Frequently Asked Questions About Fuel Storage and Fuel Tanks

1593189006fuelstoragefaqs.jpg

What tank-size should I buy?

The size of the tank to install or purchase should be relative to your heating requirements, usage, budget, and property size.
 

What should I know before purchasing a fuel tank?

Fuel tanks come in a variety of designs and materials. Some are made from steel, some from plastic, whilst some are double skinned, some are single skinned, and others are bunded.

Between a steel and plastic oil tanks, most people choose plastic. This is because plastic tanks aren’t as susceptible to corrosion when compared to steel tanks. They are also light, easy to transport and affordable. On the other hand, steel tanks are preferred by customers who store large volumes of oil often over 10,000 litres as they are stronger.

Bunded fuel tanks and double skinned fuel tanks are similar in that they both have an outer tank to give the inner tank containing the fuel that extra protection. However, bunded fuel tanks are preferred as they are easier to clean if the tank is overfilled, with the double skinned tanks being extremely difficult to maintain. Double skinned tanks can only be used for a single product for safety purposes as they are not compatible for multiple.

If you are conscious of your budget and are only needing a single skinned fuel tank for a maximum of 2500 litres of fuel, you need to be aware that there are potential hazards such as fuel spillage. Your single skinned tank must not be placed near any open drains or controlled water and this is highly hazardous to the environment.

What is a bunded fuel tank?

It is simply a tank within a tank. The inner tank stores the oil while the outer one functions as a fail-safe in the event of spillage. Excess oil is collected in the bund. Bunded tanks are a requirement for industrial, commercial, and institutional premises.
 

Can I Install an Oil Tank?

The installation of oil tanks should be done by accredited and qualified tank technicians. Ensure that the installer is registered and licensed by OFTEC. Oil tanks store corrosive oil which can pollute the environment leading to more costs when the installation is not handled by a professional and qualified installer.
 

Are there any rules on tank location?

Yes, oil tanks should conform to fire separation distances to protect the stored fuel from a heat source, like fire, which may nearby. Oil tanks should be located:

  1. 1.8 metres away from:
  • any appliance fuel terminals
  • openings like windows and doors
  • non-fire-rated eves of a building
  • a non-fired rated structure or building like the garden shed
  1. On a solid level base and at least 42 millimetres thick, which extends to a minimum of 300 millimetres around the oil tank’s footprint
  2. 0.76 metres away from non-fire rated boundaries like a wooden fence

If these requirements aren’t possible, a fire-rated barrier should be used with at least 30 minutes protection, and 300 millimetres wider and higher than each applicable face of the oil tank. You can also install a fire-protected oil tank.
 

Can an oil tank be installed indoors?

Oil tanks should not be installed within inhabited, enclosed spaces. However, sometimes enclosed spaces are allowed in the cases of specialist enclosures that have been built and designed for such requirements.

Special requirements exist for installing oil storage tanks that are within habitable domestic garages and buildings.
 

Is a concrete base important?

No, but a concrete base that is designed correctly will increase the longevity of the oil tank and make sure the installation remains rigid and doesn’t become susceptible to movement which causes fractures in the tank structure and associated pipework.
