Heating with air and geothermal heat - Viessmann

Heat pumpsVitocal 300-GEHPA quality seal asproof of the COP, forsubsidy according tothe German marketincentive programmeThe Vitocal 300-G is a specialist appliancefor large detached houses and apartmentbuildings. It utilises heat that's right on yourdoorstep, either with a single stage brine/water heat pump, from 21.2 to 42.8 kW,or with a water/water heat pump from28.1 to 58.9 kW – tailored to the specificheat demand.For apartment buildings or applications whichrequire very high outputs, the two-stageVitocal 300-G, based on the master/slaveprinciple, is the right choice. It can deliver aheating output from 42.4 to 85.6 kW (brine/water) or from 56.2 to 117.8 kW (water/water). You also have the choice between thegroundwater or the ground as your preferredheat source. If this output is still insufficient,it can be increased to up to 589 kW (water/water) via the cascade function integrated intothe control unit.Powerful and reliableAt the heart of the Vitocal 300-G lies itspowerful Compliant scroll compressor. Thisconvinces with a high degree of operationalsafety and reliability. In conjunction withthe generously sized heat exchangers andthe integral refrigerant manifold, theVitocal 300-G achieves high coefficientsof performance and flow temperatures ofup to 60 °C.Quiet operation and high output are notmutually exclusiveThe hermetically sealed casing and particularlyclever appliance design enable a reduction innoise emissions in the Vitocal 300-G that farexceeds expectations in this output range.RCD system for highest level of efficiencyRCD stands for Refrigerant Cycle Diagnosticsystem. It provides permanent monitoring ofthe refrigerant circuit within the Vitocal 300‐Gand, in conjunction with the electronicexpansion valve, ensures the highest level ofefficiency at any operating point.Perfect even for high heat demandEspecially for a higher heat demand, theVitocal 300-G is the first choice, becauseseveral heat pumps can be linked via theheating flow and return. This does not justdeliver the higher heating output required, butit also increases the operational reliability ofthe entire 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.1234Vitocal 300-G51 Weather-compensated, digitalVitotronic 200 heat pump control unit2 Condenser3 Large area evaporator for efficientheat transfer4 Hermetically sealed Compliant scrollcompressor5 Electronic expansion valve
