15.5 Pressure drop
Taps
Pressure drop at taps at flow rate of 10 l/min
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
When calculating the size of the pipework, a pressure
drop for the appliance of 0.1 MPa is recommended.
15.6 Fault conditions
In case of faults, loads up to a maximum of 95 °C at a
pressure of 1.2 MPa can occur temporarily in the instal-
lation.
15.7 Details on energy consumption
Product data complies with EU regulations relating to the
Directive on the ecodesign of energy related products
(ErP).
