Propane is one of the most widely used fuels in countries across the world. Many conventional machines including vehicles, water heaters, generators and so on use propane for fuel. Propane is most commonly used because it is one of the cheapest and most abundant types of fuels available. The fuel is highly combustible which makes it more energy efficient.
Another key feature of propane is its longevity. Many companies reduce costs by investing in products that run on propane for this reason. Propane is slow burning and therefore can last longer than other natural fuels.
