Roth Double-Walled Storage Oil Tanks

roth oil tank

Roth has established itself as a trailblazer in promoting environmental safety through its range of heating oil tanks, which come with one of the most comprehensive warranties and an insurance guarantee in the residential oil tank industry. These double-walled storage tanks are available in various sizes, ranging from 110 to 400 gallons. Let’s take a closer look at some of the top features offered by Roth for their storage oil tanks.

Outer Tank

Roth Double-Walled Storage Oil Tanks are designed with a key feature that sets them apart from other tanks on the market: their outer tank construction. Unlike traditional tanks, Roth’s storage containers are rolled seamed, which means that the galvanized steel segments are not welded but rather seam-rolled, tightly pressed together to create a superior, more robust outer hull. This outer shell is constructed with leak-proof, corrosion-resistant steel that can withstand impacts and is designed to be installed outdoors with a tank cover, providing maximum protection against the elements.

Inner Tank

Roth’s inner tank features a seamless construction made of high-density, blow-molded polyethylene. This design ensures that the tank is both leak-proof and corrosion-resistant, providing exceptional durability. By using plastic in its construction, Roth reduces the likelihood of corrosion caused by moisture. Additionally, this innovative design makes the Roth oil tank 50% lighter than traditional models, making installation and transport much easier.

Warranty & Insurance Guarantee

Roth stands behind their product with a 30-year limited warranty on manufacturing defects and workmanship-related issues. This warranty also covers any internal tank failures due to corrosion, which is the most common cause of tank failure in steel tanks. This exceptional warranty demonstrates the trust Roth has in its products and provides customers with added peace of mind.

Also, Roth distinguishes itself from its competitors by offering a $2 Million insurance guarantee for property damage or environmental impacts caused by their products. This insurance guarantee is a testament to the confidence Roth has in the quality and safety of their design. It provides customers with an additional layer of protection and ensures that they will be taken care of in the rare event of an issue.

Individual & Grouped Tank Options

Roth provides customers with the flexibility to choose between individual and grouped tank options for their storage oil needs. This means that homes with varying heating oil requirements can opt for a single tank or multiple tanks to accommodate their specific needs. Grouped tanks are ideal for larger family homes that require higher volumes of heating oil. The ability to customize the setup based on individual requirements is one of the many benefits of Roth’s products.


Roth Double-Walled Storage Oil Tanks undergo comprehensive quality testing to ensure their structural integrity, both internally and externally. This testing is carried out using advanced ultrasound technology.

Granby Home Oil Tanks

The tanks come in a variety of sizing options, providing homeowners with a range of options to suit their heating needs.

How Roth & Granby Oil Tanks Differ

Despite sharing similarities in their design and appearance, Roth and Granby oil tanks have distinct differences between them:

Oil Tank Sizing

There are variations in the sizes of Roth and Granby oil tanks. While Roth oil tanks are available in four standard sizes (110 gallons, 165 gallons, 275 gallons, and 400 gallons), Granby Standard tanks come in different sizes, offering 120-330 gallons configurations to choose from. Their EcoPlus comes in two sizes, 275 and 330 gallon.

Rolled Seam vs. Welded Heating Oil Tank

The method of construction differs between Roth and Granby oil tanks. Roth tanks have a roll-seamed design that is highly effective at preventing moisture from entering and oil from escaping. This construction method also reduces the risk of manufacturing defects. In contrast, Granby tanks are welded, which can result in inconsistent welds due to the heat and pressure required to join metal seams.

Warranty & Insurance Guarantee

While both Roth and Granby EcoPlus oil tanks offer a 30-year limited warranty that covers manufacturing defects and workmanship-related issues, their warranty coverage differs. Roth’s warranty applies to both indoor and outdoor installations, whereas Granby’s warranty covers outdoor installations with a 10-year limited warranty.

As for insurance guarantees, Roth stands behind their product with a $2 million insurance guarantee against environmental damages caused by their oil tanks. This level of protection is not available with Granby oil tanks.

Single & Grouped Home Oil Tanks

Roth and Granby oil tanks differ in terms of their tank options. While Roth offers the flexibility to choose between single and grouped storage tanks, which allows for a wide range of installation options for homes of varying sizes, Granby only allows for single-tank installations.

Quality Testing

While both Roth and Granby ensure the quality of their oil tanks, they use different methods of testing. Roth uses ultrasound to check for stress and ensure that the tank meets its high standards of craftsmanship. Meanwhile, Granby employs a comprehensive testing process that includes multiple tests on the tanks, as well as vacuum testing for the double-bottom tanks to ensure their integrity.

Roth or Granby? Tough Choice

When it comes to oil tanks, both Roth and Granby are great options with unique features that offer exceptional benefits to homeowners. Roth is known for its quality and sizing options while being environmentally conscious. Roth double-wall oil tanks offer peace-of-mind features that are not present in Granby tanks, including:

  • 30-year indoor and outdoor warranty with a $2 million insurance guarantee
  • Roll seamed construction
  • Ultrasound quality testing

On the other hand, Granby EcoPlus tanks are built with the latest technology and come with a 30-year warranty on manufacturing defects and any failure due to workmanship-related issues. Additionally, their tanks are tested three times and undergo vacuum testing on double-bottom tanks.

Whether you choose Roth or Granby, both companies are committed to providing safe and environmentally-friendly solutions for your heating oil storage needs. However, when it concerns the more robust double-wall oil tank, Roth is second to none. Whereas, if you’re in the market for a lower-priced single-wall heating oil tank, Granby offers a great product too.
