Vitodens 222-F, type B2SB

2.1 Product description

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.
As with all Viessmann storage combi boilers, the Vitodens 222-F gas
condensing boiler requires very little space: Width and depth corre-
spond to standard kitchen unit dimensions. The proven MatriX cylin-
der burner with Lambda Pro Control Plus combustion controller auto-
matically adjusts to varying gas qualities and ensures a constantly
high standard seasonal efficiency [to DIN] of 98 % (H
The Vitodens 222-F, type B2SB with integral 130 l cylinder with inter-
nal indirect coil is particularly suitable for hard water areas.
Due to its smooth surface the internal indirect coil is resistant to lime-
scale deposits.
