17.5 Pressure drop
Taps/valves
Tap pressure drop at a flow rate of 10 l/min
Mono lever mixer tap, approx. MPa 0.04 - 0.08
Thermostatic valve, approx. MPa 0.03 - 0.05
Shower head, approx. MPa 0.03 - 0.15
Sizing the pipework
When calculating the size of the pipework, an appliance pressure
drop of 0.1MPa is recommended.
17.6 Fault conditions
In the event of a fault, loads up to 80°C at a pressure of 1.0 MPa
can occur briefly in the installation.
17.7 Test symbols
See type plate on the appliance.
17.8 Energy consumption data
The product data complies with EU regulations relating to the
directive on the ecodesign of energy related products (ErP).
