The Buderus G115WS boiler is based on the highly successful G115, the World’s best selling
boiler. The G115WS has been redesigned and reengineered to extract and deliver more heat
from every fuel dollar, and now has higher outputs at less cost per BTU. Acknowledged as the
leader in high-efficiency, low emission hydronic heating, Buderus offers innovative design and
quality manufacturing with exceptional efficiency and performance.
A G115WS cast iron oil boiler is ideal for new installations or as a replacement for virtually
any make or model of boiler. They are compatible with most hot water tanks. Constructed with
superior materials and designed by the industry’s leading engineers, the G115WS boiler is raising
the standard for the industry. With two ETL approved venting options either into a chimney or
directly through the wall, the G115WS allows a wide range of installation possibilities.
A better way to heat your home.
Comfortable Efficient
Energy star ratings for boilers are based on
an Annual Fuel Utilization Efficiency (AFUE)
rating, which is a ratio of the heat produced
to the energy consumed on an annual basis.
Not only is the Buderus G115WS boiler
Energy Star rated, but it is also designed
for ease of installation and maintenance.
With features like a compact dimension and
integrated handles for ease of transporting,
adjustable leveling legs, rear tappings and
flue connection, baffles and clips for adjusting
stack temperatures and a heavy gauge blue
enameled jacket, a Buderus boiler is not only
efficient, but it is easy to install.
With a full swing burner door, which can be
hinged on either the left or the right, and
front access plugs which permit flushing of
the boiler’s interior, the G115WS can be
thoroughly and properly cleaned in a fraction of
the time it takes to clean a conventional boiler.
Keeping your home comfortable and warm is
a high priority—but it doesn’t have to come at
a high cost. Whether you heat by baseboard,
panel radiators, hydro-air systems or radiant
flooring, our advanced heating systems will
provide many years of exceptional comfort
and economy. Unlike a conventional boiler
which heats and circulates water at only
one temperature — typically 170° to 180° F
and keeps heating and circulating this high
temperature water until the thermostat signals
it to stop. A Buderus boiler, especially when
paired with the Logamatic control, eliminates
these room temperature swings by adjusting
the boiler water temperature to the current
conditions, saving fuel while keeping you warm
and comfortable.
Manufactured with the patented Buderus
GL-180M flexible cast iron, the sections
are tightly joined together and sealed
by profiled, beveled steel push nipples,
ensuring a long life with no leakage.
Special compounds provide a gas-tight seal for
safe and efficient operation. And, thanks to the
GL-180M cast iron’s amazing flexibility, this boiler
resists thermal shock under conditions of rapid
temperature change.
