... with the following flow conditions:
The flow rate of the heating circuit is greater than the
maximum possible water flow rate of the Vitodens
200-W B2HE boiler (see pages 37 and 38 for maximum
water flow rate of boiler).
The use of a low-loss header is strongly recommended if
the maximum water flow rate in the application
concerned exceeds the values shown on pages 37 and
38, or if the system flow rates are unknown.
The low-loss header is available as accessory part.
