TV = 80 °C, starting storage tank temp. TSP = 65 °C, cold water temp.TKW = 10 °C, hot water temp. TWW = 45 °C.(24) The spec. water flow acc. to EN 13203 is the domestic water flow at an average temperature increase of 30 K, which theGCU compact can supply if two draw-off procedures each of 10 minutes duration are performed one after the other, assum-ing a charging temp. of 65 °C. A delay of 20 minutes between the two draw-off procedures is usually assumed. TheGCU compact achieves this value with even shorter waiting periods.(25) Reheating with nominal output, starting storage tank temp. TSP = 60 °C, cold water temp. TKW = 10 °C, hot water temp.TWW = 40 °C.
