A heating oil tank is built to last – but not to last forever.
So how long should your oil storage last? The honest answer is “it depends.” Some factors that influence the lifespan of your heating oil tank include:
The good news is that modern heating oil storage tanks have come a long way from designs of the past, offering virtually leak-proof performance for decades. Let’s take a closer look at modern oil storage tanks, and why they’re worth the investment if you’re ready for a heating oil tank upgrade.
In the past, oil tanks were constructed almost exclusively from steel, which were prone to internal corrosion in the presence of condensation (water). Steel tanks are still available today, but they are built to a much higher standard than in the past.
To get a better idea of the range of lifespans for today’s single-wall interior steel heating oil tanks, here’s a summary from inspectapedia.com.
The most significant changes in oil tank design in recent years, however, have come in the use of alternative construction materials such as fiberglass and polyethylene. These materials are often used as the inner lining of a double-walled storage tank; when combined with leak detection technology, these materials make today’s oil storage tanks virtually leak-proof.
Double-walled oil storage tanks also last significantly longer than their all-steel, single-wall counterparts – about twice as long. You read that right: a properly maintained double-walled heating oil can last 50 years or more, according to inspectapedia.com.
Heating oil tanks are built to last, offering a relatively long lifespan when properly maintained.
Above-ground tanks, commonly found in garages, basements, or outdoors, typically last around 25 years and, with good care, can sometimes exceed that. These tanks are easier to inspect and maintain, which can help extend their life.
Underground tanks, on the other hand, have shorter lifespans, usually closer to 15 years, as they are more susceptible to environmental factors like soil moisture and corrosion. Regular inspections and maintenance are key to ensuring the longevity and safety of both types of tanks.
Most heating oil tank failures are caused by corrosion of the tank from inside it.
The path to internal corrosion begins with condensation building up on the bare parts of your heating oil tank’s interior walls. That condensation drips down into your heating oil and, since it’s denser, quickly sinks to the bottom of the tank. This creates an optimal environment for the development of sediment, which, over time, leads to internal corrosion of your tank and, ultimately, tank failure.
While you can’t see inside your tank, there are ways you can detect corrosion by inspecting your tank’s exterior. Signs to look for include:
If you detect any of these problems, contact us immediately and we’ll come look at it. The JW Pierson team is proud to offer no-fee tank inspections to keep your heating system running smoothly. If you’ve noticed warning signs of a failing tank, don’t wait—our experts are here to help. We can quickly replace a compromised tank, preventing costly oil spills and cleanup costs that are usually not covered by your homeowner’s insurance.
Here’s a smart tip from our team: keeping your heating oil tank full can significantly reduce condensation and the risk of corrosion. That’s why we recommend filling your tank as soon as the heating season wraps up. By doing so, you’ll minimize condensation and enjoy the convenience of a full tank ready to go when colder weather returns.
As you can see, modern heating oil tanks are built for life – and, in the case of the Roth heating oil tanks we sell, warrantied for thirty years! All in all, a great investment if you’re ready to upgrade your oil tank.
That’s especially true now: thanks to our Spring Ahead for Savings Specials, you’ll $250 on a new Roth double-wall oil tank installation. BUT HURRY – this offer expires on Memorial Day 2021!
