The Harlequin 1225l slimline is a popular mid-range bunded oil tank suitable for domestic and light commercial installations. With an 840mm width it fits comfortably through most garden gates, while offering more capacity than entry-level slimline models. Rotationally moulded from uv-stabilised mdpe, it is lightweight, non-corrosive and built to last.
