How old is a kettle old?

The age of a kettle can vary widely depending on its type and usage. Generally, electric kettles can last about 5 to 10 years, while stovetop kettles may last longer, often 10 to 20 years or more with proper care. Signs of aging include decreased efficiency, rust, or mineral buildup, which may indicate it's time to replace the kettle. Ultimately, a kettle is considered "old" when it no longer functions effectively or safely.
