Burnham STMX399N-RH-KS, SteamMax, 399 Input MBtu, 82.5% AFUE, Hydrolevel, Residential Natural Gas Steam Boiler, Chimney Vent, 10 Year Warranty, Split block (8-12 sec.)(Knockdown)

The new benchmark for longevity, efficiency, and flexibility in gas steam boilers.

INDUSTRY-LEADING VALUE

• 10-year waterside corrosion warranty (residential only, under 300 MBH only)

INDUSTRY-LEADING DESIGN FOR RELIABILITY & PERFORMANCE

• Robust, corrosion-resistant cast iron sectional design extends heat exchanger life in a wide variety of water conditions
• Larger “steam chest” with increased steam disengaging area above a stable water line; wider internal waterways
• No heat transfer pins above water line, no crown sheet fins; greater corrosion resistance in critical areas
• More heat transfer pins below water line, provide ample heat transfer and efficiency
• Leak-free metal push nipples, not gaskets
• Steam risers in intermediate sections promote smooth steam flow
• 2” supply tappings, 2” skimming port tapping

INDUSTRY-LEADING SIMPLICITY FOR STEAM INSTALLATIONS

• Available pre-cut, near boiler piping kits for perfect piping every time (residential models 075-250 MBH)
• Rear, low-profile draft diverter clears low overhead and eases installation
• Tappings on both ends for greater piping flexibility and additional controls
• Packaged boilers or knock-downs, full, split or individual sectional assemblies
• Additional tapping (1.25”) for indirect/hydronic zone

Standard Equipment

The versatile V8 does it all!

Hot water or steam heat, the Burnham V8H can handle it. This efficient and highly adaptable boiler offers a variety of sizes and configurations to fit most home heating needs, and is available with an optional tankless hot water heater*. In addition, an optional high efficiency kit is also available, providing ENERGY STAR certified performance!

American-made quality and efficiency

The cast iron heat exchanger in the V8H is precision cast in Zanesville Ohio. Comprised of 100% recycled material and designed for years of reliable home comfort, It features a surface area which is up to 40% larger than many competitive models. This means that the boiler is able to heat up quicker, enabling a faster transfer of heat and greater efficiency. Every heat exchanger is water and pressure tested prior to assembly. The V8H is assembled in Lancaster, PA. Before it ships, every component used in the boiler is subject to strict standards of quality control and performance verification, which are constantly monitored during the manufacturing process. The end result is a boiler which will provide years of trouble free, efficient, and reliable service.

New boiler controls (water versions)

The new Intelligent Oil Boiler Control brings high end control capability to the V8H. By continuously monitoring all aspects of boiler operation, this control system is able to deliver increased efficiency and impressive energy savings.
