What's Included
- Harlequin UGD1400 Bunded Underground Oil Tank
- Tigerloop® De-Aerator
The Harlequin UGD1400 Bunded Underground Oil Tank is designed for properties where preserving outdoor space and maintaining the appearance of the landscape are key priorities. With its 1400-litre capacity and fully underground installation, it provides substantial fuel storage without impacting the visual appeal of gardens, driveways, or outdoor areas.
Ideal for homes with limited space or carefully landscaped surroundings, it offers a discreet solution for modern heating fuel storage.
Double-Walled Construction for Enhanced Protection
The UGD1400 features a robust double-walled design, providing an additional layer of protection compared to standard tanks. The inner tank is moulded from durable medium-density polyethylene, while the outer shell is constructed from glass reinforced plastic (GRP) for exceptional strength and durability.
The tank also incorporates an interstitial leak detection monitor and complies with best practice guidelines outlined in PPG27 and BS5410, helping provide confidence in long-term performance and environmental protection.
Designed for Easy Access
A lockable hinged access lid with a brick-effect surround provides convenient access for filling, inspections, and maintenance while blending neatly into surrounding landscaping. The redesigned lid helps reduce the risk of water ingress while offering a more attractive and discreet finish than traditional access covers.
This makes the UGD1400 particularly suitable for installations where appearance is just as important as functionality.
Advanced Monitoring and Safety Features
The tank includes a comprehensive range of safety and monitoring equipment as standard. An ultrasonic contents gauge allows accurate fuel level monitoring, while the overfill prevention valve helps protect against accidental overfilling during deliveries.
The integrated leak detection monitor and dip tube between the tank walls provide additional reassurance, helping identify any issues quickly and effectively.
Complete Underground Fuel Storage Solution
Supplied with a Tigerloop® De-Aerator and Ecoflex top offtake fitting, the UGD1400 provides a complete underground fuel storage package. The top outlet configuration helps reduce the risk of fuel leakage, while the Tigerloop® unit promotes efficient fuel delivery to the appliance.
These features make it one of the most advanced domestic oil tanks available for underground installation.
