BWC/WWC) 1 Safety equipment block with safety 5 6 assembly 2 Brine circuit pump 3 Heat pump control unit with user prompts WPR 300 4 Large area evaporator for an efficient heat exchange 5 Hermetically sealed Compliant scroll compressor 6 Electronic expansion valve

Heat pumps Vitocal 350-A

24/25 VITOCAL 350-A Do you want to modernise your heating system with a heat pump, but are unable to make use of heat from the ground or groundwater? No problem with the Vitocal 350-A air source heat pump. The Vitocal 350-A air source heat pump with rated heating outputs 10.6 to 18.5 kw is particularly suitable for modernisation. Thanks to enhanced vapour injection developed by Viessmann in the compression process (EVI cycle), flow temperatures of up to 65 C are achieved even at winter outside temperatures. The new air source heat pump can therefore also be used in older heating systems with radiators. The control unit (WPR 300) of the Vitocal 350-A has an integral cascade function. This means that, in buildings with a higher heat demand, up to four air source heat pumps can be operated in a cascade. Cumulative heating outputs of up to 74 kw are therefore possible. Air source heat pump with particularly high efficiency An electronic expansion valve and RCD system also ensure an extremely high level of efficiency for the Vitocal 350-A all year round. For air source heat pumps, the Vitocal 350-A offers a high Coefficient of Performance, i.e. 3.5 (in accordance with DIN EN 14511 at air 2 C/water 35 C), resulting in high seasonal performance factors and very low running costs. Space saving thanks to outside installation The Vitocal 350-A can be installed either internally or externally. The three-stage radial fan in the heat pump, as well as the flow-optimised air routing and the sound insulated casing together make the Vitocal 350-A extremely quiet and during night operation; the variable-stage fan control unit reduces the speeds and thus the noise emissions even further.

Heat pumps Vitocal 350-A Ideal for modernisation The Vitocal 350-A air source heat pump makes modernising easy. The additional vapour injection in the compression process (EVI cycle) enables flow temperatures up to 65 C. That makes it an ideal choice where older heating systems with radiators are installed. The heat pump draws its energy from the ambient air without needing to drill boreholes for geothermal probes. High DHW convenience Subject to system version, a higher flow temperature enables a water temperature of up to 55 C inside the DHW cylinder. This allows the Vitocal 350-A to deliver a particularly high DHW convenience. The Vitocal 350-A achieves the high flow temperature of 65 C even at outside temperatures of -10 C. RCD guarantees efficient operation RCD stands for Refrigerant Cycle Diagnostic system. In the Vitocal 350-A, it is responsible for permanently monitoring the refrigerant circuit. This, in conjunction with the electronic expansion valve (EEV) ensures the highest efficiency at every operating point. Alongside this, important operating parameters are saved and called up, when required, for diagnosis, optimisation, energy statements and to calculate the standard seasonal efficiency. Just perfect If the heat pump is installed outside, the heat needs to be "transported" to the interior of the house. For this, you can rely on the heating competence of Viessmann. For routing underground, you can rely on Viessmann's specially matched, thermally insulated pipe systems, as well as a complete range of accessories. 1 3 2 4 2 5 Vitocal 350-A 1 Inlet side 2 Discharge side 3 Evaporator 4 Radial fan 5 Hermetically sealed Compliant scroll compressor

Heat pumps Vitocal 300-A

28/29 VITOCAL 300-A The Vitocal 300-A opens a new chapter for modulating air source heat pumps guaranteeing the highest level of efficiency at every stage with its advanced heat pump technology. Simply taking energy out of the air and using it for central and DHW heating sounds rather tempting. However, especially in winter, i.e. precisely when the demand for heating energy is high, the outside air does not contain much energy for a heat pump to extract. However, this is no problem for the Vitocal 300-A air source heat pump. It is particularly efficient and can, even at an outside temperature of 5 C, still deliver a flow temperature of 60 C. Heating efficiently with air The Vitocal 300-A air source heat pump is extremely efficient and achieves high seasonal performance factors.

