15.5 Pressure drop
Taps/valves
Pressure drop at taps, at 10 l/min flow rate
Mono-lever mixer tap, approx. MPa 0.04 - 0.08
Thermostatic valve, approx. MPa 0.03 - 0.05
Hand shower, approx. MPa 0.03 - 0.15
Sizing the pipework
To calculate pipework sizing, apply a pressure drop of 0.1MPa to
the appliance.
15.6 Fault conditions
In the event of a fault, loads up to a maximum of 80°C, at a pres-
sure of 1.0MPa, can temporarily occur in the installation.
15.7 Details on energy consumption
Product data complies with EU regulations relating to the Directive
on the ecodesign of energy related products (ErP).
