    The Burnham Series 2 boiler is a well-made and reliable cast iron water boiler. Because it's made in the USA, you know you are getting quality product that will last. The Series 2 comes equipped with a circulator - your choice between a Taco or Grundfos. Another added feature is a pre-installed low water cut off, protecting your boiler from damage if the water level gets too low. Popular for direct replacements, the Series 2 offers industry standard tapping locations for easy compatibility and replacement for your existing boiler.
  • Fully Featured
  • The Burnham Series 2 comes fully featured with a Grundfos circulator and pre-installed low water cut off (LWCO). A LWCO is vital, preventing damage or even an explosion in the event of low water levels in your boiler
  • Durable Construction
  • An American-made cast iron heat exchanger, insulated, powder coated steel jacket, and 1" of heavy gauge insulation all contribute to the longevity of the Series 2.
  • Integrated Controls

  • Thermal Purge
