Copper tea kettles are among the most efficient and long lasting tea kettles. In addition to being an attractive and timeless piece, copper tea kettles are also superior in heat conductivity.
Boiling water in a copper tea kettle takes less energy and heat than a regular kettle, reducing energy costs. It also takes less time to brew the same pot of tea at a lower temperature. Since high heat plays a large role in damaging other pots, this means copper tea kettles last longer than other types. Because of the heat conductive nature of copper, there are no hot spots and heating is very precise. Copper tea kettles are more expensive than other options and they do require regular cleaning and polishing.
