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, as its width and depth
correspond to the dimensions of standard kitchen units. The proven
MatriX cylinder burner with Lambda Pro Control Plus combustion
controller automatically adjusts to varying gas qualities and ensures
a constantly high standard seasonal efficiency [to DIN] of 98 % (H
[gross cv].
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.
