Buderus SSB Industrial

Buderus SSB Heavy Commercial Boilers

Pre-mix, Condensing Buderus SSB Heavy Commercial Boilers

The Buderus SSB Industrial Boilers were designed to deliver the highest quality, flexibility and dependability in the industry.

With a small footprint (31.5” x 36”), minimal clearance requirements and output range from 800 to 8,192 MBH, these boilers can be utilized in almost any application.

If redundancy is what you’re looking for, then these boilers are the answer. Each SSB Industrial Boiler has two fully independent heat exchangers which can be operated individually if necessary.

In addition, the SSB1000TL boilers have an innovative design which allows up to 4 of these boilers to be cascaded on either side without any additional purchased venting parts or accessories.

Ultra-efficient & Dependable Design

  • Efficiency levels up to 96.8% with up to 80:1 turndown capability.
  • Built-in redundancy with up to 16 heat exchangers (2X, SSB1000TL4).
  • Proven 316L stainless steel water tube heat exchanger with dual parallel helix tubes.
  • Consistent combustion with modulating gas valve and stainless steel mesh burner.
  • Easily accessible components with removable panels on all four sides of the boiler.
  • 10-year full heat exchanger warranty, with a 2-year warranty for parts.

Flexible Installations with Modern Controls

  • All connections (exhaust, intake, supply, return and gas) available on both sides of the unit.
  • Easily connect up to 4 boilers with zero additional purchased parts or accessories (SSB1000TL only).
  • Up to 8 boilers can be linked together for total capacities up to 8,192 MBH (2 sets of SSB1000TL4, or 8 stand-alone)
  • Small size (31.5” x 36” x 70”) and minimal clearances allow installation in almost any location.
  • 7” external touchscreen display for intuitive system control and monitoring.
  • Internal HMI screen allows for advanced boiler adjustments.
  • Field-convertible to either natural gas or liquid propane.
  • Communication with Modbus, BACnet and LonWorks protocols.

Buderus SSB Commercial Condensing Boilers

Buderus SSB Light Commercial Boilers

96% Efficient Buderus SSB Light Commercial Boilers

For maximum efficiency, Buderus SSB Boilers achieve consistent combustion throughout the entire length of the burner tube due to a patented laser perforated design.

Buderus SSB Boiler Series

The new Buderus SSB Series was specifically tailored by Bosch to give you all the same features and benefits from a small residential boiler through a large commercial cascade application.

Single platform design for all Buderus SSB’s makes installation and commissioning easy, regardless of the output required.

With an efficiency of 96%, the Buderus SSB is loaded with standard features that include:

  • 5:1 turndown ratio
  • onboard control that includes weather compensation
  • mod-bus connectivity
  • a 2 wire cascades link
  • practical control solutions for any application
  • push terminal wiring
  • a host of venting options.

The Buderus SSB boilers are CSD1 compliant thanks to built-in LWCO and adjustable manual reset high limit.

Not just another stainless steel boiler

  • Peace of Mind: 10 years full on the heat exchanger, 5 years on parts and labour (residential) and 2 years on parts and no labour (commercial).
  • Reliability: heat exchanger and entire burner assembly are made of 316L stainless steel.
  • Comfort: providing comfortable heating with or without indirect domestic hot water tank from a small studio unit up to commercial cascade applications.
  • Ease of Installation: automatic control unit for gas-fired appliances with a premix burner and a pneumatic air-gas system. Factory built-in LWCO and Safety Temperature High Limiter w/ manual reset.
  • Control: the SSB has multiple parameters, for heating, domestic water heating, and circulator pump, each designed for the most common applications.
