The gas-fired Futera Fusion™ now brings the field-proven performance of
Futera III 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 99% 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 2000 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
