Tea water may be heated in many different types of containers. Often, people use kettles that make a whistling sound when water is hot. These kettles are often referred to as tea kettles.
Tea water may also be heated in a coffee pot, microwave, pan on top of the stove or hot water dispenser. In some cultures, the presentation of the tea and ceremonial tea pouring is more important than how the water was heated. In Japanese culture, even ceremonial tea water is prepared in a kettle or microwave and then boiled to bring out the true flavor, according to Shizuoka Tea.
