Harlequin 1100 Litre Slimline Bunded Heating Oil Tank
The Harlequin 1100 Litre Slimline Bunded Heating Oil Tank is designed for the safe storage of heating oil in domestic and commercial installations where space is limited.

The integrally bunded “tank within a tank” construction provides secondary containment, helping to protect the surrounding environment and ensure compliance with current oil storage regulations.
