Burnham Commercial's promise to deliver the best
continues with the Series 8H. The features and efficiency
of the 8H boiler make it ideal for single and multiple boiler
applications. Offering space heating, or a combination of
heating and domestic hot water, the Series 8H has a compact
design which easily adapts to existing piping arrangements,
boiler room requirements, and system heating needs.
American-Made Cast Iron Construction–
BC25-HSi
Burnham Commercial’s unique BC25-HSi cast iron formula
has an extremely high silicon content,
making it stronger and more flexible. It
offers better thermal shock resistance
and greater heat transfer capabilities
than other cast iron products. BC25-
HSi's properties allow Burnham
Commercial to maintain the highest
level of quality from start to finish, and
provide a product that is optimized for
hydronic heating applications .
• Manufactured with Quality
All cast iron sections for Burnham
Commercial boilers are manufactured
at Burnham Foundry, LLC in Zanesville,
Ohio, ensuring quality and availability
of boiler sections.
• Cast Iron Nipple Difference
The gaskets that other manufacturers
use to connect boiler sections can
break down if they come in contact
with oils, boiler flue gases, corrosion
inhibitors, pump lubricants, and
antifreeze. Burnham Commercial is
committed to safety, reliability and
durability. That's why the Series 8H uses cast iron nipples
instead of gaskets in this critical area. The Series 8H's
cast iron nipples remain unaffected by those elements,
ensuring long life and eliminating costly repairs These
vital components are precision cut and will last the life
of the boiler. They expand and contract with the sections
they connect, ensuring the overall integrity of the section
assembly.

83% Efficiency
With today's high energy costs, the need for efficiency
has never been greater. The Series 8H has been designed
to offer high efficiency without sacrificing long term
reliability.
• Heat Exchanger Design
The cast iron heat exchanger on
the Series 8H features a pinned
heating surface. These multi-
faceted pins allow the heat
generated from the combustion
process to be transferred to the
cast iron from a number of angles, which contributes
to the boiler's overall efficiency. A vertical flue design
extracts heat while maintaining low draft losses.
• Deluxe Insulated Jacket
The jacket on the Series 8H is
lined with three inches of
insulation. This serves to reduce
jacket and standby heat losses,
further conserving energy. The
jacket itself is powder coated,
insuring a scratch resistant, long
lasting finish.
Two Packaging Options
Knocked-down 8H units are easy
to handle and maneuver at the
job site. Optional containerized
skid (shown) can be stacked,
providing warehousing and job
site convenience. Packaged and
wired units provide fast and easy
installation. A reinforced shipping
container protects against damage.
