DHW circulation line
Junkers cylinders must be equipped with their own DHW
circulation connection.
Seal this connection if no DHW circulation line is
connected.
DHW circulation is only permitted with reference to the
cool-down losses if a time- and/or temperature-
dependent DHW circulation pump is provided.
Install a suitable non-return valve.

Connect the cylinders diagonally on the
heating water and DHW sides (according
to the Tichelmann principle).
This balances out different pressure drop
values.
B
Only connect one cylinder temperature
sensor.
