The Boiler is a mechanical device found in the Boiler Room that gives heat and electricity to Club Penguin. The boiler seems to not be securely fixed to the ground since it had been stolen by the Test Robots in a Club Penguin: Elite Penguin Force mission and as it sometimes has been moved during parties
- During April Fools' Parties it becomes a pan of hot water.
- This boiler provides power to the entire Club Penguin Island.
- Herbert P. Bear tried to steal the boiler to make himself warm in PSA Mission 8, but he accidentally hit the boiler with his spanner, causing it to overheat and become unstable. The Secret Agent was successful in fixing it.
- In addition, on November 7, 2013 preceding Operation: Puffle, Herbert's footprints were spotted surrounding the boiler, as he had earlier on sabotaged the boiler and stolen parts from it.
