  • Fully condensing high-mass firetube boiler
  • 316L stainless steel construction
  • Utilizes proprietary "EX" firetube design
  • Dual-fuel condensing - gas with #2 oil back-up
  • Gas-only condensing with premix burner
  • Robust, industrial design
  • 6000 to 12,000 MBH capacities
  • Low NOx emissions standard

 Designed for use in variable flow primary systems, the SwitchFire® boiler is a high-mass, fully condensing firetube boiler constructed of 316L stainless steel. The boiler is designed to handle variable flow pumping with a low waterside pressure drop and large water volume. With its dual-fuel (natural gas and #2 fuel oil back-up) capabilities, as well as a variety of other fuels, the SwitchFire is well suited for healthcare applications and other facilities requiring redundancy with alternate fuels. With its Weishaupt burner and controls, the SwitchFire offers industry leading efficiencies and performance with both natural gas and #2 fuel oil firing. The SwitchFire is also available as a gas only boiler with premix burner featuring up to 15:1 turndown and inherent low emissions.
