Does Propane Expire?

Written on: February 26, 2024

Propane Won’t Degrade Like Other Fuels

propane Wakefield, MA Another great way you get peace of mind with Broco Energy as your propane supplier is that the fuel we put in your tank doesn’t have a shelf life or an expiration date. In other words, propane doesn’t degrade as other fuels do, such as gasoline, kerosene, diesel and heating oil. So, as long as your propane tank is properly maintained, the propane that sits inside will be perfectly fine, and its potency and efficiency will not be affected even if it rests in storage for a long time.

That’s just one more reason why propane represents an extremely smart choice as a fuel source for all types of home appliances and other equipment in your home. This includes water heaters, furnaces, boilers, space heaters, fireplaces, and whole-house generators.

Can Propane Freeze in My Tank?

Another issue you don’t need to worry about is your propane supply freezing inside the tank. Propane’s freezing point is about -306°F. This temperature could only be produced in a laboratory setting because this freezing point is too cold to happen anywhere on Earth—including the South Pole.

However, we should note that propane does have a boiling point of about -44°F. What does this mean? Well, at this temperature, liquid propane can no longer turn into a gas. Now it is possible, if rare, to reach that temperature, but it would be very rare. For trivia buffs, the coldest recorded temperature in Massachusetts was -40°F in January 1984.

Cold Weather Affects Tank Pressure

The main concern during extremely cold winters is not propane freezing, but a loss of pressure in your tank.

Like all liquids, propane contracts in the cold. When it does, the volume of liquid propane in your tank shrinks, resulting in a loss of pressure. If the pressure gets too low, propane won’t be able to reach your gas burners.
