  • Made in the USA · Every Burnham½ boiler is made in the U.S.A. To ensure the highest level of quality all Burnham boiler castings are produced "in-house" at our foundry in Zanesville, Ohio. Burnham is the only boiler manufacturer that can make such a claim.
  • Rugged cast iron sections... Superior pin design extracts the maximum amount of heat, reducing fuel consumption and saving you money.
  • Steel couplings... At Burnham we use steel couplings called "nipples" to join our cast iron sections. Steel nipples increase the longevity of your boiler. They are not affected by petroleum based chemicals, including antifreeze, which can deteriorate the cheaper rubber type gaskets substituted for steel push nipples in some competitors' boilers.
  • Fuel saving vent damper This automatically closes the flue to prevent heat from escaping up the chimney after the burner shuts off and reopens it again before the burner comes on.
  • Stainless steel burners... Stainless steel, unlike aluminized steel, ensure long life with no rusting.
  • Step-opening gas valve ...This type of gas valve enables the boiler to start on low fire and continue on to high fire safely and smoothly providing quiet ignition and long life.
  • Honeywell controls ...High quality brand name controls assure reliability and availability.
  • Combustible floor certified... The Series 2 boiler can be installed safely on most floors in your home without worry. No extra cost floor shield to buy.
