RBI provides the most complete line of finned copper tube boilers and water heaters available today.
RBI boiler models are available to fit any commercial application, from atmospheric to fan-assisted sealed combustion in a wide 100,000 to 4,000,000 BTU capacity range.

Reliable Construction
RBI’s commercial water heaters are the only units on the market that come standard with bronze headers across the entire product line. Greater installation flexibility is provided by left or right gas connections and left and right water connections.
RBI Condensing Products
With efficiency levels reaching 99%, it’s easy to assume that you are simply dreaming. But RBI’s series of condensing, gas-fired boilers ensures that efficiency this high is now within reach.
See RBI’s condensing products.
RBI Near-Condensing
Delivering efficiencies up to 88%, RBI’s selection of near-condensing copper finned boiler models are built for strength and reliability, tackling the toughest challenges of the commercial boiler market. Available in on/off, 2-stage, 4-stage and full-modulation with reduced footprints, all RBI near-condensing boilers are constructed for simple boiler installation and maintenance.

For Faster Heating:
- For 1½°F (-17°C) rise per hour: Increase BTUH input by 50%
- For 2°F (-17°C) rise per hour: Increase BTUH input by 100%
- Always select a heater equal to or larger than the requirement. Oversizing generally reduces fuel cost
