Product Information

Vitodens 222-F
The Vitodens 222-F storage combi-boiler combines
the benefits of the Vitodens 222-F with the high DHW
convenience of a separate DHW tank. With the
MatriX gas burner and the stainless steel Inox-Radial
heat exchanger, the Vitodens 222-F offers top technology
for many years of energy efficiency and high heating and
DHW convenience. The Lambda Pro Control combustion
controller and the 3-speed high efficiency circulation
pump, ensure permanently high efficiency, reliable
operation and low power consumption.
The Vitodens 222-F is equipped with integral sensor
technology that enables operation without minimum
flow rate. The integral stainless steel 26.5 USG (100 L)
primary storage tank offers the same DHW convenience
as a separate DHW cylinder approximately twice the size.
Recommended applications
■ Installation in single or semi-detached homes and
apartments.
■ New build (e.g. pre-fabricated houses and housing
association projects): installation in utility rooms
and attics.
■ Modernisation: Replacement of system boilers,
floorstanding atmospheric gas boilers and oil/gas
boilers with DHW cylinders below.
Delivered condition
Gas condensing boiler with Inox-Radial heat exchanger,
modulating MatriX gas burner for natural gas and LPG
cylinder, expansion vessel, 3-speed high efficiency
circulation pump and integral stainless steel DHW
primary storage tank. Fully piped plumbed and wired.
White epoxy-coated casing. Preset for operation with
natural gas. The conversion to LPG is made at the gas
valve (a conversion kit is not required) and control unit.

Innovative Storage Tank Loading System (STLS)
Advanced Storage Tank Loading System technology in
the Vitodens 222-F ensures a reliable and efficient DHW
supply equivalent to that of a larger tank. The STLS
utilizes an external plate heat exchanger and DHW loading
pump for extremely fast heat-up capable of delivering a
10 minute peak flow of 60 gallons or continuous DHW
draw of 3.3 GPM*.
