650L Slimline Plastic Bunded Oil Tank – Black

Designed for properties where space is restricted, this 650L slimline plastic bunded oil tank provides reliable heating oil storage while maintaining a compact footprint. The narrow width allows the tank to be positioned easily alongside buildings, in side passages, or on smaller bases where wider tanks may not fit.

With durable polymer construction and an integrated bund system, the tank offers dependable protection for domestic kerosene heating systems while maintaining a clean and discreet 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 style of tank is often chosen as a slimline oil tank for narrow access, allowing heating oil storage to be installed in locations where standard tanks may be difficult to position.

Construction and Design

This 650L slimline plastic bunded oil tank is rotationally moulded from Medium Density Polyethylene (MDPE), a durable polymer widely used for heating oil storage due to its resistance to corrosion and outdoor weather exposure.

The structure forms a robust plastic oil storage tank with an outer bund that surrounds the internal fuel container, providing secondary containment. The black finish helps create a tidy and discreet installation, allowing the tank to blend more naturally into outdoor environments such as gardens, side passages, or service areas.

Installation and Safety Considerations

The slimline footprint allows this 650L slimline plastic bunded oil tank to be positioned in tighter installation spaces where wider oil tanks may not be suitable. A compact width of 610 mm helps support installation in restricted access areas.

The integrated bund provides secondary containment designed to help reduce environmental risk in the event of a leak. A secure locking lid also helps protect stored fuel from tampering or unauthorised access.

Installation should be carried out by a qualified installer, with the tank positioned on a suitable level base extending beyond the footprint and with appropriate clearances maintained from nearby structures.

Capacity and Usage

With a storage capacity of 650 litres, this tank is suitable for smaller homes or properties with lower heating oil consumption.

A 650 litre oil tank offers practical fuel storage for domestic heating systems while maintaining a compact footprint around the property. Its slimline design makes it particularly suitable for installations where space is limited but reliable heating oil storage is still required.

Durability and Longevity

The MDPE polymer construction offers strong resistance to corrosion, UV exposure, and weathering when installed outdoors. Unlike steel tanks, polymer oil tanks do not rust and typically require minimal maintenance over time.

The integrated bund system provides an additional layer of protection against spills while improving the long-term reliability of the tank. A 12-year manufacturer warranty (terms apply) provides further reassurance for homeowners investing in dependable heating oil storage.
