Product Overview

Intelligent Heating—by design
Buderus, the world leader in heating technology, manufactures the highest quality
boilers based on centuries of experience. With its innovative design and quality
manufacturing, a Buderus boiler will outlast and out-perform virtually any other
residential hot water system in the world.
The G215 and G315 are designed in Europe, where fuel costs are significantly
higher and environmental regulations are more stringent. Established in 1731,
Buderus uses state-of-the-art techniques in the design and manufacturing of its
boilers. The G215 and G315 are designed to maximize the heating value of every
ounce of fuel and built of the highest quality materials.
Constructed without a heat-consuming refractory or target wall, service and
maintenance calls are minimized, while fuel efficiency and heat transfer is maximized.
The full 3” thermal insulation around the boiler, including underneath, increases
efficiency by virtually eliminating standby and stack temperature losses.
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.
Complete your system for added comfort to your home!
Once you have a Buderus boiler you can add a Buderus indirect fired hot water tank,
an optional Buderus Logamatic control or both. The Logamatic control maximizes
your comfort and fuel savings, it will also accommodate specialized heating
applications such as radiant flooring. Combined, this premium heating system will
provide years of exceptional comfort and economy. . . for little more than the cost
of a standard replacement components.
Energy Savings
The ENERGY STAR program recognizes
products that meet or exceed an energy-
efficiency level set by the EPA. 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. This high efficiency
translates into dollars saved as well as
improved environmental quality.
Not only are the Buderus G215 and G315
boilers energy efficient, but they also
include the following installation and
maintenance features:
❚ Rear tappings and flue connection to
streamline appearance
❚ Baffles and clips for adjusting stack
temperatures
❚ Heavy gauge blue enameled jacket for
durability and attractiveness
❚ Full swing burner door hinged on either
the left or right allowing for easy access
❚ Front access plugs permit flushing of
the boiler’s interior
These features allow for easy installation
and thorough, proper cleaning in a
fraction of the time it takes with a
conventional boiler.
