Harlequin oil tanks are an investment in the future of your heating system and of your property. All Harlequin oil tanks feature integral bunding as standard. This means that each tank features a tank within a tank design and can, therefore, protect your valuable heating oil if the inner tank happens to split. Single skin tanks cannot provide this reassurance and the consequences can be costly and hugely damaging to the environment.

Harlequin HQi bunded oil tanks have been designed for customers who do not require the additional technology, as featured on all Harlequin ‘iTank’ Oil Tanks.

The 3500 Litre bunded oil tank is fully compliant with fuel storage requirements and suitable for the storage of heating fuels and waste oil. This range does not come with the oil monitor as standard.

Actual Capacity: 3370 Litres – Nominal Capacity: 3297 Litres

The Bunded Plastic Oil Tank is rotationally moulded from premium grade, oil resistant Medium Density Polyethylene. Ideal for the storage of Home Heating Oil.

The standard tank is delivered with:

  • 2″ Lockable fill point.
  • 4″ Lockable inspection point.
  • Lockable manhole access.

  • LRC Failsafe overfill prevention probe.
