Product Overview

A better way to heat your home
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.
Comfortable
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.
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.
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, allow the G115WS
to be thoroughly and properly cleaned in a fraction of the time it takes to clean a
conventional boiler.
G115WS
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.
The full swing burner door on the
combustion chamber allows for
easy, thorough and proper cleaning
in a fraction of the time it takes to
clean a conventional boiler.
It’s nice having peace of mind when it
comes to my heating needs. Buderus
goes the extra mile with their
products, using meticulous standards
and top quality materials for years
of reliable service. For example, all
sections are tightly joined and sealed
with profiled, beveled steel push
nipples and use a patented GL180-M
flexible cast iron.”
