— One-hand mixer and thermostatic fittings must be suitable for
hydraulically controlled instantaneous water heaters.
— Practical hints:
So that the switch-on quantities (see Table 3) of stage • and stage
• • are safely reached, the pressure loses of the instantaneous
water heater, fitting, hand-held shower, shower hose and the pipe
network must be taken into account upon installation.
Typical pressure loss values for a shower water quantity of approx.
10 l/min:
— one-hand mixer 0.04 - 0.08 MPa
— thermostatic fittings 0.03 - 0.05 MPa
— hand-held shower 0.03 - 0.15 MPa
