Introduction

6/7Saving energy and protecting the climateViessmann is aware of its responsibility for sustained protection of the environment.Our company philosophy and products have been constructed with this duty in mind."Nothing is so good that it cannot beimproved". This maxim is also reflected inour company principles. In this industry,Viessmann can rightfully claim to be theleader in quality and technology, and as such,aims to continually set new standards.Of course, this applies in particular tothe company's product range, which isconsistently geared towards significantlylowering the consumption of fossil fuels,and gradually replacing them with renewablesources of energy.At around 40 percent, the heating marketactually accounts for the largest proportionof energy consumption in Germany. The restis shared by "goods transport", "personaltransport" and "power", with 20 percent each.These are values that can also be appliedapproximately to other industrial countries.Ever-rising energy costs mean that theemphasis is on reducing the consumption offossil fuels as quickly as possible and utilisingthese fuels with greater efficiency.Heat from natureHeating from ViessmannHeat pumps should be your first choice if yourpriorities are both to save on heating costsand to generate heat in an environmentallyresponsible way. After all, the environmentgives us an unlimited and free supply of theenergy a heat pump uses. This fully‐fledgedheating system only consumes littlepower for drives and pumps to make thatenergy available. A heat pump makes youindependent of fossil fuels, and in additionmakes an active contribution towardsreducing CO 2emissions and protectingthe climate.As a pioneer in the field of standard heatpumps, Viessmann has been settingstandards in efficient utilisation of energy andlongevity of service life with its advancedsystems for 30 years. This means thesystem user also benefits from Viessmann'smany years of experience as a supplier ofcomprehensive heating systems.Whether for modernisation or new build:Viessmann always has the right solution!Viessmann offers energy efficientheating systems for oil, gas, solar,biomass, air and geothermal heat.The pictograms are designed toaid orientation when selectinga system.

IntroductionSimple principle, great resultA heat pump works in a similar way to a fridge – simply the other way round.VITOCAL 300In a fridge, heat is transferred from theinside to the outside. With a heat pump,this happens exactly the other way round.Heat from the air or the ground is transferredinto the living space via the heating system.Vapour from a refrigerant is compressed toincrease the temperature, to make it highenough for central heating and DHW heating.In this process, the Vitocal 350-G reachesup to 72 °C; the Vitocal 350-A up to 65 °C.These heat pumps can therefore also beused for modernisation as they can provide asufficiently high flow temperature for centralheating with radiators.Highly efficient scroll compressorThe compression process is vital for theefficiency of a heat pump. For this, Viessmannuses a Compliant scroll compressor. Itis characterised by quiet operation, lowvibrations, low maintenance and an extremelylong service life.To generate heat, for example, heat isextracted from the ambient air and used toevaporate a refrigerant that boils at lowHeat pumptemperature. The gas created is compressedby the scroll compressor, which causes it toheat up. The gas heated in this way transfersits heat via the condenser to the heatingwater or DHW heating system, and therebycondenses again. Finally, the refrigerant,which is still under pressure, is expandedin an expansion valve, and the circuitbegins again.A heat pump can make use of thefollowing energy sources:• Air – practically unlimited availability;lowest investment costs• Ground – via geothermal collector orgeothermal probe; very efficient• Water – extremely efficient; observewater quality• Waste heat – subject to availability, volumeand temperature level of the waste heatThe best heat source for each individual casedepends on local conditions and the actualheat demand.Seasonal performance factorThe coefficient of performance (COP) isthe ratio of the heat transfer to the powerconsumption. The seasonal performancefactor is the average of all COPs occurringin a year.Compression processThe coefficient of performance is used tocompare heat pumps with regard to efficiency,yet only applies from a particular operatingpoint under defined temperature conditions.55 °CGroundtemperature all year round between 5 and 18 °C (at 2 m depth)Getting hotter towards the centre – from an initialtemperature of between 5 and 18 °C, a flow temperatureof up to 72 °C is achieved.For planning (for example, to be able tospecify the consumption costs arising fromusing a heat pump), it is necessary to considerthe heat pump operation over the wholeyear. For this, the heat volume transferredover the year is given in relation to the overallelectrical power drawn by the heat pumpsystem over the same period. This includesthe amounts of power used by pumps, controlunits, etc. The result is given as the seasonalperformance factor.

