Single-Walled vs Double-Walled: Which Oil Tank Is Right for You?

When it comes to fuel oil tanks, there are two options: single-walled and double-walled. If you’re looking to invest in a new one, it pays to learn the differences between the two. Here’s a guide to help you make an informed decision.

Single-Walled Fuel Oil Tank

A single-walled tank has only one layer of metal holding the fuel. This is a great choice for your home if you’re looking for a more affordable option. In some situations, a single-walled tank offers convenience, especially if there’s already an existing concrete structure that acts as a secondary containment layer. With this type of tank, you can rest easy knowing it meets the U.S. Environmental Protection Agency’s (EPA) Spill Prevention, Control and Countermeasure (SPCC) guidelines. These are put in place to minimize environmental risks in the event the tank suffers an oil leak.

Moreover, a single-walled fuel oil tank offers flexibility, especially in terms of placement. You can choose to place it either inside or outside your home. So, if you have little outdoor space to spare, the tank can be put in your basement or garage.

Double-Walled Fuel Oil Tank

Double-walled fuel oil tanks tend to be larger because of the added containment layer. This means that building a concrete structure is no longer required. It’s safe for the environment as well since it automatically adheres to the EPA’s SPCC regulations. 

In addition to being larger than a single-walled tank with equal fuel capacity, a double-walled tank also comes with a vacuum gauge that lets you know when a leak has occurred, giving you the time to take action to get it fixed. Also, the second layer protects the tank’s contents from rain, snow, sleet and other elements. The additional layer also means the tank is less prone to rust, which helps extend its lifespan.
