17.5 Pressure drop
Sizing the pipework
When calculating the size of the pipework, a water heater pressure
drop of 14.5 psi (0.1MPa) is recommended.
17.6 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.
