IMPORTANT
Vitodens 200-W boilers can be used in conjunction
with the stand-alone DHW storage tanks offered by
Viessmann.
All Viessmann DHW storage tanks sold in North America
are available in “Vitosilver” finish only.
Size and select the DHW storage tank based on the
forecasted DHW consumption of the building in question.
For further technical information on DHW storage tanks,

For the connection of a stand-alone DHW tank, installation
fittings (field supplied), an external circulating pump for
DHW production (field supplied) and a DHW temperature
sensor (optional equipment, see Viessmann Price List for
order information) are required.
