The gas-fired Futera Fusion™ and Fusion XLF now brings the field-proven performance of Futera III and XLF Modulation boilers and water heaters to the ultimate levels of efficiency and reliability. This innovative design is the ideal choice for applications with low operating, return, or make-up water temperatures. Unlike most condensing products available today which publish the highest efficiencies at the lowest inputs, the Fusion is capable of attaining efficiencies as high as 98% at Full Input! The full modulation firing system continuously varies the energy input to precisely match heating load without over-firing and wasting fuel. This provides extremely high part-load efficiencies. System sizing is made simple with models available from 500 MBH to 4000 MBH.
The condensing secondary heat exchanger is solid stainless steel and designed to operate at the boiler’s full flow rate. It operates in full condensing mode at all times, while a state of the art temperature mixing system protects the boiler’s primary heat exchanger. There’s simply no better way to protect an owner’s investment. This design also offers a larger heat transfer surface area than any competitive product currently available.
