15.3 DHW output
The DHW output is subject to the mains voltage, the ap-
pliance's connected load and the cold water inlet temper-
ature. The rated voltage and rated output can be found on
the type plate (see chapter "Troubleshooting").

15.5 Pressure drop
Taps/valves
Pressure drop at taps at flow rate of 10 l/min
Mono lever mixer tap, approx.
Thermostatic valve, approx.
Hand shower, approx.
Sizing the pipework
When calculating the size of the pipework, a pressure
drop for the appliance of 0.1 MPa is recommended.
15.6 Fault conditions
In the event of faults, loads up to a maximum of 95 °C
at a pressure of 1.2 MPa can temporarily occur in the
installation.