Heat pumps Vitocal 200-G

36/37 VITOCAL 200-G With the Vitocal 200-G, heating with environmental heat is not just a question of money. If you are building, or planning to build, a detached house, then Viessmann has the right heat pump solution that will win you over with its powerful output and surprise you with its price. The output of the Vitocal 200-G makes using renewables very attractive particularly for detached houses. Save yourself the heating bills An investment in a Viessmann heat pump such as the Vitocal 200-G is always worthwhile because you won't have to pay for any more fuel from day one. From now on, the energy you use to generate heat comes free, from right outside your door. Furthermore, the power needed to use this free fuel is very efficiently used. From one kilowatt of power, the heat pump generates between 3 and 4 kw of heat. A good investment for the future Durability is a key feature of all Viessmann heat pumps. The materials used must comply with the most stringent of demands, and strict quality conditions are applied right through manufacture. This will pay off for you, for example, the refrigerant circuit is hermetically sealed and therefore requires no maintenance. The environment benefits too It's good to know that heat pumps significantly reduce CO 2 emissions every day whilst they provide central and DHW heating. After all, no fossil fuels are used here. This means you protect valuable natural resources, and by purchasing a Vitocal 200-G, you also make a personal contribution to active climate protection. Two heating circuits for individual heating convenience The convenient ground source heat pump offers all functions required for using a heat pump in a new detached home. The weathercompensated, digital heat pump control unit allows two separate heating circuits to be connected. High flow temperature The innovative technology of the efficient Compliant scroll compressor allows the Vitocal 200-G to achieve a maximum flow temperature of 60 C. This means you are not tied to an underfloor heating system. You can use radiators for transferring heat into the living space and heating DHW is also more convenient. Vitocal 200-G is certified in accordance with the EHPA heat pump quality seal and NF-PAC.

Heat pumps Vitocal 200-G Full output, even in winter With its output spectrum of 6.4 to 9.6 kw, the Vitocal 200-G in mono-mode operation guarantees convenient heat supply all year round. This means even in winter when it gets really cold outside, you'll be snug and warm inside and without a booster heater. A heating system in summer? For cooling, naturally! When it's hot outside in summer, you can make the room pleasantly cool with your Vitocal heat pump. Switch to natural cooling. By simply running the circulation pumps, the heat from inside your house is transferred to the ground. All you need to use the Vitocal s handy extra natural cooling function is an NC-Box. Installation and assembly made easy The Vitocal 200-G is supplied with integral brine and heating circuit pumps, diverter valve and fitted safety assembly. Handling the Vitocal 200-G is no problem, since the casing and heat pump module are delivered separately. Installation on site is child's play, as all the connections are at the top. This also means the heat pump can be installed close to the wall without needing clearances. Optional temporary installation of an electrical booster heater, for example for screed drying, is an additional bonus. 1 2 3 4 Vitocal 200-G 1 Safety equipment block with safety 5 assembly 2 Weather-compensated, digital heat pump control unit CD 70 3 Brine circuit pump 4 Hermetically sealed Compliant scroll compressor 5 Heat pump module, fully thermally insulated

Dual mode systems Twice the benefit with dual mode heating systems Oil and gas prices continue to rise. So what should you do if you have purchased an advanced oil or gas boiler in the past few years? It's quite simple save substantially with a dual mode heating system, and at the same time reduce emissions. A heat pump is the ideal way to extend the heat supply of an existing oil or gas heating system. Consumption costs are lowered through the use of free energy from the environment, and simultaneously the dependence on fossil fuels is reduced. However, a dual mode heating system has even more benefits: Oil storage space and amount of oil to be stored can be reduced The operating times of the existing system are reduced; the service life increases The low proportion of annual heating load means the boiler is no longer subject to the yearly flue gas inspection, saving additional costs Power for heat pumps can be obtained at special tariffs The existing DHW heating system can continue to be used Little effort, great effect. You only need the following: Three-phase power supply with 400 V Installation area for heat pump and heating water buffer cylinder, approx. 4 m 2 Radiator heating system < 65 C Boiler thermostat setting max. 65 C Options for drawing in outside and expelled air when installed inside Space to install the special heat pump meter Power supply to the heat pump meter The Vitocal 300-A utilises the outside air heated by the sun and on cold days, a second heat source can be switched on automatically by the heat pump control unit.

Heat pumps Vitocal 160-A VITOCAL 160-A DHW heating with central heating Vitocal 160-A heat pump for DHW heating The Vitocal 160-A heats DHW whilst saving energy and costs. As its heat source, it uses the warm air inside the building that is always around and is therefore particularly ideal for use anywhere where heat is available in abundance, e.g. in bakeries. It can be operated completely independently of other heat sources. Compact DHW station utilises ambient heat The compact Vitocal 160-A DHW heat pump is equipped with all the components necessary for efficient and space-saving DHW heating. Together with the heat pump module (output 1.52 kw, COP = 3.54 at 15 C air temperature and 45 C water temperature), a 285 litre cylinder, a booster heater and the control unit are all integrated inside one casing. It is convenient to select the various programs using the easy-to-operate control unit with its large display. Whether for DHW heating, constant operation or standby mode the various functions can be selected by pressing just a few keys. Additional benefits of room cooling or controlled domestic ventilation As the recirculating air heat pump version, the Vitocal 160-A uses the air straight from the room in which it is installed. As an extract air heat pump, it draws in warm extract air via ducts from other rooms, e.g. the bathroom, WC and kitchen. Part of the heat from the air that is drawn in is extracted, raised to a useable temperature level with the heat pump, and used to heat the DHW. The recirculating air heat pump then returns the cooled and dehumidified air to the installation room that can then be used as a cool storage room for groceries. The air cooled in the extract air heat pump 2 3 1 is routed to the outside via an expelled air duct. In conjunction with ventilation air apertures that ensure the supply of fresh outside air to the living space, the Vitocal 160-A becomes the central component of a controlled domestic ventilation system. This makes the Vitocal 160-A suitable for modernisation too. 4 5 5 Vitocal 160-A 1 High efficiency rotating piston compressor 2 Large area evaporator for an efficient heat exchange 3 Programmed control unit subject to appliance type, with solar function 4 Integral booster heater with 1.5 kw output 5 Integral enamelled 285 l DHW cylinder

