Smart, compact space heating and DHW
The Vitodens 222-F, B2TB gas-fired
condensing boiler is an ideal space saving
option for new installations and a smart
upgrade for outdated boiler and domestic
hot water (DHW) storage systems. The floor
standing Vitodens 222-F is available in two
input sizes, offering compact, economical
space heating and DHW solutions for homes
with moderate heating loads.
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 (model B2TB-35 only) or
continuous DHW draw of 3.3 GPM*.
Award winning control unit
The intuitive Viessmann made Vitotronic
200, HO1B control manages the entire
heating system and maintains economical
performance and maximum comfort at all
times. The user-friendly, menu-driven control
is capable of displaying multi-line text and
graphics on a backlit display 70% larger
than those of comparable units. The high
contrast, monochrome display offers excellent
readability, even under poor lighting conditions.
An outdoor reset function automatically
adapts the boiler operating temperature to the
changing outdoor temperature. This reduces
fuel consumption up to 15%, giving you
excellent returns year after year on a modest
initial investment. Plus, with system control
for multiple zone space and DHW heating,
the Vitotronic 200, HO1B offers even greater
heating flexibility without additional
external controls.

Proven Viessmann technology
At the heart of the Vitodens 222-F are the
Viessmann made SA240 316Ti stainless steel
Inox-Radial heat exchanger and low emission
MatriX cylinder burner.
The MatriX burner’s Lambda Pro combustion
management system automatically adapts
to changing gas type and quality for optimal
efficiency, while the durable stainless steel
heat exchanger offers exceptional reliability
and long service life. Together, they allow for
optimal heat extraction with minimal heat loss
to maximize energy utilization and reduce fuel
consumption.
Low Lead Certification
Certified to CSA Low Lead Certification
Program; including US Safe Water Drinking
Act, NSF/ANSI 372 as well as other applicable
US State requirements.
