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 “Troubleshooting”).

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 pres-
sure of 1.2 MPa can occur temporarily in the installation.
