1100 Slimline Steel Bunded Oil Tank

For properties requiring a narrow steel heating oil tank, this 1100 litre slimline steel bunded oil tank combines a substantial nominal capacity with a width of only 650 mm. The UK-manufactured construction provides a durable storage solution while the integral outer bund provides secondary containment around the inner tank.

The tank is manufactured with a 2 mm steel inner tank and 2 mm steel outer bund, with the bund designed to hold a minimum of 110% of the stated tank capacity.

What Is a Steel Bunded Oil Tank?

A steel bunded oil tank uses a tank-within-a-tank design. The inner tank stores the heating oil, while the outer steel bund provides secondary containment intended to capture fuel if the inner tank develops a leak.

This integrated containment design makes bunded tanks a practical choice where additional protection against fuel loss and environmental contamination is required.

Slimline Construction and Design

This 1100 litre model is approximately 1675 mm long but only 650 mm wide, making it useful for sites where available width is restricted. It uses 2 mm steel for both the inner tank and outer bund.

Standard connections include a 2 inch fill point with cap and chain, a 2 inch vent with cap, a 1 inch BSP bottom outlet and a connection for a clock contents gauge. The tank also includes lifting provision and internal bracing.

The standard finish is Holly Bush Green (RAL 14C39). Channel runners are available as an optional extra rather than being fitted as standard.

Installation, Maintenance and Guarantee

The tank should be installed on a level, load-bearing base suitable for the combined weight of the tank and its contents. General installation guidance recommends a concrete, paving-stone or stonework base extending at least 300 mm beyond the tank on all sides.

Installation requirements can vary by site, so the final installation should follow current regulations and guidance and be completed by a suitably qualified installer.

Steel tanks should be inspected regularly and maintained to protect the coating. Repainting with a suitable protective coating is recommended periodically, with manufacturer guidance indicating approximately every 18 months.

Do not arrange installation work or a fuel delivery until the tank has arrived and been checked.