As part ofthis development, generously sized heatexchangers have been integrated to enable ahigh COP (COP = coefficient of performance)of 4.7 to be achieved, in accordance withEN 14511, with brine 0 °C/water 35 °C.The seasonal performance factor specifiesthe relationship between the heat volume(heating energy) transferred and the energy(drive energy) supplied, over the course of ayear. The innovative RCD (Refrigerant CycleDiagnostic) system played a vital role in theimprovement of the seasonal performancefactor. This system enables a highly preciseand rapid control of the refrigerant circuitvia an electronic expansion valve. TheRCD system ensures that the heat pumpoperates with optimum efficiency at everyoperating point.With solar cylinder or natural coolingVitocal 343-G is designed for the connectionof a solar thermal system for DHW heating. Agenerously sized solar cylinder with 220 litrecapacity and a solar control unit have beenintegrated into the appliance for this purpose.In the compact Vitocal 333-G, a DHW cylinderwith 170 litre capacity ensures a convenientsupply of DHW. To help cool you down onhot summer days, the Vitocal 333-G is alsoavailable in a version with an integral naturalcooling function.EHPA quality seal as proof ofthe COP, for subsidy accordingto the German marketincentive programmeIn addition, energy saving, high efficiencypumps for the brine and heating circuitsensure very low consumption costs andtherefore a high seasonal performance factorin all three output sizes.

Heat pumpsVitocal 343-GVitocal 333-GCompact heat pumpsThe Vitocal 343-G and Vitocal 333-G areoffered as three versions, i.e. with and withoutsolar thermal connection and with integralnatural cooling function. DHW cylinders with170 litre capacity (solar version with 220 litre)are integrated to safeguard high DHWconvenience. At the core of the appliance isa newly developed high efficiency heat pumpmodule.These compact appliances are particularlyeconomical thanks to the refrigerant circuitwith electronic expansion valve (EEV) andthe Viessmann-developed RCD (RefrigerantCycle Diagnostic) system, plus the standardenergy saving high efficiency pumps. Thisis reflected day by day and year by year inhigh seasonal performance factors and lowconsumption costs.Small footprintWith their space saving designs, theVitocal 343-G and Vitocal 333-G areparticularly suitable for situations wherespace is restricted. The brine circulationpump, heating circuit pump and the 3-waydiverter valve are already integrated insidethe compact casing that completelyprotects the refrigeration module/hydrauliccompartment from the outside environmentand, in conjunction with the three-dimensionalanti-vibration mounts, minimises operatingnoise. These compact heat pumps are someof the quietest in their category, as they onlygenerate 38 dB(A) at brine 0 °C/water 35 °C.For easier handling, the height of the unitwas reduced and the casing was designedto split into sections. Variable connectionaccessories supplied ex works make heatpump installation easier.1Extremely easy to operateLike all our compact appliances, theVitocal 343-G and Vitocal 333-G, too, areequipped with the user friendly Vitotroniccontrol unit.

Heat pumps Vitocal 300-G

24/25VITOCAL 300-GThe Vitocal 300-G heat pump utilises the renewable heat stored underground or ingroundwater. A two-stage version is available for high heating outputs.As a single stage brine/water heat pump,the Vitocal 300-G obtains heat from theground. This does not necessitate drillinga geothermal probe or laying geothermalcollectors on the property. In both cases, theheat pump covers the entire energy demand,even on colder days.As an alternative, depending on the locationof the house, it may also be possible to utilisethe heat contained in groundwater. In thiscase, the Vitocal 300-G is simply configuredfor operation as a water/water heat pump. Itcan be used for new build and modernisationin detached houses and apartment buildings.The Vitocal 300-G iscertified in accordancewith the EHPA qualityseal for Heat Pumps.

