A heating oil tank is an important component of a home that is used every day. Getting regular service and any necessary repairs handled quickly will help prolong its lifespan but there’s a time when oil tank replacement is the only path forward. Luckily, replacing an aging oil tank can be a positive change.

Expected Lifespan of an Oil Tank

A professionally installed oil tank should last 20-25 years if it is regularly serviced. There are a number of conditions, however, that can affect the longevity of an oil tank such as tank location, exposure to the elements, material corrosion, and other considerations. It gets more important to inspect tanks as they get older to avoid an emergency.

Look out for these warning signs to tell you it’s time to replace your heating oil tank.

Visible Corrosion and Rust

Visible corrosion and rust on the exterior of the oil tank is one of the most obvious red flags. Extensive flaking and rust suggests advanced degradation which means you risk cracks, leaks, and potential tank failure.

Leaking Oil

Leaks indicate a problem with the tank that shouldn’t be overlooked. Even a slow leak poses an environmental risk and has the potential to escalate over time. Depending on the severity of the issue, the tank could be repaired or a replacement oil tank could be a better option.

Dents or Other Damage

Dents, scrapes, or other external surface damage warp the shape of the metal or plastic tank and compromise its stability over time. Impact with vehicles, fallen debris, and other heavy-duty objects are the most common cause of damage that causes serious problems.

Aging Oil Tank

Oil tanks can last for a while if they’re well-maintained, but they won’t last forever. Older oil tanks are known to have issues with corrosion, fatigue, and other problems that keep them functioning properly as they get older. It’s recommended to inspect tanks over 25 years old carefully because a replacement tank is often a more efficient option.
