The Burnham Revolution from U.S. Boiler Co. is a discontinued high-efficiency gas-fired water boiler with an AFUE of 88 percent. Six sizes are available ranging from 62 to 190 MBH.
The Revolution boiler operates on either natural or LP gas and can be configured for horizontal or vertical venting. The combustion process gives homeowners the option of using a direct vent for outdoor air or an induced draft for indoor air.
According to manufacturer’s information dating to 2010, the cast iron sectional design of the Revolution, coupled with the secondary heating surface’s diamond pin heat transfer system unique to Burnham’ Revolution boilers, allows the boiler to extract as much heat as possible. The system also employs an electric ignition and a step opening gas valve to ensure a smooth and quiet start-up. The burners are stainless steel and all piping and venting connections are found at the top of the unit for easy installation and maintenance.
