Product Information
Vitogas 050
Impressive performance, yet a very compact
design. Due to its compact dimensions, the
Vitogas 050 is ideal for installation in small
mechanical rooms and even in closets. In
addition to saving space, the Vitogas 050 is
economical in two ways - initial investment
and operational cost.
The benefits at a glance:
H Economical, compact,withintegrated
power vent for side wall venting only.
H High operational relia bility and a long
service life due to special high-grade gray
cast iron with lamellar graphite and
uniform heat transfer to avoid stress
fractures.
H Large diameter, stainless steel burners
provide quiet, reliable performance;
Annual Fuel Utilization Efficiency
(A.F.U.E.) of up to 83.1%.
H Optimal operation due to wide water
passageways and a wet-base, sectional
design.
H Compact dimensions – therefore suitable
for installation in almost any mechanical
room, or even closet installation.
H Problem-free transport into
difficult-to-access boiler rooms due to light
weight and compact design.
Heat exchanger surfaces of special
high-grade gray cast iron for high
operational reliability and a long
service life
