Propane is an excellent fuel source for many reasons, including grilling, source of heat, and enjoying a nice swim in your pool. However, you will need to invest in a propane tank if you want to enjoy the benefits of the fuel. You will also need to know how long propane tanks are suitable for before they expire or need to be replaced. The size of the tank is a significant factor in how long it will last.
How Long Do Propane Tanks Last?
Larger Propane Tanks
Larger propane tanks (above 120 gallons or underground tanks) are commonly used for residential purposes such as supplying the main source of fuel for a house. They do not need to be recertified. However, they should be inspected annually to ensure they are still safe to use. Homes that are 2,500 square feet or larger with various propane-based appliances are likely to use a 500-gallon tank. Propane tanks that are larger than 500-gallons are only typically used in commercial settings or large homes.How Long Can a 500-Gallon Propane Tank Last?
The 500 Gallon tank is one of the most commonly used sizes among homeowners. The average household will burn through a 500-gallon tank of propane in five months. The home furnace uses more propane than any other appliance. Therefore, even if the propane tank is used only for the furnace, it might still not last you a full year.How To Predict Your Propane Usage:
The more appliances that run off propane, the higher usage a home will have. For those wishing to understand the technical side of things, you will need to factor in the number of BTUs your appliances use and divide it by the number of BTUs in a gallon of propane (91,502). This number will give you the number of gallons of propane your home will consume per hour. Keep in mind, most appliances don’t run non-stop for the entire hour.Longevity of Propane Tanks:
Propane tanks are long-lasting and come with built in safety features to protect them. Compared to oil tanks, propane tanks are much more durable. It would be best if you had a professional inspect your tank annually to detect leaks or other defects in the tank.-
Above Ground Propane Tanks:
Above ground propane tanks are built to last. The average above-ground propane tank should last you about 30 years. Composite and aluminum cylinders can last even longer than thirty years. -
Underground Propane Tanks:
Underground propane tanks have a slightly longer lifespan than above ground tanks due to the fact that the ground protects the tank from harsh weather. On average, underground propane tanks last about 30-40 years. Factors affecting the longevity of underground propane tanks include the installation method and the kind of soil surrounding the tank. One way to protect your underground tank is to use an anode bag. Underground tanks are prone to electrolysis which can cause small holes in propane tanks and cause damage. Anode bags are bags that attach to the underground tank through a wire. They get buried with the tank and absorb harmful electrical currents which elongates your propane tank’s life. -
Small Propane Tanks:
Small propane tanks, such as standard 20 lb tanks, commonly referred to as barbecue propane tanks, operate slightly differently. Small propane tanks need to be recertified after 12 years.