Heat pumps 44/45 Cooling with heat pumps The primary function of heat pumps is to provide pleasant and convenient heat, and reliable DHW heating. However, they can also be used to cool a building. Imagine a hot summer s day. Would you switch your heating on? Probably not, unless you have a Viessmann heat pump. After all, heating systems don t generally have much to do in summer apart from heating DHW. It is different for heat pumps, as some Viessmann heat pumps also offer a cooling function as an additional benefit. Active or passive cooling When cooling with a heat pump, you can choose between two different methods: Cooling by nature: Natural cooling While the ground or groundwater is used in winter to provide energy for heating, in summer it can be used for natural cooling. With the natural cooling function, the control unit only starts the primary pump and heating circuit pump. This means the relatively hot water from the underfloor heating system can transfer its heat in the heat exchanger to the brine in the primary circuit. This extracts heat from all rooms that are connected. This makes natural cooling a particularly energy-efficient and affordable way to cool buildings. Passive cooling: This is where the brine medium or the groundwater absorbs the energy from the heating circuit via a heat exchanger and transfers it outside. This function is also called natural cooling, as it uses the natural ambient temperature. Apart from the control unit and circulation pump, the heat pump remains switched off. Active cooling: For this, the function of the heat pump is simply reversed. This cooling is also called "reversible" operation, i.e. the refrigerant circuit is reversed internally or cooling is activated through an external switchover of the primary and secondary connections. As with a fridge, cooling is then actively generated by the heat pump. NC-Box Optional equipment for Viessmann heat pumps to provide passive cooling. Page 46 AC-Box Optional equipment for Viessmann heat pumps to provide active cooling. Page 47

Natural cooling NC-Box Energy efficient and affordable cooling with the NC-Box The Viessmann NC-Box helps heat pumps to provide cooling in a completely natural way. In fact, it's really quite simple. On hot summer days, the temperatures inside your house are higher than in the ground or groundwater. The heat pump control unit then switches to natural cooling, and uses the ground or groundwater to dissipate the heat from your living space. Saving while cooling The natural cooling function does not use all the technology of the heat pump. This means that, apart from the control unit and circulation pumps, all other functions remain off. Only a very small amount of power is therefore consumed for operation, making natural cooling a particularly energy-efficient and affordable way to cool buildings. Everything you need to keep it cool In the Viessmann "Natural Cooling Box", all the components are prefitted. This makes the thermally insulated box not only compact, but also particularly simple and quick to install. With or without mixer Depending on the sort of cooling needed, the natural cooling box comes in two different versions, either with or without mixer. The integral mixer enables continuous operation without falling below the dew point. The effective thermal insulation of the NC-Box prevents the formation of condensate.

Active cooling AC-Box 46/47 Efficicnet heating or cooling with the AC-Box The Viessmann AC-Box combines active cooling and natural cooling in your heat pump systems, thus making it even more versatile and convenient. Depending on how cool you would like it to be in your rooms, the system switches over automatically. If only a low cooling output is required, then natural cooling is adequate, but if that is no longer sufficient, active cooling is added. Cooling using tiny amounts of energy With natural cooling, the compressor circuit is not needed. Only the brine and heating circuit pumps are operational and utilise the temperature differential between the rooms and the ground or groundwater. This means they cool the rooms in a particularly costeffective way. Keep cool when it gets really hot outside With active cooling, the compressor circuit starts to work. However, it does not provide heating the internal control unit, in conjunction with the AC-Box, reverses the output and input functions and now actively transfers heat out of the building to the geothermal probe. Cold water now flows through the heating circuit itself cooled down to 7 C if required. Utilising extracted energy Incidentally, you can also make direct use of the heat transferred out of the rooms in this way, for example for DHW heating or to heat a swimming pool. This means you can combine the cooling and heating functions extremely effectively. Well thought-out technology: the AC-Box simply starts the heat pump with the active cooling or natural cooling function, subject to the cooling required.

