The life expectancy of a propane tank is not constant as it depends on various factors, including the size, the use of the tank, and maintenance.

Underground Tanks

Underground tanks have a life expectancy of 20-30 years. Some factors that will influence the life expectancy of these propane tanks are the weather, soil type, and how they were installed. Underground propane tanks that were adequately installed have the potential to last for a long time.

When Does Propane Go Bad?

The simple answer to this question is that propane is one of the most storage-friendly, resilient, and stable energy sources that do not have an expiration date. Propane gas does not degrade over time, thus a long shelf life.

However, if the container used to store the gas expires or goes bad, that is when you can say that propane gas has gone bad. To prevent such a situation, you need to make sure that you take good care of the tank used for propane gas storage.

What Is The Shelf Life Propane?

If well stored, propane can last for decades as it is one of the most storage-friendly energy sources.

Unlike other energy sources such as diesel, kerosene, gasoline, and heating oil degrading over time, propane does not have a shelf life. It is a resilient and storage-friendly source of energy. Therefore, propane gas does not go bad in a storage tank. What can go bad is the container used to store it, and this is why you need to ensure that you maintain the storage tank well.

However, propane gas stored in a tank can freeze in rare situations when the weather is icy. During winter, propane gas may shrink. Consequently, the propane gas level in the tank shrinks, making you think that you could lose the gas through unprecedented leaks.

Generally, cold conditions have a negative impact on the heating oil. It thickens in the tank in a condition known as gelling. When gelling occurs, it can reduce the flow of oil to the furnace or boiler and result in the system’s shutdown. If that happens, you might be compelled to spend a lot of money trying to rectify the problem.

The best way to prevent such a situation in the future is to ensure that your propane tank does not get low.

How Long Does A Propane Tank Last?

A recertified propane tank is deemed to be in good condition after 5-12 years, depending on the type of recertification.
