Heating with air and geothermal heat - Viessmann

Heat pumps Vitocal 242-SVitocal 222-SCompact internal unitsWith their timeless design and a width of just60 cm, these internal units can be sited closeto the living space (e.g. in the utility room).They contain hydraulic components such asa heat exchanger (condenser), DHW cylinder,heating circuit pump, instantaneous heatingwater heater, 3-way diverter valve, andVitotronic 200 control unit.Heat pump control unit with user promptsThe Vitotronic 200 is structured logically,and its displays are easy to follow. The largebacklit display offers good contrast, making iteasy to read. The graphic user interface alsodisplays heating and cooling curves.If a solar thermal system is connected to theVitocal 242-S, the solar yield is shown as well.Efficient and economicalThe split heat pumps operate extremelyeconomically in partial load operation.Inverter technology accurately matchesthe compressor output to the current heatdemand through modulating operation.This results in high efficiency at anyoperating point.Extensive service from ViessmannThe external and internal units are connectedto the refrigerant lines on site to form asealed refrigerant circuit. Consequently, thelegislature specifies that the installation mustbe carried out by qualified personnel only.Heating contractors can acquire the relevantexpertise in accordance with the ChemicalSafety Ordinance [Germany] as part of aone-week course at Viessmann. The systemcan also be commissioned by Viessmann'sTechnical Service department.Prepared for subsidiesWith the installation of an optional heat meter,the purchase of Vitocal 242-S/222-S heatpumps can be subsidised with public grants[in Germany].Vitocal 242-SInternal unit (left)1 Heating lance2 EnamelledDHW cylinder3 Vitotronic 200 heatpump control unit4 Integral solar indirect coil5 Diverter valveheating/DHW6 High efficiency pump7 Condenser8 Integral instantaneousheating water heater1243561Vitocal 200-SExternal unit (right)72 31 Evaporator2 Fan3 Compressor
