The temperature sensor connection [TS]
located at the top of the low-loss header
ensures low return temperatures to the
Vitodens 200 boiler at all times, increasing
operational efficiency.
In addition, the low-loss header helps
eliminate air and debris [D] from the heating
system.
See figures on the right for an illustration of
the principle of operation.
The low-loss header is available in the
following sizes. Select the size based on the
maximum system flow rate of your
application.
