• Prestatie systeem 1 >>systeem systeem 2 (nota Asc) • gezinsgrootte Sysprestatie (minder uitgesproken voor sys 2) • Goed gedimensioneerde SHPmindere prestatie voor andere SWW-profielen (bvb. owv gezinsgrootte) • Beste p prestatie @ Tinstel,SWWtank p ) instel SWWtank=45°C ((T44 SWW-profiel) • Penalty factor 1.5 kan beslissend zijn in nadeel van SHP met BU-heater in vergelijking met prestatie andere systemen
