Description
For properties where installation space is limited but reliable heating oil storage is essential, this 1200 litre slimline plastic bunded oil tank provides a practical solution. Its narrow profile allows the tank to be positioned neatly in tighter locations around the property while still delivering a generous storage capacity.
With durable polymer construction and an integrated bund for secondary containment, the tank offers safe and dependable storage for kerosene heating systems.
What Is a Slimline Bunded Oil Tank?
A slimline bunded oil tank is designed to store heating oil safely in areas where installation space is restricted. It features a double-layer structure with an inner tank that stores the fuel and an outer bund that provides secondary containment to capture any potential leaks.
These tanks are often selected for properties that require slimline oil tank installation, allowing heating oil storage to be positioned in locations where wider tanks may not be suitable.
Construction and Design
This tank is rotationally moulded from high-grade Medium Density Polyethylene (MDPE), a durable material widely used for domestic oil storage due to its strength and resistance to corrosion. The UV-stabilised polymer helps maintain the tank’s appearance and structural integrity when installed outdoors.
The design forms a durable plastic oil storage tank with an integrated bund that surrounds the internal fuel container. This dual-layer construction provides additional environmental protection while maintaining a compact and functional structure.
Installation and Safety Considerations
The thin design makes the 1200 litre slimline plastic bunded oil tank well suited to installations where access or space may be restricted. With a width of 880mm, the tank can be positioned in locations where larger or wider oil tanks may be difficult to install.
The integrated bund provides secondary containment that helps reduce environmental risks associated with fuel storage. A locking cap is also included to help protect stored fuel from tampering or unauthorised access.
For properties requiring a bunded oil tank for domestic heating, this model offers both compact installation flexibility and modern safety features.
Capacity and Usage
With a capacity of 1200 litres, this tank provides practical heating oil storage for many residential properties as well as smaller commercial buildings.
A 1200 litre slimline plastic bunded oil tank can supply dependable fuel storage for homes using kerosene heating systems, while still maintaining a manageable installation footprint for properties where larger tanks may not be suitable.
Durability and Longevity
The tank’s rotationally moulded MDPE construction provides excellent durability and resistance to weather exposure, UV light, and corrosion. Unlike metal tanks, polymer oil tanks do not rust and require minimal ongoing maintenance.
The integrated bund adds an extra layer of protection, helping to contain potential leaks and extending the long-term reliability of the tank when installed outdoors.
To provide additional reassurance, the tank is backed by an industry-leading 12 Year Warranty, giving homeowners and installers confidence in its long-term performance.
