16.3 DHW output
The DHW output is subject to the connected power supply, the
water heater's selected power output, and the cold water inlet
temperature. The rated voltage and rated output can be found on
the type plate. See section 10.2, “Temperature setting via jumper
slot - operating voltage 240 V”, pg. 11 for further information.

Pressure drop, sizing the pipework
When calculating the size of the pipework, an water heater pres-
sure drop of 14.5 psi (0.1MPa) is recommended.
16.5 Fault conditions
In the event of a fault, temperatures up to 176 °F (80 °C) at a pres-
sure of 145 psi (1.0 MPa) can occur briefly in the installation.
