Deso 1000 Litre Slimline Bunded Heating Oil Tank
The DESO SL1000BT 1000 Litre Slimline Bunded Oil Tank is a practical and dependable solution for storing heating oil where installation space is limited.
With a narrow width of approximately 645mm, the SL1000BT is designed to make efficient use of restricted spaces while still providing a useful 1000 litre, approximately 220 gallon, storage capacity. Its slim profile makes it particularly suitable for domestic gardens, narrow access areas and commercial premises where a conventional wider tank may not be practical.
Manufactured in the UK from premium-grade polyethylene, the tank provides excellent resistance to corrosion and outdoor conditions. The fully bunded tank-within-a-tank construction provides an additional layer of protection against leaks, helping keep stored fuel safely contained.
Supplied with essential fittings including an overfill prevention valve, inspection access, vent, 1" BSP bottom outlet and lockable access cover, the DESO SL1000BT provides a comprehensive solution for secure, long-term fuel storage.

Slimline Design for Restricted Spaces
One of the biggest advantages of the DESO SL1000BT is its narrow design.
At approximately 645mm wide, the tank can be positioned in locations where a wider conventional oil tank may not be suitable. This makes it particularly useful for properties with narrow gardens, pathways and restricted installation areas.
The slim profile also helps make efficient use of valuable outdoor space while retaining a full 1000 litre storage capacity.
Fully Bunded for Added Protection
The SL1000BT uses a tank-within-a-tank design to provide an additional level of protection for stored fuel.
The inner tank acts as the primary storage vessel, while the surrounding outer tank forms the secondary containment area. Should the inner tank develop a leak, the outer bund is designed to contain the escaped fuel.
This provides greater security than a traditional single skin tank and helps protect the surrounding property and environment.
Secure Lockable Access
The DESO SL1000BT features a lockable access lid, helping keep important tank fittings secure and protecting against unauthorised interference.
The lockable area provides convenient access when filling, inspecting or maintaining the tank while keeping the components protected during everyday use.

Overseas orders
International orders are welcome. Payment is by IBAN / SWIFT / BIC, MoneyGram and letters of credit. We regret that credit cards are not accepted for international orders.
A purchase order is required; we will then create a pro-forma invoice, and tanks are ordered on clearance of funds.
If you require additional export documentation — for example a Certificate of Origin, or commercial invoices certified by the Chamber of Commerce — you must notify us before completion of your order, as we will have to invoice cost and admin charges to the order.
