17.3 Domestic hot water output
The DHW output is subject to the connected power supply, the
appliance's connected load and the cold water inlet temperature.
The rated voltage and rated output can be found on the type plate.

17.5 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
Shower head, 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.
17.6 Fault conditions
In the event of a fault, loads up to 80°C at a pressure of 1.0 MPa
can occur briefly in the installation.
