Harlequin Oil Tanks: Industry-Leading Storage Solutions
When it comes to high-quality heating oil storage, Harlequin Oil Tanks are a top choice for homeowners and professional installers alike. Known for their innovative engineering and exceptional durability, Harlequin tanks are designed to withstand the harshest UK weather conditions while providing maximum security for your fuel. From compact residential units to large-capacity commercial systems, Harlequin offers a versatile range of storage solutions that combine style with substance.

Advanced Bunded Protection & Reliability
Every Harlequin bunded tank features a secondary containment system designed to prevent environmental pollution. This "tank-within-a-tank" technology ensures that in the unlikely event of a leak in the inner tank, the fuel is safely held within the outer skin. This makes Harlequin tanks fully compliant with UK Oil Storage Regulations and a safe choice for any domestic or agricultural installation.

Why Choose Harlequin?
Future-Ready (HVO Compatible): Harlequin tanks are fully certified for use with HVO (Hydrotreated Vegetable Oil), allowing you to transition to sustainable heating fuels whenever you are ready.

Premium 'iTank' Features: The iTank range is designed for the modern home, featuring sleek profiles and integrated equipment such as ultrasonic level sensors and premium filter kits.

Corrosion-Free Longevity: Made from high-grade, UV-stabilised polyethylene, these tanks will never rust or rot, and they carry a 10-year guarantee on the bunded shell.

Innovative Space-Saving Designs: Harlequin’s Slimline range is perfect for properties where space is at a premium, offering large storage volumes without a bulky footprint.

Expert Installation Kits Included
At The Tank Shop, we make installation easy by supplying Harlequin tanks with comprehensive kits. Most models include an Apollo electronic gauge and a high-quality filter valve as standard. Whether you are replacing an old single-skin tank or installing a new system, Harlequin provides the reliability and peace of mind you need for your home’s energy security.

Who are Harlequin and where are their tanks made?

Harlequin Manufacturing is one of the world's leading manufacturers of polyethylene storage tanks. Based in Northern Ireland, they have over 40 years of experience and are renowned for engineering high-quality, durable tanks that exceed standard industry requirements.

What is the Harlequin 'iTank' range?

The Harlequin iTank is a premium range of bunded oil tanks that feature an integrated 'tank-within-a-tank' design. These tanks are famous for their modern aesthetic and come equipped with high-spec equipment, including an ultrasonic level gauge and an installation kit as standard.

Are Harlequin tanks HVO compatible?

Yes, Harlequin has been at the forefront of the transition to renewable fuels. Their entire range of bunded oil tanks is HVO-ready, meaning they are fully compatible with Hydrotreated Vegetable Oil, allowing you to future-proof your heating system.

What warranty does a Harlequin bunded tank carry?

Harlequin offers a 10-year warranty on their bunded oil tank shells, provided the tank is registered and installed by a qualified OFTEC technician. Their single-skin models typically carry a 1-year or 2-year warranty.

What is the difference between Harlequin Slimline and Horizontal tanks?

Slimline tanks are designed with a narrow width (often under 700mm) to fit through garden gates and down side passages. Horizontal tanks have a wider, lower profile, which provides excellent stability and makes them easier to hide behind walls or hedges.

Do Harlequin tanks include monitoring equipment?

Most Harlequin bunded tanks supplied by The Tank Shop come with a factory-fitted Apollo or Watchman Sonic electronic gauge. This allows you to monitor your fuel levels wirelessly from a plug-in receiver inside your home.

How secure are Harlequin tanks?

Harlequin tanks are designed with security in mind. They feature lockable lids that protect the fill point and inspection hatch, helping to prevent fuel theft. Their heavy-duty MDPE construction also makes them highly resistant to impact and tampering.

Are Harlequin tanks compliant with UK regulations?

Yes, all Harlequin tanks are manufactured to the highest standards, including EN13341 and ISO 9001. They are LABC (Local Authority Building Control) certified and OFTEC approved, ensuring they meet all UK environmental and building safety regulations.
