The RBI difference…
RBI “flexes” its strength by design. At its core is a piston-like heat exchanger engineered to eliminate the expansion and contraction stresses seen in today’s boilers by creating a temperature balanced symmetrical upper tube sheet reminiscent of a diaphragm that absorbs the stresses from this piston-like motion at any water temperature Delta.
Condensate is removed through FlexCore’s compact linear design resulting in ultra-high efficiencies with minimal corrosive effects. FlexCore scrubs every last bit of heat from the combustion gases keeping stresses low and efficiencies high at all modulation rates making FlexCore the most efficient boiler on the market today.
Rugged & Reliable Ignition System
A robust 8,000 BTU/h ignition system, Turbo Pilot is far more reliable and durable than any hot surface ignition and direct spark system. The Turbo Pilot gives burner ignition a surefire, powerful ignition source even in applications with fluctuating gas pressures.
UV detection keeps system diagnostics informed about performance; a technician can also use the observation port to confirm spark/flame without removing the pilot or burner assembly.
HeatNet 3.0® is an innovative, digital Boiler Management System that provides consistency and feedback through digital communication. By continuously monitoring several system characteristics, HeatNet 3.0 modulates boiler firing rates to maximize turndown ratios and maintain peak efficiency – no matter the load.

HeatNet 3.0 doesn’t just benefit stand-alone boilers; it is a valuable and cost-saving tool in operating a multi-boiler Master/Member network of up to 16 boilers, including mixed-size units. By functioning as a boiler management system, HeatNet 3.0 can incorporate a mixture of condensing boilers and non-condensing boilers to eliminate costly third-party, wall-mounted boiler control platforms.
HeatNet Online allows for real-time remote monitoring of boiler temperatures, limit circuit inputs, diagnostics and overall system performance.
This completely secure web-based monitoring program allows visual boiler feedback from anywhere through an easy-to-read dashboard. View boiler set points, service logs and system issues from your office computer, tablet or cell phone. HeatNet Online sends email text alerts for out-of-specification operation allowing for proactive responses to potentially harmful situations protecting the equipment and your
