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
chapter “Operation / Troubleshooting”).
Connected load in kW 38 °C DHW output in l/min.

15.5 Pressure drop
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 installation.
