Intelligent Heating – By Design

Buderus, the world leader in hydronic

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 G124X, G234X and G334X

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.

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. 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. All

models are atmospheric vented.

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.

GL-180M Gray Cast Iron:

Buderus GL-180M silicone injected, gray cast iron has excellent corrosion

resistance, exceptional casting characteristics and 40% greater flexibility and

elasticity as well as high thermal conductivity. Buderus developed the special

substances that are impregnated during the casting process to improve the

mechanical properties of cast iron. The graphite precipitates into smaller, modified

flakes which produce GL-180M cast iron with 40% greater elasticity and a high

silicone barrier for corrosion protection. Gray cast iron obtains its superior

material characteristics primarily from a high carbon (graphite) and silicone

content. Additional elements further enhance the properties of the GL-180M.

The graphite appears in two different forms in the microstructure: nodular form

producing excellent tensile strength and great elasticity and graphite flakes

producing excellent corrosion resistance against acidic combustion products.

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.

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.

Quality

Manufactured by Buderus, the world leader in cast iron boiler design and

production, the G124X, G234X and G334X construction consists of flexible GL-

180M cast iron, designed to resist thermal shock for long life and a high silicone

cast iron surface for excellent corrosion resistance. They each have staggered

contoured fins for optimum heat transfer and efficient operation, high precision

castings with steel push nipples, sectional construction, and deluxe, heavy gauge

blue enameled jacket for a clean finished appearance. There is a full 3" of thermal

insulation for minimal standby heat loss coupled with an integral draft diverter for

low profile. All models are easily converted to propane, and they also offer low

emissions with Premixed Burner Technology. Durable, quiet and efficient, Buderus

boilers are designed for many years of trouble-free operation.

Superior Design

Flueways of Buderus boilers have

a gas tight seal thanks to a tongue

and groove section design and

elastic high temperature resistant

sealing material. This seal is fully

pressed into the groove during

assembly.

G234X Boiler

Efficiency

The G124X, G234X, and G334X Series Boilers are available in natural gas or easily

converted to propane and feature AFUE ratings up to 84.8% for high efficiency

and top performance. Stainless steel premixed factory tested burners allow for low

emissions, and a full 3" of thermal insulation virtually eliminate standby loss and

stack temperature losses. Buderus boilers are designed for a long life, providing

efficiency and durability for the homeowner that is unsurpassed by the competition.
