How long will my oil tank last?

Knowing the expected lifespan of your oil tank is crucial for any homeowner relying on fuel oil to heat their home. Oil tanks are designed to last for several years, but the actual lifespan of a tank depends on several factors. This article will explain the factors that determine the lifespan of oil tanks and how you can estimate the lifespan of your oil tank.

Typical Oil Tank Lifespan

According to industry experts, an average oil tank can last for about 15-20 years. However, the lifespan of a tank depends on several factors, including the quality of materials used to build the tank, the thickness of the tank walls, the soil composition surrounding the tank, and the quality of the installation. The lifespan will also be affected if the tank has been poorly maintained or frequently exposed to extreme weather conditions.

Factors That Affect the Lifespan of Oil Tanks

Quality of Materials: The material used to construct an oil tank plays a significant role in determining its lifespan. High-quality materials like fiberglass and plastic are less likely to rust or corrode compared to steel tanks.

Thickness of Walls: The wall thickness is another crucial aspect that determines the lifespan of a tank. Thicker walls can resist external pressure better and can withstand harsh weather better, thus, contributing to the lifespan of the tank.

Surrounding Soil Composition: A soil that is reactive or is naturally prone to corrosion can gradually eat away at the metal tank walls. When the corrosion starts, the oil can seep into the ground and cause environmental damage.

Quality of Installation: The conditions under which a tank is installed can also affect its lifespan. An adequately installed tank could last up to 20 years, but a tank that was poorly installed could fail as early as five years after installation.

Maintenance: Regular maintenance and inspection helps to detect leaks, cracks and other potential problems early on, preventing further deterioration and extending the life of the tank.

Estimating the Lifespan of Your Oil Tank

Here are three steps to help you estimate the remaining lifespan of your oil tank:

1.   Check the manufacture date: The manufacture date should be stamped on the tank and can help determine the age.

2.   Inspection: Check the tank for any signs of wear and tear like corrosion, rust, or leakage. Call in a professional to do a thorough inspection of your oil tank every 3-5 years.

3.   Historic Maintenance: Believing that your oil tank is in great condition? Recall the last maintenance that was conducted (like tank cleaning, urea treatment), improper or lack of maintenance can drastically cut the life of your tank.
