15.3 DHW output
The DHW output is subject to the mains voltage, the appliance's
connected load and the cold water inlet temperature. The rated
voltage and rated output can be found on the type plate (see chap-
ter "Troubleshooting").
Connected load in kW 38°C DHW output in l/min.

15.5 Pressure drop
Taps/valves
Tap pressure drop at a 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, an appliance pressure
drop of 0.1MPa is recommended.
15.6 Fault conditions
In the event of a fault, loads up to a maximum of 95 °C at a pressure
of 1.2MPa can occur temporarily in the installation.
15.7 Details on energy consumption
The product data complies with EU regulations relating to the Di-
rective on the ecological design of energy related products (ErP).