Heat pumpsVitocal 300-GHigh output and quiet operationThe powerful Compliant scroll compressorfitted in the Vitocal 300-G heat pump isoutstanding on account of its high operationalsafety, reliability and especially quietoperation. Essentially, this is due to the twinsound insulation that includes anti-vibrationmounts to prevent structure-borne noise andinsulates the casing against air-borne noise.At the same time, the compressor guaranteesthe highest coefficients of performance (COPup to 4.9) and flow temperatures up to 60 °C.The Refrigerant Cycle Diagnostic (RCD)system constantly monitors the refrigerantcircuit in the Vitocal 300-G and, in conjunctionwith the electronic expansion valve, ensuresthe highest efficiency at any operatingpoint, which results in high seasonalperformance factors.Vitotronic 200, with energystatement facilityThe Vitotronic 200 is simple and intuitive tooperate, thanks to the plain text user promptsand graphic display. Amongst other features,it enables an integral differentiated energystatement, which is accepted by subsidybodies [in Germany].Modular solution for higher heat demandFor residential buildings with a higher heatdemand, the two-stage Vitocal 300-G,based on the master/slave principle is theright choice. It can also be configured forthe ground or groundwater as the heatsource. For this purpose, two heat pumpsare linked together. This does not just deliverthe high heating output required, but it alsoincreases the operational reliability of theentire system. The modular design, withseparate compressor circuits, also ensuresparticularly high levels of efficiency in partialload operation, and enables the simultaneousoperation of central and DHW heating.With five output stages as a master ormaster/slave version, various combinationscan be realised and matched to the requiredheat demand. Because of this flexibility,systems can be configured so that runtimesmatch demand, thus saving you money. Themaster module regulates the slave module.Furthermore, the entire system can beequipped with high efficiency pumps.1234Vitocal 300-G51 Vitotronic 200 heat pump control unit2 Condenser3 Large area evaporator for efficientheat transfer4 High efficiency pump5 Hermetically sealed Compliant scrollcompressor

Heat pumps40/41Cooling with heat pumpsAlongside pleasant heating convenience and reliable DHW heating, heat pumps alsoprovide cooling for a building.No-one would turn on the central heating ona hot summer day. With a Viessmann heatpump, the situation is different, as sometypes offer an additional cooling function.Active or passive coolingCooling operates according to two differentmethods:• Passive cooling: This is where the brinemedium or the groundwater absorbsthe energy from the heating circuit via aheat exchanger and transfers it outside.This function is also called natural cooling,as it uses the natural ambient temperature.Apart from the control unit andcirculation pump, the heat pump remainsswitched off.Natural cooling – naturallyWhile the ground or groundwater is usedin winter to provide energy for heating, insummer it can be used for natural cooling.With the natural cooling function, the controlunit only starts the primary pump and heatingcircuit pump. This means the relatively hotwater from the underfloor heating systemcan transfer its heat via the heat exchanger tothe brine in the primary circuit. This extractsheat from all rooms that are connected, whichmakes natural cooling a particularly energyefficient and affordable way to cool buildings.• Active cooling: For this, the function of theheat pump is simply reversed. This methodof cooling can be described as "reverseoperation". This means that the refrigerantcircuit is reversed internally or reversal isachieved by an external changeover of theprimary and secondary circuits. As with afridge, cooling is then actively generated bythe heat pump.NC-BoxOptional equipment forViessmann heat pumps toprovide passive coolingPage 42AC-BoxOptional equipment forViessmann heat pumps toprovide active coolingPage 43

Natural coolingNC-BoxEnergy efficient and affordable coolingwith the NC-BoxThe Viessmann NC-Box helps heat pumpsto provide cooling in a completely naturalway. In fact, it’s really quite simple. On hotsummer days, the temperatures inside thehouse are higher than those in the groundor groundwater. The heat pump control unitthen switches to natural cooling, and uses theground or groundwater to dissipate the heatfrom your living space.Saving while coolingThe natural cooling function does not use allthe technology of the brine/water heat pump.This means that, apart from the control unitand circulation pumps, all other functionsremain off. Only a very small amount ofpower is therefore consumed for operation.This makes natural cooling a particularlyenergy efficient and affordable method forcooling buildings.Everything you need to keep coolIn the Viessmann "Natural Cooling Box", allcomponents are prefitted. This makes thethermally insulated box not only compact, butalso particularly simple and quick to install.With or without mixerDepending on the sort of cooling needed, thenatural cooling box comes in two differentversions, either with or without mixer. Theintegral mixer enables continuous operationwithout falling below the dew point.The effective thermal insulation of the NC-Box prevents theformation of condensate.

