1.1 Product description
A
Inox-Radial heat exchanger made from stainless steel – for high
operational reliability, a long service life and high heating output
on a very small footprint
B
Modulating MatriX cylinder burner with intelligent Lambda Pro
Control Plus combustion controller for clean combustion and
quiet operation
C
Integral diaphragm expansion vessel
D
Digital boiler control unit
E
Integral variable speed high efficiency circulation pump
F
DHW loading cylinder
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 % (Hs)
[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.
Benefits at a glance
■ Standard seasonal efficiency [to DIN]: Up to 98 % (Hs) [gross cv]
■ Durable and efficient thanks to the Inox-Radial heat exchanger
■ Modulating MatriX cylinder burner with a long service life thanks to
stainless steel MatriX gauze
– Tolerant to high temperature loads
– Modulation range down to 01:19 (35 kW)
■ High DHW convenience through enamelled loading cylinder with
100 l capacity (35 kW: 130 l capacity)
■ Power saving, high efficiency circulation pump
■ New, innovative operating concept using colour touchscreen with
plain text and graphic display, commissioning assistant and displays for energy consumption, as well as alternative operation
from a mobile end device
■ Web-enabled through Vitoconnect (accessories) for operation and
service via Viessmann apps

Variable speed heating circuit pump in the Vitodens 222-F
The integral circulation pump is a highly efficient pump with substantially lower power consumption than conventional pumps.
The pump speed and consequently the pump rate are regulated subject to the outside temperature and the switching times for heating or
reduced mode. The control unit transmits the current default settings
to the circulation pump via an internal data bus.
The min. and max. speed and the speed in reduced mode can be
adjusted using codes at the control unit of the existing heating system.
In the delivered condition, the minimum pump rate (coding address
"E7") and the maximum pump rate (coding address "E6") are set to
the following values:

condition in %

26 45 80
35 45 90
Note
In conjunction with a low loss header, heating water buffer cylinder
and heating circuits with mixer, the internal circulation pump runs at
a constant speed. The speed can be adjusted subject to demand by
changing the code at the control unit.

Variable speed heating circuit pump in the Vitodens 222-F
The integral circulation pump is a highly efficient pump with substantially lower power consumption than conventional pumps.
The pump speed and consequently the pump rate are regulated subject to the outside temperature and the switching times for heating or
reduced mode. The control unit transmits the current default settings
to the circulation pump via an internal data bus.
The min. and max. speed and the speed in reduced mode can be
adjusted using codes at the control unit of the existing heating system.
In the delivered condition, the minimum pump rate (coding address
"E7") and the maximum pump rate (coding address "E6") are set to
the following values:

Specification assembly kit with mixer
Assembly for heat distribution via one heating circuit with mixer and
one heating circuit without mixer, designed to match the appliance.
For installation on the boiler.
Comprising:
■ Plate heat exchanger for system separation of the heating circuit
with mixer
■ Variable speed high efficiency circulation pump for the heating circuit with mixer
■ 3-way mixer with mixer motor
■ Mixer PCB, capable of communicating with Vitotronic 200 via KMBUS
■ Adjustable bypass
■ Connection set for installation on finished or unfinished walls, with:
– Connection pipes
– Shut-off valves for heating water flow and return, with boiler
drain & fill valve
– 2 connectors for DHW
– Gas shut-off valve with thermally activated safety shut-off valve

Calculating the transferable heating output (examples)
The maximum heating output that can be transferred via the plate
heat exchanger of the assembly kit is 14 kW. For balanced flow rates
between the regulated heating circuit (assembly kit) and the unregulated heating circuit (radiator heating circuit), the pressure drop in
the assembly kit must be increased.
For this, the line regulating valve with flow indicator available as an
accessory can be fitted to the primary side of the plate heat
exchanger, i.e. between the flow and return. The nominal circulation
water volume of the boiler (see specification), minus the flow rate
through the plate heat exchanger of the assembly kit, results in the
flow rate of the unregulated heating circuit.
Example:
Vitodens 222-F, 26 kW
■ Nominal amount of circulation water at ΔT 20 K: 1018 l/h
■ Heating output for regulated heating circuit (assumed): 13 kW
■ Resulting flow rate, primary side, plate heat exchanger at ΔT 20 K:
560 l/h ≙ 9.3 l/min (to be set via the line regulating valve)
■ Flow rate of the unregulated heating circuit: 1018 l/h – 560 l/h =
458 l/h
