Instruction: Can you tell me about different types of hot water kettles?

Response: I'd be happy to tell you about hot water kettles. Hot water kettles are used to heat up water for beverages like tea or coffee. There are a few different kinds:
 - Stove-top kettles, which are placed on a stove and make a sound when the water is boiling.
 - Electric water kettles, which heat up using electricity rather than a stove. These can have many controls and contain thermostats to control the target water heat.
 - Gooseneck kettles, which can be electric or stovetop but feature a thin spout which is useful for making pour-over coffee.
