No - Never!

If you use your Kelly Kettle without water in the chamber you run the risk of overheating and melting the inner chimney wall.  Just look at the pictures below.

Tell-tale signs that a kettle has been boiled dry are:

1) The inner chimney wall has either melted through or become so brittle that you can easily stick your finger through it!

2) The warning labels on the outside of the kettle have bubbled up, singed and perhaps disappeared altogether from the kettle!

NOTE: Your 2 year anti-leak warranty will not apply if you boil your kettle dry!