Active coolingAC-Box42/43The AC-Box efficiently combinesheating and coolingThe Viessmann AC-Box combines activeand natural cooling in heat pump systems,thus making them even more versatileand convenient. The system changes overautomatically according to the required roomtemperature. If only a low cooling capacityis required, natural cooling is sufficient, butif that is no longer enough active coolingis added.Cooling using tiny amounts of energyWith natural cooling, the compressor circuitis not needed. Only the brine and heatingcircuit pumps are operational and utilise thetemperature differential between the roomsand the ground or groundwater. In this way,rooms can be cooled very cost effectively.Keep cool when it gets really hot outsideWith active cooling, the compressorcircuit starts to work. However, it does notprovide heating – the internal control unit, inconjunction with the AC-Box, reverses theoutput and input functions to actively transferheat out of the building to the geothermalprobe. Cold water then flows through theheating circuit itself – cooled down to 7 °Cif required.Utilising extracted energyIncidentally, direct use can also be madeof the heat transferred out of the rooms inthis way, for example for DHW heating or toheat a swimming pool. This means coolingand heating functions can be combinedextremely effectively.Well developed technology:The AC-Box (to the left of the heatpump) simply starts the relevantheat pump function – eitheractive or natural cooling, dependingon the required cooling capacity.

64/65VITOVENT 300-FVITOVENT 300The Vitovent 300-F and Vitovent 300 domestic ventilation systems create a pleasant,healthy atmosphere in your room, without wasting energy.Air quality makes a real difference to thequality of life inside the home. For thishowever, an adequate air change rate isessential. However, modern constructionpractices do not make this easy, as buildingsare designed to be as airtight as possible, toprevent heat loss. The Vitovent 300 ventilationsystem offers the solution, enabling apleasant, healthy climate in the room.Air is considered to be fresh when its CO 2concentration falls below 0.1 percent byvolume and it is free from odours. Peopleusually open the windows to allow fresh air in.However, window ventilation is not particularlyreliable. If windows are left open for toolong, heat is wasted; not long enough, andtiredness results. In contrast, the Vitovent 300domestic ventilation system continuouslyreplaces the air and removes odours andnoxious substances. The result is a pleasant,healthy climate.Prevent mould, protect the building fabricOne of the main causes of mould growth ishumid indoor air. Mould can be unhealthyfor the occupants and will cause permanentdamage to the fabric of the building. From thispoint of view alone, investing in a domesticventilation system is cheaper than remedyingbuilding damage caused by fungal growthand mould.Allergy sufferers can breathe asigh of reliefThe Vitovent domestic ventilation systemsallow allergy sufferers to enjoy fresh air too.A filtration system, employing an effectivepollen filter, cleans the supply air of allergensand harmful substances. This reduces thegrowth and spread of mites and mouldfungus, creating an irritant-free environmenteven for allergy sufferers.Flat duct system for quick assemblyFor the Vitovent 300-F and Vitovent 300,alongside the already familiar accessories,the new, flexible, plastic flat duct systemcan be used, which is quick and easy toinstall. Its low height enables an integrationof this duct into ceiling/floor structures andcan be subjected to mechanical loads. Theconventionally applied sealing with cold shrinktape is not required. The smooth anti-bacterialsurface coating ensures permanently hygienicair handling. A silencer is already integrated inthe distribution box.Air distribution boxFlat duct systemSupply airsectionPlastic flat duct system for a rapid andstraightforward installationExtract airsection
