Boiler vs. Geyser — What's the Difference?

A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil.

A geyser (, UK: ) is a spring characterized by an intermittent discharge of water ejected turbulently and accompanied by steam. As a fairly rare phenomenon, the formation of geysers is due to particular hydrogeological conditions that exist only in a few places on Earth.
