Heat pumpsVitocal 350-GThe innovative RCD system, which providescontinuous refrigerant cycle control, ensureshigh efficiency at any operating point.The use of an electronic expansion valve(EEV) <strong>and</strong> high efficiency pumps (<strong>with</strong> typeBWC), as well as the high COP of 4.6, alsocontribute to the low running costs. Finally,the integral energy statement for central<strong>heat</strong>ing <strong>and</strong> DHW provides the basis forproperty developers to apply for subsidies[in Germany] for their environmentallyresponsible investment.Vitotronic 200 control unit <strong>with</strong>communication capabilityFollowing a st<strong>and</strong>ardised operatingphilosophy, <strong>Viessmann</strong> now uses theconvenient Vitotronic 200 control unit inall its <strong>heat</strong> sources. The extensive functionsinclude user guidance <strong>with</strong> menu prompts,an integral diagnostic system, control of theinstantaneous <strong>heat</strong>ing water <strong>heat</strong>er, control ofan additional (existing) oil or gas boiler, <strong>and</strong> ofcourse, the natural or active cooling functions.Furthermore, the Vitotronic 200 is capableof communicating, <strong>and</strong> via the Vitocom 300module, it allows the <strong>heat</strong> pump system tobe set up, monitored <strong>and</strong> optimised overthe internet.In combination <strong>with</strong> solar technologyAn advanced <strong>heat</strong>ing system shouldinclude innovative solar technology. Forthis, <strong>Viessmann</strong> offers the Vitocal 350-G, aperfectly matched system for utilising freesolar energy for supplying DHW. On hot dayselectricity is then only required to run thecirculation pumps.123Vitocal 350-GType BWC 351.A451 Vitotronic 200 <strong>heat</strong> pump control unit2 Condenser3 Large area evaporator for efficient<strong>heat</strong> transfer4 Integral high efficiency pumps for brine<strong>and</strong> <strong>heat</strong>ing circuits, plus circulation pumpfor cylinder <strong>heat</strong>ing5 Hermetically sealed Compliant scrollcompressor
