Heat pumpsVitocal 242-GVitocal 222-GNatural <strong>heat</strong> for modern detached housesThe Vitocal 242-G <strong>and</strong> Vitocal 222-G compact<strong>heat</strong> pumps are specifically designed fordetached houses. With their extremelycompact dimensions of just over 0.4 squaremetres, they need only a small installationarea. With integral DHW cylinder, brine <strong>and</strong><strong>heat</strong>ing circuit pumps, plus a 3-way divertervalve, these compact appliances are quick<strong>and</strong> easy to install. They are offered in twodifferent versions. The Vitocal 242-G hasa solar function <strong>and</strong> a generously sizedDHW cylinder <strong>with</strong> 220 litre capacity. TheVitocal 222-G has a 170 litre cylinder. Both<strong>heat</strong> pumps offer high DHW convenience.Extremely easy to operateLike all compact appliances, the Vitocal 222‐Gis equipped <strong>with</strong> the new user friendlyVitotronic control unit. If in doubt, help isavailable at the push of a button. The graphicinterface will also display <strong>heat</strong>ing curves <strong>and</strong>switching times.Particularly quiet operationThe sound-optimised appliance design makesthese compact <strong>heat</strong> pumps particularly quietso that they can even be installed close to theliving space.Compact <strong>and</strong> ready to connectThe casing may be split for easier h<strong>and</strong>ling.The <strong>heat</strong> pump is supplied ready to connect.Variable connection accessories ensure aneasy installation on site.<strong>Heating</strong> naturally – naturally coolingas wellThe compact <strong>heat</strong> pumps can provide apleasant climate in a low energy house, evenin hot summers. The natural cooling functionbrings cool underground temperatures intothe home. For this, the <strong>Viessmann</strong> NC-Box isrequired as an accessory.Vitocal 242-G1243Vitocal 242-G including optionalutilisation of solar energyWith the Vitocal 242-G, the connections fora solar thermal system are already in place,<strong>with</strong> the required hydraulic connections <strong>and</strong>the control unit integrated. The powerfulcollectors <strong>and</strong> matching system componentsfrom <strong>Viessmann</strong> back up the <strong>heat</strong> pump –meaning in an average year, 50 to 60 percentof energy usually spent on DHW <strong>heat</strong>ing canbe saved.1 <strong>Heating</strong> lance2 Enamelled5DHW cylinder3 Vitotronic 200 <strong>heat</strong>pump control unit4 Integral solar indirect coil5 PWM-controlled68cylinder primary pump(pulse width modulation)6 Primary circulation pump77 Secondary circulationpump8 Diverter valve9<strong>heat</strong>ing/DHW9 Integral instantaneous<strong>heat</strong>ing water <strong>heat</strong>er
