Burnham MegaSteam™
High Efficiency Oil-fired Steam Boiler

Unique 3-Pass Cast Iron Design

The MegaSteam boiler has been exclusively
designed by Burnham engineers using a
3-pass, cast iron, sectional design that is
unequaled in the industry. MegaSteam
sections are produced in Burnham’s own
state-of-the-art foundry, and at 86% AFUE,
MegaSteam boilers are ENERGY STAR®
certified as the most efficient oil-fired
steam boilers available.

Superior Steam Quality

The MegaSteam 3-pass design helps produce
high quality 99% dry steam with low moisture
content while offering a high degree of
corrosion resistance. This outstanding steam
quality is incomparable in the industry and allows
MegaSteam boilers to outperform competitive
products in older steam applications where
steam quality is critical.

Expanded Product Warranty

In addition to Burnham’s standard limited 10-year warranty on the cast iron heat
exchanger, Burnham warrants each MegaSteam boiler for 5 years against waterside
corrosion, a common failure mechanism in steam boilers. The boiler’s unique 3-pass
design is instrumental in providing this important advantage.

MegaSteam’s expanded corrosion warranty is unmatched in the industry.
