Jan 18, 2017 · A boiler's job is to turn water into steam, which is denser than air and lighter than water. Air doesn't hold heat as well, and water is difficult to move, so steam is a good medium for transferring heat to where its needed. In most instances, a small furnace or heating device is attached and provides the heat to get the water steaming.
