Heat pumpsVitocal 343-GVitocal 333-GCompact <strong>heat</strong> pumpsThe Vitocal 343-G <strong>and</strong> Vitocal 333-G areoffered as three versions, i.e. <strong>with</strong> <strong>and</strong> <strong>with</strong>outsolar thermal connection <strong>and</strong> <strong>with</strong> integralnatural cooling function. DHW cylinders <strong>with</strong>170 litre capacity (solar version <strong>with</strong> 220 litre)are integrated to safeguard high DHWconvenience. At the core of the appliance isa newly developed high efficiency <strong>heat</strong> pumpmodule.These compact appliances are particularlyeconomical thanks to the refrigerant circuit<strong>with</strong> electronic expansion valve (EEV) <strong>and</strong>the <strong>Viessmann</strong>-developed RCD (RefrigerantCycle Diagnostic) system, plus the st<strong>and</strong>ardenergy saving high efficiency pumps. Thisis reflected day by day <strong>and</strong> year by year inhigh seasonal performance factors <strong>and</strong> lowconsumption costs.Small footprintWith their space saving designs, theVitocal 343-G <strong>and</strong> Vitocal 333-G areparticularly suitable for situations wherespace is restricted. The brine circulationpump, <strong>heat</strong>ing circuit pump <strong>and</strong> the 3-waydiverter valve are already integrated insidethe compact casing that completelyprotects the refrigeration module/hydrauliccompartment from the outside environment<strong>and</strong>, in conjunction <strong>with</strong> the three-dimensionalanti-vibration mounts, minimises operatingnoise. These compact <strong>heat</strong> pumps are someof the quietest in their category, as they onlygenerate 38 dB(A) at brine 0 °C/water 35 °C.For easier h<strong>and</strong>ling, the height of the unitwas reduced <strong>and</strong> the casing was designedto split into sections. Variable connectionaccessories supplied ex works make <strong>heat</strong>pump installation easier.1Extremely easy to operateLike all our compact appliances, theVitocal 343-G <strong>and</strong> Vitocal 333-G, too, areequipped <strong>with</strong> the user friendly Vitotroniccontrol unit. If in doubt, help is available at thepush of a button. The graphic interface willalso display <strong>heat</strong>ing curves <strong>and</strong> solar yield.32Always accessibleSubject to dem<strong>and</strong>, the Vitotronic control unitcan be fitted <strong>with</strong> convenient communicationtechnology. From Vitocom 100 toVitocom 300, versatile remote monitoring<strong>and</strong> remote control options are available,independent of the system user's location.Vitocal 333-G1 DHW cylinder,170 litre capacity2 Vitotronic 200<strong>heat</strong> pump control unit3 Internal indirect coilcylinder <strong>heat</strong>ing4 Primary pump(high efficiency pump)5 Secondary pump475(high efficiency pump)6 Hermetically sealedCompliant scrollcompressor7 Diverter valve68<strong>heat</strong>ing/DHW8 Integral instantaneous<strong>heat</strong>ing water <strong>heat</strong>er
