7 DHW heating
7 DHW heating
DHW can be heated up in two ways:
–
With a DHW tank > 23
(the energy source of the DHW tank is the heat
pump or a buffer tank
[1]
)
–
With a fresh water module > 24
(The energy source of the fresh water module is a
buffer tank
[1]
)

DHW area in the buffer tank
Warm water rises and collects in the upper-
most area of​the buffer tank (= thermal stra-
tification). The DHW tank or the fresh water
module draws the required energy for DHW
heating from this uppermost area. Therefore,
this (held at an adjustable temperature level)
area in the buffer tank is also referred to as the
DHW area .

Temperatures and hystereses
1
Required temperature / hysteresis
The DHW tank (or the domestic hot water area in the
buffer tank) is charged when required until the set
Required temperature 1 is reached. A new charge
starts when the DHW tank temperature falls to the
value
Required temperature 1 less Hysteresis .
Example
- Required temperature 1 = 55°C
- Hysteresis = 10°C
The DHW tank charge starts when the DHW tem-
perature falls to 45°C (requirement: The temperature
of the energy source is 5°C above 45°C).
One-time charge
2
Is used to perform one-off re-heating of the DHW tank
(e.g. if no release times are defined or the operating
mode
Always Off is set). By pressing the button, the
DHW tank is recharged as soon as a charging
request is made by the DHW tank.
