DHW Production Planning
With the CombiPLUS for instantaneous DHW heating
or with DHW connections for DHW production via a
stand-alone DHW storage tank, the Vitodens 100 boiler
series offers the right solution for every need.
Various factors must be taken into account when
designing the DHW system, and when deciding between
the DHW production with integrated CombiPLUS and the
standard heating boiler with DHW production via a stand-
alone DHW storage tank.
