Steam boilers can come in different sizes, oil or gas, and efficiency. Steam boilers are more complicated then water boilers.
For Residential Steam Applications
The Independence is a residential, gas-fired boiler for steam systems. It is available for either natural or LP gas and has AFUE ratings of up to 82%. Its large water volume and durable cast iron sections make it an ideal replacement for even the most challenging steam heating system. Standard equipment on the Independence includes cast iron push nipples that provide a permanent, watertight seal between sections, Honeywell operating controls, vent damper, and a rugged steel base assembly. A deluxe, insulated, powder-coated steel jacket completely encloses gas valves and burners, and reduces boiler heat loss. The exclusive Independence PV models have been specifically configured to operate as direct vented products for installation in homes with a damaged or irreparable chimney.
