A Revolutionary Boiler Design

OMNI’s unique design provides high efficiency. The OMNI cast iron boiler is a revolutionary idea in industrial heating. It utilizes the highly efficient, extremely durable Scotch Marine design principle that has been proven in decades of use in large commercial and industrial heating systems. Boiler is manufactured in Germany, and sections are assembled there as well.

Easy to Maintain

Swing out door and rear cleanout ports allow money saving serviceability. Unlike traditional boilers which require hours of disassembly, the OMNI’s hinged front door provides instant access to all of the boilers’ heat transfer surfaces. All service and cleaning can be completed literally in minutes, creating additional savings. A clean boiler is a more efficient boiler.

OMNI 3 Pass Design

This unique wet base design passes the hot combustion gases three times through the boiler under negative pressure. This maximizes the gases contact with the boiler’s water surface area.

The result: 84% Efficiency, Burns Clean, Zero Smoke
