The combination tank consists
of a 100 l buffer tank and a 300 l
domestic hot water cylinder
which are hydraulically thermally
independent of each other.
Domestic hot water is prepared
using an integrated tube heat
exchanger with 3.2 m
2
heat ex-
changer area.

With the combo tanks PWD 750,
900 and 1250, the domestic hot
water preparation takes place
via integrated finned tube heat
exchangers, which heat up the
domestic hot water according to
the flow principle.
Integrated heat riser pipes use
the heating buffer as preheating
stage for domestic hot water
preparation.
A circular plate prevents the dif-
ferent water layers with varying
temperatures from becoming
mixed together.
Technical information on the
combo tanks can be found in the
technical appendix.
