The specif. water flow acc. to EN 15502 is the domestic water flow at an average temperature increase of 30 K, which the ROTEX GCU compact can supply if two
draw-off procedures each of 10 minutes duration are performed one after the other, assuming a charging temp. of 65 °C. A delay of 20 minutes between the two
draw-off procedures is usually assumed. The ROTEX GCU compact achieves this value with even shorter waiting periods.
