Coil burners are heating devices commonly used in kitchens for cooking. They consist of a metal coil that heats up when electricity passes through it, providing a direct source of heat for pots and pans. These burners are often found on electric stoves and are known for their simplicity and effectiveness in cooking a variety of meals. The design of coil burners allows for even heat distribution, making them suitable for tasks like boiling, frying, and simmering. While they are less common in modern kitchens compared to induction cooktops or ceramic glass cooktops, coil burners remain popular due to their affordability and ease of use.
