The specific water flow according to EN 625 is the potable water flow with a mean temperature increase of 30 K, which the ROTEX GCU
compact is able to deliver in two consecutive tappings of 10 min duration each with a charging temperature of 65°C. A delay of 20 minutes
between the two draw-off procedures is usually assumed. The ROTEX GCU compact reaches this value also with shorter waiting periods.
