The Vitodens 222-F storage combi boiler combines the benefits of
the Vitodens 200-W with the high level of DHW convenience of a
separate DHW cylinder.
Fitted with the MatriX-Plus gas burner and stainless steel Inox-
Radial heat exchanger, the Vitodens 222-F offers top technology for
energy efficiency and a high level of heating and DHW convenience
over the long term. The Lambda Pro Plus combustion controller and
the variable speed high efficiency circulation pump ensure perma-
nently high efficiency, reliable operation and low power consumption.
The integral DHW loading cylinder with 100 l capacity offers the
same DHW convenience as a separate DHW cylinder approximately
twice the size.
