Frequently Asked Questions
What is the difference between a single skin and a bunded oil tank?
A single skin oil tank has one wall that contains the heating oil, whereas a bunded oil tank features an additional outer containment layer designed to retain fuel if the inner tank leaks.
Bunded tanks provide extra protection against accidental spills and environmental contamination.
The Carbery 650 Litre Single Skin Oil Tank is suitable for installations where secondary containment is not required or where an appropriate external bund is provided.
Before purchasing, check the installation requirements for your property, as a bunded tank may be necessary depending on the location and environmental risks.
Can I install this oil tank beside my house or in a small garden?
Its slimline design makes it a practical option for smaller gardens and properties with restricted outdoor space.
However, oil tanks must be installed at appropriate distances from buildings, boundaries, openings and potential fire hazards.
The required clearances depend on the installation and applicable fire safety and environmental regulations.
A competent oil tank installer should assess the proposed location before installation.
What type of base does the Carbery 650 Litre Oil Tank need?
The tank must be installed on a firm, level, non-combustible base capable of supporting its full weight when filled with heating oil.
The entire underside of the tank must be evenly supported, with no overhanging edges or unsupported sections.
Carbery installation guidance recommends a base extending at least 300 mm beyond the tank on all sides.
Suitable foundations and clearances should be confirmed by a competent installer, as incorrect installation can damage the tank and affect warranty coverage.
Can I fit an oil level gauge to this tank?
Yes, the tank includes a dedicated 32 mm connection point for a compatible electronic oil level gauge.
An electronic gauge can make it easier to monitor your remaining heating oil without opening the tank.
This is particularly useful during colder months when fuel consumption is higher and running out of heating oil could interrupt your heating supply.
The gauge should be selected to suit the tank and fitted according to the manufacturer's instructions.
How much heating oil can I actually put into a 650 litre tank?
Although sold as a 650 litre tank, this model has a nominal capacity of 611 litres and a brimful capacity of 643 litres.
The nominal capacity allows space above the fuel level rather than filling the tank completely to the brim.
When arranging an oil delivery, use the tank's nominal capacity and current fuel level to determine how much oil can safely be added.
Never deliberately overfill the tank, as heating oil requires sufficient space for expansion and safe storage.
How do I maintain a plastic heating oil tank?
Plastic oil tanks generally require relatively little maintenance, but regular visual checks are important to identify potential problems early.
Look for signs of cracks, distortion, leaks, damaged fittings or unusual movement around the tank base.
Keep the surrounding area clear of vegetation, rubbish and other materials that could obstruct access or inspection.
It's also sensible to have the tank and associated pipework inspected periodically by a competent oil heating professional, particularly as the tank gets older.
Following the manufacturer's maintenance and installation guidance will help protect the tank and maintain the conditions of its warranty.
