Do 500 Gallon Propane Tanks Expire?

Propane, unlike other fuels, does not “go bad” or lose its effectiveness over time. So, no matter how long your propane tank has been empty, you can keep using it.

How long will a 500-gallon propane tank survive before it needs to be replaced?

The 500-gallon propane tank is the most frequent of all the residential propane tank sizes. When the cold weather arrives, you should at least know how long a 500-gallon gas tank will keep a house warm.

A 500-gallon propane tank can last anywhere from one month to fourteen months and four days. Check the chart and graph for different sizes of homes further down for accurate times.

During the winter, the average US household uses roughly 750 gallons of propane. That means the average US household will require two 500-gallon propane tank fills per winter (500-gallon tank holds a maximum of 400 gallons of propane; the 80 percent safety rule).

We’ll take a deeper look at a 500-gallon tank’s lifespan. This will allow us to more precisely determine how long 500 gallons of propane will last in homes varying in size from 500 to 4,000 square feet.

To determine how long a 500-gallon propane tank will last in your home, we must consider the following factors:

  • Your home’s size. Larger dwellings demand more heating, and a 500-gallon propane tank will run out sooner than a smaller tank.
  • criteria for heating (location). Houses in the north of the United States demand more BTU heating than houses in the south. For instance, in Texas, a 500-gallon propane tank will last longer than in Chicago.
  • What is the severity of the winter? We will burn more propane in hard winters than in mild winters. According to the data for average US home winter use from 2010 to 2016, the 2013-2014 winter was the hardest, with an average usage of 830 gallons of propane compared to 750 gallons on a typical winter.
  • Your propane-powered heating units’ energy efficiency. For example, high-efficiency propane furnaces with an AFUE rating of greater than 90 will use less propane to produce the same amount of heat than furnaces with an AFUE rating of less than 70. A 500-gallon propane tank will last longer as a result.

6. Where can I have my propane tanks recertified?

How can you tell if a propane tank is past its expiration date?

A set of stamped markings can be found around the handle. These documents contain vital information regarding the tank’s origins as well as its capacity rating. A date should appear near the valve on the handle, showing the date of manufacturing. It’s usually written in the normal Month-Year format. It would say “06-20” if your tank was built in June of 2020.

Each tank also has a unique identifying mark, similar to those found on cars. This enables the US Department of Transportation and propane dealers to keep track of and maintain safety data for each tank in use.

Additional markings show the cylinder’s empty weight, which is recorded as “TW.” If you want to weigh the tank to see how much propane is left in it, this is useful. The “WC” stamp denotes the water storage capacity of the tank, which allows dealers to determine the exact amount of propane that can be securely stored inside.

It’s also very uncommon to see the identity of a requalifier imprinted into the handle area of your tank. You’ll be able to tell how near the tank is to hitting its expiration date if you know the manufacture or recertification date.

How can you know if a 500-gallon propane tank is in good condition?

If you have a propane tank for household energy, you’ve probably seen that the tank indicator displays 80 percent following a propane delivery.

Don’t worry, you’re not being duped, and your tank or gauge are in perfect working order. Although you utilize propane as a gas, it is stored in your tank as a liquid to allow it to expand and contract when the ambient temperature changes. The maximum fill percentage will always be set at 80%.

To figure out how much gas is in your propane tank, do some easy math. Simply multiply the tank’s capacity by the tank gauge reading.

For instance, if your 500-gallon tank has a gauge reading of 60%, it implies you still have 300 gallons of gas in your tank (500 x 0.6).

If you don’t want to do the math, here’s a chart that will tell you how much gas is left in your propane tank based on the size of your tank and the reading on your gauge:
