Single Skin vs Bunded Oil Tank
When it comes to storing heating oil, you must carefully consider the type of oil tank to install; single-skin or bunded oil tanks. While both serve the purpose of oil storage, they differ significantly regarding safety and environmental protection. This blog will explore the key differences between single-skin and bunded oil tanks, helping you decide on the right heating oil storage for you.
Single Skin Oil Tanks
Single-skin oil tanks consist of a single layer of steel or plastic, designed to hold the oil without any additional protective layer. They are often more affordable than bundled tanks, making them a popular choice for those on a budget. However, there are several key considerations to keep in mind:
Advantages of Single Skin Oil Tanks
- Cost-effective: Initial purchase and installation costs are lower than bunded tanks, which is appealing if you’re on a budget.
- Suitable for some low-risk areas: A single skin tank might suffice if you live in an area with minimal risk of oil leaks or environmental contamination.
Disadvantages of Single Skin Oil Tanks
- Higher environmental risk: Single-skins follow after their name; they have a single layer. This means that they are more susceptible to leaks and spills, potentially causing pollution. Even minor exterior or cosmetic damage can cause a serious leakage.
- Regulatory limitations: Some regions have strict regulations regarding installing single-skin tanks due to their higher environmental risks.
Bunded Oil Tanks
Bunded oil tanks, on the other hand, consist of two layers – an inner tank that holds the oil and an outer protective layer (the bund) that acts as a secondary containment system. The outer layer helps prevent leaks or spills from escaping into the environment, providing a safer option for oil storage.
Advantages of Bunded Oil Tanks
- Enhanced environmental protection: The secondary containment layer ensures that any leaks or spills from the inner tank are contained, reducing the risk of environmental pollution.
- Compliance with regulations: Bunded tanks often meet the strictest regulations set by environmental authorities, providing peace of mind and preventing potential penalties.
- Long-term cost-effectiveness: While initial costs are higher, bunded tanks are more durable and require less maintenance, making them a cost-effective choice in the long run.
Disadvantages of Bunded Oil Tanks
- Higher installation cost: A bunded tank’s upfront investment is more significant than single-skin tanks. However, it balances out over time due to lower maintenance and enhanced safety features.
- Space requirements: Bunded tanks are bulkier due to the additional protective layer, so ensure you have sufficient space for installation.
So, What Oil Tank Should I Choose?
Choosing between single-skin and bunded oil tanks depends on various factors such as regulations and budget. While single-skin tanks may be suitable for certain domestic installations, they come with a higher risk of environmental hazards. On the other hand, bunded tanks provide enhanced safety and environmental protection, making them the preferred choice for commercial, industrial, and larger domestic setups.
When deciding on the type of oil tank, it is crucial to consider your specific needs and the regulations in your area. Prioritising safety and environmental responsibility should be at the top of your decision-making process, ensuring a secure and sustainable oil storage solution.
You can also choose between metal and plastic tanks. See our recent blog for more information on whether you should opt for a plastic or metal oil tank.
