Canned heat is a type of portable fuel commonly used for cooking and heating. It typically consists of a flammable gel or liquid contained in a metal can. This fuel is popular for camping, outdoor activities, and emergency situations because it is easy to use and requires no special equipment to ignite. The fuel burns cleanly and produces a steady flame, making it suitable for heating food or beverages. Canned heat is often used with small stoves or as a heat source for fondue pots. It is a convenient option for those who need a reliable heat source without the need for electricity or complex setups.
