Reheating is not considered if the cold water temperature is 10 °C. The maximum medium flow rate is 25 l/
min, pressure loss of the fresh water station is 1000 mbar in this case (higher values are possible in a limited
way hydraulically. The maximum flow rate depends on the pressure loss on the primary side. The maximum
dispensing quantity depends on the length and insulation of the pipe.
*) maximum medium flow rate of the EFS 50 is 88 l/min (EFS 35 = 65 l/min). The pressure loss of the fresh
water station is 1000 mbar in this case (higher values are possible in a limited way hydraulically. Measure-
ment limit of the medium flow rate probe ~ 133 l/min)
