A Tradition of Excellence
The World’s leader in heating
technologies since 1825, Buderus
produced the world’s first low-
temperature hydronic heating
systems. Today, Buderus products are
acknowledged as the world standard
in high-efficiency, low emissions
hydronic heating. All Buderus products
are designed to meet strict safety and
environmental regulations.
Buderus boilers are quick and easy to
install and will outlast and outperform
virtually any other commercial hot
water heating system. They are
designed for easy access and service.
With appropriate maintenance, Buderus
boilers deliver the highest possible
efficiencies throughout the lifespan
of operation.
In 2008 Buderus became a member
of the Bosch Group, representing
the Bosch, Buderus and FHP brands
with products that are designed to
improve efficiency, reliability and
are environmentally friendly. Bosch
Thermotechnology offers floor-standing
and wall hung boilers, water heaters,
