DHW Production Planning
With the B1KA for instantaneous DHW heating or the
B1HA DHW connections for DHW production via a
stand-alone DHW storage tank, the Vitodens 100-W
boilers 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 instantaneous DHW production with the B1KA and
DHW production via a stand-alone DHW storage tank with
the B1HA.
