Description
This 1000L slimline plastic bunded oil tank is designed for properties where space or access may be restricted but reliable heating oil storage is still essential. Its narrow width allows the tank to be positioned easily alongside buildings, within side passages, or on compact bases where standard tanks may be difficult to install.
With durable polymer construction and integrated secondary containment, the tank provides dependable storage for kerosene heating systems while maintaining a clean and discreet installation appearance.
What Is a Slimline Bunded Oil Tank?
A slimline bunded oil tank stores heating oil within a double-layer structure designed to improve safety and environmental protection. The inner tank holds the fuel while the outer bund forms secondary containment designed to capture leaks or spills.
This type of tank is commonly chosen where a slimline oil tank for narrow access is required, allowing heating oil storage to be installed in tighter locations where wider tanks may not fit comfortably.
Construction and Design
This 1000L slimline plastic bunded oil tank is rotationally moulded from Medium Density Polyethylene (MDPE), a durable polymer widely used in heating oil storage due to its strength and resistance to corrosion and weather exposure.
This construction forms a robust plastic oil storage tank with an integrated bund surrounding the inner tank for additional protection. The black exterior finish helps create a discreet installation, allowing the tank to blend more easily into garden spaces, service areas, or side passages.
Installation and Safety Considerations
The slimline footprint, with a width of 610 mm, allows the tank to be installed in tighter spaces where access may be limited. The bunded construction provides built-in spill containment designed to help reduce environmental risk.
A lockable lid with keys helps deter tampering and unauthorised access. Installation should be carried out on a flat, level, non-combustible base that extends beyond the tank footprint, with appropriate clearances maintained from buildings, boundaries, and ignition sources.
Using an OFTEC or APHC registered technician helps ensure the installation follows recommended guidance and protects the manufacturer’s warranty.
Capacity and Usage
With a storage capacity of 1000 litres, this tank offers practical heating oil storage for many domestic properties.
A 1000 litre oil tank is commonly chosen for homes using kerosene heating systems where reliable storage capacity is required while still maintaining a manageable installation footprint.
Durability and Longevity
The MDPE construction offers excellent resistance to rust, corrosion, and outdoor weather conditions. Unlike steel tanks, polymer tanks do not rust and require minimal maintenance over their lifespan.
The integrated bund design of the 1000L slimline plastic bunded oil tank provides an additional layer of protection against spills, helping ensure long-term reliability. The tank is supported by a 12-year manufacturer’s warranty to provide additional reassurance for homeowners.
