Harlequin 1000 Litre Slimline Bunded Heating Oil Tank
The 1,000 Litre Slimline Bunded Heating Oil Tank is designed for the safe storage of heating oil in domestic and commercial installations where space is limited. Its slimline footprint makes it ideal for positioning alongside buildings, within tight access areas, or in locations with restricted width.
Manufactured from durable Medium Density Polyethylene (MDPE), this integrally bunded oil tank offers long-term reliability, corrosion resistance and low maintenance. The bunded “tank within a tank” construction provides secondary containment, helping protect the surrounding environment in the event of an internal leak.
Supplied with a full bottom outlet fitting kit and Harlequin Smart Gauge with app-connected fuel monitoring, this model provides a complete and compliant oil storage solution.
Backed by a 10-year manufacturer’s guarantee (registration required with Harlequin).
