3500 Litre Bunded Oil Tank - Harlequin

The Harlequin 3500ITE is a 3,500 litre horizontal bunded oil tank for large homes, farms, estates and commercial sites. It holds 3,297 litres nominal (3,471 litres brimful) and comes with extra safety equipment as standard, including overfill protection and a bund monitor.

Moulded from tough, corrosion-resistant Medium Density Polyethylene (MDPE), the tank is integrally bunded: an inner oil storage tank sits inside a separate outer containment tank. If the inner tank were ever to leak, the oil is held by the outer tank rather than escaping into the surrounding environment.

As an ITE model it arrives ready for a compliant installation, with a Harlequin Smart Gauge and a bottom outlet fitting kit supplied as standard. The Smart Gauge connects to your phone over Bluetooth, showing how much oil is left and roughly how many days until your next top-up.

For additional peace of mind, the tank is covered by a 10-year manufacturer's guarantee, subject to registration and Harlequin's terms and conditions.
