Can the kettle be used without water in the chamber?
No - Never!
It is physically impossible to melt the chimney, if the kettle is used correctly and full with water when in use. If you use your Kettle without water in the chamber or, allow it to boil dry, then you run the risk of overheating and melting the inner chimney wall. This is especially the case with Aluminium (Kettles) which has a lower heat threshold than Stainless Steel. We have no recorded cases of any of our Stainless Steel kettles melting.
Please look at the pictures below - all of which are Aluminium Kettles and have been used without water or, allowed to boil dry.
The tell-tale signs that a kettle has been boiled dry entirely consistent and are:
- The inner chimney cracks & bubbles up (early stages of overheating)
- The inner chimney wall has either melted through completely or become so brittle that you can easily stick your finger through it!
- The warning labels on the outside of the kettle have bubbled up, singed and perhaps disappeared altogether from the kettle! This is an extreme case - see bottom right picture.
NOTE: Our 2 year anti-leak warranty does not cover mis-use and does apply if the kettle is boiled dry!
