Double Skinned Oil Tanks

A double-skinned oil tank is specifically designed for the storage of heating oil. Unlike a single-skinned tank, which has only one layer of protection, a double-skinned oil tank has two layers, with the inner tank surrounded by a secondary, protective outer tank. This double layer of protection helps to prevent leaks and spills, making double-skinned oil tanks a safer option for the storage of heating oil.

No, these terms are often used interchangeably.

Double-skinned oil tanks are considered safer than single-skinned tanks because they offer a double layer of protection against leaks and spills. In the event that the inner tank begins to leak, the outer tank will contain the leak. This reduces the risk of contamination or loss of expensive heating oil. Additionally, the double-skinned design makes it easier to detect and address any issues with the inner tank, as the outer tank provides a visual indication of any changes in the level of heating oil.

In the UK, double-skinned oil tanks must comply with regulations set forth by the Oil Firing Technical Association (OFTEC). These regulations cover a wide range of aspects, including the design and construction of the tanks, the materials used to make the tanks, the installation process, and the ongoing maintenance and safety requirements for the tanks.
OFTEC sets the standards for the design and manufacture of double-skinned oil tanks to ensure that they meet the highest safety and quality standards. At SG Tanks, all of the oil tanks we offer adhere to OFTC regulations.

To ensure the safety and longevity of your double-skinned oil tank, it is important to maintain it properly. Here are some key steps you can take to maintain your tank:
·         Regular inspections – regularly inspect your tank for any signs of leaks or damage, such as cracks or dents in the outer tank.
·         Cleaning – keep the area around your tank free from debris and any other potential ignition sources, and regularly clean the tank to prevent a build-up of dirt or debris.
·         Proper installation – make sure that the tank is installed properly and level, to prevent any leaks or spills.
·         Tank protection – if necessary, consider installing a secondary containment system, such as a bund, to further protect your tank from leaks and spills.
·         Ongoing maintenance – schedule regular maintenance checks with a qualified professional to ensure that your tank is in good condition and functioning properly.

The lifespan of a double-skinned oil tank can vary depending on a number of factors, including the quality of the materials used, the frequency and quality of maintenance, and the environmental conditions in which the tank is stored. However, on average, a well-maintained double-skinned oil tank can last between 20 and 30 years.
To extend the lifespan of your double-skinned oil tank, it is important to follow the maintenance and care instructions provided by the manufacturer and to schedule regular maintenance checks with a qualified professional such as SG Tanks.

Double-skinned oil tanks are constructed using steel for both the inner and outer walls. Having two steel layers provides strength and durability compared to plastic. Steel oil tanks stand up better to potential punctures or damage over time. The inner tank may have an epoxy coating for extra corrosion resistance. While plastic tanks are lighter, steel double-skinned tanks are considered higher quality and safer for domestic use.

Properly installed double-skinned tanks are less prone to leaks thanks to their dual-wall design. The outer skin provides an extra layer of protection and containment if the inner tank develops corrosion or holes from damage. This backup barrier makes leaks less likely. However, single tanks can also have long leak-free lifespans with proper maintenance. But for homeowners wanting extra security, the dual-layer design of double-skinned tanks provides added peace of mind and reduced leak potential.
