Design of the storage tank

You can use the following table to calculate the approximate required volume of the buffer tank.

Temperature in buffer tank [°C] HW temperature [°C]

set in controller

Reqd. Storage tank volume per

litre of HW [Litre]

50 45 1.5

45 0.9

50 1.2

55 1.6

45 0.7

50 0.9

55 1.0

50 0.7

55 0.8

Sample calculation for the design of the buffer tank:

Temperature of buffer tank: 60 °C, required dispensing medium flow rate at water valve: 20 l/min

DHW temperature set on the controller: 45 °C

How large must the Storage tank be if a 20-minute dispensing operation is to take place without reheating?

20 l/min x 20 min = 400 l

400 l x 0,9 = 360 l ð The heated part of the buffer tank must be 360 litres in size.

The hot water volume depends on the position of the installed S 08 probe (Smart Control hot water

probe). The higher this is installed on the buffer tank, the lower the hot water volume.
