Does Propane Go Bad?
Do you rely on propane for your home? Due to the seasonality of propane, there’s a common misconception that, like other fuels, propane can “go bad” over time. This leads to worries about the safety, efficiency, and lifespan of stored propane, and it can leave you uncertain about the best way to manage your energy source.
While propane users should be aware of relevant expiration dates associated with their home heating system and fuel sources, we’ve answered the common questions we get about propane and propane tanks in this blog. Continue reading to find out why propane is actually a reliable option for your home.
How long can you keep propane stored?
Many fuel sources, such as gasoline and diesel, tend to degrade over time, losing potency and efficiency. On the other hand, you’ll be relieved to know that propane can be stored, in safe conditions, indefinitely. Unlike other fuel sources, propane will not lose potency over time when stored properly. There is no expiration date on a propane tank, however, it is essential to ensure equipment is inspected regularly for safety and efficiency.
Does propane dissipate in the tank?
Propane, stored as a liquid in your tank, expands into a gas that is then funnelled through your system to power your appliances. During warmer weather, the evaporation process accelerates, converting propane into its gaseous form faster. To ensure safe and efficient operation, it’s critical to only fill the tank to 80% capacity, in order to allow sufficient room for the propane to expand without over-pressurizing the tank. While propane can change states from liquid to gas, it won’t dissipate or leak away as long as the tank is securely sealed.
What happens if you use old propane?
While propane doesn’t have an expiry date, the concept of using “old propane” may worry you. For most customers, propane is cycled through the system regularly. For those who use propane primarily for heating during the colder months, you may wonder if the propane that has been sitting in the tank over the summer is still safe and effective to use in the next heating season. Propane chemical properties allow it to retain its effectiveness indefinitely, regardless of how long it’s been stored. Whether you use your propane frequently or it sits in the tank for an extended period, it will still burn efficiently and cleanly when you need it.
In fact, propane’s long shelf life makes it an excellent choice for rural homeowners who value dependability and low maintenance.
How do you tell if a propane tank is expired?
Knowing the age of your propane tank and understanding when it might be nearing the end of its safe lifespan is important. On the data plate, typically found near the top of the tank, you’ll find a date stamped in month-year format. This will tell you the date of manufacture. If you see a number like “05-18,” for example, this means your tank was manufactured in May 2018.
How long do propane tanks last?
Propane cylinders are good for 10 years, while larger tanks, like the ones that are used to heat your home or power your appliances, can last for 25 years. If it’s been more than 10 years since that date, it’s time to get your tank inspected by a professional.

How old can a propane tank be before it needs to be recertified?
When you decide to install a propane system in your rural home, one of the first steps will be a propane tank inspection. This initial inspection ensures that the tank is in good condition, that it has been manufactured according to the appropriate safety standards, and that it is fit for its purpose. Our trained professionals at Primemax Energy will check for any signs of damage or manufacturing defects that could compromise safety. They will also ensure that the tank is correctly situated for safe and efficient operation.
Following this initial installation and inspection, propane tanks must be reinspected every 5 years. Regular inspections allow for the early detection of any potential issues, such as corrosion, leaks, or damage to the pressure relief device.
When do propane cylinders need to be recertified?
Cylinders must be recertified and re-stamped every 10 years by a qualified gas technician. The manufacture date will be stamped on the collar.
