6.4.2 Selecting the volume and desired temperature for the storage tank
People experience water as hot when its temperature is 40°C. Therefore, the DHW
consumption is always expressed as equivalent hot water volume at 40°C.
However, you can set the storage tank temperature at a higher temperature
(example: 53°C), which is then mixed with cold water (example: 15°C). The
resulting domestic hot water temperature depends on this setpoint as well as the
actual storage tank temperature.
Determining the DHW consumption
Answer the following questions and calculate the DHW consumption (equivalent
hot water volume at 40°C) using typical water volumes:
