1.1 Product description

1
The Vitodens 222-F gas condensing storage combi boiler is
designed specifically for heating system modernisation projects and
as a replacement for older gas boilers with cylinders installed below.
With an output of up to 35 kW, this heating centre is designed for
high DHW convenience.
The integral loading cylinder with 100 l capacity (up to 26 kW) or
130 l capacity (35 kW) offers the DHW convenience of a separate
DHW cylinder approximately twice the size.
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].
Recommended applications
■ Installation in detached and terraced houses
■ New build (e.g. prefabricated houses and developer projects):
Installation in utility rooms and attics
■ Modernisation: Replacement of gas system boilers, floorstanding
atmospheric gas boilers and oil/gas boilers with DHW cylinders
installed below.
