Residential Steam Boiler Basics - The Spruce

Steam boilers operate like a tea kettle. As water heats to a boil it builds pressure as it reaches the state of steam. Unlike hot water boilers which rely upon a pump to circulate the hot water, steam boilers use this pressure to move the steam through the piping system. The piping system of a steam boiler is usually a one-pipe or two-pipe system.
