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

15.5 Pressure drop
Taps/valves
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
To calculate pipework sizing, apply a pressure drop of 0.1MPa to
the appliance.
