The Dominator™ Series from RBI offers the ultimate flexibility in boiler and water heater application at a competitive price. Efficiencies of 85.1% are among the highest available in non-condensing boiler and water heater designs. The Dominator incorporates all the latest technological advances that engineers, contractors, and building owners look for when specifying boilers and water heaters.

The Dominator can operate using mechanical room air for combustion or by drawing outside air directly as a sealed combustion product. Units can vent combustion gases vertically or horizontally with factory equipped draft-inducer kits.

Where mechanical space is limited the Dominator's stackable frame option allows units to be stacked two-high, adding valuable BTU's while keeping the footprint to the size of a single unit. Built-in serviceability features include a slide out heat exchanger that saves valuable service time by allowing the contractor to remove the heat exchanger for service or repair, without having to disassemble the entire unit.
