Performance Characteristic Tables
The following tables refer to the heating up of the water without reheating and can not be com-
part with Tapping profile data tables.
How to read the following tables:

The example table refers to a supply water temperature of 10°C.
The water in the tank is heated from 10°C to 50°C at an ambient temperature of 7°C. The heat-
ing phase takes 3:23:47h.
(Without tapping)
In practice, the cycle described above is valid during commissioning. If system design in ac-
cordance with local conditions, then in the rarest cases so much water is tapped that the tank is
completely emptied and filled with fresh water.
