2)
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 d
raw-off procedures is usually
assumed.
The ROTEX GCU compact reaches this value also with shorter waiting periods.
