Reznor and Buderus
Combustion and Hydronics

The Best of Both Technologies

Founded in 1888, Reznor is the world’s oldest and largest manufacturer of industrial and commercial unit space heating products. It’s only logical that Buderus is the manufacturer of choice for boilers utilizing Reznor’s advanced burner, fuel delivery and combustion technologies. Buderus has manufactured quality boilers since 1731. That’s centuries of hydronics expertise! Buderus boilers are designed to meet strict safety and environmental regulations and are acknowledged as the world standard in high-efficiency hydronic heating. In 2007, Buderus was selected “Manufacturer of the Year” by the members of NAOSHM, the National Association of Oil Heating Service Managers.

Full three-pass, “Thermostream Design” operates under any water temperature

  • Optimum combustion, lower stack temperature and higher thermal efficiencies
  • Large heat area with minimal stack heat loss
  • 3.5” to 4” of thermal insulation provide low standby heat losses
  • Continuous low temperature operation under normal return water without requiring a minimum boiler return temperature.
  • Condensation and thermal shock are eliminated.
  • Balanced water flow throughout all boiler sections ... no hot spots or cold spots.
