Quick Answer
For a generator, liquid propane is more suitable due to its higher energy density and lower pressure requirements, making it safer and more efficient.
Choosing the Right Propane Type for Your Generator
Liquid propane is the preferred choice for generators due to its higher energy density compared to vapor propane. This means that a smaller tank volume can store the same amount of energy, making it more efficient and space-saving. For example, a 20-pound tank of liquid propane can generate around 80-100 hours of runtime at a moderate load, whereas a vapor propane tank of the same size can only last around 60 hours.
Selecting the Correct Tank Size for Liquid Propane
When selecting a liquid propane tank for your generator, it’s essential to consider the required runtime, generator size, and fuel efficiency. A general rule of thumb is to choose a tank size that can store at least 10-20 pounds of propane per 100 hours of runtime. For a 3-kilowatt generator, a 20-pound tank would be sufficient for 80-100 hours of operation. However, if you need to power appliances for an extended period, a larger tank may be necessary.
