The Boiler Room was an underground room below the Night Club in Club Penguin. Located here was the namesake boiler, which served as a power source for the entire island. Also located here was a large filing cabinet, which hosted old issues of the Club Penguin Times; however, only the most recent six were viewable.
The Boiler Room could be accessed by climbing down from a fake speaker in the Night Club, or from a door on the left side of the Underground Pool. Aside from the boiler and filing cabinet, the room was fairly sparse. On the back wall, there were a variety of tools and a fuse box, but these were only viewable in missions.
According the book Truth or Dare, the Boiler Room was once completely dark. Access was restricted to only a few penguins, and those few being simple cleaning crew or maintenance.
The Boiler Room was first opened to the public during the Underground Opening Party and has not changed since. It was still completely identical to when it first opened.
- Pins that are bolded are pins that could be made with the Pin Maker 3000.
- During April Fools' Parties from 2008 until 2011, the boiler was replaced with a giant pan filled with boiling water. There was a large sign on the wall which read "CAUTION: HOT" and a timer on the filing cabinet. When the timer finished, a jack-in-the box bursted out of a crate.
- During Medieval Parties, except for 2013, the Boiler Room is turned into a smithy. Various tools for forging are hung up on the wall, and the boiler is turned to a large furnace. There is a large smelter hanging from the wall known as the Pin Maker 3000. Over the years, multiple pins have been obtainable from the Pin Maker.
