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

17.4.1 Sizing the pipework
When calculating the size of the pipework, an water heater pressure
drop of 14.5 psi (0.1 MPa) is recommended.
17.5 Fault
conditions
In the event of a fault, temperatures up to 176 °F (80 °C) at a pressure
of 145 psi (1.0 MPa) can occur briefly in the installation.
