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.

The table on the left side shows
the total water volume for each
temperature layer within the tank.
The indication Tapping amount
50°C refers to the compressor
cut-off temperature.
