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 "Operation / Troubleshooting").

15.5 Pressure drop
Taps
Pressure drop at taps at flow rate of 10 l/min
Mono lever mixer tap, approx. MPa 0.04 - 0.08
Thermostatic valve, approx. MPa 0.03 - 0.05
Hand shower, approx. MPa 0.03 - 0.15
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 case of faults, loads up to a maximum of 95 °C at a
pressure of 1.2 MPa can occur temporarily in the instal-
lation.
15.7 Details on energy consumption
Product data complies with EU regulations relating to the
Directive on the eco-design of energy related products
(ErP).