Domestic ventilation system Vitovent 300

48/49 VITOVENT 300 Air quality makes a real difference to the quality of life inside our homes. An essential component of this is plenty of fresh air. However, modern construction practices do not make this easy, as buildings are designed to be as airtight as possible, to prevent heat loss. This is where the Vitovent 300 ventilation system comes in, creating a pleasant, healthy atmosphere in your room, without wasting energy. Air is considered to be fresh when its CO 2 - concentration falls below 0.1 % vol. and it is free from odours. Opening the window to achieve this initially seems to be the best idea. However, window ventilation is a bit hit and miss. Either we ventilate too much and waste heating energy, or we ventilate too little and then feel tired and weary. In contrast, the Vitovent 300 domestic ventilation system continuously replaces the air and removes odours and noxious substances, giving you a continuously pleasant, healthy atmosphere. Prevent mould, protect the building fabric One of the main causes of mould growth is humid room air. Caution: Not only does mould look unsightly, it is also unhealthy, both for you and the structure of your home. However, investing in a domestic ventilation system is cheaper than remedying building damage caused by fungal growth and mould. Allergy sufferers can breathe a sigh of relief A filtration system, employing an effective pollen filter (cat. F6), cleans the fresh outside air of harmful substances. This allows allergy sufferers to enjoy fresh air too and reducing the growth of mites and mould fungus is beneficial for everyone. Enjoy security and quietness Vitovent 300 ensures a continuous air change so windows can stay closed all year round. That doesn't just offer improved safety against burglary, but also keeps out any noise there may be outside.

Domestic ventilation system Vitovent 300 Ventilating virtually without energy loss Saving energy is the trump card of the Vitovent 300. The powerful heat exchanger recovers more than 90 percent of the latent heat contained in the used air and uses it to heat the incoming air. Thanks to the very efficient DC motors, per 1 kwh of electrical energy used, 15 times more heating energy is recovered. This means that in a living area of 150 m 2 for example, you save approx. 300 l fuel oil a year. Cooling with night air In winter, the majority of the heat contained in the extract air is recovered through the heat exchange function. In summer, the heat exchanger is completely bypassed via the integral bypass damper. Through this temperature-controlled bypass circuit, cool outside air can enter the rooms during the night. Fastflex flat duct system is space-saving and easy to install The Fastflex system for air distribution is precisely matched to the Vitovent 300. For one thing, it makes it easier to install and set up the domestic ventilation system, and for another, it also saves space. On one routing level, two floors can be simultaneously accessible. The flat ducts are not only so versatile that they can adapt to suit any structural characteristics, but they are also particularly stable, and can be routed below the screed in the floor insulation. 2 1 3 1 4 Vitovent 300 domestic ventilation system with heat recovery 1 DC fans 2 Bypass damper 3 Heat exchanger 4 Air filter

System technology Domestic hot water The Vitocell range from Viessmann offers the right DHW cylinder for every demand. DHW convenience for every demand With the Vitocell DHW cylinders, Viessmann offers you the convenient solution to supplying your household with hot water the perfect extension to your new heat pump. The demand for hot water is completely different in every household. One factor is the number of residents and another is their bathing and showering habits. For example, several people in one household frequently go to work and school at the same time, so lots of hot water needs to be continuously available for the shower in a short space of time. Those who have a bath regularly may also wish to have enough warm water to fill the tub. Finally, the DHW cylinder should be able to deliver sufficient water, if in an apartment block, hot water is drawn from more than one outlet at the same time. The Vitocell DHW cylinders fulfil these requirements in every respect and are also robust enough to cope with constant demand.

58/59 Optimally matched for use with heat pumps Viessmann system solutions from a single source make it easy for you to utilise the energy from your heat pump to optimum effect, for example with a suitable DHW cylinder especially for heat pumps that are specifically designed for the requirements of detached and two-family homes when using a Vitocal 200, 300 or 350. DHW convenience that's as individual as you are The DHW cylinder is prepared for the connection of a solar thermal system or the installation of one or two additional electric booster heaters with up to 6 kw output for boosting the DHW temperature. Strong inner values Viessmann's product range includes the Vitocell 300 and Vitocell 100 product groups. All Vitocell 300 cylinders are made of stainless steel and meet the most stringent hygiene requirements. It is no coincidence that stainless steel is also used for its antibacterial properties in the processing industry, in kitchens and in hospitals. Squeaky clean: the Vitocell 300 DHW cylinders are made of stainless steel a material that meets the highest hygiene standards. Alternatively, the inner surfaces of the Vitocell 100 are lastingly protected against corrosion with the proven Ceraprotect enamel coating. All DHW cylinders are fully equipped with high-grade insulation against heat loss. Internal indirect coils drawn low down to the cylinder floor enable quick and energyefficient heating of the entire cylinder content.
