RBI Boiler Condensing FuteraFusionXLF

Futera Fusion

500–2,000 MBH | 4:1 Modulation
Unlike most condensing boilers and water heaters that produce the highest efficiencies at the lowest inputs, the Futera Fusion can attain efficiencies as high as 99% at full input. The full modulation firing system continuously varies the energy input to precisely match heating load without overfiring or wasting fuel.

The Futera Fusion’s heat exchanger was designed using a low-mass, gasketless primary heat exchanger with finned copper tube or Cupro-Nickel tubing – providing superior heat transfer, resistance to scaling and protection against thermal shock.

The condensing secondary heat exchanger is constructed from solid stainless steel and is designed to operate at the boiler’s full flow rate. The unit operates in full condensing mode at all times, while a state-of-the-art temperature mixing system protects the boiler’s primary heat exchanger. In addition, this design also offers a larger heat transfer surface area – more so than any competitive product currently available.
